生产车间的蟑螂侵害率及防制措施研究

本文对上海市区35个生产车间的蟑螂侵害率进行调查,观察到生产性车间有黑胸大蠊及美洲大蠊两种,侵害率达58.85%。在20个有蟑螂的车间内都有黑胸大蠊栖息,平均密度10.65只/m~2;而美洲大蠊仅见于8个车间,聚集性较强,平均密度达38.50只/m~2。对较干燥车间或地下室用1%乙酰甲胺磷糖水毒杀蟑螂,24h杀灭率达95.89%。

Studies on the Infest Rate and Control of Cockroach in the Productive Workshops

The paper reported the result that studies on the infest rate and control of cockroach in 35 productive workshops in Shanghai. Two species of cockroach, Periplaneta emarginata and P. americana are discovered in the productive workshops. The result showed that the infest rate of cockroach were 58.85%. An average density of P. emarginata per square meter was 10.65 in 20 workshop, but P. americana was 38.50 only in 8 workshops. On the spot used 1% Ac(?)phate sugar liquid asan insecticide against cockroach were carried in the dry wokshops or basement, the average pesticidal rate was 95.89% for 24 hours after.
