Problems solved by technology

[0002] Aphids, commonly known as greasy insects, belong to a class of harmful insects in the order Homoptera. Because they like to parasitize on the seedlings, young leaves, and stems of various plants, and use their mouthparts to suck plant juices as food, the host plants are severely deprived of water, nutrition, the leaves shrivel, wither, and eventually die; in addition, viruses can be transmitted, causing viral diseases, and aphids have extremely high fecundity, and if they are not prevented and controlled in time, they will seriously endanger the normal growth and development of crops and cause losses
In order to control aphids, people widely use insecticides. While effectively killing aphids, it will also cause pesticide residues, affect the quality of crop products, and endanger people's health.
In nature, aphids also have some natural enemies, such as hoverfly, which is one of them. Adult flies or larvae will prey on aphids in large quantities. As long as a certain number of fly population density is reached, the damage of aphids to crops can be effectively prevented. It can also avoid the problem of pesticide residues, but the natural hoverflies are restricted by the natural environment, and the number is limited, which cannot meet people's needs for aphid control

Embodiment 1

[0020] Use bamboo, wood or steel as columns, beams and arches to build a scaffolding, and then cover with plastic film, shade net and plastic gauze net to build three greenhouses: length × width × height 6 × 2.5 × 2m Aphid shed, divided into 3 rooms by plastic gauze; 3×2.5×2m seeding shed, divided into 2 rooms by plastic gauze; 9×2.5×2m expanded fly shed; put flower pots with a diameter of 30cm and a height of 25cm The nutrient soil prepared by 70% of paddy field soil, 25% of farmyard manure, 3.5% of oil rot and 1.5% of compound fertilizer is used to plant a Gastrodia elata seedling with a height of 10cm in each pot, and then move the flowerpot of the planted seedling into the shed for planting aphids and planting flies. Arrange the branches in the shed, pay attention to observe the seedlings, water and fertilize. There is a gap between each compartment of the potted seedlings in the shed, and the temperature, humidity, and light in the shed are adjusted to make the Gastrodia ...

Embodiment 2

[0022] Build a kind of aphid shed, a kind of fly shed and a fly expansion shed as described in Example 1, place a plurality of flower pots with a diameter of 30 cm and a height of 25 cm in the aphid shed and the kind of fly shed, arrange in rows, and put 60% of paddy field soil, 30% of farmyard manure, 5% of rapeseed, 4.5% of plant ash, 0.5% of calcium, magnesium, and phosphate fertilizers are used to prepare the nutritious soil. After 7 days, plant a sun-dried tobacco seedling with a height of 12cm in each pot. Pay attention to watering and fertilizing to make the seedlings grow vigorously. , when the tobacco plant grows to 6 leaves and 2 hearts, each plant is connected with 6 healthy and detoxified aphids, the temperature of the shed is controlled at 24-29°C, and the humidity is controlled at 40-45%, so that the aphids can reproduce as much as possible; in the fly expansion shed Arrange soil moisture into two rows, moisture height 15cm, moisture distance 100cm, transplant sun...

Abstract

The invention discloses a method for preventing and controlling aphids by breeding syrphidae and belongs to a biological control technology. The aphid preventing and controlling method comprises the following steps of planting aphid breeding crops in a greenhouse to breed aphids; then introducing the syrphidae from wild into the greenhouse; regulating and controlling the temperature and the humidity, and enabling the syrphidae to freely prey the aphids in the greenhouse, develop, grow and propagate on a large scale. When field crops encounter aphid damage, the batch syrphidae can be fed into a field for killing the aphids. The method is good in prevention and control effect, and low in consumption; no pesticide is used, and the problem of pesticide residue is solved, so the method is a better aphid controlling method.
