不同波长灯管应用于监测美国白蛾的研究

Fluorescent tube at different wavelength applied to study Hyphautria cunea Drury monitor technology

在北京市房山区窦店镇交道富恒果园设置了美国白蛾监测点,筛选和定制了9个不同波长的灯管进行监测美国白蛾的实验,以研究确定美国白蛾的敏感波长。试验结果表明:美国白蛾较为敏感的波段有335nm、345nm、351nm、362nm、368nm等,其中对351nm最为敏感。不同波长灯管诱捕到美国白蛾成虫雄虫数量远远高于雌虫数量。

Monitoring sites were set on Fuheng Orchard in Doudian Town Fangshan District, and 9 kinds fouorescent tube at different wavelength were selected to monitor Hyphautria cunea（Drury）. The results showed that the sensitive wavelength of H. cunea were 335 nm, 345 nm, 351 nm, 362 nm and 368nm. The most sensitive wavelength was 351 nm. The adults of H, cunea caught were predominantly male.
