Embodiment 1
[0038] Embodiment 1 General embodiment
[0039] A method for collecting eggs of Chrysocephala larvae, comprising the production of egg collecting material based on pig manure and an optimized method for collecting eggs, specifically comprising the following steps
[0040] (1) Preparation of egg collection matrix: the egg collection matrix is selected from the feces of 2-3 month old piglets excreted on the same day, and the feces do not contain fly killing agents and antibiotics; by drying or adding 2-3 The pig urine of month-old piglets is made to have a water content of 75%, and then placed at room temperature for anaerobic fermentation for 6-12 hours to obtain a fluffy egg collection matrix;
[0041] (2) Placement of the ovum collection matrix: first the bran with a water content of 65% is tiled in the ovum collection box, and the thickness reaches 2cm, then the above-mentioned ovum collection matrix is placed on the four corners of the ovum collection box and along the ...
Embodiment 2
[0045] Example 2 Comparative Example
[0046] In this example, we compared the following different implementations:
[0047] (1) With reference to the general method of Example 1, relevant comparative experiments have been carried out on the selection of pig manure of different pig ages, specifically: select 2-3 months, 4-5 months, 6-7 months after pig excretion , 8-9 months, 10-11 months, and 12 months old pig manure was used as the egg collection matrix for natural room temperature anaerobic fermentation treatment, fermented for 6 hours, and the eggs were collected at the end of the treatment. See the egg collection effect diagram figure 2 , spawn rate see image 3 .
[0048] (2) With reference to the general method of Example 1, relevant comparative tests have been carried out on the selection of pig manure water content, specifically: selecting fresh pig manure with water content of 65%, 75%, 85% to carry out natural normal temperature anaerobic fermentation Process, f...

Abstract
The invention belongs to the artificial culture insect technical field, and specifically relates to a Chrysomyia megacephala larva egg mass collecting method and application; the invention comprises egg mass collecting material using pig dung as matrix and an egg mass collecting method; the method is characterized by comprising the following steps: 1, using pig dung freshly excreted in the same day as the egg mass collecting matrix, making water content up to 75%, and carrying out anaerobic fermentation for 6-12 hours, thus obtaining the egg mass collecting matrix; 2, thickening the egg mass collecting matrix on corners and edges of an egg mass collecting disc; 3, placing the egg mass colleting matrix into a fly cage for 8-18 hours every day, collecting fly eggs in every 2 hours, storing the egg mass of the same day at the temperature of 4 DEG C, and concentrating and hatching the eggs at 30 DEG C; 4, adding egg mass collecting matrix at proper time after the egg mass is collected, and keeping the matrix moist; 5, covering wheat bran of 65% water content on the surface of the egg mass, using a film for moisture retention, and hatching the eggs at 30 DEG C. The novel method can solve the Chrysomyia megacephala simultaneous hatching problems, and the egg mass collecting matrix is better than a normal method; the Chrysomyia megacephala larva egg mass collecting method and application are low in cost, good in egg collecting effect, and high in egg survival rate.
Description
technical field [0001] The invention belongs to the technical field of artificially breeding insects. Specifically, it relates to a method for collecting eggs of Chrysocephala larvae and an application thereof. Background technique [0002] The annual discharge of pig manure in my country is as high as 213 million tons, but the utilization rate of resources is insufficient. The use of golden fly to deal with pig manure not only efficiently and effectively solves the problem of environmental pollution within 3-5 days, but also provides high-quality protein feed and organic Fertilizer provides a new way for resource utilization of pig manure. [0003] Generally speaking, the water content of pig manure excreted naturally by pigs is between 68-76%. [0004] Traditionally, the ovum-collecting matrix used by the artificial culture of Chrysalis chinensis mainly contains the following raw materials: animal carcasses, fermented bran with a water content of 65%, a mixture of ferment...
