为了解低温下蚊虫孽生及其活动情况,在野外气温低于摄氏13℃的自然条件下,观察了蚊虫的孽生、羽化、飞迁和吸血等.结果:水中孽生的主要是以幼虫形式越冬的蚊种,蚊虫的羽化率较低,但仍有蚊种吸血、群舞交尾;许多蚊虫的栖息场所正是其越冬场所;与以成蚊形式越冬的蚊种相比,以卵或幼虫形式越冬的蚊种,对温度的适应范围更广泛,耐受性更强,吸血的蚊种更多.
In order to understand the living conditions of mosquitoes and their activities at low temperature, the natural habitats, feathering, migration and blood-sucking of mosquitoes were observed in the wild under the conditions of temperatures below 13 ℃ .Results: The overwintering mosquito species had lower emergence rate of mosquitoes, but there were still mosquito species blood-sucking and swarming of groups of dances. Many mosquitoes habitats were overwintering places. Compared with mosquitoes that overwintered as mosquitoes, eggs or larvae Mosquito species in the form of wintering are more widely adapted to temperature and more tolerant and more blood-sucking mosquito species.
