Insecticide Resistance in Plutella xylostella (L.) (Lepidoptera: Yponomeutidae) in the Federal District, Brazil
The levels of resistance to the insecticides cartap, deltamethrin and metamidophos were evaluated for three populations of the Diamondback Moth Plutella xylostella (L.) from the Federal District, Brazil in laboratory bioassays. The larvae of DBM showed levels of resistance to deltamethrin between 4 and 47 fold relative to a susceptible laboratory strain. The level of resistance to metamidophos ...
متن کاملInsecticide resistance in populations of the diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae), from the state of Pernambuco, Brazil.
The diamondback moth Plutella xylostella (L.) has a great economic importance in Brassicaceae crops in many parts of the world. Recurrent infestations of this pest in growing areas of Pernambuco state, Brazil, have led farmers to frequently spray their crops with insecticides. However, control failures by several insecticides have been alleged by farmers. The objective of this study was to chec...
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...
متن کاملStudies on genetic variability of Diamondback moth, Plutella xylostella (Lepidoptera: Yponomeutidae) in Himachal Pradesh
Studies were carried out during 2015 and 2016 at Nauni, Solan, Himachal Pradesh to determine the genetic variability of Plutella xylostella (Lepidoptera: Yponomeutidae) in Cauliflower. The diamondback moth population collected from 4 locatitons viz. three from Himachal Pradesh and one from Punjab revealed significant variability existing among them. The life table analysis revealed that the fem...
