Method for controlling phototaxis insect pests for tea trees

Abstract

The invention provides a method for controlling phototaxis insect pests for tea trees. The method includes setting independent small tea garden pieces in tea gardens to be used as temporary habitats for lamp-trapped insects, mounting trap lamps in the small tea garden pieces, trapping the insect pests in the temporary habitats for the lamp-trapped insects and then allowing the insect pests to naturally inhabit in tea tree groves; controlling the insect pests in the temporary habitats for the lamp-trapped insects by an artificial control process, a biological control process or a chemical control process according to egg attaching and egg hatching conditions of the insect pests in the temporary habitats for the lamp-trapped insects. Non-target insects can be effectively prevented from being killed, and the method has the advantages of low energy consumption and cost.

Description

technical field [0001] The invention belongs to the field of agricultural insecticide, in particular to a method for preventing and controlling tea tree phototaxis pests. Background technique [0002] Humans discovered the phototaxis of insects a long time ago, and the use of insecticidal lamps to control pests is an important physical control measure. With the advancement of science and technology and the needs of production, researchers have further improved the functions of insecticidal lamps, adding supporting functions such as light control and insecticidal grids; , lamp density and other technical parameters have improved the species and quantity of insects trapped by insecticidal lamps, and the efficiency of trapping and killing has been improved. After the implementation of standardized production certification of tea in my country, the application of insecticidal lamps has continued to increase. The insecticidal lamp mainly includes a power supply device, a light ...

AI Technical Summary

Problems solved by technology

The shortcoming of above-mentioned control method is:

[0003] 1. There are many kinds of predatory natural enemies in tea gardens, which are widely distributed, large in number, and long in duration, and have a significant control effect on pests in tea gardens. However, the above methods have poor selectivity and eliminate both phototactic insects, both pests and beneficial insects. The protection and utilization of predatory natural enemies cannot exert the control effect of predatory natural enemies on pests, which seriously damages the ecosystem of tea gardens

[0004] 2. The structure of the insecticidal lamp used is complex, difficult to maintain, and has a short service life

At present, the basic structure of most types of insecticidal lamps generally includes insect-attracting light sources, insect-killing components, insect-collecting components, protection components, support components, etc. The overall structure and circuit system are complex, and the more complex the system, the higher the failure rate, especially in the rainy season. It is often difficult for the rain control system to work normally, resulting in damage to the lamp body; especially the insecticidal components usually use high-voltage insecticidal methods, including step-up transformers, circuit systems and insecticidal nets, which will consume a lot of power, which will inevitably reduce the use time of solar cells and Service life; power grids and insect collection components need to spend a lot of time cleaning and maintenance, otherwise the insecticidal effect and service life will be seriously affected; in addition, the use of high-voltage power grids also increases insecurity

[0005] 3. The cost of insecticidal lamps used is high, and the one-time investment is large, so it is not easy to promote

Due to the complex structure, the overall cost has risen, which has exceeded the psychological price of ordinary tea enterprises. Currently, it is only used locally in a few bases.
