A composition for inducing concentrated oviposition of black soldier flies and its application method

Abstract

The invention discloses a composition for inducing concentrated oviposition of black soldier flies and its application, and belongs to the technical field of insect breeding. The composition includes an attractant odor substance arranged on an oviposition substrate, and the attractant odor substance includes methyl acrylate , lactic acid, 3-methylindole, n-heptanoic acid, dimethyl disulfide, through the combination of attractive odor substances and the color of the oviposition substrate, to attract black soldier flies to the corrugated paper Eggs are laid in the seams, so that the eggs are mainly concentrated in the corrugated paper, so that the eggs are more concentrated and easier to collect. The multiple effects of the odorant, the color of the ovipositing matrix and the seams of the comprehensive composition of the present invention can enhance the oviposition-attracting effect on the black soldier flies, thereby improving the concentrated oviposition and egg collection efficiency of the black soldier flies.

Description

technical field [0001] The invention belongs to the technical field of insect breeding, and in particular relates to a composition for inducing concentrated oviposition of black soldier flies and an application method thereof. Background technique [0002] With the development of the economy and the improvement of people's living standards, the demand for livestock and poultry products continues to increase, and the production scale continues to expand. At the same time as large-scale and intensive farming, the pollution caused by the excrement discharged is also becoming more and more serious. However, livestock and poultry manure is piled up in farms or septic tanks without being used, which not only pollutes the environment, but also causes serious waste of resources. [0003] The black soldier fly Hermetia illucens (Linnaeus, 1758), also known as the bright-spotted flat-horned soldier fly, belongs to the Diptera Soldier Fly family. The insect is widely distributed in mo...

AI Technical Summary

Problems solved by technology

So far, there are few reports about attracting black soldier flies to lay eggs. Although a small amount of published patents relate to the attractant of black soldier flies, the patent of CN 104798817 A as the application number has announced natural insecticides for gathering a variety of insects. The attractant is composed of animal blood meal, ammonia water, sodium bicarbonate, brown sugar, yellow rice wine, yeast and auxiliary materials; the patents with application numbers CN 103975902 A, CN 104026080 A and CN 103975901 A disclose the use of breeding leftovers to lure wild animals in the wild. Black soldier flies lay eggs, but these methods mainly use the sense of smell of black soldier flies, and the purpose of these methods is only to lure wild black soldier flies to obtain and reproduce wild populations. In the laboratory, there will be problems such as the above, which cannot well solve the bottleneck problem of attracting black soldier flies to concentrate eggs and collect eggs in production practice, and it is difficult to collect, quantify and transport the egg masses scattered around in time.
