The genus Liriomyza is a member of the genus Liriomyza (Lepidoptera:Lepidoptera:Lepidoptera:Diptera), which is mainly composed of the leaf juice and mesophyll between the epidermis and the epidermis of the larvae. After tunnelling on the leaves, leaves form a tunnel, and the tunnel twists and turns, there is no certain direction, forming a gray stripe pattern, causing damage to beans, eggplant, sponge gourd and other vegetables, seriously affecting the normal growth and development of vegetables. In the high-flying season of Liriomyza spp., early detection, early prevention and control, and harm reduction are needed to avoid unnecessary economic losses to the vegetable farmers.
Control methods:
After agricultural crops are harvested, they can be deep-turned in time after they are harvested, which can reduce insect populations and reduce hazards. Using the phototaxis of Liriomyza sativae, black light can be used to trap and kill adult worms. The mixture of oil and butter is applied on the yellow plate, inserted into the field, and the sticky flying adults are inserted into the yellow plate 20-30 pieces per mu.
Pharmaceutics control Because of the damage of leaf latent larvae, it is necessary to make predictions and predictions of insect pests, and to prevent and control the critical period from the spawning period to the initial stage of hatching. 48% Rospar Emulsion 1000x, 20% Lithosperm Pore Emulsion 3000x, 2.5% Kung Fu Emulsion 2000-3000x, 1.8% Avermectin Emulsion 3000x, 75% Lac 5000x , 5% Rui Jin special suspension 1000 times. For the characteristics of larvae feeding juice and mesophyll, 500 times the anti-flood solution can be added to the liquid (Delipping, killing and killing), and appropriate amount of white wine can also be added to improve the efficacy. In order to prevent drug resistance, the above pesticides should be used interchangeably.
