【摘要】 1997—2003年在浙江余杭开展白捕特微胶囊防治白蚁试验,5种药剂质量浓度(62 5,125,250,500,1000mg·kg-1)的触杀作用试验结果均达100%,最低质量浓度62 5mg·kg-13d后的死亡率也达到100%;驱避效应、木块抗蚁效果理想,只有经低质量浓度(62 5mg·kg-1)处理过的土壤,白蚁才能穿越一定距离。野外土壤处理试验,经250～1000mg·kg-1药剂质量浓度处理过的土壤对白蚁的防治效果与药液浓度呈正相关趋势,其中1000mg·kg-1浓度组,经过5a的防蚁效果仍达100%,6a后的防蚁效果达80%,同时,经风化处理后对其药效影响不明显。白捕特微胶囊对于黄胸散白蚁比家白蚁效果更好。更多还原

【Abstract】 Experiments of using Baktop capsules to control termite were made in Yuhang of Zhejiang Province from 1997 to 2003. The contact poisoning effects of 5 different dosages(62.5,125,250,500,1 000 mg·kg^-1) were all 100%,and the mortality of the least dosage,62.5 mg·kg^-1,was also 100% after 3 days. The expellable effect and the wood resistance to termite were very excellent though termite could pass through a short distance in the poisonous soil treated by the least dosage,62.5 mg·kg^-1. The results of field soil treatment test showed that control effect of the poisonous soil treated by 250～1 000 mg·kg^-1 Baktop to termite was positively correlated with the dosages of pesticide.The control effect of 1 000 mg·kg^-1 was 100% after 5 years,and 80% after 6 years.The results also showed that efflorescence had no effect on the control effect of Baktop.The control effect of Baktop capsules to Reticulitermes speratus was better than that of to Coptotermes formosanus.更多还原
