【摘要】 通过毒死蜱、硅白灵和白蚁灵等白蚁防治新药剂对白蚁的毒力测定及野外土壤处理试验等 ,研究这几种药剂对白蚁的药效。结果表明 ,试验药剂对白蚁均具有较好的毒杀作用 ,经药剂处理过的土壤对白蚁有明显的防治效果。经质量分数为 5 0～ 2 0 0g·kg-1毒死蜱处理过的土壤在暴露及防淋避光条件下均有明显的防治白蚁效果 ,其持效期在 6a以上 ;经质量分数为 0 31 2 5～ 2 50 0 0g·kg-1白蚁灵处理过的土壤对白蚁的防治效果与质量分数呈正相关 ,其中质量分数 2 50 0 0g·kg-1的白蚁灵的防治效果至少可达 7a以上。表 5参 8更多还原

【Abstract】 Effects of new pesticides (Dursban,Silonen and Sumialfa) on termite control were made through toxicity test and field soil treatment test.The result showed that these pesticides all had good contact poisoning effects to termite.In exposition on rain and light proof,the treatments by 5 0～20 0 g·kg -1 Dursban and 2 500 0 g·kg -1 Sumialfa had a period of validity for more than six years and more than seven years respectively.Pesticide effect was positively related to the Sumialfa concentrations in 0 312 5～2 500 0 g·kg -1 .更多还原
