Spray once every 7 days and spray 3~4 times. 2. Liriomyza Liriomyza sativae is an increasingly serious pest in cherry tomato production in recent years. Adults use an ovipositor to suck juice. The larvae sneak into the leaves or petioles to eat up the leaves.

Control methods: Arranging mouthwashes, eating and non-food-like crops in rotation; planting the pastoral areas in time; using yellow plates to kill L. sativae. Chemical control: When sporadic discovery occurs, the leaves of the insects are buried and then the drugs are sprayed. The spraying should be carried out when the road is 2 cm below the pest. In the morning or in the evening, a serial spraying method is used, spraying once every 7 days, and changing medications to delay the insects' resistance to various pesticides. Select insecticides with systemic absorption and contact killing effects, such as 1.8% agardine emulsifiable concentrate 2000~3000 times; or 98% Bataan original powder 2000 times; or 40% fly larvae emulsifiable concentrate 2000 times; or 40% green Vegetable treasure EC 1000 ~ 1500 times; or 2.5% Kung Fu EC 1000 times.
