高效渗透剂筛选及其与甲氧虫酰肼配伍毒杀舞毒蛾卵的效果

摘要

为提高杀虫剂对舞毒蛾（ Lymantria dispar）卵的毒杀效果，比较了快速渗透剂T、氮酮、杰效利3种渗透剂的渗透性能，及其对杀虫剂甲氧虫酰肼的增效作用。3种渗透剂的渗透性由强到弱依次为：杰效利、渗透剂T、氮酮。以1％杰效利分别与6个质量浓度梯度的甲氧虫酰肼（2．4×10-1、2．4×10-2、2．4×10-3、2．4×10-4、2．4×10-5、2．4×10-6 mg· L-1）配伍成高渗药剂，对舞毒蛾卵进行毒杀试验。结果表明：用1％杰效利处理后，舞毒蛾卵的孵化率为40．14％；用甲氧虫酰肼＋1％杰效利处理后，舞毒蛾卵的孵化率为19．95％～51．83％；它们均显著低于对照，但二者间差异不显著。由此可见，杀虫剂和渗透剂配伍的高渗药剂对舞毒蛾卵的孵化有明显的抑制作用。%The experiment was conducted to compare the infiltration capacity of penetrant T, azone, Jiexiaoli and their synergy to methoxyfenozide to improve the effect of pesticides to gypsy moth eggs.The order of their infiltration capacities are Jiexiaoli>penetrant T>azone.Then, the hypertonic agents composed of 1% of Jiexiaoli and six contents of methoxyfenozide (2.4× 10-1, 2.4×10-2, 2.4×10-3, 2.4×10-4, 2.4×10-5 and 2.4×10-6mg/L) were used for controlling gypsy moth eggs.The hatchability of gypsy moth eggs is 40.14%after the eggs are treated with 1%of Jiexiaoli, and the egg-hatchability is 19.95%-51.83%after the eggs are treated with the different concentration of hypertonic agents including methoxyfenozide .Their egg-hatchability with 1% of Jiexiaoli and hypertonic agent treatments is significantly lower than that of control, but the differences between 1%of Jiexiaoli and hypertonic agent treatments are not significant.Therefore, the hypertonic agents of the compatibility of medicines with pesticide and penetrant can obviously control the hatch ability of gypsy moth eggs.
