Resistance of Cabbage Aphid, Brevicoryne brassicae (Linnaeus) to Endosulfan, Organophosphates and Synthetic Pyrethroids

Development and Adoption of Integrated Pest Management for Major Pests of Cabbage Using Indian Mustard as a Trap Crop

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 ...

Factors Affecting Abundance and Damage Caused by Cabbage Aphid, Brevicoryne brassicae on Four Brassica Leafy Vegetables: Brassica oleracea var. Acephala, B. chinense, B. napus and B. carinata

Resistance of four brassica leafy vegetables: kale, Chinese cabbage, rape and Ethiopian mustard to cabbage aphid, Brevicoryne brassicae (L.) was studied in cage experiments at the Botswana College of Agriculture, Gaborone, Botswana. A completely randomised design with cultivars as treatments and four replicates per treatment was used. One newly laid nymph was placed on each of the four potted p...

Evaluation of soil-applied systemic insecticides against cabbage aphid,brevicoryne brassicae and resultant survival of the primary parasitoid diaeretiella rapae on cabbage

Functional response and mutual interference of Diaeretiella rapae (Hymenoptera: Aphidiidae) on Brevicoryne brassicae (Homoptera: Aphididae)

Functional response and mutual interference are the most important behavioural characteristics that reveal different aspects of host–parasitoid interactions. In this study, functional response and mutual interference of the parasitoid wasp, Diaeretiella rapae (M’Intosh) attacking the cabbage aphid, Brevicoryne brassicae (Linnaeus) were investigated. Logistic regression was used to distinguish t...

Purification and characterisation of a non-plant myrosinase from the cabbage aphid Brevicoryne brassicae (L.).

Plant myrosinases and glucosinolates constitute a defence system in cruciferous plants towards pests and diseases. We have purified for the first time a non-plant myrosinase from the cabbage aphid Brevicoryne brassicae (L.) to homogeneity. The protein was N-terminally blocked and protease (trypsin and lys c) degradation gave peptides of which five were sequenced. The protein is a dimer with sub...
