适配太阳能诱虫器诱杀柑橘木虱LED光源的筛选

Screening of LED light source of the adapter solar trap lamp for trapping the citrus psyllid

柑橘木虱(Diaphorina citri)是柑橘黄龙病的传播媒介。为达到治虫防病的目的,在室内利用昆虫行为反应器开展适配太阳能诱虫器的LED光源筛选,结果表明:柑橘木虱成虫对光照强度分别为1 800lx和4 310lx的蓝光和绿光(波长分别为460nm和531nm)在光照时长为17h时的趋光性最佳,相同波长条件下,其趋光性与光照强度和光照时长成正相关。该研究结果为进一步探索适宜田间柑橘木虱测报和高效诱杀的LED光源提供理论依据。

The citrus psyllid is the vector of Huanglongbing. In order to control citrus psyllid and prevent disease, screening of LED light source adapter solar trap lamp for citrus psyllid by using reaction vessel of insect behavior was carried out in the laboratory. The results showed that the phototaxis of 1 800 Ix and 4 310 Ix blue and green light sources （wavelength 460 nm and 531 nm） were best on the illumination duration of 17 h. It was also found that the phototaxis of citrus psyllid adults was positively correlated with light intensity and light duration under the same wavelength condition. It might provide an effective theoretical basis for the LED light source for forecasting and trapping citrus psyllid in the field in the future.
