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 کاملDeltamethrin 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 کاملGlucosinolate Profiles in Cabbage Genotypes Influence the Preferential Feeding of Diamondback Moth (Plutella xylostella)
Diamondback moth (DBM), Plutella xylostella L., is a devastating pest of cabbage worldwide whose feeding attributes are influenced by glucosinolate profiles of the plant. Identifying the specific glucosinolates associated with plants' resistance mechanism can provide cues to novel points of intervention in developing resistant cultivars. We studied the DBM larval feeding preference and extent o...
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 کاملCross-Resistance to Bacillus thuringiensis Toxin CryIF in the Diamondback Moth (Plutella xylostella).
Selection with Bacillus thuringiensis subsp. kurstaki, which contains CryIA and CryII toxins, caused a >200-fold cross-resistance to CryIF toxin from B. thuringiensis subsp. aizawai in the diamondback moth, Plutella xylostella. CryIE was not toxic, but CryIB was highly toxic to both selected and unselected larvae. The results show that extremely high levels of cross-resistance can be conferred ...
