Effect of Intercropping and Trap Cropping on the Diamondback Moth, Plutella Xylostella L., Its Natural Enemies and Other Brassicaceous Pests, And, Studies on Diadegma Insulare (Cresson), the Major Diamondback Moth Parasitoid
Laboratory studies on D. insulare revealed that it was better synchronized with its host when it developed in second instars, where survival to cocoon formation and adult emergence was also significantly higher than in third- or fourth-instar hosts. A greenhouse study at varying parasitoid and host …

The colonisation of canola crops by the diamondback moth, Plutella xylostella L., in southern Australia
… creates uncertainty around species identity. The diamondback moth, Plutella xylostella L., the most destructive pest of Brassica crops worldwide, seasonally colonises winter canola crops in southern Australia leading to intermittent outbreaks. Little is known about regional movement and crop …

Contributions toward the integrated pest management of diamondback moth, Plutella xylostella (L.), on collards in Virginia
Diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae) is a serious pest of crucifer vegetables (Brassica sp.) worldwide because of a lack of effective natural enemies in certain regions and because of insecticide resistance. In 2003, laboratory and field studies were initiated in …

A study of the parasitism efficiency of Cotesia Vestalis (Haliday) on Diamondback Moth, Plutella Xylostella(L.),(Lepidoptera:Plutellidae)
The diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae) is an insect pest of cruciferous crops in the world including Zambia. It causes 52 – 92% loss in marketable produce in India. Control of P. xylostella has mainly depended on use of insecticides. However, the pest has …

Interrelationship of Bacillus thuringiensis Berliner to diamondback moth, Plutella xylostella L. (Lepidoptera: Plutellidaae), and its primary parasitoid, Diadegma insulare Cress (Hymenoptera: Ichneumonidae)
The susceptibility of a population of diamondback moth, Plutella xvlostella L (Lepidoptera: Plutellidae), collected from Montgomery County, Virginia, and its ability to develop resistance to Bacillus thuringiensis was evaluated. The field population of diamondback moths was found to be susceptible …

The role of foliar glucosinolates in host plant resistance of oilseed rape and mustard to the Bertha armyworm and the diamondback moth
… levels of an oligophagous insect, the diamondback moth, Plutella xylostella L. were investigated. M. configurata reared on eight rape and mustard varieties had significantly different final weights by species order Brassica juncea <Sinapis alba < B. napus < B. rapa. In choice tests, B. …

Evaluation of the potential of Pteromalus puparum (L.) (Hymenoptera: Pteromalidae) for suppression of the imported cabbageworm and parasitism of the diamondback moth
… looper <i>Trichoplusia ni</i> (Hubner)) and diamondback moth (<i>Plutella xylostella</i> (L.)) was determined in 1982 to 1984 on cabbage in southwest Virginia. The imported cabbageworm was the most important pest. It had one and a partial second generation in 1982 and 1983, and two and a …

Functional characterisation of the honeybee Apis mellifera and diamondback moth Plutella xylostella α5 nicotinic acetylcholine receptor identifies a subset of ion channels with unusual pharmacological properties
… of Hymenoptera (e.g. bees) and Lepidoptera (e.g. moths and butterflies) form a clade distinct to that of Diptera (e.g. flies and mosquitoes) α5 subunits. This prompted an investigation into whether Hymenoptera α5 nAChRs show distinct pharmacological properties. Here, we confirm preliminary …

Establishment of COTESA VESTALIS (HALIDAY) and DIADROMUS COLLARIS (GRAV.) parasitoids of the DIAMONDBACK MOTH, PLUTELLA XYLOSTELLA (L.), and assessment of the effectiveness of C. VESTALIS as a biological control agent in Zambia
… during the 1970s and 1980s, to control the diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae), a serious pest of vegetables in Zambia, and to assess the effectiveness of one of the released parasitoids, C. vestalis, as a biological control agent of the pest. Confirmation …

Sublethal effects of Bacillus thuringiensis Berliner on the diamondback moth, Plutella xylostella (L.), and its natural enemy, Cotesia plutellae Kurdjumov : implications for resistance management / by Lynne Grbin.
… behavioural interactions among the diamond-back moth, Plutella xylostella L. (Lepidoptera: Plutellidae), Cotesia plutellae Kurdjumov (Hymenoptera: Braconidae) and the microbial insecticide, Bacillus thuringiensis Berliner. A deterministic simulation model is developed describing the influence of …

The Evolutionary Ecology of Arabidopsis Thaliana: Genotypic Diversity, Herbivory, and Elevated Carbon Dioxide
… provided evidence that herbivory by the diamondback moth, Plutella xylostella, can modify the fitness response of A. thaliana to enriched CO2 conditions. Even though elevated CO 2 significantly enhanced plant fitness in the absence of herbivores, diamondback moth herbivory either …

The impact of allelopathic winter rye (Secale cereale L.) and hairy vetch (Vicia villosa Roth) residues on a vegetable cropping system
… had significantly greater infestations of diamondback moth, imported cabbageworm, and cabbage looper than in RT plots. Rye and hairy vetch residues also inhibited weed growth. Redroot pigweed (Amaranthus retroflexus L.) accounted for 60 to 80% of the total weeds. Initial (2 wk) weed control …

Efficacy of indigenous pesticidal plants for tomato and brassica pest management in Malawi
… incidence of red mites, aphids and diamond back moth significantly. Although synthetic insecticides were most effective against these pests, the pesticidal plant extracts examined offered valuable contribution to pest management efforts. T. diversifolia was the most effective at reducing numbers …
