Embodiment 1

[0017] First use scissors to cut off the shell of the tussah silkworm chrysalis, wash the tussah silkworm chrysalis with clean water, soak in a water bath for 6 minutes, the soaking water temperature is 60±1°C, then take it out, cut a small opening of the tussah silkworm chrysalis, squeeze out the midgut Take it out and remove it, and then use a cooking machine to grind the rest fully to get the tussah silkworm chrysalis pulp, then weigh 30g of the tussah silkworm chrysalis pulp; use a mortar to grind vitamin C tablets (vitamin C content: 6.2%, mass fraction) into pieces , weighed 3.2g; then shelled the eggs, stirred them evenly with a mixer, and then weighed 15g; then weighed 30g of brewer’s yeast powder, 15g of sucrose, 2g of trehalose, and 0.2g of potassium sorbate, and finally weighed all the The ingredients are poured into a blender and fully mixed to obtain the artificial feed for lacewing larvae.

Abstract

The invention discloses artificial feed for chrysopa perla larvae. The artificial feed comprises the following components in parts by weight: 20-40 parts of tussah pupa complete pulp, 10-30 parts of eggs, 20-40 parts of beer yeast powder, 10-25 parts of sucrose, 1-5 parts of trehalose, 0.1-0.5 part of vitamin C and 0.1-0.3 part of potassium sorbate. The artificial feed are rich in sources of raw materials and rich in various nutrient substances, and can be used for completely replacing mealybugs or rice moth eggs to meet the eating demand of the chrysopa perla larvae. The prepared artificial feed for chrysopa perla larvae is rich in nutrition, easy and convenient to prepare, and economical in price, saves time and effort, can be used for the large-scale breeding of chrysopa perla, and has a very good effect.

Description

Technical field: [0001] The invention belongs to the field of insect breeding, and in particular relates to an artificial feed for lacewing larvae and a preparation method thereof. Background technique: [0002] Lacewing is an important natural enemy of many agricultural and forestry pests such as aphids, whiteflies, mites, eggs and larvae of Lepidoptera, and is a natural enemy insect with great application value in pest biological control. Using indoor breeding technology is an important way to multiply natural enemies in large quantities and improve the control effect, and the preparation of artificial feed is the key to the natural enemy multiplication technology. At present, indoor breeding of lacewings mainly uses aphids, mealybugs, and rice moth eggs. In terms of artificial feed, a large amount of research has also been done at home and abroad, mainly using fly maggot powder, pig liver, beef, beef liver, soybean or soybean hydrolyzate as the main components.
