Problems solved by technology

Aphelinus mali (Hald) is the dominant parasitic wasp of the apple aphid, and has been successfully applied worldwide. However, so far, the artificial propagation of Aphelinus mali (Hald) mainly relies on apple trees, which has the disadvantages of complex operation and long production cycle of apple seedlings. , low number of bees, large space occupation, and impact on fruit tree yields, etc.

Embodiment 1

[0018] The selection of embodiment 1. host plant:

[0019] 1-year-old crabapple Malus prunifolia (Willd.) seedlings. (Fruit growers cultivate their own rootstock materials for grafting apple seedlings, which can be purchased at the nursery stock market or sowed and cultivated by themselves. If self-sowed and cultivated, the seeds must be treated before sowing to make them white before sowing.)

Embodiment 2

[0020] Embodiment 2. The cultivation and management of host plant:

[0021] Use a disposable plastic water cup (diameter 5.0cm, height 11.0cm), drill a drainage hole at the bottom, or use a small flowerpot of appropriate size to fill it with soil mixed with humus. When the crabapple seedlings grow to 7-8 leaves, they can be transplanted into cups (pots) for planting. During the transplanting period, the soil moisture content in the cups should be observed daily, and watered in time. When the temperature is high in summer, a sunshade net should be added for sun protection. Generally, 10- After about 15 days, the seedlings can survive and can be used for the mass reproduction of the apple aphid.

Embodiment 3

[0022] Embodiment 3: the relation of parasitic quantity and age of host

[0023] Prepare a certain number of insect-free crabapple seedlings in advance, and the cultivation method is as in Example 2. Connect 3 or 5 adult aphids to each crabapple seedling, let them colonize and produce nymphs for 2-3 days, and then remove the adult aphids , when the nymphs develop to the 1st, 2nd, 3rd, 4th instar and adult aphids, insert the begonia seedlings with insects into 1 pair of newly emerged Sunlight bees (one male and one female), with a diameter of 50.0cm, a height of The 80 mesh gauze cover of 30.0cm covers the crabapple seedlings. Place the insect cages containing crabapple seedlings and sun begonia in the incubator (temperature 24±1°C, light-dark ratio 14:10, RH60-70%), let the sun begonia parasitize for 48 hours and then remove the sunbeam adults, crabapple The apple cotton aphid on the seedlings continued to be raised, and when black pupae appeared on the branches, the number o...

Abstract

The invention provides a simple method for breeding aphelinus mali. The simple method is characterized by comprising steps of (1), providing annual malus prunifolia seedlings and planting the malus prunifolia seedlings in cups or pots when 7-8 leaves grow on each malus prunifolia seedling; (2) inoculating 3-5 adult eriosoma lanigerum on the planted malus prunifolia seedlings, placing the malus prunifolia seedlings with the eriosoma lanigerum into screen cages with a large quantity of aphelinus mali which is subjected to eclosion in advance when nymphs of the eriosoma lanigerum on branches of the malus prunifolia seedlings develop into fourth-stage eriosoma lanigerum or adult eriosoma lanigerum, enabling the aphelinus mali to perform parasitism on the malus prunifolia seedlings in the screen cages for 48 hours and then taking out the malus prunifolia seedlings; continuing feeding the eriosoma lanigerum on the malus prunifolia seedlings for 1-2 days after the eriosoma lanigerum turns black, trimming the branches of the malus prunifolia seedlings by pruning shears or brushing off black pupae by brushes. The simple method has the advantage that the aphelinus mali can be quickly and efficiently bred.

Description

technical field [0001] The invention relates to a method for rapidly multiplying the sunbee, a parasitic natural enemy of the apple cotton aphid, in particular to a process and method for rapidly multiplying the sunbee with crabapple seedlings. Background technique [0002] Apple cotton aphid Eriosoma lanigerum (Hausmann) is one of the pests subject to quarantine in my country. It is currently causing damage in major apple producing areas in China. It often gathers in the cut wounds of tree trunks, saw cuts, new shoot leaf axils and the rhizosphere of bare ground. It sucks sap and secretes in vitro digestive juice at the same time, stimulates the tissue proliferation of the affected part of the fruit tree, forms tumors, and affects nutrient delivery. It is an important pest in apple production. [0003] At present, as people's requirements for the quality of agricultural products are increasing day by day, biological control technology is one of the important ways to reduce t...
