Also known as arch arch worms, tea worms are more harmful to autumn tea in September. The prevention measures are as follows:
1. The protection of natural enemies in tea gardens should minimize the number of medications used, reduce the amount of pesticides, protect natural parasitic and predatory natural enemies, and give full play to the control of natural natural enemies.
2. Virus-spraying tea worm nuclear polyhedrosis virus has a strong susceptibility rate to the larvae of Apochaera. In the 1st and 2nd instar larvae stage, the nuclear polyhedrosis virus of tea pod borer is sprayed, and the dosage per acre is 1 billion~ 5 billion polyhedra.
3. Light trapping and killing adult insects in the field by installing frequency-vibration insecticidal lamps in the field can reduce the occurrence of the next generation of larvae.
4. Manual killing For lighter pests and local hazards in the tea plantation, artificial killing can be performed in conjunction with the daily management of the tea plantation.
5. Put chickens on chickens and eat quails. Also eat larvae. During the larval period, the tea bushes vibrate, causing the larvae to droop and cause the birds to feed.
6. Control of Pesticides Pesticides should be strictly controlled according to prevention and control indicators. The prevention and control index of the tea plantation when it is put into production is 4,500 heads per mu. Appropriate application of pesticides in the 3rd instar larval stage. The spraying method is suitable for spraying with low-volume awnings. Pharmaceutics selection: organic tea garden or green food AA grade tea garden can use 2.5% rotenone 150-200 ml, or 0.36 matrine 50-75 ml, to prevent water spray. Green food grade A and pollution-free tea gardens can use 35% Sai Dan 80-100 ml, or 1% abamectin (20-25 ml per mu, should be used in cloudy or sunny evening) and other agents to water spray Prevention.
