Modern methods of stored wheat grain protection from insect pests strive towards optimizing the use of different techniques and methods within integrated pest management (IPM) programs. One of the methods of integral grain protection is the application of natural originating insecticides. The potential of the natural origin synthetic insecticide abamectin (a product of soil bacteria, Streptomyces avermitilis fermentation) on the grain borer, Rhyzopertha dominica F. (Coleoptera: Bostrichidae), in stored wheat, barley, ray, oats, and triticale was evaluated. The evaluation was conducted in 3 rates. The effects of its application on the infestation of R. dominica on certain physical and chemical traits of cereal grains were examined. The efficacy of abamectin after 7 days of exposure, in all applied dosages, was low (< 56.5% in wheat and < 30.5% in other grains). Abamectin efficacy was significantly increased after 14 days of exposure. R. dominica mortality was 99.0 and 100% after 21-day exposure at the abamectin rates of 0.5 and 1.0 mg kg−1, respectively. Ten weeks after grain treatment, the 3 examined rates prevented the emergence of progeny. The amount of the damaged grains and dockage, as a nus-product of feeding of R. dominica larvae and imago, compared to the untreated, infested sample was significantly smaller, which represents a positive aspect of abamectin application. The application did not change significantly the moisture, protein, and ash contents, in comparison to the control. Positive aspects of the abamectin application on different grain species (wheat, barley, rye, oats, and triticale) caused the highest rates of R. dominica mortality after 21 days of exposure where a total prevention of progeny emergence and absence of changes on technological grain properties occurred.

阿维菌素对小grain虫Rhyzopertha dominica F.（Coleoptera：Bostrichidae）侵染某些贮藏谷物的影响

储存小麦籽粒免受害虫侵害的现代方法致力于在虫害综合治理（IPM）计划中优化使用不同技术和方法。整体谷物保护的方法之一是天然来源杀虫剂的应用。评估了天然蛀虫合成杀虫剂阿维菌素（土壤细菌，阿维链霉菌发酵的产物）在小麦，大麦，，燕麦，黑小麦和黑小麦中储存的bore虫Rhyzopertha dominica F.（鞘翅目：Bostrichidae）的潜力。评估分为3个等级。考察了其对多米尼加罗非鱼侵染对谷物某些理化特性的影响。在所有施用剂量下，阿巴菌素暴露7天后的功效均很低（小麦中<56.5％，<30。其他谷物中则为5％）。暴露14天后阿维菌素的疗效显着提高。暴露于阿玛菌素的0.5和1.0 mg kg-1的21天暴露后，多米尼加罗非鱼的死亡率分别为99.0和100％。谷物处理后十周，三个检查的比率阻止了子代的出现。与未处理，受感染的样品相比，作为多米尼加幼虫和凤梨喂养的正产物的受损谷物和码头的数量要少得多，这代表了阿维菌素应用的积极方面。与对照相比，该施用没有显着改变水分，蛋白质和灰分含量。阿维菌素在不同谷物种类（小麦，大麦，黑麦，燕麦和黑小麦）上的积极应用导致最高的R发生率。
