A kind of method that utilizes sweet potato to raise fungus mosquito

Abstract

The invention discloses a method for utilizing sweet potatoes to raise fungus gnats, and belongs to the field of artificial raising of insects. The method comprises the steps of firstly laying vermiculite in a container, then placing the sweet potatoes on vermiculite and then wrapping a layer of vermiculite; placing the container into an inset raising cage, proportionally placing male and female imagoes of the fungus gnats into the inset raising cage and finally conducting raising in a biochemical cultivating box. By means of the method, the sweet potatoes used as feed are rich in nutrition, can meet growth and development requirements for all generations of the fungus gnats and improve the breeding efficiency and quality; vermiculite high in water retention and breathability is used as amedium, and a good environment condition is provided for breeding the fungus gnats. The survival rate, pupation rate, eclosion rate and haplometrotic egg laying amount of the fungus gnats are obviously higher than those in the prior art, and the breeding effect is good; obtained larvae are high in consistency and stability, and the credibility and the reliability of a biological test are accordingly improved; besides, the method is applicable to large scale breeding. The raw materials are easy to obtain, the method is simple, and the raw material and labor cost is low.

Description

technical field [0001] The invention belongs to a method for artificially raising insects, in particular to a method for raising fungus mosquitoes with sweet potatoes. Background technique [0002] Fungi mosquitoes are the collective name for insects of the families Mycetophilidae and Sciaridae of the order Diptera. Among them, the insects of the genus Bradysia and Lycoriella in the genus Bradysia are the most serious damage to crops, including Bradysia odoriphaga, which belong to the genus Bradysia, Bradysia difformis and Bradysia minpleuroti, and Lycoriella pleuroti belonging to the genus Lycoriella pleuroti, etc. [0003] Bradysia odoriphaga, commonly known as leek maggot, is currently the main reason for the reduction of leek production. The insect is widely distributed in Northeast my country, North China, Central China and Northwest China, and is a unique pest in my country. Leek maggots have a wide range of hosts. In addition to harming leeks, garlic, green onions ...

Problems solved by technology

In the past breeding methods, the original host plant or fungal mycelia were mainly used as feed. For example, in the artificial breeding of the traditional chive tardigrade, leek segments were used as feed, that is, leeks were collected, impurities were removed, peeled, and the leeks were cut into 4 pieces. ~6mm small section, for the larvae of Chive tardigrades. Natural leeks are used as feed during the whole breeding process. The main problem of this breeding method is that there are certain pesticide residues in leeks that cannot be completely removed. Kinds of medicated chives are more toxic to fungus mosquitoes, resulting in incoherent breeding, making it impossible to carry out multi-generation breeding of fungus mosquitoes, and causing poor consistency of the fungus mosquitoes tested, reducing the credibility and representativeness of the test results; Secondly, the leeks obtained by this method have poor sensitivity to tardigrades, resulting in inaccurate test results; in addition, the leek itself is not easy to preserve, and is easy to rot and mold, so fresh leeks and containers need to be replaced frequently, which makes the breeding process very cumbersome and troublesome, and raises the cost of breeding , and it is difficult to carry out large-scale breeding

[0011] According to the search, sweet potato is not the host of fungus mosquitoes, and there is no report on the use of sweet potato as feed for artificial breeding of insects; nor is there any report on the use of vermiculite for insect reproduction.
