摘要: 目的了解白纹伊蚊和埃及伊蚊的种间关系。方法在温度25~28℃、RH65%~80%、光周期(L∶D)12∶12的实验条件下,将两种伊蚊Ⅳ龄幼虫各100条混合饲养(亲代P0),用电动吸蚊器吸取各代成蚊约1000只进行分类观察。结果在各代中,白纹伊蚊的种群数量大于埃及伊蚊,且随着传代次数的增加而增大,到子2代(P2)时,该混合群落中已经观察不到埃及伊蚊。结论白纹伊蚊和埃及伊蚊存在着激烈的种间竞争关系,并以白纹伊蚊优胜。

Abstract: Objective To study the Interspecific relationship between Aedes albopictus and Aedes albopictus.Methods To culture the two mixed species of 100 4-star larva respectively(F0) in the temperature 25- 28 ℃,RH 65%- 80%,and photoperiod(L∶D) 12∶12 condition,then to observe about 1 000 imago collected by electric mosquito collector at different time.Results The population of Aedes albopictus was larger than Aedes albopictus in every generation,and larger with increasing of generation.In second filial generation(P2),there was no Aedes aegypti being observed in the mixed population.Conclusion Severe interspecific competition was founded in the experiment,and Aedes albopictus is more competitive in the laboratory.
