“…31,32) The increase in activities of esterases 19,33) and cytochrome P450 [34][35][36] had been reported to be one of the most important mechanisms for imidacloprid resistance in many insects. However, reduced penetration of an insecticide through the insect cuticle is not considered an important resistance mechanism.…”

The imidacloprid-resistant strain of Aphis gossypii (RF 60 ) was further selected with imidacloprid to establish the more resistant strain (RF 75 ). After the selection for 15 generations, the resistance ratio relative to the susceptible strain increased from 66.60 to 72.60. The RF 75 strain showed different levels of cross-resistance to all the insecticides tested. Synergistic and metabolic enzyme assays suggested that carboxylesterase and cytochrome P450 may play important roles in the imidacloprid resistance. © Pesticide Science Society of Japan

“…This was necessary to estimate the maximum evaluation time after bioassay assembly that causes 20% lower mortality in the control [18]. Thus, to have a mortality range from 0% to 100%, evaluations were made at 2, 6, 12, 16, 24, 32 and 48 h (treatments) after bioassay assembly.…”

Coffee leafminer Leucoptera coffeella is an important pest on coffee. The continued use of chemicals can result in loss of efficacy and selection of leafminer-resistant populations. We aimed to identify L. coffeella populations resistant to old and new neurotoxic insecticides in regions of Brazil. We collected seven populations of L. coffeella in Brazil. Low levels of resistance were observed for the insecticides chlorantraniliprole (1.02-3.23 times), abamectin (1.19-4.80 times), and deltamethrin (1.05-5.35 times). High resistance levels were observed for profenofos (65.3-522 times) and chlorpyrifos (4.53-18.63 times). We conclude that Brazilian L. coffeella populations showed greater resistance to organophosphate insecticides. Furthermore, resistance may be associated with the distance between the coffee-producing regions.

“…Despite the fact that the use of insecticides resulted in a drastic reduction of CPB populations, resistance development against the active substances has been observed. The CPB, through genetic adaptation, has been able to develop resistance to most of the registered insecticides (Grafius 1997;Stanković et al 2004;Alyokhin et al 2008;Sladan et al 2012;Szendrei et al 2012). Increasing the dosage provides only short-term relief, and greatly increases the rate of resistance development.…”

The Colorado potato beetle (CPB) is one of the pest insects that significantly can decrease the production of potato when no control measures are taken. The fast, flexible and diverse life cycle of the CPB, its highly destructive feeding habits, and high adaptability to a variety of environment stresses, have made the control of CPB a difficult task. This paper briefly reviews the information on all aspects of CPB management to come to an integrated pest management approach: the biology of the CPB, management practices including their limitations and drawbacks, as well as the need to incorporate host plant resistance into potato varieties. Several aspects of potato breeding for resistance to CPB are discussed. We evaluate the availability of natural variation present in potato wild relatives, the considerations in choosing a specific wild relative, and constraints in using them from biological, environmental and genetic point of view, in which newly developed technologies play an important role. We also consider recently developed GM approaches. We conclude that varieties resistant to CPB are desperately needed by farmers and demanded by society, and that the means to develop them are available.

Resistance to neonicotinoid insecticides in field populations of the Colorado potato beetle (Coleoptera: Chrysomelidae)

Abstract: The increasing resistance to neonicotinoid insecticides raises concerns for the continued effective management of Colorado potato beetles in potatoes and highlights the need for more rigorous practice of integrated pest management methods.
