The comprehensive control technology mainly based on natural enemy insect dastarcus helophoroides is utilized to successfully solve the problem of serious diseases and insect pests seriously harming the forest health of China, wherein the serious diseases and insect pests comprise anoplophora glabripennis harming the 'three-north' protection forest, monochamus alternatus hope spreading the pine wood nematode disease, monochamus castaneus harming the natural broad-leaved forest mainly based on oak trees and the like.
At present, three methods for breeding dastarcus helophoroides are summarized. The method comprises the steps of collecting the egg cards of the dastarcus helophoroides for artificial inoculation, sequentially inoculating the larvae of the dastarcus helophoroides which are hatched at the abdominal nodes of breeding hosts by using a writing brush after the eggs are hatched, placing the breeding hosts with the larvae of the dastarcus helophoroides in a transparent finger-shaped tube, plugging the tube orifice by using a cotton ball, filling the breeding hosts in a plastic feeding box, and culturing under proper conditions. An artificial feed, which is specifically disclosed in Chinese patent applications with application numbers of CN201610321127.2 and CN201210474799.9, is used for feeding dastarcus helophoroides larvae according to nutritional ingredients required by the development of the dastarcus helophoroides larvae. One is equipment assistance, which is specifically referred to as Chinese patent application with application number of CN201410367163.3, the dastarcus helophoroides breeding box consists of a box body, an egg carrying plate and a box cover, and the color is black; the inner part of the breeding box is in a grid shape, and the egg carrying plate is arranged above the grid in the box; the egg carrying plate is provided with a small hole; the box cover is provided with air holes. Barley pest or yellow meal worm pupae are placed in the grid of the breeding box, the egg carrying plate with the dastarcus helophoroides egg cards is placed on the grid, and the lid of the breeding box is covered.

Wherein, the breeding tube (figure 1) comprises a tube body 1, and a fixing ring 2 is arranged on the outer side of the top of the tube body; the upper part of the tube body is in an oblate column shape, and other suitable shapes can be selected at the upper part; the lower part of the tube body is in an inverted quadrangular pyramid shape, the hollow part is connected with the tube body and the base 4 through four support columns 3, of course, the lower part of the tube body can be in other support shapes such as circular, and the number of the support can be 3-8 according to the distance between the support bodies. The breeding tube is designed and manufactured according to the shape and the size of the breeding host, so that the breeding host cannot move freely in the tube body, and meanwhile, the host cannot be extruded and damaged; the top of the tube body is fixed to keep the tube body stable in the breeding box; the hollowed-out part between the lower part of the breeding pipe and the base is convenient for the larvae of dastarcus helophoroides to directly search the hosts and complete parasitism through the hollowed-out part, and meanwhile, the aged larvae of dastarcus helophoroides can also migrate to the bottom cover of the box from the hollowed-out part at the lower part of the breeding pipe to pupate, so that the imagoes of dastarcus helophoroides can be conveniently collected.
According to the structural design of the body shape of the breeding host, the activity space of the breeding host can be well limited when the breeding host is arranged in the breeding tube, and the phenomenon that the parasitic rate is low because the larvae of the dastarcus helophoroides fall off from the host due to the resistance of the host to the parasitic behavior (twisting of the polypide) is avoided; on the premise of ensuring that the movement of the host can be limited, the hollow structure is added on the breeding pipe device to increase the searching probability of the dastarcus helophoroides to the host. The grids in the box body of the breeding box are suitable for the size of a single breeding pipe, so that the larvae of the dastarcus helophoroides can independently search hosts in a closed space and complete parasitism.
The breeding box (figure 2) is composed of a box top cover 5, a box body 6, a partition plate 7 and a box bottom cover 9, air holes 8 are uniformly distributed on the periphery of the box body, the aperture size of each air hole does not allow the dastarcus helophoroides larvae to pass through, the air holes 8 are uniformly formed on the periphery of the box body 6, and the whole box body is opaque and white in color. The box top cover 5 is convenient for placing the breeding tube in the box top cover, and the air holes on the box body 6 ensure the air permeability of the device; the grid formed by the partition plate 7 can be replaced according to the size of the breeding pipe, in addition, the breeding pipe can be kept stable in the grid, and the space in the box body can be utilized to the maximum extent; the box bottom cover 9 provides convenience for collecting the dastarcus helophoroides adults and cleaning the box body; the box top cover 5 and the box bottom cover 9 are the same in size and can be mutually used, and the use efficiency is improved. The breeding tube is used independently, and certain effect of the invention can be achieved; as long as the free movement of the host can be limited, the breeding efficiency of the dastarcus helophoroides can be improved to a certain degree. The invention limits the idea of host activity and can be used for breeding various natural enemy insects.
The combination of the breeding tube and the box body (figure 3) can obviously improve the parasitic rate and the breeding rate of the dastarcus helophoroides to the host, realize the autonomous search and the parasitic of the dastarcus helophoroides larva in the box body and the host in the breeding tube, and simultaneously facilitate the collection of the dastarcus helophoroides imagoes. Breed the pipe in figure 3 and place the cutting grid in division board 7, through breeding 2 joints of solid fixed ring of pipe in the grid top that division board 7 formed, the length that solid fixed ring stretches out the pipe body is unsuitable too long, avoids the interference between the adjacent solid fixed ring. After the breeding is completed, the user can extract the whole breeding tube from the separation grid by extracting the fixing ring 2. Can set up on division board 7 with solid fixed ring 2 matched with concave station structure, realize breeding the pipe joint fixedly through this concave station structure and solid fixed ring 2 cooperation. The device effectively solves the problems of low parasitic rate, poor breeding effect, difficult collection of imagoes, high breeding cost and the like of the dastarcus helophoroides, and is suitable for mass production and application of the dastarcus helophoroides.
