چکیده
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 قرار گرفتند. برای هر رشدی، 22 بوته بوته، سرشاخه انتهایی دور آن توسط کلنی شته‌‌ها کامل پوشانده شده بود، واحد انتخاب گردید. نتایج نشان داد روش‌های شته مستقیم، اختلاف معنی‌داری داشتند. ولی هیچگونه بین عکس‌برداری مشاهده نشد. اساس، داشتن بالاترین ضریب تصحیح (790/0)، تبیین (9315/0) دقت خالص نسبی (RNP) 56/51، بهترین دقیق‌ترین جهت مومی‌کلم معرفی شد. اساس یافته‌های پژوهش، یک صحیح زمان مناسب، می‌تواند برنامه‌های مدیریت تلفیقی را ارتقاء بخشد.

Purification and characterization of myrosinase from the cabbage aphid (Brevicoryne brassicae), a brassica herbivore.
Aphids are among the most serious insect pests of agricultural crops in the world. They often have specific hosts, and the cabbage aphid (Brevicoryne brassicae) is a specialist on Cruciferae. It has previously been described that certain insects contain the enzyme myrosinase (EC 3.2.3.1), which is considered an important defence enzyme of crucifers. Myrosinase was purified to homogeneity from c...
متن کاملPurification 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...

to estimate population density of the cabbage aphid, brevicoryne brassicae (l.), a stratified random sampling was conducted in two unsprayed canola fields in isfahan (central iran) during 2011-2012. population density was determined for apterous, and alates, as well as the total population, at two plant growth phases (pgp1: from plant emergence to the end of rosette, and pgp2: from the beginnin...
متن کاملCytogenetic analysis on the holocentric chromosomes of the cabbage aphid Brevicoryne brassicae
Chromatin organization in the holocentric chromosomes of the aphid Brevicoryne brassicae has been investigated at a cytological level after C-banding, NOR, Giemsa, DAPI and CMA3 staining. C-banding technique showed the presence of heterochromatic bands on both telomeres of the two X chromosomes, whereas only the longest pair of autosomes show distinct intercalary C-positive bands. Moreover, sil...
