AIMS To present the pairwise comparison of potential mosquito-pathogenic Bacillus strains based on their SDS-PAGE protein patterns and to evaluate their characteristic toxicity patterns. METHODS AND RESULTS In this work, 20 Bacillus strains were subjected to qualitative toxicity tests against Aedes aegypti and Culex quinquefasciatus larvae. The selected strains were then characterized by SDS-...
Aedes vexans is known to occur in large populations riverine floodplains much of Europe, where it can cause a significant biting nuisance and often subject scale control strategies. Until recently had only been reported very small numbers the United Kingdom. After receiving reports near river Idle, Nottinghamshire (East Midlands, England), mosquito surveillance was conducted over three years (2...

با توجه به این‌که دوبالان پوسیده خوار از آفات داﺋمی سالن‌های پرورش قارچ خوراکی هستند، به‌ناچار بهره بردارن از سموم شیمیایی به‌طور مکرر استفاده می‌کنند. کارگران سالن‌های پرورش قارچ و مصرف‌کنندگان قارچ خوراکی همواره در معرض تهدید سموم شیمیایی هستند، لذا معرفی روش‌های غیرشیمیایی و بیولوژیک ضروری است. این پژوهش در قالب دو آزمایش در شرایط آزمایشگاه و مزرعه انجام شد. در آزمایشگاه فرمولاسیون تجاری بای...
Mendelian crosses were used to study the mode of inheritance of Cry toxin resistance in a Culex quinquefasciatus Say (Diptera: Culicidae) colony (CqAB11A) that evolved insecticide resistance under laboratory selection with a deletion mutant of Bacillus thuringiensis subsp. israelensis de Barjac lacking the Cyt1Aa toxin component but containing its three major Cry toxins, Cry4Aa, Cry4Ba, and Cry...
In this study, susceptibility of the first three larval stages of Spodoptera exigua to Bacillus thuringiensis was investigated. To determine the LC50 values for each larval instar, 6 different logarithmic concentrations of Bacillus thuringiensis were used. A control was also included in each of the bioassays. The value of LC50 for 1st instar larvae, that had been treated one to four hours after...
