利用四季豆饲养盲蝽的方法

A rearing method for mirids using the green bean,Phaseolus vulgaris in the laboratory

四季豆是多种盲蝽的寄主植物，该研究旨在发展一个利用四季豆豆荚规模化饲养多种盲蝽的技术。研究结果表明：绿盲蝽与中黑盲蝽的若虫最佳饲养密度约为100头／盒（2L），成虫为60～80头／盒。绿盲蝽成虫喜好在切头豆荚的两端伤口处产卵，而中黑盲蝽喜欢在完整豆荚的两端产卵。养虫盒内添加一些弯曲的纸条有助于提高若虫存活率和成虫产卵量。产卵后的豆荚需晾干后放置在25～28℃、相对湿度60％～70％、光照16：8（L：D）的环境下，以减少豆荚腐烂和提高卵的孵化率。利用这一方法饲养盲蝽的若虫存活率、成虫产卵量和卵孵化率分别达60％、40粒和80％。

The green bean, Phaseolus vulgaris is a main host plant of several important mirids, and a study was conducted for developing a rearing method to culture of mirids with fresh beanpods in the laboratory. The optimal rearing density for Apolygus lucorum and Adelphocoris suturalis was approximately 100 nymphs or 60 - 80 adults per 2 L box. A. lucorum prefers to oviposit in the wound of end-cutting beanpods, and A. suturalis likes to lay eggs in the ends of intact beanpods. Adding some curving scrips in the culture boxes can greatly benefit the nymphal survival and adult oviposition. After adult oviposition, beans with eggs need to decrease water content firstly, then place under the environment of 25 - 28℃ and 16 ： 8（L： D） with 60% -70% RH for avoiding the rot of beans and increasing egg hatching rate. Using this method, four species of mirids were successfully reared with a nymphal survival rate of 60%, egg incubation rate 80% and fecundity of 40 eggs per female.
