Transmission possibility of the fungus Beauveria bassiana KCF102 by mating behavior between Sunn pest, Eurygaster integriceps (Hem.: Scutelleridae) adults
Authors
Abstract:
در این پژوهش، امکان انتقال افقی جدایه‌ای از قارچ Beauveria bassiana KCF102 با رفتار جفت‌گیری بین افراد نر و ماده‌ی سن گندم، Eurygaster integriceps Put.، بررسی شد. همچنین، برای تعیین میزان حساسیت افراد نر و ماده و بخش‌های مختلف بدن سن گندم به این قارچ؛ شاخک‌ها، پنجه‌ها، سطح شکمی شکم، پیش‌گرده و کل بدن به عنوان تیمارهای آزمایشی انتخاب شد. نتایج حاصله نشان داد که بین افراد نر و ماده از نظر حساسیت به قارچ B. bassiana اختلاف معنی‌دار وجود ندارد. بین تیمارهای مربوط به آزمایش انتقال افقی قارچ، اختلاف معنی‌دار وجود داشت و این نشان داد که انتقال افقی قارچ بین افراد بالغ می‌تواند صورت گیرد اما عدم وجود اختلاف معنی‌دار بین تیمارهای با اختلاط نر آلوده با نر غیر‌آلوده و ماده‌ی آلوده با نر غیر‌آلوده، گویای این مطلب است که این نوع انتقال، با رفتار جفت‌گیری بین افراد نر وماده بروز نمی‌کند بلکه صرفاً تماس فیزیکی بین افراد بدون وابستگی به جنس، موجب این انتقال است. بین تیمارهای مربوط به حساسیت قسمت‌های مختلف بدن، اختلاف معنی‌داری مشاهده شد؛ تیمار پیش‌گرده با میانگین 6/16 و تیمار کل بدن با میانگین 9/48 درصد مرگ و میر، به‌ترتیب کمترین و بیشترین حساسیت را در بین تیمارهای انتخاب شده داشتند.

Sunn pest is one of the most important cereal pests that affect both grain yield and quality of cereal in Iran. One potential control strategy is to use entomopathogenic fungi such as Beauveria bassiana Vuillemin as mycoinsecticide to control this pest. Naturally infested Sunn pests in Kermanshah province were collected and brought to laboratory. 10 isolates were selected for further analysis i...

In this study, five morphological types of circulating hemocytes were recognized in the hemolymph of the adult sunn pest, Eurygaster integriceps Puton (Hemiptera: Scutelleridae), namely prohemocytes, plasmatocytes, granulocytes, adipohemocytes, and oenocytoids. The effects of the secondary metabolites of the entomopathogenic fungus Beauveria bassiana on cellular immune defenses of Eurygaster in...

The Sunn pest, Eurygaster integriceps Puton (Heteroptera: Scutelleridae), is one of the most important pests of wheat and causes considerable damage to this valuable crop annually. Digestive proteinase activity of adult insects was investigated using general and specific substrates and inhibitors. Proteolytic activity was low when the common conventional substrates, azoalbumin, azocasein and he...

The susceptibility of adult sunn pest, Eurygaster integriceps Puton (Hemiptera: Scutelleridae), to five local Syrian isolates of Heterorhabditis bacteriophora, Steinernema riobravae Texas, S. carpocapsae C3B, and H. bacteriophora 8-14 strains was evaluated under laboratory conditions. Concentrations of 50, 100, 200, and 400 nematodes per adult were bioassayed; for each nematode concentration, f...
