1.地下白蚁防治的现状地下白蚁穿越土壤表层四处觅食,其通道形成互相连接的隧道网络,并且能出其不意地进行攻击,对建筑物和含纤维素产品造成严重的经济损失。过去50年,一直运用杀白蚁剂进行土壤屏障处理来控制建后地下白蚁。第一类登记用于杀白蚁的杀虫剂是环戊二烯类有机氯杀虫剂,在美国于20世纪80年代中期因为其潜在的环境和人类健康问题被逐步淘汰。第二类
1. Status of underground termite control Underground termites feed around the surface of the soil and their channels form interconnected tunnel networks that can attack unintentionally, causing serious economic losses to buildings and cellulose-containing products.
