“…Insecticide resistance is a widespread phenomenon whereby insects that are subjected to intense chemical treatment may evolve mechanisms to protect themselves, and hence are able to survive and pass their resistance genes on to their offspring 1. Resistance can then spread quickly through insect populations by virtue of short generation times and high rates of fecundity 2.…”

A microencapsulated formulation that gives a burst release of piperonyl butoxide (PBO) several hours before a burst release of a conventional pyrethroid can effectively overcome metabolic resistance in Bemisia tabaci Gennadius, Helicoverpa armigera (Hübner), Aphis gossypii Glover and Myzus persicae Sulzer. This increase in efficacy against resistant pests was reflected in a field trial against B. tabaci on cotton, eliminating the need for two treatments. The ratio between the active insecticide and the synergist was found to be crucial in reducing resistance factors.

“…Перший випадок появи резистентних особин зафіксовано у 1908 р. в США у каліфорнійської щитівки до вапняно-сірчаного відвару, пізніше -у яблуневої плодожерки до препаратів миш'яку. Нині це явище має глобальний характер: у світі зафіксовано випадки розвитку резистентності у більше ніж 500 видів членистоногих до пестицидів різних хімічних класів, у тому числі iнгiбiторiв синтезу хiтину, гормональних i мiкробiологiчних препаратів [2,3].…”

Goal. To study the toxicity of the modern variety of insecticides from different classes of chemical substances at the level of the mean concentration (СК50, %) of the active substance for the common cereal aphids, cabbage flea, rape blossom weevil, common spider mite. Based on these data to determine the rate of resistance of natural populations of these species of phytophagous arthropods to insecticides. Methodology. The sensitivity of phytophagous arthropods was studied on natural populations collected on crops of winter wheat, canola, soybeans in the Kiev region in 2015—2018. For the poisoning of cereal aphids and mites using the method of immersion of the populated lists wheat and soybeans, and flea beetles and pollen beetle — dip them in a gauze bag for 3 seconds in the appropriate solution of insecticides. Were taken 24 hours after poisoning. Toxicological parameters were calculated by using Proban. Results. Identifies the different sensitivity of the natural arthropod populations to current insecticides. In terms of the mean concentration (СК50, %) of the active substance rapeseed pollen beetle were most sensitive to Configure, while the rest of the drugs is almost the same. Over the years research is more resistant to Decis Profi turned ordinary spider mites. This pest was a higher resistance. Conclusions. The sensitivity of arthropods to insecticides of different chemical classes depends on the characteristics of the pest and the properties of the drug. Indicators of resistance are determined by the biology of the phytophage and terms of use of insecticide. The highest PR was observed for polyvoltine species (aphids, mites). Low levels of resistance to phytophagous pyrethroid insecticides can be explained by two factors: a smaller volume of use or reversion (return of chuvstvitelnosti to the initial level).

Colorado potato beetle is one of the most important pests of potatoes and one of the most difficult insects to control. Over the years, none of the control techniques developed against this pest has provided long-term protection for potato crops. Worldwide, CP" is resistant to all major groups of insecticides, including organophosphates and carbamates.The target site of organophosphate OP and carbamate insecticides is the same they inhibit the activity of "ChE. The function of acetylcholinesterase "ChE is degradation of acetylcholine "Ch -neurotransmitter in the insect cholinergic synapses. Mutations in the "ChE-encoding locus have been shown to confer target site insensitivity to organophosphate and carbamate insecticides, leading to modification of "ChE M"CE . " range of other amino acid substitutions in "ChE confer insecticide resistance, and these mutations typically reside near to or within the active site of the enzyme. Such "ChE mutations, associated with insecticide resistance, mostly known as "ce in Drosophila, have also been observed in other species, including L. decemlineata. "ased on bioassays and literature, modified/insensitive "ChE confers two major patterns of resistance to OPs/ carbamates. Pattern I resistance is characterized by significantly higher resistance ratios RR much greater reduction in the sensitivity of "ChE at the biochemical level to carbamates than to organophosphate insecticides. Pattern II resistance is characterized by resistance ratios and/or reductions in the sensitivity of "ChE that are approximately equivalent for both carbamates and OPs. There are also a few species for which an insensitive "ChE has been reported and for which molecular data have been collected, but for which the resistance profiles for both OPs and carbamates have not been reported. For CP", both patterns were registered.
