Pay attention to control greenhouse watermelon locust

In recent years, watermelon locusts in greenhouses such as Rugao have become more common. Not only do they directly suck juice causing serious water loss and malnutrition, but they also cause coal pollution and virus diseases. It is difficult to form 1-2 batches of melon after harvesting. The output has become the main pest influencing the production of watermelons, and prevention and control should be carried out in time. Physical control Hanging silver-gray plastic strips in the vents of greenhouses can avoid aphids and significantly reduce the amount of maggots. Placing 40-45 mesh silver-gray or white insect nets at the gates and vents can prevent locusts from entering the shed. Using the winged crickets to yellow tropism, trapped with a yellow plate. Chemical control: 10% imidacloprid wettable powder 2000 times, or 20% fenpropathrin EC 2000 times, or 50% anti-inferior wettable powder 2500 times, or 10% nicotine EC 500 to 1000 times spray Prevention. Aphid breeding ability is strong, there are many generations, it is easy to produce drug resistance, pay attention to alternate rotation of medication. Aphids are generally concentrated on the heads, tender leaves, young stems, and dorsal parts of the melon seedlings. The application of these parts should be emphasized. Closed canopy with good sealing effect can be used to close the shed in the evening, and use 10% dichlorvos smoke agent to prevent smoke from 400 to 500 grams per acre. The next morning, it should be ventilated and ventilated. In the early stage of the locust infestation, it is smoked once every 6 to 7 days, and continuously smoked 2 to 3 times.
