报告了南非共和国纳塔尔省Kwazulu北部地区的实验小屋喷洒DDT后对阿拉伯按蚊吸血与栖息习性的影响。选用了三种类型的实验小屋:1.墙壁曾喷洒过DDT,以后已经过粉刷;2.新近喷洒DDT;13.未经DDT处理,作为对照。采用两种捕蚊方法考核效果:1.用出口窗阱捕捉飞离小屋的蚊虫;2.用4％的除虫菊酯石蜡溶液喷雾后收集栖息于室内的蚊虫。结果表明,曾喷洒DDT后又经粉刷的实验小屋,室内栖息的蚊虫数与对照小屋相比无明显差异,两者分别平均为2.9只/小屋和3.7只/小屋。而新近喷洒DDT的小屋内栖息的蚊虫数则明显较低,平均0.1只/
Reported on the effects of DDT on blood-sucking and habitat of Anopheles stephensi in experimental huts in northern Kwazulu, Natal, Republic of South Africa. Three types of experimental cabins were selected: 1. The walls had been sprayed with DDT and later had been painted; 2. Newly sprayed with DDT; 13. Without DDT treatment as a control. Two methods of harvesting were used to assess the effect: 1. The export window trap was used to capture the mosquitoes that flew off the lodge; 2. The mosquitoes were collected indoors after spraying with a 4% pyrethroid paraffin solution. The results showed that there was no significant difference between the number of mosquitoes inhabiting in experimental stucco that had been sprayed with DDT after painting and the control cabin, the average of which was 2.9 / hut and 3.7 / hut respectively. However, the number of mosquitoes habitat in DDT newly sprayed cabins was significantly lower, with an average of 0.1 /
