Reference excerpt

The Insecticide Resistance Action Committee (IRAC) was formed in 1984 and works as a specialist technical group of the industry association CropLife to be able to provide a coordinated industry response to prevent or delay the development of insecticide resistance in insect, mite and nematode pests. IRAC strives to facilitate communication and education on insecticide and traits resistance as well as to promote the development and facilitate the implementation of insecticide resistance management strategies. IRAC is recognised by the Food and Agriculture Organization (FAO) and the World Health Organization (WHO) of the United Nations as an advisory body on matters pertaining to insecticide resistance. Pesticideresistance.org is a database financed by IRAC, US Department of Agriculture, and others.

Sponsors IRAC's sponsors are: ADAMA, BASF, Bayer CropScience, Corteva, FMC, Mitsui Chemicals, Sumitomo Chemical, Syngenta and UPL.

Mode of action classification IRAC publishes an insecticide mode of action (MoA) classification that lists most common insecticides and acaricides and recommends that "successive generations of a pest should not be treated with compounds from the same MoA Group". IRAC assigns a mode of action (MoA) to an insecticide, based on sufficient scientific data. They then update the mode of action (MoA) classification. Several insecticides and classes of insecticide may act through the same mode of action.

Classes of insecticide If an insecticide is successful, follow-on insecticides, based on the chemical structure of the first in class (prototype) insecticide, may be developed either by the original company or by competitors. Sought after are insecticides which have improved properties or which kill different orders or species of insect. The resulting classes of insecticides are named by IRAC after common usage has been established, although alternative names may be found in the scientific literature.

Table of modes of action and classes of insecticide In the table the number of insecticides listed in each class is given, and an example of each class. The number of insecticides in the IRAC class listing as of 2024 is given in column Nr (A). The number in the Compendium of Pesticide Common Names (insecticide + acaricide) is given in column Nr (B), although the name given there to the class historically is often different to the IRAC class name.

Worked examples

Example 1 — a first encounter with Insecticide Resistance Action Committee

Start with the simplest possible case. Write down what Insecticide Resistance Action Committee claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Insecticide Resistance Action Committee before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Insecticide Resistance Action Committee ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Insecticide Resistance Action Committee

In research: Insecticide Resistance Action Committee appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Insecticide Resistance Action Committee in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Insecticide Resistance Action Committee is common in secondary-school and first-year university syllabi. It links to neighbouring topics Biotechnology advocacy groups, Insecticides, Organizations established in 1984, so understanding it makes those chapters shorter.
In everyday life: Look for Insecticide Resistance Action Committee outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
