One of IRAC’s key roles, coordinated by the Outreach (formerly Communication & Education / C&E) Team, is the dissemination of information that will promote good IRM practices around the world. This is done through the generation of printed (posters, handouts, etc.) and electronic (website, eTools, etc.) educational material that can be used by a wide audience. Members of IRAC are encouraged to give presentations and hold poster sessions at national and international meeting and conferences. A wide range of…
The three core areas of activity for IRAC are traditional Crop Protection, Plant Biotechnology and Public Health. Crop Protection is the area where historically IRAC has been most active and over the years there have been a number of different Working Groups focussing on various potential resistance issues or tackling these as they arise. Currently there are three Working Groups sitting as part of the Crop Protection Team: Chewing Pests, Sucking and Piercing Pests and Nematodes. Further information and…
The IRAC Network is made up of a series of inter-company Committees dedicated to prolonging the effectiveness of insecticides and acaricides by countering the development of resistance. The Committees operate at a global level (IRAC International and IRAC Executive) and at a regional or country level (IRAC Country Groups). IRAC as an organisation can only be successful with proactive participation and contributions from the member company representatives, volunteering their time and energies to achieve the agreed goals and objectives….
Worldwide there are approximately 4,500 species of cockroach (also referred to as “roaches”) of which about 30 are associated with human habitats. Of these 3 are well known pests – the German cockroach Blattella germanica is about 15 mm long when fully developed, and light brown in coloration, while the Oriental cockroach Blatta orientalis is shiny black and about 25 mm long. The largest of the three is the American cockroach, Periplaneta americana, which is dark brown and can be…
Tsetse flies are robust flies ranging from 6 to 15mm in length with a passing resemblance to house flies. There are 23 species belonging to the genus Glossina, all found only in Africa south of the Sahara. They can be distinguished from other flies by looking at their wings, which lay completely over each other at rest, and have a characteristic shaped pattern of wing venation, with a “cell” in the centre of their wings in the shape of a…
Nilaparvata lugens adults occur in macropterous (long-winged) and brachypterous (short-winged) forms. The macropterous form is about 3.5 – 4.5 mm in length. The body is brown, and the wings are transparent, with very conspicuous veins. Young nymphs are white, but they gradually become darker in older instars. Both nymphs and adults penetrate the tissues of their rice host plants with their piercing-sucking mouthparts in order to ingest phloem-sap. Loss of nutrients and obstruction of vessels cause yellowing of lInsecticide Resistance…
(Download the information as a pdf file) What is insecticide resistance modelling and who uses it? One of the most common questions asked of insecticide resistance researchers is “How long will it take for insecticide resistance to occur?” One way to answer this questions is to look at past events and identify trends that may repeat. This can be informative, but limited to general trends. For example in the crop protection market, it is often predicted that a pest…
The IRAC Mode of Action Classification The definitive, global classification scheme on the target sites of acaricides and insecticides The IRAC Mode of Action (MoA) classification is an essential tool for growers, advisors, extension staff, consultants and other crop protection professionals. It guides the selection of appropriate acaricides and insecticides for use in effective and sustainable resistance management (IRM) strategies.
