Two crystalline protoxins from Bacillus thuringiensis (Bt), Cry1Fa1 and Cry34Ab1/Cry35Ab1 (Cry1F, Cry34/ 35Ab1), were evaluated for efficacy against lepidopteran and coleopteran storage pests. Cry1F was tested against the lepidopterans Sitotroga cerealella (Angoumois grain moth) and colonies of Plodia interpunctella (Indian mealmoth) that are susceptible or resistant to Bt Cry1Ab and Cry1Ac tox...

Insecticidal fumigation toxicity of natural and synthetic cyanohydrins was evaluated with four stored-product pests: the lesser grain borer, Rhyzopertha dominica (F), the red flour beetle, Tribolium castaneum Herbst, the saw-toothed grain beetle Oryzaephilus surinamensis L, the maize weevil, Sitophilus zeamais (Motsch) and the house fly, Musca domestica L. The fumigation LC50 values were calcul...

Diatomaceous earth (DE) is a desiccant insecticide and most efficacious in low humidity. It acts on insect cuticle by absorbing lipids, and perhaps by cuticular abrasion. Beauveria bassiana (Balsamo) Vuillemin, an entomopathogenic fungus, is most efficacious in high humidity and has a complex interaction with cuticular lipids. Interaction between these materials may enhance insect control perfo...

هدف: RNA های غیرکدکننده از جمله مولکول تنظیم شناخته شده در سلول می باشند که فرایندهای مختلفی را کنترل کنند. مرتبط با مزبور، رشد و نمو تمایز سلولی باشد. این رو نقش آنها بروز تومور سرطان مختلف دست بررسی خصوص ارتباط مستقیمی بین ملکول مزبور دیده است. انواع غیر کد کننده ها، بلند (Long non-coding RNAs) باشند. گروه RNAها به‫عنوان کننده‌های کلیدی شده‫اند. ازجمله LncRNA MIAT یکRNA می‌باشد تقش انکوژنی آن...

Abstract Opportune and accurate identification of Date pests during storage, is prerequisite for reducing pest damages having a good export. The present study aimed to define new sampling method three main storage Oryzaephilus surinamensis (Linnaeus), Ephestia kuehniella (Zeller) Plodia interpunctella (Hübner) in date Deiri Cultivar, by Spectrophotometer. experiments were conducted completely r...

INTRODUCTION: The coral snake Micrurus surinamensis, which is widely distributed throughout Amazonia, has a neurotoxic venom. It is important to characterize the biological and molecular properties of this venom in order to develop effective antitoxins. METHODS: Toxins from the venom of M. surinamensis were analyzed by two-dimensional polyacrylamide gel electrophoresis and their neurotoxic ef...
