preparation example Construction

[0061] Preparation of substitute hosts: Put 2 substitute hosts into the groove in the middle of the insect-raising wooden block, put kraft paper with a length and width of 80×30mm on top of the groove, and then put a glass carrier with a length, width and thickness of 75×25×2mm Then wrap it with a rubber band to fix it, and put it in a plastic insect cage. Put 4 such wood blocks for raising insects in a plastic box, then insert 25 females of Scleroderma sichuanensis or Scleroderma guanii, cover the box cover (there is no ventilation hole on the cover), and in 20~ After 24 hours, check whether the surrogate host in the vermin block has been anesthetized by the swollen-legged wasp sting. Take out the anesthetized surrogate host and put it into a petri dish with a lid whose diameter and height are 65mm and 25mm respectively, and then replace it with a new surrogate host. The petri dish of the host is stored at a low temperature of 3-5°C for later use.

specific Embodiment

[0064] Concrete embodiment, the artificial large-scale raising, propagation and release of the piebald velvet carapace:

[0065] 1. Breeding:

[0066] Refers to conventional and conservation breeding. Make an insect-raising box first, that is, in a plastic box with a cover (length x width x height = 17.5 x 11.5 x 6cm), lay a layer of white plastic window screen (mesh is 2 x 2mm) with the same size as the bottom of the box. ), then put in an insect-raising wooden block (length×width×height=8.4×4.5×3.5cm), a rest paper bag for adults, a drinking fountain, and a feeding dish to make an insect-raising box, and then put the variegated flower 30 velvet beetle adults, covered with a plastic box cover (there are 5 ventilation holes with a diameter of 1-2mm); clean the sanitation in the insect rearing box once every two days, change the feed, add distilled water, and place it at a temperature and humidity of 20 ℃±2℃ and 60%±5% environment.

Abstract

The invention discloses a captive-breed piebald dastarcus helophoroides and a technology applied to prevent and control monochamus alternatus hope; the technology has the following steps: first, feeding imagoes of the piebald dastarcus helophoroides in the environment with the environmental temperature ranging from 23 DEG C to 27 DEG C and humidity ranging from 55 DEG C to 65 DEG C and inducing the imagoes to oviposit in large quantity and incubate larvae of the piebald dastarcus helophoroides; then using an alterative host to facilitate the larvae to live a parasitic life and grow, thus finally eclose to imagoes; then preparing the ovum or imagoes of the piebald dastarcus helophoroides into ovum release cards or imago release bags or finger-shaped tubes to be released in forest stands endangered by monochamus alternatus hope in the bursaphelenchus xylophilus disease area. With natural enemy insects adopted to control pests, the pests and the disease can be brought under effective andsustained control in the premise of not polluting the environment, maintaining ecological balance and biodiversity, therefore, the technology of the invention is an advanced technology for controlling monochamus alternatus hope and bursaphelenchus xylophilus disease.

Description

technical field [0001] The invention relates to a biological control technology, in particular to a technology for artificially propagating the variegated velvet beetle and its application to the control of the monochamus alternatus. Background technique [0002] Monochamus alternatus Hope, also known as Monochamus alternatus Hope, belongs to Coleoptera (Coleoptera) subfamily Laminae, and is harmful to pine trees (Pinus spp.), especially Masson pine (P.massoniana ) important borer pests. During the nutrition supplement period, the adult pine beetle gnaws on the young shoots and bark of pine trees, while the larvae eat into the trunk to damage the cambium and xylem, cut off the tree's conducting tissue, cause the host tree to weaken, and in severe cases cause the tree to lose its vigor. die. In addition to directly harming trees, the pine beetle is more importantly capable of carrying and spreading pine wilt disease (also known as pine wilt disease). [0003] The pathogen ...
