摘　　要：利用行为学方法研究了光谱、光强对西花蓟马Frankliniella occidentalis(Pergande)雌成虫的趋、避光行为的影响。结果显示:(1)在340—605 nm波谱内14个波长其光谱趋光行为反应为多峰型,峰间主次较明显。趋光行为反应中,蓝绿区498—524 nm有一较宽峰,趋光率20.31%;其它各峰依大小次序分别位于紫光380 nm、蓝光440 nm;(2)避光行为反应中,蓝光440nm处略高,避光率17.19%;紫外340 nm处亦有一峰,避光率15.63%;(3)随光强增强其趋光反应率增大,白光、380 nm和524nm刺激时其光强趋光行为反应呈一倒"L"型式样,498 nm为峰型,440 nm时为一较缓的平直线型;光强最弱时仍均有一定趋光率,最强时均未出现高端平台;(4)随光强增强其避光反应率增大,440 nm为较平缓直线;340 nm刺激时为较缓波动线。结果表明:光谱对其趋光行为有很大影响,光强度的影响较大且影响大小与波长因素有关。The western flower thrip, Frankliniella occidentalis （Pergande） , is one of the most serious pests causing adverse effects on global crop production. Since 2003, F. occidentalis has been affecting the crop fields of several provinces in China. The selectivity of F. occiclentalis on colors has been reported to have significant differences. In the present paper, the phototaxis behavior of F. occiclentalis （Pergande） in response to spectral sensitivity and light intensity were investigated. The results were as follows ： （ 1 ） The spectral sensitivity response of phototaxis at 14 monochromatic light selected within the range of 340--605 nm occmTed in a curve with multiple peaks. The primary peak within the range of 498--524 nm （blue- green） is the highest response rate of phototaxis （20.31% ） ; the secondary peak at 380 nm （violet） is the highest response rate of phototaxis （ 19.06% ） ; and the rest of the peaks at 440 mn （blue） is the highest response rate of phototaxis （ 18.44% ）. （2） The spectral sensitivity response of photophobism at 14 monochromatic light selected within the range of 340-605 nm occurred in a curve with two peaks ： a peak at 440 nm （blue） is the highest response rate of photophobism （17.19%） , and another peak at 340 nm （ultraviolet） is the highest response rate of photophobism （15.63%）. （3） The same wavelengths of light intensity appeared in different intensities in different phototactic response rates. In the white lightand monochromatic light at 380 and 524 nm, the response rate of phototaxis is increasing together with the relative intensity of light ; the relative intensity of light appeared as curves with increasing L-shaped peaks, which is the maximum response rate in log0.0. At 498 nm, two peaks appeared in log4.5 and logo. 0 with the sharp having multiple peaks. At 440 nm, the response rate of phototaxis is slowly increasing together with the relative intensity of light, and the shape was. near a straight line displaying
