白纹伊蚊在我国分布很广,遍布全国25个省,是登革热的传播媒介。目前预防或控制登革热的发生和流行的根本措施是控制和消除蚊幼孳生。为此,我们于1980年5～10月配制了双硫磷木块吸附型缓释剂,在室内和现场观察其对白纹伊蚊的毒杀效果,并对影响毒效的某些因素作了探讨。一、材料与方法(一)室内试验1.缓释剂的配制:载体有杉木块、松木块、软木块(用水松软木塞切成)、杂(硬)木块4种,大小均为2×1×1厘米。供试药物系江苏南通农药厂1978年生产的80%双硫磷原油(上海昆虫研究所提
Aedes albopictus widely distributed in our country, all over the country 25 provinces, Dengue fever is the media. At present, the fundamental measure to prevent or control the occurrence and prevalence of dengue fever is to control and eliminate mosquito breeding. For this reason, we formulated the release-inhibiting agent of the parathion blockade from May to October in 1980 and observed the poisoning effect against Aedes albopictus both indoors and in the field, Discussion. Materials and methods (a) laboratory tests 1. Preparation of sustained-release agents: carrier fir blocks, pine blocks, cork blocks (cut with cork cork), miscellaneous (hard) × 1 × 1 cm. Test drug for Jiangsu Nantong Pesticide Factory produced 80% of diphosphine crude oil in 1978 (Shanghai Institute of Entomology
