广州地处亚热带,常年气候温湿,适宜病媒昆虫孳生繁殖,在广州旅客列车中尤以德国蜚蠊(以下简称德蠊,俗称蟑螂)为最多。我站在1973年对旅客列车中德蠊习性初步调查基础上,对德蠊的生活习性和活动规律作了进一步调查,为旅客列车中的蜚蠊防制工作,提供参考资料。 Guangzhou is located in the subtropical, warm and humid year-round climate, suitable for vector breeding insects, especially in Guangzhou passenger trains cockroach (hereinafter referred to as cockroaches, commonly known as cockroaches) as the most. Based on a preliminary survey of cockroach habits in passenger trains in 1973, I made further investigations on the habits and activities of cockroaches and provided reference materials for cockroach control in passenger trains.
