摘要
通讨药剂对柞蚕的残毒期试验,初步确定50%马拉硫磷乳汕对柞蚕的残毒期为5天;80%敌敌畏乳油、50%辛硫磷乳油为7天;60%敌马合剂为9天;10%二氯苯醚菊酯为25天。经初步调查尚未发现上述药剂对柞蚕场天幕毛虫的天敌有杀伤作用。
Through experiments,it was found that the period of residual toxicity
harmful to tussah varied with different pesticides.The toxicity lingering
period was 5 days for the emulsion of 50% malathion,7 days for the emul-
sion of 89% DDV and the emulsion of 50%phoxim,9 days for the 60% M-
D mixture,and 25 days for the 10% permethrin.Preliminary investigations
showed that the pesticides mentioned above had no harm to the natural
enemies of Motschulsky tent caterpillar.
