Embodiment 1

[0030] In the feeding method of the present embodiment, the culture substrate is made of the following raw materials in the ratio of parts by volume: 2 parts of coconut bran; 1 part of peat. Add water to the culture substrate and stir evenly, it is only necessary to be moist without outflowing water. The larvae of the emaciated dirty fly and its prey, the larvae of the fungus gnat, live in the culture medium. The culture medium that each emaciated dirty fly larva occupies is 0.5 cubic centimeter. 1-3 day-old thin and weak fly larvae, each thin and weak fly larva was fed with 3 3rd-instar fungus mosquito larvae; from 4-day-old to pupal stage, each thin and weak fly larva was fed with 5 4th-instar fungus mosquito larvae every day .

Embodiment 2

[0032] In the breeding method of this embodiment, the culture substrate is made of the following raw materials in the ratio of parts by volume: 1 part of peat; 3 parts of mushroom dregs; 2 parts of sawdust. Add water to the culture substrate and stir evenly, it is only necessary to be moist without outflowing water. The larvae of the emaciated dirty fly and its prey, the larvae of the fungus gnat, live in the culture medium. The culture medium that each emaciated dirty fly larva occupies is 2 cubic centimeters. 1-3 day-old thin and weak fly larvae, each thin and weak fly larva was fed with 5 2nd-instar fungus mosquito larvae; from 4-day-old to pupal stage, each thin and weak fly larva was fed with 7 third-instar fungus mosquito larvae every day .

Embodiment 3

[0034] In the breeding method of the present embodiment, the culture substrate is made of the following raw materials in the ratio of parts by volume: 1 part of peat; 7 parts of vermiculite; 5 parts of mushroom dregs; 3 parts of sawdust. Add water to the culture substrate and stir evenly, it is only necessary to be moist without outflowing water. The larvae of the emaciated dirty fly and its prey, the larvae of the fungus gnat, live in the culture medium. The culture medium that each emaciated dirty fly larva occupies is 1.5 cubic centimeters. 1-3 day-old thin and weak fly larvae, each thin and weak fly larva was fed with 7 3rd-instar fungus larvae; from 4-day-old to pupal stage, each thin and weak fly larva was fed with 9 second-instar fungus larvae per day .

Abstract

The invention discloses a culture medium and method for feeding predatory coenosia larvae indoors. The culture medium is formed by adding water in one of the following components or adding water in the mixture of many of the following components which are mixed according to a random proportion: coconut chaff, peat, turf, vermiculite, mushroom residues and wood chips, wherein the amount of the added water is in a standard that no flowing water exists in the culture medium. The method for feeding the predatory coenosia larvae indoors comprises the following steps: 1) placing newly hatched larvae of predatory coenosia in a culture vessel, and adding the culture medium in the culture vessel according to the proportion that each newly hatched larva of the predatory coenosia requires 0.5-2 cubic centimeters of the culture medium; 2) feeding the newly hatched larvae under the temperature of 23-27 DEG C and 65-75% of relative humidity, feeding each coenosia larva of 1-3 days with 3-9 larvae of fungus gnats of 1-3 days every day, and feeding each coenosia larva of 4 days with 3-9 larvae of fungus gnats of 2-4 days every day. The method disclosed by the invention is simple, is wide in raw material source, and is low in production cost.

Description

technical field [0001] The invention relates to the technical field of insect rearing, in particular to a culture substrate and method for indoor feeding of predatory fly larvae. Background technique [0002] The extensive use of chemical pesticides has brought about a series of problems such as increased pest resistance, increased environmental pollution, excessive pesticide residues in agricultural products, and frequent human and animal poisoning incidents. It is more important and urgent to vigorously develop pest biological control, produce green, organic and safe agricultural products, and take a sustainable development strategy. Predatory natural enemy insects refer to insects that specifically feed on other insects or animals. Such natural enemy insects directly eat part or all of the insect body; or penetrate the pest body and suck the pest body fluid to kill it. Large-scale production of natural enemy insects to prevent and control various major, important and qua...
