Problems solved by technology

However, due to the difficulty in obtaining high-quality reproductive hosts, the industrialization of Scleroderma guanii in China has been seriously hindered.
Longhorn beetle is an excellent breeding host for the reproduction of Scleroderma guanii, but the existing methods of artificially raising longhorn beetle all have the defect of low survival rate

Abstract

The invention relates to feed for artificially feeding trichoferus campestris larvae. The feed is prepared by the following raw materials in percent by weight: 5-10% of willow bark powder, 10-15% of willow xylem powder, 3-10% of fly maggot powder, 3-10% of sugar, 3-7% of agar, 0.1-1% of Vc, 0.1-1% of a preservative and 50-70% of water. The invention further provides a method for artificially feeding the trichoferus campestris larvae by the feed. By adopting the feed and the method, the problem of artificial feeding of trichoferus campestris from early larvae to last instar larvae is successfully solved, the survival rate of the trichoferus campestris is greatly increased, and the main technical problem of the trichoferus campestris in an indoor expanding propagation process is solved.

Description

technical field [0001] The invention relates to the field of beetle breeding, in particular to a feed for artificially raising long beetle larvae and an application thereof. Background technique [0002] The use of natural enemy insects to control pests can effectively and continuously control pests and diseases without polluting the environment, maintaining ecological balance and maintaining biodiversity. Scleroderma guanidei is an ectoparasitoid of the larvae and pupae of various borer-boring pests, such as the rough-sheathed bispinous longhorn beetle, Cyperus chinensis, and poplaria, and is the main natural enemy of the above-mentioned borer-boring pests. However, due to the difficulty in obtaining high-quality reproductive hosts, the industrialization of Scleroderma guanii in China has been seriously hindered. Longhorn beetle is an excellent breeding host for the reproduction of Scleroderma guanii, but the existing methods of artificially raising longhorn beetle all hav...
