Background

Prodenia litura (L.) DCSpodoptera litura (Fabriius) belonging to Lepidoptera, noctidae, the name Heliothis armigera, commonly known as Heliothis armigera.

The prodenia litura nuclear polyhedrosis virus (SpltNPV) belongs to baculovirus, is an important pathogenic microorganism of prodenia litura, has good control effect on the population of the prodenia litura, and is safe and pollution-free. The SpltNPV is produced mainly by living breeding by using prodenia litura larvae. Thus, the large-scale breeding of indoor populations of prodenia litura is a key factor in determining the yield, quality and cost of SpltNPV.

The prodenia litura is completed in one generation and needs to go through four stages of eggs, larvae, pupae and adults, and the feeding in each stage has different requirements on a feeding device. Currently, the device for raising prodenia litura indoors generally comprises an insect raising box and a eclosion chamber. The feeding method comprises the following steps: feeding 1-4-year-old larvae in a small insect-raising box; after 4 years, the larger insect-raising box is replaced to continue raising, and as the feed amount of the larvae is greatly increased and the excrement is increased, the excrement in the insect-raising box needs to be cleaned regularly; when mature larvae are reached, the larvae to be pupated are transferred into a box filled with sand for pupation; after pupation, the pupa is picked out and then transferred to an eclosion spawning device to finish eclosion spawning.
