Embodiment 1

[0017] Construction of the rearing unit: eg figure 1 As shown, the pine weevil larva rearing device described in the present embodiment comprises an insect culture room 1, the insect culture room 1 is a PVC opaque plastic bucket with a cover 6, a flat auxiliary moisturizing layer 5 at the bottom of the bucket, and the insect culture room 1 Several circular ventilation holes 2 are opened on the wall, and the aperture of the ventilation holes 2 is 1mm. Preferably, the diameter of the insect breeding room 1 is 250mm, and the height is 400mm.

[0018] The moisture-retaining layer 5 is made of a material with strong water absorption, which can provide moisture for the pine section 2, and keep the pine section 2 fresh for a long time, which can be used for the larvae of P. xiaoshii to feed on. Preferably, the moisturizing layer 5 includes a degreased cotton layer, a cotton cloth layer and a sponge layer arranged in sequence from top to bottom. The setting of the sponge layer is to ...

Abstract

The invention discloses a breeding device for Hylobitelus xiaoi Zhang larvae. The breeding device comprises a larva breeding chamber with an inner containing space, a pine segment arranged in the larva breeding chamber and a moisturizing layer arranged at the inner bottom of the larva breeding chamber and located on the lower portion of the pine segment in an underlying mode. Multiple ventilation holes are formed in the outer wall of the larva breeding chamber, a circle of small holes are formed in the middle of the pine segment, and horn-shaped larva containing paper with an upward opening is arranged on the portion, corresponding to the small holes, of the outer side wall of the pine segment. The breeding device can be applied to breeding the Hylobitelus xiaoi Zhang larvae for a long time, can guarantee a high survival rate and a high pupation rate and has the advantages of being simple in structure, easy to clean, capable of achieving a cyclic action and the like.

Description

technical field [0001] The invention relates to the technical field of insect rearing, in particular to a rearing device for pine weevil larvae. Background technique [0002] Pinus xiaoshii is a major borer forest pest that harms pine plants such as slash pine, loblolly pine, and masson pine. Pinus slasheria is a highly concealed pest. Its eggs, larvae, pupae and some overwintering adults live in the bark and spread rapidly. It is particularly harmful to slash pine and has become the number one forest. Pests are listed as national key control targets. The larvae invade the base of the trunk or the root neck to damage the phloem tissue, seriously cutting off the transportation of organic nutrients, resulting in the death of the tree, and causing a large amount of slash pine to shed resin, thereby reducing the production of turpentine. Because the larvae of P. xiaoi are borer pests, the effect of chemical control is poor, and it pollutes the environment. Biological control w...
