What are the key points of controlling tea seed weevil?

(1) Artificial killing: By using the suspended animation of adults, plastic films are laid on the ground during the peak of adult occurrence, and adults are killed by vibration. (2) Farming in tea garden: In July and August, ploughing, hoeing, shallow ploughing and deep ploughing in tea garden can obviously affect the burial of newly hatched larvae and the survival of subsequent larvae, and its control effect can reach 50%. (3) Biological control: Beauveria bassiana 87 1 powder can be selected, mixed with fine soil every 667m2 1 ~ 2kg and sprinkled on the soil surface. (4) Chemical control: For green food tea gardens and low residue tea gardens, the number of insects per hectare should be above150,000, and adults should be sprayed with 98% wettable powder of cartap and 2.5% bifenthrin emulsifiable concentrate of 3,000-6,000 times at flowering stage. Ordinary tea gardens can be sprayed with 1000 times fenthion emulsifiable concentrate.
