The use of the phototaxis of insect pests to trap and kill insect pests has been widely demonstrated in the technical field of insecticidal lamps. The use of different light and wavelength insecticidal lamps for pest killing is very different. Each insecticidal lamp The manufacturers all say that their insecticidal lamps are effective, and they need to be tested through facts to better reflect them. A comparison experiment of application effects of solar multi-purpose insecticidal lamps and insecticidal lamps was conducted at Daqingzao Base in Taiwan. The results are as follows.

The Taiwan Daqingzao base was tested on an area of ​​16.7ha with 13.3ha contiguously. There is a 1.4ha-independent Taiwan Daqing jujube orchard from 500m away. It was planted in 2001, and Daqing dates were harvested before the end of March. Shrink trimming, leaving 2 to 3 primary branches of each direction in different directions as the main branch, 60 to 80 cm above the ground, and the rest are all cut off. The height of the tree in July is about 1.5m, and the canopy is about 2m. During the trial comparison period, the lights are turned on at 19:00 every day, and the lights are turned off at 6:00 the next day. The lights are not turned on at rainy nights, and the day is not included in the day. Install the above-mentioned xenon lamp at 13.3ha Taiwan Daqingzao base, the distance between the lamps is about 100m, the height of the lamp is 2.5m above the ground, and the lamps are not hung in the 1.4ha independent Taiwan Daqing jujube orchard. As a control zone, the hanging lamp mode is single. Column hangers. Solar multi-purpose insecticidal lamp in Taiwan Daqing dates application, greatly reducing the number of spraying, basically do not need to spray pesticides to control pests, to achieve the purpose of pollution-free fruit production. The single lamp control range is about 3.3ha, and the height of the lamp is 0.5m from the top of the crown.
Compared with the other three kinds of lamps, the solar multi-purpose insecticidal lamp and the different brand insecticidal lamp had fewer failures in comparison tests of Taiwan's Daqing jujube 55d. The other three kinds of lamps replaced the parts with frequent failures, and the high-voltage network cables of the frequency-vibrating lamps. It is horizontally wound and relatively compact, and the insect nets are rarely escaped. The other three types of lights have high-voltage network cables that are vertically arranged with wide intervals. After the insects touch the net, a considerable part of them can still escape. One of the important reasons why the total amount of pests is much more than the other three types of lamps.
