Insecticide Resistance in Plutella xylostella (L.) (Lepidoptera: Yponomeutidae) in the Federal District, Brazil

چکیده
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 was 2-9 fold greater than that of the susceptible strain. No resistance to cartap was detected.

Photoperiodism 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...

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...
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 کاملInvestigations into the development of cross-tolerance in the Diamondback Moth (Plutella xylostella L., Yponomeutidae: Lepidoptera) to the entomopathogenic fungus Beauveria bassiana (Bal.) Vuillemin (Deuteromycotina: Hyphomycetes) and the toxin Dipel of Bacillus thuringiensis
The present research represents the first investigations into the development of crosstolerance in the larvae of Diamondback Moth (DBM) tolerant to Bacillus thuringiensis toxin (Bt-toxin: Dipel) and treated with different concentrations of the entomopathogenic fungus Beauveria bassiana (strain BbGHA). Significant differences (at P = 0.05) were obtained between the fungus concentrations used for...
