Problems solved by technology

At present, mass breeding is mainly fed by living hosts such as aphids, and the growth and development of ladybugs and aphids cannot be quantitatively controlled during the breeding process. The reproductive efficiency and quality are unstable, which limits its mass reproduction and application.

Embodiment 1

[0017] The feed for raising the heterochromia larvae is made up of the raw materials of following weight ratio:

[0018] Tussah freeze-dried powder: honey: sucrose: vegetable oil: aphid freeze-dried powder = 54.3: 21.2: 21.2: 1: 1.3.

[0019] The method for preparing feed for raising the heterochromia larvae comprises:

[0020] 1) Freeze-dried powder of tussah silkworm: Take healthy tussah silkworm chrysalis, grind it into a pulp with a food processor, obtain the freeze-dried powder through a freeze-drying apparatus, put it in the refrigerator, and refrigerate at -18°C-4°C for later use.

[0021] 2) Freeze-dried powder of aphids: take aphids, grind them into a slurry with a food processor, obtain freeze-dried powders through a freeze-dryer, put them in a refrigerator, and refrigerate them at -18°C to 4°C for later use.

[0022] 3) Dissolve honey and sucrose with 1-2% of its own weight in clean water to form a solution, then pour the above solution into the mixed powder of tus...

[0025] Materials and Methods

[0026] Heterochromia adults were collected from the Hancunhe Science and Technology Demonstration Park in Fangshan District, Beijing and the corn field of Beijing Academy of Agriculture and Forestry Sciences in early May 2004. After being fed indoors with Vicia faba aphid for a period of time, they laid eggs for later use.

[0027] This test is divided into two parts before and after, and each part includes control and has six groups of feed treatments, and the feed ratio is by weight.

[0028] Feed preparation methods, including:

[0029] 1) Freeze-dried powder of tussah silkworm: Take healthy tussah silkworm chrysalis, grind it into a pulp with a food processor, obtain the freeze-dried powder through a freeze-drying apparatus, put it in the refrigerator, and refrigerate at -18°C-4°C for later use.

[0030] 2) Freeze-dried powder of aphids: take aphids...

Abstract

The invention relates to a feed for raising Harmonia axyridis larvae. The feed comprises freeze-dried tussah powder, honey, sucrose, plant oil and freeze-dried aphid powder according to a weight ratio of (50-60):(20-30):(15-25):(0-2):(0-2). The above formula of the feed can meet nutrition demands of every age growth of Harmonia axyridis larvae. The feed has the advantages of low cost and easy obtaining of raw materials, convenient preparation, easy operation, factory production facilitation, and provision of technical and material bases for large-scale breeding and application of Harmonia axyridis.

Description

technical field [0001] The invention relates to a feed for raising heterochromia larvae, which belongs to the field of agricultural feed. Background technique [0002] Harmonia axyridis (Pallas) belongs to Coleoptera, Coccinidae, and is a holometabolous insect. Heterochromia is distributed in China, Russia, Mongolia, North Korea, Japan and other places, basically all over my country. [0003] Heterochromia can eat all kinds of aphids and pine scales, mealybugs, cotton scales, psyllids, mites, eggs of some Lepidoptera and Coleoptera insects, young larvae and pupae, etc., but they like to eat aphids. It is an important predatory natural enemy insect in agriculture and forestry. [0004] Heterochromia has attracted widespread attention due to its large food intake, large number of eggs, and strong adaptability. It is an excellent natural enemy species for biological control. At present, mass breeding is mainly fed by living hosts such as aphids, and the growth and developmen...
