EVALUATION OF RELEASE OF Diaeretiella rapae (M´ INTOSH) FOR CONTROLLING THE CRUCIFEROUS APHID, Brevicoryne brassicae L. ON CAULIFLOWER PLANTS AT SHARKIA GOVERNORATE, EGYPT.

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...

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

Host quality of different aphid species for rearing Diaeretiella rapae (McIntosh) (Hymenoptera: Braconidae).

This study aimed to evaluate the quality of the aphid Myzus persicae (Sulzer), Lipaphis erysimi (Kaltenbach) and Brevicoryne brassicae (L.) as hosts for the parasitoid Diaeretiella rapae (McIntosh). Parasitization by D. rapae was higher on M. persicae than on L. erysimi and B. brassicae. The time of development of D. rapae from egg to mummy or egg to adult male or female were shorter on M. pers...

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...

مطالعه برخی از خصوصیات رفتاری زنبور Diaeretiella rapae پارازیتوئید شته مومی کلم Brevicoryne brassicae

در این تحقیق برخی از خصوصیات رفتاری زنبور Diaeretiella rapae (McIntosh) پارازیتوئید شته مومی کلم Brevicoryne brassicae(L.) مورد مطالعه قرار گرفت . هدف از انجام این تحقیق ارزیابی میزان کارایی زنبور D. rapae از طریق مطالعه خصوصیات رفتاری واکنش تابعی، ترجیح مرحله سنی میزبان و تاثیر تراکم های مختلف زنبور روی قدرت جستجوی آنها (تداخل ) بود. آزمایش ها در شرایط دمایی 1?25 درجه سانتیگراد ، رطوبت نسبی 5...
