Deltamethrin resistance in some diamondback moth, Plutella xylostella populations in Iran
The diamondback moth, Plutella xylostella has been developed resistance to many groups of pesticides including of pyrethroids. The present study was conducted to evaluate the toxicity of deltamethrin on the third instar larvae of six populations of the pest using leaf dipping method. The results showed that different populations had different susceptibilities to deltamethrin. At the LC50 level,...
متن کاملInsecticide Resistance in Diamondback Moth
High levels of resistance to the major categories of insecticides, ie, organophosphorus, carbamates, pyrethroids, and DDT, have been detected in the diamondback moth in Taiwan. Synergist studies have provided insufficient evidence to show significant involvement of known metabolic systems, such as microsomal oxidation, esterase hydrolysis, and glutathione conjugation in organophosphorus and car...
متن کاملInsecticide Resistance Characteristics of Diamondback Moth
Resistance to organophosphorus, carbamate and pyrethroid insecticides in the diamondback moth, Plutella xylostella (L.) is widespread in Japan. Consequently, tertiary amines such as cartap and thiocyclam, microbial insecticides (formulations of Bacillus thuringiensis Berliner) and chitin synthesis inhibitors have been widely used for control. A high level of resistance to these alternative inse...
متن کاملDiamondback Moth Resistance to Bacillus thuringiensis in Hawaii
Resistance to the microbial insecticide Bacillus thuringiensis Berliner has evolved in field populations of diamondback moth, Plutella xylostella (L.), in Hawaii. Three field populations that had been treated repeatedly with commercial formulations of the sporecrystal protein complex of B. thuringiensis subsp. kurstaki developed significant resistance to it. The LC50 of the most resistant popul...
متن کاملStable expression and functional characterisation of the diamondback moth ryanodine receptor G4946E variant conferring resistance to diamide insecticides
Diamides, such as flubendiamide and chlorantraniliprole, belong to a new chemical class of insecticides that act as conformation-sensitive activators of insect ryanodine receptors (RyRs). Both compounds are registered for use against lepidopteran species such as the diamondback moth, Plutella xylostella, a notorious global pest of cruciferous crops. Recently acquired resistance to diamide insec...
