Method for adjusting and controlling feeding of raw materials to hermetia illucens larvae

Abstract

The invention belongs to the technical field of hermetia illucens breeding, and particularly relates to a method for adjusting and controlling feeding of raw materials to hermetia illucens larvae. According to the characteristic that the hermetia illucens larvae are photophobic, the hermetia illucens larvae are stimulated through illumination, and when illumination of which the illumination intensity is higher than a certain illumination intensity is given, the hermetia illucens larvae enter the raw materials so as to take in the raw materials from inside to outside; when illumination of whichthe illumination intensity is lower than a certain illumination intensity is given or illumination does not exist at all, the hermetia illucens larvae climb out from the raw materials and take in theraw materials from outside to inside; and therefore, through adjusting different illumination intensities, the hermetia illucens larvae are forced to change intake positions and the depth of the rawmaterials, and the purpose of improving raw material intake efficiency is finally achieved.

Description

technical field [0001] The invention belongs to the technical field of black soldier fly breeding, and in particular relates to a method for regulating black soldier fly larvae feeding raw materials. Background technique [0002] Black soldier fly (Hermetia illucens L.) is a saprophytic Soldier Fly insect, which is native to America and has been widely distributed all over the world, mainly between 40 degrees north and south latitude. Black soldier fly larvae can feed on raw materials, such as kitchen waste and livestock and poultry manure, and transform the raw materials into highly nutritious insect bodies and insect dung. Insect manure is a natural organic fertilizer. The worm body contains high protein and high energy, not only can be directly used as feed raw materials for aquaculture, but also can extract antimicrobial peptides, chitin and other biologically active substances to increase the value. Therefore, raising black soldier fly larvae in large quantities is no...

Problems solved by technology

[0004] However, due to the different sources of raw materials, the degree of dryness, bulkiness and distribution of nutrients are quite different, black soldier fly larvae will be selective when feeding: if the humidity of the garbage is too high or the temperature is too high, the larvae will Feed from the outermost side of the raw material to the inside, and spread the garbage raw materials continuously during the feeding process until all the garbage is eaten; if the garbage is dry or the temperature is low, the larvae will pick from the inside out Although the above two feeding processes can consume most of the nutrients in these raw materials, due to the selectivity of feeding, the consumption of raw materials will not be complete

[0005] In order to improve the feeding efficiency and uniformity of the larvae, the existing breeding methods generally add auxiliary materials to the raw materials to treat the raw materials to a uniform dry humidity standard, but this will lead to high breeding costs

Therefore, in order to save costs, the existing breeding equipment has added turning and throwing equipment to alleviate the problem of incomplete feeding, but when turning and throwing raw materials, the turning and throwing equipment will stir the raw materials that have been eaten and those that have not been eaten. Together, it also increases the amount to be processed and the difficulty of feeding, so it cannot fundamentally solve the problem of incomplete feeding
