| 摘 要： | 【目的】研究荔枝蛀蒂虫光驱避防控技术在不同荔枝品种上的田间应用效果，以及对荔枝产量、品质和果园其他昆虫的影响，为荔枝蛀蒂虫绿色防控提供技术支持。【方法】2019—2020年，分别在广西钦州市钦北区、灵山县、浦北县和桂平市对三月红、妃子笑、桂味、鸡嘴、无核等早中晚熟荔枝品种开展荔枝蛀蒂虫光驱避防控技术田间试验，设光驱避（LED白灯，波长450~465 nm）、药剂防治和空白对照3个处理；2020年，同时在灵山县无核荔果园开展光驱避对果园其他昆虫的影响试验，设灯区（光驱避试验区）和暗区（药剂防治区）2个处理。【结果】光驱避对荔枝蛀蒂虫的防治效果为95.57%~100.00%，平均防治效果达98.50%；药剂防治对荔枝蛀蒂虫的防治效果为76.61%~100.00%，平均防治效果为93.24%，光驱避的防治效果比药剂防治高5.26%（绝对值）；光驱避的荔枝平均产量为11850.1 kg/ha，比药剂防治增产752.4 kg/ha。暗区捕获较多的昆虫有鳞翅目448头、半翅目181头和鞘翅目96头；灯区捕获较多的昆虫有鞘翅目269头和半翅目165头。【结论】光驱避防控技术通过人工光照破坏夜间的黑暗环境，可干扰荔枝蛀蒂虫成虫交配和产卵，使其不能产生后代而达到防治目的。该技术具有经济高效、绿色环保和操作简便的特点，可替代化学防治推广应用。

| Abstract: | 【Objective】To study the effect of light-repellent technology application on Conopomorpha sinensis in different varieties of Litchi，and to investigate the effect of fruit yield and quality of Litchi and other insects，so as to provide technical support for the ecofriendly prevention and control technology of C. sinensis.【Method】A field experiment was performed in 2019-2020 with 3 treatment groups，night-light treatment（white LED light，wavelength range of 450- 465 nm），insecticide treatment，blank control on early-，middle- and late-maturing varieties of Litchi such as Sanyuehong，Feizixiao，Guiwei，Jizui，and Wuhe in Qinbei District，Qinzhou City，Lingshan County，Pubei County and Guiping City，Guangxi，China. The effects on other insects using the light-repellent technology was studied with light treatments （light-repellent technology experiment areas）and no-light treatments（insecticide control and prevention areas）in Lingshan County，Guangxi in 2020.【Result】The results showed that the prevention and control effects of light-repellent technology of C. sinensis were in the range of 95.57%-100.00%，and the average control effect was 98.50%. Meanwhile，the insecticide control effects were in the range of 76.61%-100.00%，and the average control effect was 93.24%，indicating 5.26% （absolute value）lower than that of light-repellent technology. The average yield of Litchi in the light-repellent technology areas was 11850.1 kg/ha，which was 752.4 kg/ha more than insecticide control under field conditions. There were 448 individuals of the Lepidoptera order，181 individuals of the Hemiptera order and 96 individuals of the Coleoptera order were collected in no-light treatments areas，269 individuals of the Coleoptera order and 165 individuals of the Hemiptera order were collected in light treatments areas.【Conclusion】The light-repellent technology can severely disturb the processes of mating and oviposition of C. sinensis through artificial light at night，and then the females will fail to produce offspring， achieving control and prevention effects. This technique is cost-effective，eco-friendly and easy to operate so it can be used as an alternatives to the use of chemical insecticides. |
