Please introduce Liriomyza huidobrensis, which belongs to the genus Liriomyza huidobrensis, which mainly uses larvae to eat the sap and mesophyll between the upper and lower epidermis of plant leaves, forming nearly circular pitted maculae on the leaves, and the larvae feed on the leaves to form tunnels and tunnel curves.

How to control Liriomyza huidobrensis by planting beans? Please introduce the genus Liriomyza huidobrensis, which belongs to the genus Liriomyza huidobrensis. The insect mainly uses larvae to feed on the sap and mesophyll between the upper and lower epidermis of plant leaves, forming nearly circular pitted maculae on the leaves, and the larvae form a tunnel after eating mesophyll on the leaves. The tunnel twists and turns without a certain direction, forming a pattern of gray-white stripes, causing damage to beans, eggplant, towel gourd and other vegetables. Seriously affect the normal growth and development of vegetables. In the high incidence season of Liriomyza huidobrensis, it is necessary to detect, control and reduce the harm as early as possible, so as to avoid unnecessary economic losses to vegetable farmers. Prevention and control methods: 1. Agricultural prevention and control. After the previous crop is harvested, turning deeply in time can reduce the insect population and reduce the harm. Making use of the phototaxis of Liriomyza huidobrensis, the adults can be killed by black light, mixed with oil and butter on the yellow plate, inserted into the field, stick to the flying adults, insert 20 pieces of yellow plate per mu. two。 Chemical control. Due to the harm of Liriomyza huidobrensis larvae, it is necessary to make a good prediction of the insect situation and grasp the critical period from the peak spawning period to the early hatching stage as early as possible. You can choose 48% Lesbon EC 1000 times, 20% Liriomyza Bao EC 3000 times, 2.5% Kung Fu EC 2000 times 3000 times, 1.8% avermectin EC 3000 times, 75% Qianke 5000 times, 5% Regent 1000 times. According to the characteristics of larvae feeding on juice and mesophyll, 500 times anti-disease liquid (damaging Lipin, killing insects) and appropriate amount of liquor can be added to the medicine solution to improve the efficacy. In order to prevent the development of drug resistance, the above pesticides should be used alternately. Click to get more bean planting techniques click to get more vegetable planting techniques
