韭菜迟眼蕈蚊的简易人工饲养方法

A Simple Rearing Method for Bradysia odoriphaga

本研究通过自制的饲养器具，建立了饲养韭菜迟眼蕈蚊的简易方法。将野外采集的幼虫饲养在自制装置中，（25±1）℃、相对湿度70％、光暗周期L∶D＝16∶8的条件下，用滤纸收集蛹，用葱白片收集卵。采用此法饲养的韭菜迟眼蕈蚊可顺利完成生活史，其孵化率为91．0％～94．2％，幼虫的存活率为86．4％～92．0％，化蛹率为82．0％～87．6％。本方法节省人工和饲养空间，可有效实现韭菜迟眼蕈蚊的人工批量繁殖。本方法能广泛应用于其它根蛆类昆虫的饲养。

A convenient method for rearing Bradysia odoriphaga （ Diptera： Sciaridae ） was conducted . The larvae collected from the field were reared in modified culture dishes .The experiment was performed in an artificial climate chamber with the air temperature of （25 ±1）℃, humidity of 70%and the light-dark cycle of 16∶8 .The pupae were collected with pieces of filter paper .The eggs were collected with welsh onion stalks .Under these conditions , Bradysia odoriphaga could complete life cycle successfully .The hatching rate of eggs was 91.0%~94.2%, the survival rate of larvae was 86.4%~92.0% and the pupation rate was 82 .0%~87 .6%.This method could save labour and rearing space and effectively achieve mass propagation of Bradysia odoriphaga.It also could be used for rearing other root maggots .
