Light trapping. The use of adult phototaxis, trapping and killing tea garden pests, which has a good control of tea pests, is currently used for solar frequency vibration type insecticidal lamp. It has an excellent trapping effect on lepidoptera adults such as Chagao, and Erythropodoptera, which is a small green leafhopper. Studies have shown that there is a difference in the number of insect pests in tea gardens and non-trap tea gardens trapped by frequency-vibration insecticidal lamps, and the control effect is 81.4%. Therefore, the promotion of the use of insecticidal lamps to trap and kill pests in tea gardens not only has a significant effect of trapping and killing, but also reduces or avoids the pollution of the environment caused by the use of chemical pesticides, the killing of natural enemies, pest resistance, pesticide residues, and human and animal poisoning. The occurrence is worth applying and promoting in major tea regions. In addition, statistical analysis of the types and numbers of trapped and killed pests is also an important means for pest prediction and forecasting. Insect traps are installed in the field at an average density of 20 to 30 acres, and mountain tea gardens generally have 1 ton of sight.
Swatch seduce. Pests are used to seduce the preferential tropism of different colors, such as false eye small green leafhopper, tea leaf yellow, tea yellow thrips blue, etc. have strong tropism. In combination with smearing the corresponding sex pheromone on the swatches, the trapping effect was significantly improved. Therefore, at the appropriate time, the corresponding swatches are installed according to the types of pests in the tea plantation, which has a good effect of controlling the number of insects in tea gardens, and it is also one of the main measures for preventing and controlling pests in organic tea gardens. At the same time, statistical analysis of the number of insect heads on the swatches can be used as an auxiliary means for corresponding pest prediction and forecasting. The number of installations in the swatch tea garden is generally 20-30 pieces/mu.
Sex pheromone trap. Sex pheromone is widely used in pest control, especially for lepidopteran pest control. Compared with chemical control, sex pheromone attractant has strong pertinence, high sensitivity, safety, non-toxicity, no killing of natural enemies and no pollution. The environment is excellent. The sex pheromones currently used in Daejeon are known as tea worm sex pheromones, tea pheromone sex pheromones, etc. However, under the condition of high density of insect populations, the effect of sexual attractants may be limited. This is a common feature of sex pheromone control. Therefore, the control effect in the tea gardens where pests are outbreaks is unsatisfactory, and it should be combined with other non-pollution prevention methods to achieve the goal of reducing the density of insect populations.
