Problems solved by technology

An insect that can transform livestock and poultry manure was trapped near the chicken farm. According to the feeding habits of the insect, a set of transformation technology using insects to treat livestock and poultry manure was developed, so as to fully solve the environmental problems caused by the accumulation of manure in current farms. Pollution problems, while turning waste into treasure, transforming it into high-quality alternative animal protein feed, laying the foundation for future practical application and theoretical research

Embodiment 1

[0026] Example 1: Trapping and domestication of wild soldier flies

[0027] 1. Outdoor trapping of wild soldier flies

[0028] In the suburbs of Wuhan (near Nanhu Lake, Hongshan District, Wuhan City) near the place where chicken manure, pig manure or cow manure is piled up, fill a plastic basin with chicken manure (chicken manure with housefly larvae is the best), and use branches to build a support , put the plastic basin filled with chicken manure on the support to avoid the interference of carnivorous insects such as ants, and lure the adult soldier flies to lay eggs. After hatching, collect the larvae and bring them back to the laboratory;

[0029] Or near the place where chicken manure, pig manure or cow manure is piled up, fill a plastic basin with chicken manure (chicken manure with housefly larvae is the best), and then put a plastic net on the plastic basin to attract bright spots Adult flathorned soldier flies came to feed, and the captured adults were brought back ...

Embodiment 2

[0033] Example 2: The biological characteristics of the Wuhan strain of the bright-spotted flat-horned soldier fly and the comparison with the Guangzhou strain and the Dallas strain

[0034] 1. Egg stage

[0035] In the 3 strains, 30 egg masses produced at the same time were respectively placed in three jars, covered with wet gauze, and the hatching time of each egg mass was recorded. The average hatching time of the 30 egg masses was the egg stage.

[0036] Put a small amount of artificial feed in the plastic washbasin, put a plastic net on the plastic washbasin, put the horse manure paper with holes in the eggs on the plastic net, and cover a bottomless plastic washbasin of the same size on the top. Cover with damp gauze to retain moisture and keep flies out. Then, put it in a laboratory with a temperature of 24-30°C and a humidity of 75-80% to make it warm, the hatched larvae will automatically fall on the artificial feed, and the artificial feed collected from the newly h...

Embodiment 3

[0061] Example 3: Comparison of the transforming abilities of the light-spotted flat-horned soldier fly Wuhan strain, Guangzhou strain and Dallas strain for handling pig manure, chicken manure and cow manure respectively

[0062] 1. Comparison of the weight of larvae of three strains of soldier flies with bright spots transformed into pig manure, chicken manure and cow manure

[0063] (1) Comparison of weight of larvae transformed from pig manure, chicken manure and cow manure of Wuhan strain

[0064] When the three kinds of manures were transformed, the larvae yields obtained from the three kinds of manures were significantly different among species (F=734.65, df=2, P<0.0001), and the dry weight of larvae obtained from the chicken manure species was the highest. The larvae obtained in manure are the lowest, the dry weight of larvae obtained in pig manure is in the middle, and the dry weight of larvae obtained in chicken manure is 2.5 times that of cow manure, which is about 2...

Abstract

The invention relates to the technical field of field acquisition, artificial domestication and mass propagation of insects and in particular discloses a domestication and culture method and an application of hermitia illucens WH. The eggs and adults of Wuhan wild hermitia illucens are acquired and respectively raised and domesticated, thus obtaining the stable artificial propagation strain and creating a technology of mass raising. The hermitia illucens WH larvae raised in mass are utilized to transform pig manures, chicken manures and cattle manures respectively and accumulation of livestock and poultry manures can be reduced by more than 50% through treatment. The obtained prepupa contains 35-39% of crude protein, the protein is formed by 17 amino acids, the prepupa contains 33-35% of fat and the fat can serve as the high-quality feed ingredient and nutrition. The domestication and culture method has the following advantages and beneficial effects: the hermitia illucens larvae are utilized to transform livestock and poultry manures; the method has the advantages of simpleness and convenience in operation, deodorization, pathogenic bacteria removal, zero energy consumption, easiness in popularization and the like; and the environmental pollutants are effectively utilized and the high added value product can be obtained.

Description

technical field [0001] The invention relates to the technical fields of field collection, artificial domestication and mass propagation of insects, in particular to a domestication and breeding method and application of a bright-spotted flat-horned soldier fly Wuhan strain. Background technique [0002] 1. Light-spotted flat-horned soldier fly [0003] The bright-spotted soldier fly (Hermitia illucens) is a species of insect in the family Soldieridae of the order Diptera. The gadfly-like black insects originated in the savannahs of South America and feed mainly on animal droppings and carcasses. The light-spotted soldier fly is distributed in most of the tropical and temperate regions of the world, and it is also very common in my country. More than 170 species are known in China, and are recorded in Beijing, Hebei, Fujian, Guangdong, Guangxi, Hainan, Hubei and other regions, and generally appear from May to November every year. [0004] 2. Livestock manure [0005] With...
