Insecticide 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 کاملBiochemical and Physiologial Characteristics of Insecticide Resistance in Diamondback Moth
A pyrethroid-resistant strain of the diamondback moth, Plutella xylostella (L.), originally collected in Thailand showed cross-resistance to all the pyrethroids tested. Upon further selection with fenvalerate in the laboratory, the strain exhibited an extremely high LD50 value, 41 μg/larva, for fenvalerate. In genetic studies of the resistance, the F1 progeny showed recessive gene(s), while the...
متن کاملGlutathione S-transferases and insecticide resistance of diamondback moth
The role of glutathione S-transferase (GST, EC 2.5.1.18) in the degradation of and resistance to some insecticides of diamondback moth (DBM) larvae has been confirmed through the purification and characterization of its four isozymes from this notorious insect pest of cruciferous vegetables. Two immuno-related isozymes, GST-3 and GST-4, exhibit apparent substrate preference for 1,2-dichloro-4ni...
متن کاملAssessment of insecticide resistance after the outbreak of diamondback moth (Lepidoptera: Plutellidae) in California in 1997.
During an outbreak of the diamondback moth, Plutella xylostella (L.), in California in 1997, nine populations were collected from the major broccoli areas throughout the state. Populations were assayed for their susceptibility to currently used materials (Bacillus thuringiensis subsp. kurstaki, permethrin, and methomyl) and to newer materials that had not yet been commercially used in Californi...
