| 摘 要： | 采用田间调查和室内饲养的方法,结合统计结果,分析了植物源复合杀虫剂对烟蚜的防治效果及对烟蚜天敌的影响。试验表明,植物源复合杀虫剂较理想的使用浓度是400倍液和600倍液,两种浓度对烟蚜都有明显的杀伤作用,对烟蚜天敌也无负面影响,其中400倍液效果稍好,但两者间差异不显著,推荐使用600倍液。

| Abstract: | The prevention and treatment effect of plan-d erived compound insecticide on tobacco aphid and on predators of tobacco aphid was studied by the method of field investigation and laboratory rearing,combining with statistical results.The experiment indicated that the ideal applied concentration of plant-derived compound insecticide was 400 times and 600 times,both of which had a significant killing effect on tobacco aphid,and no negative influence on predators of tobacco aphid.The effect of 400 times was slig... |
