As insects develop increased Ability to Survive and Thrive on Chemicals Used to Control Them, Insecticide Resistance Has Become One of the Greatest Threats Facing Farmers Today.

With each passing decade, farmers have been challenged to manage their Insects through the use of insecticides that provide maximum protection for their crops. As with any chemical application, most of the products used are applied to provide protection from the specific pest or disease. When used correctly, farmers expect the application of insecticides to provide full protection.

Over Time, Insects Have Adapted to the Regularly Applied Chemical Products by Developing Resistance and Quickly Finding Ways to Survive Off of the Chemicals that are Meant to Kill Them. The Adaptations can include Metabolic, Target Site, Behavioral, and Penetration Resistance, each of which presents New Challenges to Farmers.

Just as Different Varieties of Millets Provide Different Types of Nutritional Value, Each Strategy Used by Farmers to Control Resistance Will Provide Some Benefit to the Farmer. Farmers should work within their area of knowledge to provide Optimal Control of Resistance.

Understanding Insecticide Resistance: What It Is and Why It Occurs

For many pests, insecticide resistance develops gradually, similar to how a newborn grows into its new diet of solid foods. Once resistance occurs, however, the pest can withstand the previously effective insecticides that controlled its population. The process of developing resistance takes time, and is primarily due to repeated exposure to a particular insecticide, as well as environmental pressures, and the intrinsic genetic capability of some insects to adapt and survive against toxicants, which is why controlling these insect populations is becoming increasingly difficult.

Insecticide resistance definition

A major aspect of insecticide resistance is that it has the capability of surviving chemical products that were effective in the past to eliminate insects that had been treated with the insecticide.

• Resistance occurs when insects adapt to their environment by developing traits that give them some level of protection against the specific target of an insecticides.
• Over many generations, the insects are able to continually pass on this trait to future generations which increases the frequency of these traits in the overall insect population.
• As more and more insects become resistant to the pesticides, it becomes increasingly difficult for crop producers to manage and therefore crop production becomes less effective. Crop producers now have to either apply higher rates of pesticides or switch to different types of chemicals.

A very simple example of insecticide resistance begins with a small population; the first group of baby insects have developed certain traits that enable them to survive exposure to a specific type of chemical insecticide. If a farmer uses this insecticide frequently, eventually the only surviving insects that reproduce are those with the specific traits that protect them from being killed. With this continuous process of reproduction, over time the pest population as a whole will have developed the ability to resist that insecticide; this is termed full-scale insecticide resistance.

How insects become resistant

Insects acquire resistance to the same chemical pest-control product when pests are exposed multiple times to the same pesticide and create a selective advantage for those resistant insects.

• Thus, when pesticides are applied regularly, the sensitive insects are killed off, leaving behind only resistant insects to breed and pass on their ability to survive to future generations.

• The process speeds up as the same pesticide continues to be used against insects that are already resistant to that pesticide.

When a baby is born with high iron content (from pearl millet) and high fiber content (from pearl millet), it is like when a pest becomes "super" resistant to chemical treatments after they have been exposed multiple times to the same pesticide. The pest survives each pesticide use and stores the genetic information necessary for survival against stronger future pesticide applications. This is how many common pest insects (aphids, whiteflies, mosquitoes) develop pesticide resistance to pesticides used overly frequently and create long-term management issues.

Genetic adaptation and selection pressure

Insecticides exert "pressure" on pest populations and, as a result, insects evolve genetically to resist those chemicals.

Genetic adaptations may be attained by the pest in a number of different ways:

1. By mutation, genetic material being changed by modifying the insecticide action site;

2. By improving detoxification rates for the chemicals (insects that develop enzymes that break down the insecticide faster than usual);

3. By behaviourally modifying themselves so that they will not encounter the insecticide.

Just as different types of millets provide different types of nutrition at various growth stages for infants, so too do different types of insecticide resistance provide various means for insects to adapt themselves over time to improved fitness through environmental selection processes. Chemical adaptations result in a rapid increase in the strength of the pest population to survive against insecticides, and the resulting resistance is distributed rapidly to the remaining member of the population, eventually resulting in crop protection loss around the globe. 

The Impact of Insecticide Resistance on Agriculture and Public Health

Insecticide resistance impacts agriculture and public health through different ways that are connected. Just as millet affects the growth of babies, different types of pests convert into an increased problem for farmers to manage, increase their chances of failing as a result of producing less food and also affect the preventive capacity of crops by increasing the amount of illness. This section outlines the way that insecticide resistance affects the farm and family, similar to the breakdown of nutrients by type of millet.

Crop loss due to resistant pests

Similar to the millets that are mild and well tolerated by a baby's stomach, insecticides are also meant to be protective agents for crops. However, once pests develop resistance to insecticides, they can no longer be effectively controlled by the chemicals originally designed for that purposes.

Key Points

• Pests that have developed resistance can survive exposure to even the most potent insecticides.
• Crop quality and quantity are considerably reduced by damaged foliage, stems and fruits.
• Repeated attacks on farm crops during growing season puts considerable strain on farmers.

Pests can develop resistance to insecticides when their target sites can no longer bind to the insecticide due to the development of new mutant forms of the pest. As a result of developing resistance, these pests can rapidly reproduce and feed on their food source without being hampered by the insecticide. This results in a substantial reduction of crop production, especially for rice, cotton and vegetable and stored grain production. Resistance mechanisms involve the ability of the pest to either detoxify the insecticide via metabolic routes or prevent the insecticide from entering through target-site mutations, leading to increased crop losses and reduced yields causing farm communities to suffer serious financial strain.

Disease vector control challenges (mosquitoes, flies)

Whereas millets differ in their primary function—some supplying energy while others offer digestive support, the same is true for insecticides, which perform multiple functions including controlling mosquito and fly populations that carry diseases; this creates many challenges due to resistance.

Key Points

• Resistance to this method of controlling mosquitoes is developing at an alarming rate throughout the world.
• Diseases such as malaria, dengue, and chikungunya will be increasingly challenging to manage.
• As a result of this fact, public health organizations will need to implement increasingly complex and costly methods for managing these diseases.

Mosquitoes can become resistant to insecticide very quickly because of the capacity to change their resistance mechanisms (i.e., the molecular changes to their targets). Behavioral resistance (avoidance of insecticide-treated surfaces) is one of the most common types of resistance that results in less effectiveness of indoor residual spraying and fogging methods. Increased resistance has led to increasing rates of disease outbreaks, increased demand on healthcare systems, and diminished cost-effectiveness of control efforts.

Economic consequences for farmers and governments

Millets vary not only in their prices and availability but also their nutritional content; likewise the economic impacts of resistance vary with level of economic impact on the farmer and national agricultural budgets.

Key Points Examples

• Because farmers require more repeated applications to control pest populations, they will require more inputs.
• As double duty is now placed on governments to fund research, monitor resistance, and support public health.
• Resistance causes instability within agricultural markets and reduces the value of exportable crops.

Once insecticides have failed, the farmer will resort to increasing the frequency of sprays. Additionally, the farmer may need to purchase a stronger, more costly product. This affects production costs substantially while crop yields continue to decrease. In addition to higher costs for farmers, governments will incur increasing costs to continue financing research, developing new chemical products, and sponsoring vector control programs. For many developing countries struggling with Insecticide Resistance, the economic burden could ultimately disrupt entire food systems, increase food prices, and put food security at risk for the population.

Main Causes Behind the Rise in Insecticide Resistance

Around the world, insecticide resistance is rapidly increasing on farms, just as there are many types of millets that differ in texture and nutritional value from one another.

The various causes of insecticide resistance each serve a different function in terms of aiding pest adaptation and survival; therefore, these factors, when combined with other methods of pest control, make it progressively more challenging for farmers to contain pest populations. The table below contains answers to the common causes mentioned above in an ordered, mismatched format that is inspired by the example of millet.

Overuse and misuse of pesticides

Just as repeating the same food type can irritate the digestive system of an infant, spraying pesticides too often disrupts the natural balance of pest populations and creates the right atmosphere for rapid resistance development in those populations.

Theoretical Concepts:

1. As a result of the cumulative effects of increased exposure to pesticides, insects have many chances to develop resistance.

2. Under-dosed selections of pesticides (too little of the active ingredient) and/or overdosed selections of pesticides (too much of the active ingredient) create fluctuating levels of selection intensity and allow for survival of only the most resistant insects.

3. Continuous exposure to pesticides creates pressure on the insect population to evolve; thus, allowing for rapid adaptation by pest populations.

The most effective way to use pesticides is to avoid frequent pesticide applications. Use of a pesticide type too frequently exposes the target insect(s) to a chemical with which they have grown accustomed to and to which some individuals may become highly tolerant. Misuse of a pesticide due to improper dosing or applying it at inappropriate times promotes evolution in the insects adapting to survive, causing those surviving/propagating individual's genetic material to continue populating the pest population. Just as over time, infants expand their preference/tolerance toward certain types of foods due to their repeated exposure to these foods, pests evolve resistance to insecticides through repeated exposure to insecticides.

Using the same insecticide target repeatedly

Similar to how a baby on a diet of only one grain of millet will end up with less variety in nutrition than if fed a balanced diet with fruits and vegetables, using the same insecticide repeatedly allows for an insect pest to learn what to expect from that product, making it more likely that resistance will develop.

Key Points:

• Repeated exposure to the Same Mode of Action trains the insects to adapt.
• Target-Site Resistance is one of the main ways Insecticide Resistance occurs.
• The insects develop mutations in their target sites that block or weaken the binding of the Insecticide.

Many insecticides operate by targeting a specific site on an insect—like the receptor sites on the nerves or the sites where food is digested. The more often insects are exposed to these target sites, the more often they develop mutations that allow them to resist the effects of the Insecticide. This is referred to as "Target-Site Resistance," which is one of the most common forms of Insecticide Resistance. As time passes, farmers will see that their traditional Insecticides will lose effectiveness and thus, increase the risk for crop damage and loss.

Lack of chemical rotation

Similar to the way rotation of various types of millet provides a balanced diet for infants, rotating the use of different pesticides that work through different mechanisms will assist in controlling pest populations as well.

1. Without rotation, the same pesticide is repeatedly used by the same population of insects.

2. There is a higher risk of developing resistance across generations of insects.

3. By alternating the types of pesticides used, the rate of development of insecticide-resistant insect populations will be reduced.

The continuous exposure of insects to the same type of pesticide increases the chances of developing a stable, resistant population. As a result, the population will reproduce faster due to the elimination of all susceptible insects. Therefore, alternating among products with different targets for insecticides is akin to switching between various types of nutritious millets to achieve a balanced diet, to limit the potential for over-adaptation, and to result in healthier fields. While there is no rotation of pesticide types, the identification of types of resistance to different pesticides will develop much more quickly and reduce the effectiveness of even the best modern products.

Detecting and Monitoring Insecticide Resistance in Pest Populations

Monitoring insecticides to ascertain the presence of insecticide resistance to pest populations is similar to millets. There may be several varieties of millets, each supporting a different phase of a child’s development.

Detecting Insecticide Resistance (IR) can take many forms. Most methods are designed to help researchers, growers and policymakers identify early signs of resistance, and allow them to take corrective action before damage occurs that is beyond control.

Through laboratory-based assays or field sampling methodologies, one can determine not only how the pest is avoiding insecticidal action, but also what types of insecticide resistance the pest has developed.

Laboratory resistance testing methods

Testing performed in laboratories are referred to as "Ragi" for resistance detection purposes; they are accurate, simple, and typically the first tests performed to determine the level of any resistance that exists.

• Assists researchers in identifying the exact types of insecticides which have resistance to pest species.
• Measures how insect pests are able to survive exposure to insecticides at specific doses.
• Detects genetic mutations that lead to resistance development.
• Provides information for farmers to formulate superior plans for controlling pest populations.

Lab tests allow researchers to use controlled conditions to evaluate Resistance To Insecticides through Laboratory Conditions (RTIC). Insects are tested for resistance using various concentrations of chemicals to determine death rates and if a particular target insecticide is still an active ingredient. Commonly identified resistance mechanisms include metabolic, target site mutation(s) and protection from entry, as well as metabolic, target site mutation(s), or penetration. The results from laboratory testing have been used as a baseline for understanding resistance trends and subsequently assisting farmers and researchers in making better decisions.

Field bioassays and molecular markers

Field tests, also referred to as "Pearl Millet," may not have the same quality or refinement as the others, but they are still very valuable from a practical perspective because they help us understand the possible pest behavior variations we may encounter in the field.

1. Bioassays provide simulation of actual Farming Environment

2. Provide insight into how pests will respond when exposed to actual crops.

3. Molecular Markers allow the identification of the genes responsible for resistance at an early stage.

4. Can provide an effective method of monitoring at a regional scale.

Field Bioassay Tests allow us to gauge the effectiveness of insecticide treatments against Live Pests in their Natural Habitat/Situation. Field Bioassays also identify "Behavioural resistance---- a less obvious, but ultimately dangerous form of Insecticide Resistance." It occurs when a pest refuses to go onto a treated surface. Molecular Marker Methodologies provide complementary tool to Field Bioassays by allowing you to determine whether your pest has undergone any genetic changes related to resistance. By combining both methodologies, we will have similar insights and answers about how well we can expect the system to manage exposure when using Florin. The field tests provide Farmers with practical hands-on experience and knowledge to Adapt their Pest Management Practices Immediately.

Early warning surveillance programs

The practice of monitoring the behavior of pest populations continuously is referred to as 'Surveillance Programs'.

By having the Ability to Create Alerts and provide Authorities with Guidance, these Programs allow for the Following:

Create Alerts when Resistance Levels Increase.

• Maintain Accurate Records.
• Deliver Greater Numbers of Accurate Seasonal Patterns.
• Develop Region-Specific Alerts and Patterns.
• Provide Tools to Facilitate Management.

The use of traps, field sampling, participants' feedback, and digital tools enables Experts to effectively use Early Warning Systems for Monitoring the Resistance of pests.

Similar to the way Early Introductions of millets support the health of our Digestive System, By Using AV Prior to Pest Population Becoming Resistant, We Are Able to Introduce More Timely Control Mechanisms and prevent Resistances from Being Further Developed or Strengthened Later On!

By using the surveillance programs, Experts will be able to determine how the pest is evolving, and the insecticide's effectiveness at Targeting/Acting on the Pest. This allows the Experts to continuously monitor resistance levels of the pest and allows for the ability to draft Alerts Prior to All Have Become Resistant. This proactive monitoring protects crop Values and puts the Correct Controls into Effect Before It Is Too Late!

Innovative Strategies to Manage and Prevent Insecticide Resistance

Pest-protection methods for farms exist as per the stage of pest pressure just as different types of millets can nourish a baby depending on their physical and developmental growth. When combined, these techniques provide an important means to reduce insecticide resistance, conserve the insecticide target, and ultimately delay the accumulation of all forms of insecticide resistance.

The entries below are the most effective and acceptable pest-protection strategies for farms with the specific “nutrition value” that will make your farm healthy.

Integrated Pest Management (IPM)

Farmers can reduce pesticide resistance by rotating between "new," effective insecticides and not just within pesticide classes, but through total rotations using various pesticides with completely different modes of action (insecticides targeting nerves vs. insecticides targeting muscle). The 

main benefits of rotating insecticides include:

1) Allowing pests to experience total loss of the ability to resist insecticides (similar to our baby finding it boring to eat the same food every day and wanting to eat other foods),

2) Eliminating repetitive exposure to the same active ingredient and different brand formulations (in the same class),

3) Reducing the chance of a pest passing on resistant genes to other pests.

4) Allowing the development of a less specialized population of resistant insects and improving their chances of survival (compared to more specialized populations of resistant insects), when developing a more diverse population of resistant insects.

5) Improving the long-term success of the crop protection program.

Rotating insecticides with different modes of action

IPM is like the 'Ragi' of pest control: it is full of benefits and is the 'first recommendation' because it helps to reduce insecticide resistance.

• An integrated pest management system is an integrated approach that reduces the chance of developing Insecticide Resistance by simultaneously managing pest populations at a low level.
• IPM reduces the need for pesticide applications, thereby improving soil health and protecting beneficial insects.
• Integrated Pest Management provides a holistic way to lower pest populations while reducing the likelihood of insecticide resistance developing.

By using Integrated Pest Management (IPM) in conjunction with proper pesticide use, you can reduce the number of times you spray a single field, thus avoiding multiple opportunities for pests to be in contact with the same insecticide. When you use IPM in combination with proper pesticide usage, you will reduce your risk of developing insecticide resistance within your pest populations.

Using biological control agents

Bio Controls operate the same way as “Little Millet” and “Barnyard Millet" – mild, gentle, and suitable for sensitive systems.

Bio Controls Include:

• Beneficial Insects, Fungi, Bacteria, Viruses
• Reduced Chemical Spray Cycles.
• Maintaining Biodiversity in Fields.
• Preventing Pest Resistant Generational Cycle.

Ladybugs, Trichoderma fungi, Bacillus thuringiensis, and parasitic Wasps are biological agents that promote natural pest suppression. Just as mild millets can be used to feed babies who have sensitive stomachs, Biological Controls are also effective in supporting ecosystems that have been stressed by over-use of synthetic chemicals. Using biologicals to reduce our need to use synthetic sprays decreases the amount of time a pest will be exposed to a chemical, preventing it from adapting and developing additional types of insecticide resistance. Biologicals also provide a protective environment for beneficial agents, allowing the ecosystem to find its own balance without constant chemical intervention.

The Role of Research, Innovation, and Policy in Combating Resistance

Resistance to insecticides is rapidly expanding globally. All crops, including insects, go through several stages on their way to becoming a market product, and consequently, all scientific, regulatory, and technological advances will work in concert to support those systems. The need to fortify pest control methods, slow down the development of resistance, and increase sustainable agricultural practices all require coordinated efforts.

Government regulations on pesticide use

The role of government regulations acts as a filter and ensures that only the safest, most efficient insecticides are delivered to farmers. They ensure that farmers, consumers, and the environment are protected from the harmful effects of chemicals that potentially create insecticide-resistant pests.

What are the key factors?

• Government agencies approve or disapprove insecticides based on the degree of toxicity and other hazard evaluations.
• Government agencies create and enforce limits for residues left on plants after treatment to protect consumers from possible harmful exposure.
• Well-developed and enforced pesticide regulations are significant in preventing the inappropriate use of products that might lead to further evolution of Insecticide Resistance.

The existence of training programs provides assistance to agricultural producers in selecting the appropriate target insecticide and applying it safely.

With strong pest management regulations, pesticides applied in the field have less potential to become resistant pests. Agricultural producers that do not adhere to established application intervals, dosage rates, and approved products have a higher probability of developing insecticide-resistant pest populations. This regulation of insecticides is critical to safeguarding public health and agricultural production. Pesticide regulations result in replacing hazardous pesticides with less hazardous alternatives, which is similar to providing the appropriate type of millet to meet the delicate digestion needs of a baby.

Research into new insecticide targets

Insecticides of the next generation are similar to Kodo or Foxtail millet—although created with advanced technology, the targeted and precise approach is in line with modern agriculture needs. This means that they can be designed for use without causing as much environmental damage or harming even the most difficult of pests to eliminate.

Key Features:

• Safe to use.
• Target only a few pests at one time.
• Can be used on insects that have developed resistance.

Next-generation insecticides were developed through an extensive and thorough effort to find solutions to all of the major issues that have developed associated with the issue of insecticide resistance. Next-generation insecticides attach to specific target sites on insects that have not yet been affected by pesticide resistance. In addition, the vast majority of the new molecules break down in nature more quickly than traditional insecticides. Hence, next-generation insecticides have less negative impact on the environment than traditional insecticides—they will eventually be replaced with traditional insecticides as agriculture becomes safer and more efficient.

Next-generation insecticides

Insecticides created today, called ‘next-generation insecticides,’ are comparable to NEW ENTRANCE MILK. They're being developed as the new level of pest management with the latest technology to be highly effective and precise at protecting against the largest and most challenging agricultural pest problems.

General Points

• These products will be designed to be less harmful to people, animals, and beneficial insects.
• These products will only target specific pests and therefore have little or no effect on non-target insects.
• These products remain effective even on insects that have become resistant through development.
• The use of biological controls with next-generation insecticides is expected to increase sustainable pest control through the minimization of chemical inputs and by providing the full range of pest management options.

Next-generation insecticides were developed after extensive research to find new and innovative methods for addressing all of the current problems associated with Insecticide Development. By developing specific chemical target sites and targeting these sites, the next-generation insecticides are designed to provide maximum control with minimal harm to humans, animals, and beneficial soil-related organisms, etc. Moreover, the next-generation insecticide molecules have a much quicker rate of degradation than previous generations of insecticides, allowing them to provide a comparable level of protection, whilst minimizing their impact on the environment. As Kodo and Foxtail millet are specifically created to provide highly concentrated energy, so too do the next-generation insecticides provide highly specialized and effective solutions for pest management.

Conclusion: Act Now to Safeguard Our Crops and Health from Insecticide Resistance Threats!

Insecticide Resistance has now moved from an abstract idea to an immediate risk in all facets of agriculture and public health. Farmers suffer due to lost yields from insects that are too genetically resilient to miticides and farmers grow less productive due to the increased insect population—and communities face increased disease burden from vector-borne diseases when pest's genetic resilience is more extensive than the destruction caused our chemical methods of controlling insect populations. Thus the issue of Insecticide Resistance is larger than just a field issue because it has implications at the national and international levels for Food Security, Livelihoods and the Health of all humans. To be able to address Insecticide Resistance we must first know how it develops, spreads, and reduces the efficacy of Pest Control.

Like crops require nutrients to thrive, Managers of Insecticide Resistance must apply the appropriate strategies of application at the appropriate points in time. This includes Utilizing Insecticides with Care, Rotating Insecticide Target Species, Preventing Excessive Use & Employing Integrated Pest Management (IPM) as the Standard Method of Operation. By employing Biological Control Options, Improved Application Techniques and Scientific Developments we can slow down the expansion of all types of Insecticide Resistance and maintain the efficacy of the pest management technologies that are essential to Farmers, Researchers & Government. An Urgent Call-to-Action is in place now more than ever!
