木材是白蚁危害的对象,土壤是白蚁主要扩散根源,本项研究作为新建房屋防治白蚁的综合措施之一。目前美国,日本很重视此项工作,对新建房屋基础附近的土壤,通常应用毒死蜱或氯丹构成一个毒土带,但这一措施费工,并且杀虫剂在土壤内受自然条件影响会缩短残效期。我国各地新建房屋的白蚁访治工作刚刚开始,大部分地区因没有立法保障,也没有通用的防治规范,所以未普遍开展此项工作。本项研究为开展新建房屋白蚁预防,进而为编制适合我国国情的白蚁预防规范做一点工作。药剂:80％乳油二氯苯醚菊,50％乳剂氯丹,稀释剂纯二甲苯,1:3水泥砂浆砌墙灰。试验采用黄胸散白蚁,采自天津市河北区三义堂胡同白蚁危害地区。经本所饲养室进行适应性饲
Wood is the object of termite damage, and soil is the main source of diffusion of termites. This study is one of the comprehensive measures for the control of termites in new houses. At present, the United States and Japan attach great importance to this work. Usually, the use of chlorpyrifos or chlordane to form a toxic soil zone on the soil near the foundation of newly built housing, but this measure is costly and the insecticide will be affected by the natural conditions in the soil. Residual period. The termite visits and visits to new houses throughout the country have just begun. In most areas, there are no legislative guarantees and there is no universal prevention and treatment standard, so this work has not been generally carried out. This study will do some work for the prevention of new termites in houses and the preparation of termite prevention regulations that suit China’s national conditions. Pharmaceutics: 80% Emulsifiable Chlorinated Chrysanthemum, 50% Emulsion Chlordane, Diluted Pure Xylene, 1:3 Cement Mortar Masonry Wall Ash. The test was conducted using yellow-breasted termites collected from the Sanyitang Hutong termite-damaging area in Hebei District, Tianjin. Adaptable feeding through our breeding room
