Embodiment 1

[0038] A kind of method of indoor raising mole-shaped ladybug, concrete steps are as follows:

[0039] 1) raising aphids, raising aphids on host plants to form seedling trays;

[0040] Feeding wheat aphids

[0041] 1. Germination of wheat seeds

[0042] Soak the wheat seeds at 25°C for 4-6 hours, and then put them in a germination machine for 24 hours to germinate. After the wheat seeds are white, they can be sown.

[0043] 2. Planting of wheat

[0044]Most of the wheat is planted in trays, and evenly sprinkle a layer of dewy wheat seeds on the trays, and then evenly cover with a layer of pearl salt, and then spray water evenly with a watering can until it is completely moist and there is no obvious water accumulation.

[0045] A small amount of wheat is sown in transparent plastic pots with a diameter of about 10 cm and holes in the bottom, and the plastic pots are evenly placed on a large tray to avoid water leakage. Spread paper towels evenly in a transparent plastic ba...

Embodiment 2

[0073] A kind of method of indoor raising mole-shaped ladybug, concrete steps are as follows:

[0074] 1) raising aphids, raising aphids on corresponding host plant seedlings to form seedling trays;

[0075] Raise wheat aphids, sorghum aphids, corn aphids respectively according to the method described in Example 1;

[0076] 2) Feeding of ladybugs

[0077] ① lay eggs

[0078] At 25°C, under the condition of 60% relative humidity, take the seedling trays with aphids cultivated in step 1) and put them in the insect cages to raise the adult mole beetles, and place 2 pots of corn seedlings to lure the mole beetle Worms lay eggs, every 2 days, change the food;

[0079] The three plants of wheat aphid, sorghum aphid and corn aphid are placed in insect cages according to the ratio of 1:1:1.

[0080] The seedling tray is a planted host plant with aphids;

[0081] ②Collection of eggs

[0082] The newly emerged adult beetles began to lay eggs after feeding on 6 days, and collected ...

Embodiment 3

[0089] A kind of method of indoor raising mole-shaped ladybug, concrete steps are as follows:

[0090] 1) raising aphids, raising aphids on corresponding host plant seedlings to form seedling trays;

[0091] Raise wheat aphids, sorghum aphids, and corn aphids respectively in the manner described in Example 1;

[0092] ① lay eggs

[0093] At 25°C, under the condition of 80% relative humidity, take the seedling trays with aphids cultivated in step 1) and put them in the insect cages to raise the adult mole beetle, and place 2 pots of corn seedlings to lure the mole mole. Worms lay eggs, every 2 days, change the food;

[0094] The three plants of wheat aphid, sorghum aphid and corn aphid are placed in insect cages according to the ratio of 2:1:1.

[0095] The seedling tray is a planted host plant with aphids;

[0096] ②Collection of eggs

[0097] The newly hatched adult beetles start to lay eggs 6 days after eating, and collect eggs every 3 days thereafter;

[0098] The des...

Abstract

The invention relates to a method for large-quantity propylea japonica indoor raising. Wheat aphids, melanaphis sacchari and corn leaf aphids are used as aphids for feeding propylea japonica, and through specific technical measures such as host young aphid cultivating, aphid expanding propagation and propylea japonica artificial feeding, a large quantity of field-preventing and indoor-theory-study propylea japonica is obtained by expanding propagation. According to the method, wheat aphid feeding is carried out at a larval phase, and wheat aphid, melanaphis sacchari and corn leaf aphid feeding is carried out at an adult spawning period. The nutritional requirements of propylea japonica are improved, and the fecundity of propylea japonica is greatly improved. During raising, corn seedlings are placed, the habitat of propylea japonica is enlarged, space complexity is improved, propylea japonica autotomy and competition are lowered, and raising density can be greatly improved. The method is summarized according to the habit of propylea japonica and is easy to operate, economical and practical. Propylea japonica obtained by expanding propagation is high in survival rate and high in fecundity, and large-scale artificial breeding of propylea japonica can be achieved.

Description

technical field [0001] The present invention relates to the field of disease and insect pest control and the field of insect breeding, in particular to a method for indoor artificial large-scale breeding of ladybugs. Background technique [0002] The turtle-printed ladybug (Propylea japonica) is an excellent predatory natural enemy insect, and it is the dominant ladybug natural enemy in farmland ecosystems in North China, Northeast China and East China. For a variety of aphids on various crops, vegetables, fruit trees and forest trees, eggs of certain Lepidoptera and Homoptera insects, young larvae (nymphs) and cotton red spiders, psyllid adults, planthopper nymphs and black pine dry scales It has a good control effect on many kinds of pests. At the same time, the tortoise beetle has strong adaptability, strong drug resistance and high temperature resistance, and is a natural enemy insect with application prospects. In addition, at home and abroad, more and more attention ...
