Pyrethroid susceptibility and oxidative detoxification mechanism in Colorado potato beetle and western corn rootworm

The Colorado potato beetle (CPB) and the western corn rootworm (WCR) are among world’s most expansive insect pests. aim of study was to assess, for first time in Poland, levels susceptibility to deltamethrin tau-fluvalinate WCR determine current status those active substances CPB. In addition, role oxidative metabolism detoxification pyrethroids was determined using piperonyl butoxide (PBO). found pyrethroid resistance CPB populations. populations exhibited “high susceptibility”, “susceptibility”, “low resistance” “medium tested. Experiments PBO showed that enzymes involved mechanism CPB, although effectiveness this Poland is decreasing. be highly toxic findings from should taken into account when developing a strategy prevent development pest species. results toxicity Polish demonstrated inhibited by important metabolic processes, which considered innovative control methods pest.
