Embodiment

[0019] The preparation method of fly maggot powder: first put the fly maggot into -20 ℃ refrigerator for 5 minutes to freeze to death, then sterilize the dead fly maggot with 1% NaClO solution for 10 minutes, wash it repeatedly with distilled water, and use a constant temperature blast drying oven to dry it. Dry at 50° C. for 8 hours to obtain dried maggots. Finally, grind the dried maggots with a tissue grinder and pass through an 80-mesh sieve to obtain the required maggot powder.

[0020] Preparation of artificial feed for ladybug larvae: 5 g of pig liver, 1.5 g of fly maggot powder prepared in Example 1, 1.5 g of yeast extract, 2 g of sucrose, and 2 g of honey. The above ingredients are accurately weighed with a ten-thousandth balance, placed in a disposable plastic cup, mixed with a medicine spoon, and refrigerated in a 4°C refrigerator for later use.

Abstract

The invention belongs to the field of feeding of natural enemy insects and in particular relates to an artificial feed for harmonia axyridis larvae and a preparation method of the artificial feed. The artificial feed for harmonia axyridis larvae is prepared from the following components in parts by weight: 5 parts of pork liver, 0.5-1.5 parts of dried powder of housefly larvae, 1-2 parts of yeast extract, 1-3 parts of saccharose and 1-2 parts of honey. The preparation method comprises the steps of preparing pasty pork liver, preparing dried powder of housefly larvae and mixing all the components. The components of the artificial feed are readily available, the investment is low, the production cost is low, and the preparation method is simple, can be operated easily and is suitable for feeding harmonia axyridis larvae in a large-scale manner.

Description

technical field [0001] The invention belongs to the field of natural enemy insect breeding, and in particular relates to an artificial feed for Heterochromia larvae and a preparation method thereof. Background technique [0002] As one of the important means of comprehensive management of pests, biological control has the characteristics of high benefit, no pollution, safe for humans and animals, and conducive to environmental protection. With the development of modern agriculture, it has been widely valued. As a special resource, natural enemy insects It is also more and more accepted by people. Developed countries began to develop the natural enemy insect industry in the 1960s. At present, there are about 150 kinds of natural enemies in the world that are commercially produced and sold. certain social and economic benefits. [0003] The expansion and utilization of natural enemy insects in my country have also achieved remarkable results, and artificial breeding of major...
