Effects of Synergists on the Toxicity of Fenvalerate to Pyrethroid-Resistant Diamondback Moth
Synergism of fenvalerate with piperonyl butoxide (PB), NIA-16388 (NIA), S-421, and MGK-264 on both susceptible (S) and fenvalerate-selected (FS) strains of diamondback moth, Plutella xylostella L, were determined in laboratory tests. Further, combinations of fenvalerate and these synergists were tested for their efficacies against resistant strain under field conditions in the Cameron Highlands...
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 کاملDiamondback moth, Plutella xylostella (L.), resistance management in Hawaii
Resistance to spinosad insecticide in field populations of diamondback moth was discovered at Kunia, Hawaii, in November 2000, about two and a half years after its introduction. Leaf-dip assays of field populations from the islands of Oahu, Maui and Hawaii confirmed moderate to high levels of resistance compared with pre-introduction baselines. Resistance occurred despite label restrictions tha...
متن کاملDifferent cross-resistance patterns in the diamondback moth (Lepidoptera: Plutellidae) resistant to Bacillus thuringiensis toxin Cry1C.
Two strains of the diamondback moth, Plutella xylostella (L.), were selected using Cry1C protoxin and transgenic broccoli plants expressing a Cry1C toxin of Bacillus thuringiensis (Bt). Both strains were resistant to Cry1C but had different cross-resistance patterns. We used 12 Bt protoxins for cross-resistance tests, including Cry1Aa, Cry1Ab, Cry1Ac, Cry1Bb, Cry1C, Cry1D, Cry1E, Cry1F, Cry1J, ...
متن کاملQTL analysis for diamondback moth resistance in canola (Brassica napus L.)
Diamondback moth (DBM), Plutella xylostella L. is the most injurious defoliage insect pest of canola in Ardabil province of Iran. It occurs annually and causes damage in canola fields. This study was performed to identify QTLs controlling resistance to diamondback moth using SSR and RAPD markers. An F2:4 population of 180 families derived from crossing between cv. ‘SLMO46’ and cv. ‘Quantum’ wer...
