Sublethal 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...
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 کاملLaboratory Evaluation of Commercial Trichogrammatid Products for Potential Use against Plutella xylostella (L.) (Lepidoptera: Plutellidae)
In laboratory experiments we compared the mortality of Plutella xylostella L. eggs induced by six products of trichogrammatid egg parasitoids. Five of the species were commercially available, and the sixth is under development. Each of the six products represented a single species of trichogrammatid (Trichogrammatoidea bactraeNagaraja,Trichogrammapretiosum Riley, T. ostriniae Pan & Chen, T. pla...
متن کاملSusceptibility of Plutella xylostella (L.) (Lepidoptera: Plutellidae) populations in Mexico to commercial formulations of Bacillus thuringiensis.
Populations of diamondback moth, Plutella xylostella (L.), sampled from commercial fields of crucifers in three states of Mexico, were tested for susceptibility to commercial formulations of Bacillus thuringiensis subsp. kurstaki (Berliner) (Dipel 2X), B. thuringiensis subsp. aizawai (XenTari), delta endotoxin Cry 1C (MC), and CryIA(c) (MVP), and a mixture of B. thuringiensis subsp. kurstaki an...
متن کاملNew records of natural enemies of Plutella xylostella (L.) (Lepidoptera: Plutellidae) in Pernambuco, Brazil.
We report the occurrence of natural enemies of Plutella xylostela (L.) in organically farmed kale in Pernambuco, Brazil. Seven natural enemies were observed parasitizing or preying on larvae and pupae of P. xylostella--three parasitoids: Cotesia plutellae Kurdjumov (Hym.: Braconidae), Conura pseudofulvovariegata (Becker) (Hym.: Chalcididae) and Tetrastichus howardi (Olliff) (Hym.: Eulophidae), ...
