摘要
室内采用浸渍法测定了30%乙酰甲胺磷乳油、20%高氯·噻嗪酮乳油、240g/L螺螨酯悬浮剂和4.2%高氯·甲维盐乳油等4种杀虫剂对悬铃木方翅网蝽的杀卵效果。结果表明稀释浓度在900×以上的高氯·噻嗪酮和高氯·甲维盐对悬铃木方翅网蝽卵的防治效果均在80%以上,但高氯·噻嗪酮的防治药剂成本是高氯·甲维盐的3倍以上。各浓度处理的螺螨酯和乙酰甲胺磷的对卵的防治效果都很差,卵的孵化率均在70%以上。20%高氯·噻嗪酮乳油和4.2%高氯·甲维盐乳油对悬铃木方翅网蝽卵的孵化有抑制作用,在田间杀卵药剂选择中可参考使用。
Ovicidal effect of four pesticides including beta-cypermethrin·emamectin benzoate 4.2% EC,acephate 30%EC,beta-cypermethrin·buprofezin 20% EC and spirodiclofen 240g/L SC in the laboratory were tested to sycamore lace bug,C.ciliata with immersion method.The results showed that control effects of beta-cypermethrin·buprofezin and betacypermethrin·emamectin benzoate were both more than 80% when were diluted 900 times higher,but the cost of the former increased to more than three times as compared with the latter.Both acephate and spirodiclofen had a bad ovicidal effect that the hatching rate of egg were all more than 70%in each treatment.Beta-cypermethrin·buprofezin 20% EC and beta-cypermethrin·emamectin benzoate 4.2% EC has inhibitory effect on the egg hatching of C.ciliata,which provided an reference for the selection of ovicide in the field.
