目的探明夜间不同时间中华按蚊的经产蚊比率的变化规律。方法在中华按蚊密度较高的泗港农村猪舍于7～8月在19:00至次晨5:00,每小时捕捉猪舍内的中华按蚊,第二天解剖,判断经产蚊,计数夜间每小时中华按蚊的经产蚊比率。结果 19:00～20:00段中华按蚊经产蚊比率最低,之后逐步增加,22:00以后持续维持在一定的水平。结论夜间中华按蚊经产蚊比率呈现出傍晚低、深夜及下半夜高。
Objective To investigate the variation of mosquito breeding rate of Anopheles sinensis at different times at night. Methods Anopheles sinensis in the pigs house was collected every hour from 19:00 to 5:00 am in July and August in the sowing village with high densities of Anopheles sinensis. The next day, , Count the mosquito production rate of Anopheles sinensis per hour at night. Results Anopheles sinensis had the lowest mosquito production ratio from 19:00 to 20:00, and then gradually increased. After 22:00, it maintained at a certain level.
