Rapeseed (Brassica napus L. ssp. oleifera Metzg) is attacked by a wide range of pests. Breeding resistant cultivars one the best methods protecting crops against insects, and non-cultivated species Brassicaceae can be used as resistance donors. In this study, we investigated relationship between nutrient content to two commonly occurring pests (Delia radicum Brevicoryne brassicae) in 12 hybrid ...

شته مومی کلم (Brevicoryne brassicae L.)، یکی از آفات کلیدی و اقتصادی گیاهان خانواده چلیپائیان در جهان می‌باشد که اثرات مخربی بر روی کلزا (Brassica napus به همراه داشته است. این تحقیق، منظور تخمین دقیق جمعیت کلم، سه روش نمونه‌برداری (عکس‌برداری، اندازه‌گیری میانگین طول ساقه آلوده وزنی شته)‌ عنوان تیمارهای اصلی با شمارش مستقیم تیمار شاهد مرحله غنچه‌دهی، گل‌دهی غلاف‌دهی طور جداگانه، مورد مقایسه قر...

Brassica napus is an economically important crop across different continents including temperate and subtropical regions in Europe, Canada, South Asia, China and Australia. Its widespread cultivation also brings setbacks as it plays host to fungal, oomycete and chytrid pathogens that can lead to serious yield loss. For sustainable crop production, identification of resistance (R) genes in B. na...

In 1990 and 1991, populations of the cabbage aphid, Brevicoryne brassicae, and the green peach aphid, Myzus persicae, were monitored on broccoli interplanted with three leguminous cover crops (the living mulches) and compared with broccoli without cover crop (clean cultivation). The cover crops used were white clover ( Trifolium repens L.), strawberry clover (Trifolium fragiferum L.) and a mixt...

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...

A Basidiomycota endomycorrhizal fungus, Piriformospora indica Verma, colonizes and promotes the growth of canola (Brassica napus L.) other Brassica crops can reduce diseases crops. Clubroot is an important disease caused by obligate, soil-borne pathogen Plasmodiophora brassicae Woronin. The effect P. on clubroot severity in was assessed replicated room studies. Seed treated with using a proprie...

The aphids control (Brevicoryne brassicae L.) in kale (Brassica oleracea L. var. acephala) is one of the main challenges for its production. This obstacle becomes greater agroecological production systems. Thus, objective this study was to verify formation winged individuals colonies B. aphids, when exposed treated with homeopathic solutions. treatments were resistant 5CH, susceptible attacked ...
