Indoor large-scale breeding method for corydalus cornutus larvae and pupae

Abstract

The invention discloses an indoor large-scale breeding method for corydalus cornutus larvae and pupae.The method comprises the following steps that 1, a breeding room with the effects of ventilating, heat dissipating and warm keeping is built; 2, the larvae are put into breeding boxes, partitions which have the shield effect and can prevent the larvae from killing one another are arranged in the breeding boxes, each 1-3-instar larva feeds on 1-5 rotifers or other similar food every day, automatic feeding along with water flow is performed on the larvae of 4 instars or older, and the feeding quantity and times are determined according to the food remaining condition on the next day; 3, pupation plates are placed on the water surfaces in the breeding boxes, a sand and soil mixture is put in the pupation plates, covering objects or partitioning parts are arranged on the sand and soil mixture, and when the larvae grow to the pupation stage, the larvae voluntarily crawl into the sand and soil mixture from water to pupate until the larvae grow into imagoes through eclosion.According to the method, allopatric artificial indoor large-scale breeding of corydalus cornutus can be achieved, and the survival rate and the pupation rate of the corydalus cornutus larvae can be significantly increased.

Description

technical field [0001] The invention relates to insect breeding technology, in particular to an indoor large-scale breeding method for sand crawler larvae and pupae. Background technique [0002] Sand crawler is the common name or collective name for the larvae of the insects of the family Odontidae (mainly the genus Megalodon and some large genus Odonidae). It has important medicinal and edible value, and has the reputation of "animal ginseng". Japan has a long history of use, and now it has become a very expensive and in short supply important nourishing food for both medicine and food in Sichuan, Yunnan, Guizhou and other places. Not only can you eat delicious dishes of sandworms in large and small restaurants, It also has the merits of crawling sandworms in the treatment of nocturia in children and frequent urination in the elderly, and has great potential to be developed into health care products. [0003] The resources of sand crawling insects in nature are huge, but ...

Problems solved by technology

Shi Zhixiong proposed the use of single-chip computer Technology, computer control technology, sensor technology and electronic technology, artificially simulate the natural environment to develop and breed sandworms, but most of them are theoretical assumptions, basically meaningless to artificial breeding

Shi Zhixiong also gave the establishment method of automatic breeding system facilities in the paper "Research on Automatic Breeding Technology of Sand Climbing Worm Based on STC12C5A60S2 Single-chip Microcomputer" in Journal of Xichang University (Natural Science Edition) (2011,25(3):48-51,57) And the design circuit diagram and technical parameters of the control equipment, the article also elaborates on the so-called "breeding technology", but in fact many of them are too general, most of the content is not suitable for breeding, let alone indoor artificial breeding

In addition, most of the content of this article is repeated with the paper "Production and Breeding Technology of Sand Climbing Worms" published by Wang Fubin and Liu Yusheng (Agricultural Knowledge, 2009(8):40-41). Insect breeding technology, but none of them are indoor breeding, and most of the technologies are general, the breeding efficiency is low, and many key technologies are not mentioned. Generally speaking, the technology is immature and the practicability is not strong.
