爱维菌素Avermectins是泥土放线菌Streptomyces avermitilis分离出的一种新化合物,在低剂量下对多种节肢动物有很高毒效。给予脊椎动物适当剂量可以使吸血的节肢动物死亡。对蜱和采采蝇的作用已进行了一些实验,但对蚊虫的防制效果尚无报道。本文报导爱维菌素二种化合物MK-933和MK-936对斯氏按蚊、埃及伊蚊、尖音库蚊和致倦库蚊的实验结果。实验一、在300ml玻璃烧杯内分别盛用自来水配制的200ml二种爱维菌素药液
Avermectins is a new compound isolated from soil actinomycetes Streptomyces avermitilis and has high toxicity to many kinds of arthropods at low doses. Appropriate doses given to vertebrates can kill vampire-bearing arthropods. Some experiments have been conducted on the effects of ticks and tsetse flies, but the control effect on mosquitoes has not been reported yet. This article reports the experimental results of the two compounds Avermectins MK-933 and MK-936 on Anopheles stephensi, Aedes aegypti, Culex pipiens pallens and Culex quinquefasciatus. Experiment A, respectively, in a 300ml glass beaker with tap water formulated 200ml two kinds of love avermectin liquid
