Tomato leaf miner moth mainly harms tomatoes, but can also harm eggplant, potato, ginseng fruit, tobacco and other crops. It is expected that the overall occurrence in 2024 will be moderate, and the occurrence of tomato plots in some areas will be more serious, and the peak period of damage will occur from flowering to fruit ripening.
Insect net barrier. The entrance of the seedling shed and the production shed is equipped with a double-layer curtain of 60 mesh insect-proof nets, and the vents are equipped with insect-proof nets to effectively prevent the adult tomato leafminer moth from entering the shed.
Light booby-trap. During the occurrence period of adult worms, insecticidal lamps are set up in contiguous planting fields, 1 lamp is set up every 5-10 mu in open field, 1 lamp is set up in each shed in protected land, the light source is 0.5-1.0 meters above the ground, and the insect collection device is appropriately added with water containing 0.2% washing liquid.
Ecstasy interferes with mating. Before the tomato seedlings are planted, place the vain silk or vain tube (60 per mu) in the field, or the intelligent jet type mating interference release device (1 set per 3-5 mu), which is suitable for continuous use, and is placed in a dense outer and sparse inside, with a height of 10-20 cm from the ground.
Sexual trapping kills. Sexual traps are set up in contiguous planting fields to trap and kill adults. Triangle or wing-shaped viscose traps are used for open-field tomatoes, 8-10 are placed per mu, and the bottom of the traps is 10-20 cm from the ground.
Take advantage of natural predators. Honey-based plants such as calendula, sesame, buckwheat and bitter buckwheat should be planted at the edge of the field or beside the ditch to conserve natural enemies, and the use of broad-spectrum pesticides should be avoided, and spot and precision medicine should be promoted.
Unleash natural enemy insects. Adults can be detected in the field to release parasitic natural enemies such as yellow-eyed wasps and short-barreled red-eyed wasps, or predatory natural enemies such as small-flowered bugs and bugs.
Spraying should be done 5-8 days after a sudden increase in the number of adults (3-5 times more than the previous day) or at the first sight of larval lurks. It is recommended to spray in the afternoon (after sunset) on non-rainy days, once every 7-10 days, to spray evenly and thoroughly, especially on the front and back of the middle and upper leaves. Pesticides that can be used include Bacillus thuringiensis G033A, Beauveria bassiana coccidioi, and ethylspinosad. Pay attention to the rotation of medications, and strictly enforce the safe interval between the use of drugs.
