The Control of Diamondback Moth with Thuricide
نویسندگان
چکیده
Thuricide, a Bacillus thuringiensis formulation, is active against more than 200 lepidopterous species in their larval stage. Best efficacy is obtained when Thuricide is applied at hatching time and/or on 1st to 3rd larval instars during their intensive feeding period. Since Thuricide must be eaten by the insect to be effective, thorough leaf coverage is essential for best results. Thuricide HP is used in most areas of Asia where diamondback moth (Plutella xylostella L) is a serious pest. In our trials in Malaysia, Indonesia, India, and Australia, this product has given control of diamondback moth comparable to or better than standard organophosphorus insecticides. Thuricide has no adverse effect on hymenopterous parasites of diamondback moth.

متن کاملDeltamethrin resistance in some diamondback moth, Plutella xylostella populations in Iran
The diamondback moth, Plutella xylostella has been developed resistance to many groups of pesticides including of pyrethroids. The present study was conducted to evaluate the toxicity of deltamethrin on the third instar larvae of six populations of the pest using leaf dipping method. The results showed that different populations had different susceptibilities to deltamethrin. At the LC50 level,...
متن کاملHymenopterous Parasitoids Associated with Diamondback Moth: the Taxonomic Dilemma
Attempts to control diamondback moth Plutella xylostella (L.) using insect parasitoids have not been entirely successful. Parasitoids which have been utilized include Diadegma species and Cotesia plutellae. A better understanding of the systematics of these Hymenoptera could lead to their more effective exploitation in biological control. Diadegma is a very large and difficult genus of lchneumo...

Laboratory, greenhouse and field studies were conducted on Oomyzus sokolowskii Kurdjumov, a parasite of diamondback moth, Plutella xylostella (L.), to judge its suitability for introduction in the field to control the plutellid. Oomyzus sokolowskii preferred the third and fourth instar diamondback moth larvae over fresh pupae for parasitization. It is thus a larval parasite. Within the range of...
