摘    要:组建了韭菜迟眼蕈蚊Bradysia odoriphaga 在15℃、20℃、25℃和30℃温度下的实验种群生命表。结果表明,韭菜迟眼蕈蚊各虫态的发育速率随温度的升高而加快,在15℃下卵-成虫的发育历期最长(72.4天),而30℃时仅为21.2天,20℃和25℃时分别为27.3天和23.9天;韭菜迟眼蕈蚊卵、幼虫,蛹和卵-成虫的发育起点温度分别为5.9℃、8.7℃,3.3℃和7.8℃,有效积温分别为77.7、267.2、75.7和418.2日·度;韭菜迟眼蕈蚊成虫寿命随温度升高而逐渐缩短,雌虫寿命在20℃时最长,为11.7天,在30℃下最短,仅存活4.1天,除30℃外在其它温度下雌蚊寿命均长于雄蚊;单雌产卵量在20℃时最高,平均为159.9粒,30℃时最低,为114.7粒。20℃~25℃是韭菜迟眼蕈蚊的最适生长温度,成虫寿命长、繁殖力强、种群趋势指数大,温度过高或过低均不利于种群的繁衍。

关 键 词:韭菜迟眼蕈蚊    实验种群    温度    生命表

Abstract:Life tables of laboratory population of the Chinese chive maggot, Bradysia odoriphaga were constructed at four temperatures. The results showed that the developmental rate increased with the temperature increasing from 15℃ to 30℃. The longest duration of the generation was 72.4 days observed at 15℃, the shortest was 21.2 days at 30℃, and in between 27.3 days and 23.9 days at 20℃ and 25℃ respectively. The threshold temperatures and the effective accumulated temperatures required for egg, larva, pupa and wholegeneration were 5.9℃, 8.7℃, 3.3℃, 7.8℃ and 77.7, 267.2, 75.7, 418.2 degree-day respectively. The lifespan was shortened with the temperature increasing. The longest lifespan of female was 11.7 days at 20℃, and the shortest was 4.1 days at 30℃. In general, the adult longevity of female was longer than that of male. The maximum number of eggs laid per female was 159.9 at 20℃, while the least was 114.7 at 30℃. It could be concluded from the results that temperature had great effect on the development of B. odoriphaga. The most suitable temperature range was 20℃ to 25℃, during which there were longer longevity of the adult,higher oviposition and the highest population trend index. Too high or too low temperatures would be adverse to the establishment of the maggot population.
Keywords:Bradysia odoriphaga  laboratory population  temperature  life table
