摘要
１９９０～１９９３年，应用２０％三唑磷乳油进行防治马尾松毛虫和鞭角华扁叶蜂幼虫试验，结果如下：①采用３００～１６００倍液防治第１代≤３龄马尾松毛虫幼虫，７２ｈ后，其杀虫率为９０．４％～１００％，防治≥４龄幼虫的，其杀虫率为８９．１％～９５．８％；防治第２代≤３龄幼虫，７２ｈ后，其死亡率为７１．９％～９０．７％．②采用５００～２０００倍液防治鞭角形扁叶蜂幼虫，并与同倍数的４０％水胺硫磷、５０％甲胺磷进行对比，使用三唑磷的，７２ｈ后，其死亡率力４０．３％～９９．２％，９６ｈ后残毒药效为１４．２％～１００％，优于甲胺磷，次于水胺硫磷．在本试验设计浓度范围内，它们的杀虫效果（包括残毒药效）都是随浓度加大而随之提高．
From 1990 to 1993, experiment of effect of triazophos on larva of Dendrolimus punctatus and Chinolyda flagellicornis showed;1. to control≤3 instar and≥4 instar of the first D. punctatus generation with 300-1600 fold solution, the mortality after 72 hours was respectively 90. 4%～100% and 89. 1%～95. 8%;to control≤3 instar of the second generation, the mortality after 72 hours was 71. 9%～90.7%. 2. to control Ch. flagellicornis with 500～2000 fold solution and compared with the same fold solution of 40% iscarbophos, 50% methamidophos,the mortality after 72 hours control with triazophos aam 40.3%～99.2%, the residual toxicity after 96 hours was 14. 2%～100% which was better than methamidophos, but worse than isocarbophos.
