Dipteran insect separation method

Abstract

The invention relates to the technical field of insect breeding, in particular to a diptera insect separation method, a separation device is used for separation by utilizing biological habits of biological oxygen taxis and high temperature avoidance, the separation device comprises a separation box and a partition plate, and the separation box is provided with an insertion groove for the partition plate to penetrate through. The separation method comprises the following steps: S1, adding a to-be-separated material containing insect bodies and an organic fertilizer to the bottom in a separation box, and paving the to-be-separated material; s2, a substrate is added into the separation box, and the substrate is flatly laid on the to-be-separated material; s3, the substrate is added into the separation box again every 20 minutes, and the substrate added at the later time is flatly laid on the substrate added at the previous time; s4, after all the substrates are added, standing is conducted for a period of time, partition plates penetrate through the insertion grooves and abut against the inner wall of the separation box, and insect bodies are located above the partition plates; s5, insect bodies are taken out of the separation box. The method is high in separation rate, simple and efficient, and is not limited by substrate humidity, state, conversion completeness and time and age conditions of insect bodies.

Description

technical field [0001] The invention relates to the technical field of insect breeding, in particular to a method for isolating dipteran insects. Background technique [0002] In 2020, the annual output of food waste in my country will be as high as 120 million tons, 4 billion tons of poultry and livestock manure, 200 million tons of barren and polluted land to be improved, and 143 million tons of imported grain. Then you can get more than 160 million tons of high-protein worms and more than 1.6 billion tons of organic fertilizers, which not only solve the problems of environmental pollution, food safety problems that rely on imports of protein feed, and soil improvement problems, but also the cycle is short, 3-10 days. Transform a batch with high added value. [0003] Manpower accounts for at least one-third of the breeding cost in Diptera insect breeding, and the separation of insects and fertilizers is the most labor-intensive and also the most critical part. At present, t...

Problems solved by technology

[0005] The purpose of the present invention is to solve the problems existing in the background technology, and create a unique method based on the biocompatibility of insects avoiding substrate accumulation and heat production to form high temperature and accumulation anoxic and tending to oxygen, creating a high separation rate, simple and efficient, and unlimited substrate humidity and state The separation method of Diptera insects, which is limited by the completeness of transformation and the age of the insect body, saves costs and solves the bottleneck problem of high cost of breeding and separating Diptera insects
