低温贮藏赤眼蜂蜂卡是生产赤眼蜂的必备条件。为了摸索土法贮存蜂卡的方法,以利群众性的繁蜂工作,近两年来,我们进行了防空洞贮藏蜂卡的试验,取得了良好效果,已应用于生产。我所供试验的防空洞是普通战备防空洞,洞长25米、宽1米,最深处离地面4米,洞内日平均温度4月下旬为13—14℃,比室温低4—5℃,5月份为14—15℃,比室温低5—6℃;六 Trichosanthes is the prerequisite for the production of Trichogramma. In order to explore the method of storing the bee card with the native law and working with the bee masses of the masses, in the recent two years, we carried out the experiment of storing shelves in air-raid shelters and achieved good results and has been applied to the production. The air-raid shelter that I provided for testing was an ordinary combat readiness shelter with a hole of 25 meters in length and 1 meter in width. The deepest point was 4 meters above the ground. The average daily temperature in the cave was 13-14 ° C in late April, 4-5 ° C lower than room temperature and 5 Month is 14-15 ℃, 5-6 ℃ lower than room temperature;
