With the continuous expansion of the agricultural area of the facility, the suitable temperature in the greenhouse and the tender vegetables provide very suitable conditions for the survival and reproduction of pests, and the greenhouse whitefly, as a common pest, has become more and more serious in recent years, and the resistance to chemical pesticides has become stronger and stronger, and the prevention and control has become more and more difficult.
There are two types of whitefly in greenhouses: greenhouse whiteflies and whiteflies. They are very small individuals, but the population is large, the reproductive ability is strong, the adult insects have wings, can suck a lot of leaf juice, form yellow spots and even make the whole leaf yellow, the plant wilts or dies, and the whitefly can spread a variety of viral diseases.
Traditional agriculture mostly uses chemical pesticides to control whiteflies. The operation process will produce great pesticide waste and poor control effect, and insect pests are prone to drug resistance. In addition, the "pesticide residue" on the crop is a major problem for the majority of consumers, especially like tomatoes, cucumbers can directly import raw vegetables and fruits, so the use of pesticides is a lot of taboos.
Isn't there a more economical, more effective, and more harmless way? Of course.
The use of natural enemies of pests to control pests is the most ideal biological control technology and an important part of ecological agriculture. Lily aphid wasp is a parasitic wasp widely commercialized in the world for controlling greenhouse crop whitefed, mainly used to control whitefly and whitefly on greenhouse tomatoes, peppers, bell peppers, eggplants, cucumbers and other vegetables.
When whiteflies or crops have been colonized for a week in the greenhouse, they begin to release aphid wasps. When used, hang the bee card directly on the branches in the upper middle part of the plant. The wasps automatically look for whiteflies and parasitize nymphs of whiteflies.
The aphid wasp looks for the affected crop through the visual and taste senses, lays its eggs in the body of the whitefly nymph, grows by eating the body fluids of the whitefly nymph, and completes the development from larva to pupa in its body, thus killing the whitefly nymph, and the whitefly nymph after being killed gradually turns black. After about ten days of growth and development in its body, lice xiaofeng pupates into adult worms, and then breaks out of the cocoon of the whitefly nymph, and then looks for new whitefly to lay eggs and reproduce, and so on, so as to achieve the purpose of preventing and controlling greenhouse whitefed.
The above is an introduction to the use of aphid wasps to control whitefly, if you are currently helpless to control greenhouse whitefly, you may wish to try the aphid wasp.
