After the ground beetles emerge from nymphs into adults, they enter the reproductive stage. Egg laying begins about 10 days after mating. During the spawning period, due to its high nutrient consumption, the management at this time should be as follows:

(1) Feeding should be sufficient and a certain proportion of green feed should be given.

(2) The humidity of the raising soil should be slightly higher to prevent the large ones from eating each other and the small ones from killing each other due to the dryness of the raising soil.
