The development of an IPM program for diamondback moth (DBM) in Malaysia comprised several distinct stages. These ranged from initial appraisal of the problem and examination of strategic options, to component identification, development and integration, and eventual evaluation of interim IPM

Plants release volatile chemicals upon attack by herbivorous arthropods. They do so commonly in a dose-dependent manner: the more herbivores, the more volatiles released. The volatiles attract predatory arthropods and the amount determines the probability of predator response. We show that seedlings of a cabbage variety (Brassica oleracea var. capitata, cv Shikidori) also show such a response t...

Use of Indian mustard (Brassica juncea (L.) Czern.) as a trap crop for management of diamondback moth, Plutella xylostella (L.), and leafwebber, Crocidolomia binotalis Zeller, was tried on an experimental farm and farmers’ fields. Preliminary studies indicated that planting of 15 cabbage rows followed by paired mustard rows to manage both pests was useful. The first mustard row is sown 15 days ...

Quinolactacide isolated from Penicillium citrinum F 1539 was synthesized and evaluated for its insecticidal activities. The key steps of the total synthesis were an acyl migration reaction of the enol ester intermediate and dehydrogenation of tetrahydroquinolactacide with manganese dioxide. The synthesized quinolactacide showed 100% and 42% mortality against the green peach aphid (Myzus persica...

Cruciferous crops on Guam are infested by cabbage webworm, Hellula undalis (F.), cabbage cluster caterpillar, Crocidolomia pavonana Zeller, mustard aphid, Lipaphis erysimi (Davis), armyworm, Spodoptera litura (F.), flea hopper, Halticus tibialis (Reuter), fire ant, Solenopsis geminata (F.), leaf miners, Liriomyza spp., diamondback moth, Plutella xylostella (L.), corn earworm, Helicoverpa armige...

With the discovery of the larval parasitoid, Cotesia plutellae Kurdjumov, and the successful introduction and establishment of two other exotic parasitoid species, viz. Diadegma semiclausum Hellen and Diadromus (Thyraeella) collaris Gravenhorst in the Cameron Highlands, biological control was given greater emphasis in the development of IPM for diamondback moth, Plutella xylostella (L.), in Mal...

Granuloviruses are widespread pathogens of Plutella xylostella L. (diamondback moth) and potential biopesticides for control of this global insect pest. We report the complete genomes of four Plutella xylostella granulovirus isolates from China, Malaysia, and Taiwan exhibiting pairs of noncoding, homologous repeat regions with significant sequence variation but equivalent length.
