Rearing device for low-instar armyworm larvae and rearing method thereof

Abstract

The invention discloses a rearing device for low-instar armyworm larvae and also discloses a rearing method for low-instar armyworm larvae. The rearing device for the low-instar armyworm larvae comprises a seedling raising device and a larval rearing box; the seedling raising device comprises a nutrient solution tray, wherein a seedling raising tray is arranged on the nutrient solution tray, and the bottom of the seedling raising tray communicates with an inner cavity of the nutrient solution tray through a first through hole; and the larval rearing box comprises a cooperated box body and a box cover, the larval rearing box is used for placement of the seedling rasing device, and ventilation holes are arranged on the larval rearing box. The rearing device for the low-instar armyworm larvaeis simple in structure, convenient to rearing, and saves manpower and material resources.

Description

technical field [0001] The invention relates to the technical field of insect feeding, in particular to a feeding device and a feeding method for young armyworm larvae. Background technique [0002] Armyworm is a kind of agricultural pest. In recent years, the armyworm has occurred seriously every year, especially in the main corn producing areas, often causing the phenomenon of corn "stalk" and seriously affecting the yield and quality of grain. Therefore, strengthening the research on armyworm is not only beneficial to control it well, but also can use it to develop some products, so the artificial breeding of armyworm has been paid more and more attention by researchers. [0003] Armyworm is a kind of metamorphosis insect, which has four developmental stages: adult, egg, larva and pupa. Armyworm larvae have the habit of killing each other in the case of food shortage. At present, it is necessary to manually put fresh plant leaves to the larvae and plant If there are too ...

AI Technical Summary

Problems solved by technology

[0003] Armyworm is a kind of metamorphosis insect, which has four developmental stages: adult, egg, larva and pupa. Armyworm larvae have the habit of killing each other in the case of food shortage. At present, it is necessary to manually put fresh plant leaves to the larvae and plant If there are too many, the excess plant leaves will rot and deteriorate, and the nutrients cannot be guaranteed and need to be cleaned. If there are not enough plants to feed, the larvae will kill each other. Therefore, artificial breeding requires a lot of manpower and material resources. The prices of larvae, larvae and pupae have remained high in the market
