Electrophysiological methods were used to test the visual sensitivity of European grapevine moth, Lobesia botrana (Lepidoptera: Tortricidae) to wavelengths ranging from 300 to 700 nm. For male and females tested, a main, peak response occurred in the 460-540 nm range (blue-green wavelengths) with females having a generally lower response to wavelengths in that range. A second smaller peak was observed for both sexes at the 340-420 nm range. A general linear model indicated that males, virgin females, and mated females did not react differently to changes in wavelength. No moths showed any obvious sensitivity to wavelengths between 580 and 700 nm. Based on our retinal recording data we suggest that UV light traps (≤480 nm) could be utilized alongside pheromone traps when monitoring L. botrana in high risk areas.
采用电生理学方法测试了欧洲葡萄蛀蛾（鳞翅目：卷蛾科）对 300 至 700nm 波长范围的视觉敏感度。对于测试的雄性和雌性个体，在 460-540nm 范围内（蓝绿光波长）出现了主要的峰值反应，而雌性对该范围内的波长的反应通常较低。两性在 340-420nm 范围内观察到第二个较小的峰值。一般线性模型表明，雄性、处女雌性和交配后的雌性对波长的变化没有不同的反应。没有昆虫对 580 至 700nm 之间的波长表现出明显的敏感性。根据我们的视网膜记录数据，我们建议在高风险地区监测 L. botrana 时，可以将紫外线诱捕器（≤480nm）与信息素诱捕器一起使用。
