确保“211工程”的卫生指标实施，主要的化学防治技术措施：1．选择有效的杀虫剂。采用持效期长（加高效氯氰菊酯，触杀作用强，一个月，死亡率仍为100％）和速效性好（15～20分钟，击倒、死亡率100％）的两种类型拟除虫菊酯；2．设计安全性可靠的程序施药。如浓度、用量和施药方式等。调查结果表明学生宿舍（1200个房间），基本上无蚊、无蝇、无蟑螂，防治效果显著，获得“211工程”初审的认可，并且本次还为学校节省费用24530元。
Ensure “211 Project” health indicators implementation, the main chemical control measures: 1. Choose an effective pesticide. The two types of pyrethroids with long-lasting effect (cypermethrin, strong contact effect, 100% mortality rate in one month) and good quick-effect (15-20 minutes, knockdown and 100% mortality rate) 2. Design safe, reliable procedures for application. Such as concentration, dosage and application methods. The survey results showed that the student dormitory (1200 rooms) was basically free of mosquitoes, no flies and no cockroaches, and the prevention and control effect was remarkable. It was approved by the first instance of “211 Project” and saved 24,530 yuan for this school.
