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 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,...
متن کاملFeeding preference of Plutella xylostella for leaves treated with plant extracts.
Plutella xylostella L. is one of the main agents to cause damages to plants of Brassica genus, provoking negative impacts in cultures. The use of botanical extracts in plants protection has been related in literature, however, their use in the species analyzed in this study is not yet reported. We assessed the effect of aqueous and methanolic extracts of the species: Schinus terebinthifolius Ra...
متن کاملParasitoids associated with the diamondback moth, Plutella xylostella (L.), in the Eastern Cape, South Africa
Seasonal fluctuations of diamondback moth and its hymenopteran parasitoids were recorded weekly from April 1997 to November 1999 at four cabbage sites in the Grahamstown area of the Eastern Cape, South Africa. Two sites were commercial farms with active spraying programmes; the others were unsprayed. Infestation levels were highest during spring (September to November) and autumn (March to May)...
متن کاملPhotoperiodism and seasonality in neotropical population of Plutella xylostella L. (Lepidoptera: Yponomeutidae).
Neotropical populations of the diamondback moth Plutella xylostella L. have seasonal cycles of growth and decrease, and moth migration plays a fundamental role in generating such population dynamics. Since the oscillation of these populations is predictable, photoperiod might operate as a signal that triggers the migratory behaviour of the insect. Migration in insects is usually preceded by rep...
