Embodiment 1

[0033] A kind of artificial feed for adults of red-tailed dung beetle fly and its preparation method:

[0034] In terms of weight percentage, it includes 50g of soybean powder, 40g of milk powder, and 10g of granulated sugar, which are mixed and stirred evenly with a small mixer.

Embodiment 2

[0036] A kind of artificial feed for the larvae of the red-tailed dung beetle fly and its preparation method:

[0037] First, the fresh pig lungs bought in the market are divided into several pieces with scissors, and then the pig lungs are broken into a minced shape with a small meat grinder, and then calculated by weight percentage, including 40g of broken pig lungs, 20g of pig manure, 25g of cow manure, 10g of milk powder, and 5g of agar powder were mixed and stirred evenly with a small mixer. After being treated in an oven at 150°C for 20 minutes, it was naturally cooled to room temperature for later use. The baked artificial feed was mixed with 20g of purified water. That is, the artificial diet for the larvae of the red-tailed dung fly was obtained.

Embodiment 3

[0039] A kind of artificial breeding method of red-tailed dung fly, comprises the steps:

[0040] Collection and rearing of adults: trap red-tailed dung flies on grass in the wild with carrion and pig manure. After species identification, they are put into insect breeding cages with a size of 35cm*35cm*35cm. One of the petri dishes is filled with cotton soaked in clear water, which is used to provide water and a place for the adults to stand; the other culture dish is filled with the prepared artificial diet for the adults of the red-tailed dung fly, which is used to provide the adults with water. nutrition, and then place the insect breeding cages at a constant temperature of 25°C and a humidity of 75% in an entomological artificial climate box with shading or low light to continue development.

[0041] Induction of larvae: After living in the insect breeding cage for about 10 days, the mating phenomenon of male and female adults was observed, and the larvae of the prepared r...

Abstract

The invention provides an artificial feed for adult and larva of red-tail drosophila melanogaster as well as a preparation method and an artificial feeding method of the red-tail drosophila melanogaster. The artificial feed comprises the following components in percentage by weight: 25-50% of soybean meal, 25-50% of milk powder and 10-15% of berry sugar. The artificial feed comprises the following components in percentage by weight: 20-40% of fresh pig lung, 10-30% of pig manure, 10-30% of cow dung, 5-10% of milk powder, 3-5% of agar powder and a certain amount of purified water. The preparation method comprises the steps of smashing, stirring, baking and water mixing. The breeding method comprises the steps of breeding preparation, adult breeding, larva induction, larva breeding, pupation observation and adult eclosion. According to the artificial feed and the artificial feeding method for the adult and the larva of the red-tail droppy fly, the artificial feeding of the red-tail droppy fly is realized, the technical problems of asynchronous development and the like in the feeding process of the red-tail droppy fly are solved, and a better material is provided for developing the corpse-like behavior research of the red-tail droppy fly.

Description

technical field [0001] The invention relates to the field of feeding necrophagous insects, in particular to an artificial feed for adults and larvae of the red-tailed dung fly and a preparation method thereof, and also to an artificial feeding method for the red-tailed dung fly. Background technique [0002] Forensic entomology is a new cross-discipline that uses the growth and development of necrophagic insects to measure the death time of putrid corpses (PMI), which is of great significance to the detection of criminal cases. The red-tailed dung fly (Diptera: Sarcophagidae) is a common necrophagous fly on cadavers. It has unique advantages in PMI deduction and other aspects, and is an important necrophagous fly. Artificial rearing of D. red-tailed flies is an important way to provide a large number of standard test insects with consistent age and nutritional status for scientific experimental research, and it is the basic guarantee for research on necrophagic behavior char...
