1983～1984年在贵州省思南县塘头地区观察了混灭威和溴氰菊酯滞留喷洒防制中华按蚊的效果.敏感性试验显示两者对当地唯一传疟媒介、对有机氯和有机磷杀虫剂有高度抗性的中华按蚊均有较高毒效。实验小屋观察表明溴氰菊酯25mg/m~2在竹席墙面的残效超过3个月,混灭威2g/m~2的相应残效为45～50d。在现场用上述剂量一年两次滞留喷洒能使中华按蚊高峰季节媒介能量分别比对照区下降91.4％和85.2％;结合其他防治措施后,疟疾发病率分别比前一个流行年度下降43％和41.2％.
1983 ~ 1984 in Tongnan area of Sinan County, Guizhou Province, we observed the effect of propoxur and deltamethrin spraying to control Anopheles sinensis.The sensitivity test showed that the two were the only malaria transmission media in our country, Organophosphorus insecticides are highly resistant to Anopheles sinensis have higher toxicity. The experimental cabin observation showed that the residual effect of deltamethrin 25mg / m ~ 2 on the bamboo mat wall was over 3 months, and the corresponding residual effect of 2mg / m ~ 2 was 45 ~ 50d. In the field with the above dose twice a year of retention spraying can make the Anopheles sinensis peak season medium energy than the control area decreased by 91.4% and 85.2%; combined with other control measures, the incidence of malaria than the previous popular year drop 43% and 41.2%.
