Technical method for raising ground beetles (Eupolyphaga sinensis) with cottonseed hulls

If there is no place for @#@255@#@, ground beetles can be raised according to the principle that cottonseed hulls ferment and generate heat. The method is simple, and is briefly introduced as follows.

In a jar 30 cm in diameter, put prepared cottonseed hulls, press them tight, and place inside a small basin 20 cm in diameter; in the small basin put a layer of loose soil with moisture suitable for the growth of small ground beetles, then put the small ground beetles into the basin, and on top put some feed for the small ground beetles to eat; then cover the mouth of the jar tightly with old cotton wadding.

Preparation method of the cottonseed hulls: generally, according to the temperature needed, add water, mix evenly and press tight, and place a pillar-type thermometer inside. If the temperature is not enough, spray some water on the cottonseed hulls; if the temperature is too high, add some dry cottonseed hulls, until the temperature is adjusted to the normal 32°C.

It must be noted that the cottonseed hulls must be pressed tight, otherwise the temperature cannot achieve a constant effect. Generally the temperature can be maintained for about 40 days, and after the cottonseed hulls have completely rotted, they should be replaced.
