为寻找高效、低毒、长效灭蚊药剂,以有效地防制抗性和野栖性的媒介蚊虫,我们在1973—1974年对杀螟松毒杀按蚊的效力和抗疟效果进行了观察。并同时以二二三、六六六、马拉硫玲、杀螟睛等杀虫剂作比较试验观察。现将实验结果摘要如下。一、杀螟松滞留喷洒对几种按蚊的毒杀效果:1973年5至11月,先后在广州近郊和海南罗葵大队进行此项实验。在广州近郊,以当地原有牛房,略经参葺使之适于安装窗诱蚊器,作为实验小屋观察。据测试,当地中华按蚊对二二三产生抗性。以50%杀螟松乳油,按每平方米面积2
In order to search for efficient, low-toxic and long-acting anti-mosquito agents to effectively control resistant and wild-borne vector mosquitoes, we carried out the efficacy and anti-malarial effect of the Anopheles Sinipedatum from 1973 to 1974 Observed. And at the same time to two hundred twenty-six, six six six, Mara sulfur Ling, kill borers and other insecticides for comparative test observation. Now the experimental results are summarized as follows. First, the fenitrothion residency spray poisoning effect on several Anopheles: From May to November 1973, successively in the suburbs of Guangzhou and Hainan Lok Kwai for this experiment. In the suburbs of Guangzhou, with the original original cow houses, slightly by the Senate repair make it suitable for installation of window mosquito traps, as the experimental observation cabin. According to the test, the local Anopheles sinensis is resistant to Erzan. To 50% fenitrothion EC, according to an area of 2 square meters
