…biology, the genetic basis of resistance (e.g., resistance mechanism, number of genes, number of alleles, functional dominance), the mode of action of the product, and the level of control of the pest by a given product can all influence the rate of resistance evolution and capacity to detect it. Most insecticides provide high levels of control of susceptible individuals in a population but may allow less susceptible (i.e., resistant) individuals to survive and pass that genetic trait to their offspring. …

…the field populations of Chilo suppressalis from Hubei and Anhui province increased significantly with the high resistance areas spreading further. Some cases of control failure of Nilaparvata lugens were observed in the field which raises some concern The 2021 Chinese version of the MOA Classification and IRM Guidelines for Sucking Pest were published and promoted Broflanilide, the first launched product from MoA Group 30, was widely used for control of Phyllotreta striolata and Plutella xylostella, but as there is no…
The Public Health Team was formed in 2006 to continue the work initiated by the previous IRAC Vector Team and has the extended remit covering hygiene pests as well as vectors. Most of the efforts have focused on forming links with key groups working in the vector control area (WHO, Bill and Melinda Gates Foundation BMGF and Innovative Vector Control Consortium IVCC). A key IRAC publication “Prevention and Management of Insecticide Resistance in Vectors and Pests of Public Health…

…chemical control with a limited number of effective insecticides available. This situation usually leads to increase in the frequency of use and thus, increase in the selection pressure. In fact, field populations of T. absoluta resistant to a range of mode of action groups are already known from L. America countries, where this has been a key pest for decades. T. absoluta is a pest of great economic importance in a number of countries. Its primary host is tomato, although…
…to acaricides very rapidly. As a result it is considered one of the “most resistant species” in terms of the total number of pesticides to which populations have become resistant, and its control has become problematic in many areas worldwide. Known resistances: Carbamates – Group 1A Avermectins, Milbemycins – Group 6 Clofentezine, Hexythiazox, Diflovidazin – Group 10A Oganotin miticides – Group 12B Acequinocyl – Group 20B METI acaricides & insecticides – Group 21A Unknown or uncertain MoAs – Group UN…
