中华草蛉是粮食、棉花、果树、蔬菜等作物上多种害虫的天敌。目前许多单位已开始人工饲养,并在多种作物上进行防治害虫的试验。利用低温条件贮藏草蛉的茧和卵可以延迟成虫的羽化和卵的孵化时间,积累大量的草蛉,供适时繁殖和田间利用。为了明确不同低温对中华草蛉茧和卵的影响,找出合适的贮藏温度,进行了低温贮藏试验,本文报导1978试验的一些结果。 Chinese weed is food, cotton, fruit trees, vegetables and other crops on the pests of natural enemies. At present, many units have started artificial rearing and testing of pests on various crops. The use of cryogenic conditions to store the cocoons and eggs of larvae can delay the emergence of adults and egg hatching time, accumulate a large number of grass larvae for timely breeding and field use. In order to clarify the effect of different hypothermia on C. sinensis cocoon and egg, to find the suitable storage temperature and to carry out the low temperature storage test, some results of 1978 test are reported in this paper.
