Diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae), has become the most destructive insect pest of cruciferous vegetables (Brassica oleracea L.) worldwide, and is a continuing problem especially in the southern United States. Because of inconsistencies in individual control methods, inefficiencies and time demands of scouting, and the lack of clear thresholds, current managem...

one species of eulophidae, oomyzus sokolowskii (kurdjumov), was collected from larvae of the diamondback moth, plutella xylostella (l.) (lep.: plutellidae). this parasitoid is a major gregarious larval-pupal endoparasitoid of p. xylostella that prefers ovipositing into host larvae but depositing its eggs in host prepupae too. this is the first report of the occurrence of this species from iran.

Abstract Known as the diamondback moth, Plutella xylostella L. is registered one of most important pests Brassicaceae in world. It characterized a specialized insect this family, due to specifics for feeding. However, based on reports from producers, shoots sour passion fruit extreme south Santa Catarina, were damaged by phytophagous attack. The damage plants collected and this, it was possible...

Mass rearing methods on artificial diets and cruciferous seedlings for the diamondback moth, Plutella xylostella L, are reviewed and described briefly.

The diamondback moth (DBM), Plutella xylostella (L.), costs the Chinese economy US$0.77 billion annually, and considerable research has focused on its biology, ecology, and management. Much of this research has been published locally and is inaccessible outside China. Since 1990 Brassica vegetable production has increased 20-fold and production practices have intensified, but losses continue to...

Fraxinellone, a well-known and significant naturally occurring compound isolated from Meliaceae and Rutaceae spp. has been widely used as a drug for the treatment of tumors. On the other hand, fraxinellone exhibited a variety of insecticidal activities including feeding-deterrent activity, inhibition of growth, and larvicidal activity. The present study focused on the antifeedant and larvicidal...

Plants are part of biodiverse communities and frequently suffer from attack by multiple herbivorous insects. Plant responses to these herbivores are specific for insect feeding guilds: aphids and caterpillars induce different plant phenotypes. Moreover, plants respond differentially to single or dual herbivory, which may cascade into a chain of interactions in terms of resistance to other commu...

The impact of three different doses of botanical insecticide derived from the syringa tree, Melia azedarach and the neem tree, Azadirachta indica was tested on the behaviour of the diamondback moth, Plutella xylostella (Linnaeus). Both botanical insecticides had a significant impact on larval behaviour. At higher doses the extracts showed feeding deterrent activity, with larvae preferring the u...

Laboratory experiments were conducted to examine selection by Cotesia plutellae between host larvae feeding on two plant species: Chinese cabbage, Brassica campestris ssp. pekinensis and common cabbage, Brassica oleracea var. capitata. When C. plutellae wasps were provided with equal numbers of Plutella xylostella larvae on both species of plants in one arena, the parasitoid parasitised 4-15 fo...

Many parts of the Calotropis gigantea plant are known to contain bioactive compounds, but leaves most. This study aimed determine toxicity and antifeedant activity C. against Plutella xylostella. The was carried out from November 2019 July 2020. Toxicity tested using leaf dipping spraying methods. Antifeedant a no-choice test choice test. Identification compound composition extract at Integrate...
