白纹伊蚊飞翔能力和扩散距离观察

Investigation on the Hover Ability and Spread Range of Aedes albopictus

目的：观察和测定白纹伊蚊的飞翔能力和扩散距离。方法：在自然条件下，设立观察点，定期监测白纹伊蚊及当地气象因素和环境因素。结果：该蚊的飞翔能力较弱，一般为５０～１００ｍ，最大飞翔距离约为４００ｍ，成蚊的飞迁扩散活动与其产卵习性及幼虫密度显著相关，气象因素及环境因素对该蚊的飞迁活动有显著的影响。结论：这对研究和控制白纹伊蚊传播登革热。

The hover ability and spread range of Aedes albopictus was observed and surveyed in natural environment.The result showed that,the hover ability was weak,it was about 50～100m range,the longest distance of spread was about 400m.The adult mosquitoes spread have marked relationship with the habit of its oviposit and density of larvae.The marked relationships between hover ability,spread range and weather factors,environment factors were discussed in the paper,as well.The studies are of importance for controlling dengue fever.
