Diamondback 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 کاملEvaluating trap crops for diamondback moth, Plutella xylostella (Lepidoptera: Plutellidae).
Potential trap crops for the diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae), were evaluated through a series of ovipositional preference and larval survival experiments in outdoor screenhouses in 2002 and 2003. Hosts examined as trap crops were glossy and waxy collards, Brassica oleracea L. variety acephala; Indian mustard, Brassica juncea (L.) Czern; and yellow rocket, B...
متن کاملProduction of Ice Nucleation Deficient (Ice-) Mutants of the Epiphytic Strains of Erwinia herbicola
To mutate the Ice Nucleation Active (INA) gene in Erwinia herbicola strains, Tn-5 transposon carried by Psup2021 plasmid was used. This plasmid was transferred to the bacterial cells by electroporation. Electrotransformation was carried out for 2.5 ms at 1800 v and 1 mm distance between the electrodes. Polymerase chain reaction was used for determination of presence or loss of INA gene, using a...
متن کاملDevelopment of genetic markers to study dispersal of Diamondback moth, Plutella xylostella (L.) in Australia
The origin and insecticide resistance status of Diamondback moth (Plutella xylostella) populations infesting canola, vegetables, forage brassicas and weeds has fundamental implications for management of the pest in Australia. Diamondback moth is considered a migratory species in the Northern Hemisphere, but although there is evidence that Diamondback moth moves en-masse throughout Australia in ...
متن کاملGlobal identification of microRNAs associated with chlorantraniliprole resistance in diamondback moth Plutella xylostella (L.)
The diamondback moth (DBM), Plutella xylostella (L.), is one of the most serious cruciferous pests and has developed high resistance to most insecticides, including chlorantraniliprole. Previous studies have reported several protein-coding genes that involved in chlorantraniliprole resistance, but research on resistance mechanisms at the post-transcription level is still limited. In this study,...
