【摘要】 10%吡虫啉可湿性粉剂与河沙混合成含有效成分(%)0.10、0.05、0.025、0.0125,家白蚁饲养其上,48～72h内100%死亡,浓度越高,死亡越快;白蚁也不能穿过以上述浓度配制的长10cm沙土管,对照则穿行自如;以上述浓度药液浸的杉木块,也完全防止白蚁取食,对照则严重被食.在室外(2004.5～2005.5),家白蚁不能通过含0.05%及0.10%药液淋浇(1000ml/40×50cm)的土壤,去取食试区中心的无药木块.吡虫啉可湿性粉剂不用有机溶剂,无刺激气味,运储施工方便,可以认为它是当前最高效的环保型白蚁防治药剂,并建议生产中以0.05%(10%可湿性粉剂稀释200倍)用于室内防治,0.10～0.05%(稀释100～200倍)用于室外防治.更多还原

【Abstract】 In laboratory 10 % Imidacloprid (w.p.) mixed with sand in (a.i.%) 0.10,0.05,0.025, 0.0125,termite Coptotermes formosanus live on it were killed within 48～72 h.,the higher the dosage was,the early the death was,termite can not go through these termicid-soil tube (10 cm long ),However in the clean sand tube (CK),termites go through freely.Termite can not eat the wood which soaked with 0.05,0.10 % concentration imidacloprid.In field,termites can not enter the soil treated with 0.10, 0.05 % imidacloprid dilutions (1 000 ml/40×50 cm) to damage the wood.So it is a high affective and environ-friendship termicid.We suggested using 0.05 % dilution for building,and 0.10～0.05 % for outside building.更多还原
