[目的]明确对4种鳞翅目食叶害虫具有较好毒杀作用的药剂。[方法]用人工饲料混药法和浸虫浸叶法测定了几种杀虫剂对4种害虫的室内毒力,并模拟大田进行了药效试验。[结果]处理48 h,2%甲氨基阿维菌素苯甲酸盐SL对甜菜夜蛾、棉铃虫和斜纹夜蛾3龄幼虫的毒力均最高,LD50值分别为8.235、0.236、0.267滋g/g;10%高效氯氟氰菊酯EW对黏虫的毒力作用明显,LC50值达13.954 mg/L。模拟田间药效中2%甲氨基阿维菌素苯甲酸盐SL 1 500倍液和10%高效氯氟氰菊酯EW 3 600倍液的1颐1混剂效果最好,校正防效达99.39%。[结论]其结果可为筛选4种鳞翅目食叶害虫的理想防治药剂提供参考。 展开更多

Gypsy moth, Lymantria dispar (L.) is one of the most widespread defoliators of deciduous and larch forests in Kazakhstan. Preferred host plants, flying capacity of females and neonate caterpillars, preferred places for egg laying, major factors of mortality and other characteristics vary considerably between different populations of the pest. According to several year researches on gypsy moth, in Kazakhstan, the main biological characteristics of this pest in the regions were investigated. Results of research showed that gypsy moth exists in central and northern of theses regions. From biological and geographical aspects, gypsy moth which there is in Kazakhstan is close to the same species from Siberia western regions. The pest lays on the different heights of trees trunk. It was found that the number of eggs in each egg mass and egg masses laid by the pest are different. The lack of egg eaters and the over- reproduction of the pest at the natural conditions have resulted in the development of bacterial and viral diseases in the populations of this pest from the regions of Kazakhstan to Siberia west. 展开更多
