白纹伊蚊是我国常见蚊种之一,传播登革热及乙型脑炎等疾病。由于该蚊在我国地理分布面广,为了解不同地理株白纹伊蚊某些生态学和生物学的特点,对全国10个不同地理株进行杂交、自育性、幼虫期发育速度及蛋白电泳带的实验观察,作为今后进一步研究媒介宿主与病源体的关系以及探索防制方法的基础。这10个地理株来自北京、郑州。合肥、上海、成都、武汉、南昌、广州、南宁和湛江。对上述10个地理株的标本进行形态鉴定,均为白纹伊蚊(Aedes albopictus)。各地理株的白纹伊蚊均饲养在同一实验条件下,维持温度在28±0.5℃,相对湿度90％左右,光周期每天光照12小时。幼虫每100条饲养在200毫升容量的瓷碗,每天(食畏)饲3:7的兔肝和酵母粉、成虫按实验需要给予10％葡萄糖液或兔血。
Aedes albopictus is one of the common mosquito species in China, spreading dengue fever and Japanese encephalitis and other diseases. As the mosquito is widely distributed in our country, in order to understand some ecological and biological characteristics of Aedes albopictus in different geographical strains, 10 different geographic strains were crossed, self-fertilized, larval development and protein electrophoresis With the experimental observation, as the future further study of the relationship between the host and the pathogen host and to explore the basis for prevention and control methods. The 10 geographical strains from Beijing, Zhengzhou. Hefei, Shanghai, Chengdu, Wuhan, Nanchang, Guangzhou, Nanning and Zhanjiang. Specimens of the above 10 geographic strains were morphologically identified as Aedes albopictus. All geographical strains of Aedes albopictus were kept under the same experimental conditions, maintaining the temperature at 28 ± 0.5 ℃, relative humidity of about 90%, photoperiod 12 hours a day light. The larvae were kept in 200 ml capacity porcelain bowls for every 100 animals. 3: 7 rabbit liver and yeast powder were fed daily (Intrepid) and 10% glucose solution or rabbit blood was given to adults according to the experiment.
