The present disclosure belongs to the technical field of excrement treatment, and specifically provides a method for resource utilization of pig manure mixed with fly larvae and fly ash, comprising: S1, feeding pig manure mixed with fly larvae and fly ash in a circulating fluidized bed; S2, periodically measuring the length and weight gain of the larvae, and measuring the crude protein, crude fat, waste reduction rate and intestinal microbiome of the larvae after the conversion is completed; S3, determining the appropriate addition ratio of the fly ash in the circulating fluidized bed according to the measured indexes. The fly larvae reduce the mixture of pig manure and fly ash, and the worm manure produced not only meets the requirements of organic fertilizer for organic matter, nitrogen, phosphorus and potassium nutrients, but also is rich in silicon elements which may promote rice growth. After the fly ash enters the worm intestine, it undergoes a strong acid digestion link, so that the fly ash experiences a similar acid modification process, and the strong acid corrosion causes micropores to appear on the surface of the fly ash particles, which may play an important role in soil structure and fertility.

The invention provides a fruit fly larva collecting device and a using method, and belongs to the technical field of biology. The problems that in the prior art, damage to larvae is large, operation is tedious and time-consuming, and separation of the larvae and feed is not thorough are solved.

According to the invention, the problem of larva damage caused by picking and metal gauze filtration is solved, the fruit fly larva is milder, and the damage is greatly reduced; meanwhile, the defect that a traditional picking mode wastes time is overcome, operation is more convenient, time is saved, larvae and feed are separated more sufficiently in the operation process, additional complex clamping steps are not needed, and the problems that feed residues exist, and clamping is still needed after centrifugation are effectively solved.

The application discloses a medicine injection method for killing camel head fly larvae parasitizing in the nasal cavity of a bactrian camel. A pair of non-bony structures similar to a triangle and the size of a thumb are arranged at the joint of nasal bone, maxillary bone and frontal bone. The pair of non-bony structures are at the same horizontal level with the eye socket of the bactrian camel, are located at the intersection of the inner corner of the eye and the upper edge of the eye socket, and are away from the eye socket by 4-5 cm. After a syringe is vertically inserted into 2-3 cm at the site, the needle of the syringe can reach the medial part of the concha nasalis. After the site is inserted into 2.5-3 cm in the clockwise direction and is inclined by 45 degrees, the needle can reach the lateral part of the concha nasalis. The medicine injection method can directly inject the insect killing medicine to the parasitizing position of the first instar larvae, and the purpose of killing the first instar larvae is achieved. The medicine injection method provides a new method for killing the first instar larvae in the overwintering period, and can reduce the economic loss of the camel raising industry caused by the nasal fly maggot disease.

The invention belongs to the field of fly maggot breeding, and provides a method for integrally breeding fly maggots by using pig manure in Tibet, which comprises the following sequential steps: hatching period: placing red-head fly pupae in a constant-temperature and constant-humidity environment for eclosion, controlling the environment temperature to be 25-30 DEG C and the relative humidity to be 50-70%, and immediately providing feed and clean drinking water after the pupae are subjected to eclosion into adult flies; by constructing a pig manure-fly maggot-protein feed-organic fertilizer integrated breeding mode, the double problems that in Tibetan pig breeding in the Tibetan alpine region, the manure treatment cost is high, transportation is difficult, the resource utilization rate is low, and protein feed depends on outsourcing for a long time are effectively solved; and in combination with self-circulation maintenance of red-head fly populations introduced in Sichuan, the egg laying rate and egg hatching rate of adult flies are increased, and the inhibition effect of plateau low-temperature oxygen-deficient environment on fly maggot growth is overcome.
