Diving flight is an important pest on vegetables. It mainly passes through the larvae to pass through the larvae, producing irregular worms, and some female detachment can also puncture the host blade and feeding, which not only affects the photosynthesis of the plant, but also seriously reduces the various types. Crop yields and even lead to uptake.

Several Typical Representatives of Diving Flies

1 invasive species include mainly American spotted fly, South American spotted fly, clover potential fly and tomato wilt.

What are the vegetable types, what happens, what's happening, and how can your farmers prevent treatment?

Differences in several invasive spots characterize latent flies

Note: from left to right, head, wing veins, genitalia genitalia are harmful and drawn from his yuping.

American Potour: Beacon, larvae may be harmful, adult insects in front of the blade, larvae, sneak into the blade and the blade of the leaf, emerges from the epidermis of the blade, usually does not pass through the leaf veins, Bliss branch, Bliss branch, Bean, Huche and Askiore, you can not help harmful undergraduate.

South American cosmetology: adult worm gum in leaves, larvae after hatching, larvae, lower skin, lower skin, wreaths, often bulk, incoherent, presenter of a wide range of, viko academy, huche, sakko, sasko, classic, and so on.

Tomato spots: adults in front of the blade, knocking leaf cells, larvae, larvae, deciduous leaves fall, worms can pass through the leaves with black struts. Hosts have a narrow range, mainly in cube crops.

Comprehensive prevention and control of latent

Agricultural precautions: clean fields, timely disposal of dead leaves, eradication of weeds, y embedded or fertilized, reduce the number of pendant feathers in vegetable fields; reasonable arrangement of the mouth, wearing non-food plant, remove the bridge to rest; garden after the harvest of vegetables, garden cultivation, the elimination of insects, and the protection of boring shed.

Physical prevention and treatment: laying an insect-proof network; hanging yellow boards or rubber strips formulated; light manual killing.

Biological prevention: protection and use of natural natural enemies, such as Yoshi Komori, Golden Mass, etc., facilities initially released.

Drug prevention: due to the overlap of generations, there is no obvious classification, it is recommended to apply peaks and larvae of the first application of 1?2 pellets, once in 7?10 days, 1 time to prevent 2?3 times. The drug of choice is milramide, thiazide and others.
