摘要
自1991年起,三二四一七部队连续3年开展灭蟑螂达标活动。在查清蟑螂虫情的基础上,坚持以环境治理为主,采用药物喷洒和药笔划线相结合的方法,蟑螂成、若虫侵害率由灭前的47.5%降至1.5%,平均密度(只/间)由灭前的21.3降至3.2;卵鞘侵害率由灭前的5.5%降为0.4%,平均密度(只/间)由灭前的2.1降至1.4.灭蟑达标后巩固至今,各项指标均维持在"双五。
The cockroach elimination activity was carried out at 32417 troops from 1991-1993. Adult and nvmph infestation rate dropped from 47.5% to 1.5% and the average density index(individal/room) dropped from 21.3 to 3.2.Ootheca infestation rate droped from 2.1 to 1.4. After control activity,all index reached the 'double five' and'double two' standards.
