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...
متن کاملInsecticide 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 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...
متن کاملGenetic differentiation among various populations of the diamondback moth, Plutella xylostella (Lepidoptera: Yponomeutidae).
Genetic variation among 14 populations of Plutella xylostella (Linnaeus) from USA (Geneva, New York), Brazil (Brasilia), Japan (Okayama), The Philippines (Caragan de Oyo), Uzbekistan (Tashkent), France (Montpellier), Benin (Cotonou), South Africa (Johannesburg), Réunion Island (Montvert), and five localities in Australia (Adelaide, Brisbane, Mareeba, Melbourne, Sydney) were assessed by analysis...
متن کاملSublethal Effects of Fenoxycarb on the Plutella xylostella (Lepidoptera: Plutellidae)
The effects of fenoxycarb, a Juvenile hormone analogue, at sublethal concentrations were tested on some biological parameters of Plutella xylostella (L.) in two consecutive generations. The calculated LC10, LC25, and LC50 values of the insecticide were 21.58, 43.25, and 93.62 mg/liter on third-instar larvae, respectively. Fenoxycarb significantly reduced pupal weight and oviposition period in p...
