摘　　要：【目的】在室内、温室和露地3种条件下,通过测定烟蓟马(Thrips tabaci)对不同单色光及不同波长诱虫色板的行为反应,探究对烟蓟马具有最佳趋性的波长、光照强度,以及相关影响因子如性别、日节律、饥饿、温度、相对湿度对烟蓟马趋光行为的影响,为改进诱虫色板及诱虫灯等烟蓟马绿色防控技术和产品提供依据。【方法】首先,室内使用分辨率高、光谱测量范围广、稳定性好的单色仪测试装置测定烟蓟马对10种单色光的行为学趋性,筛选出烟蓟马趋性较强的单色光,并将初始光照强度通过中性密度滤光片衰减,探究光照强度对烟蓟马趋光行为的影响。其次,以烟蓟马趋光率为统计指标,探究性别、日节律、饥饿、温度、相对湿度对烟蓟马趋光行为的影响。根据室内试验结果,利用Dan Bruton虚拟波长及RGB值的函数关系,打印出相应波长的蓝色和黄色诱虫色板,涂胶制板。评价温室和露地条件下,烟蓟马对不同波长自制色板及不同厂家生产色板的趋性。【结果】室内试验结果显示,烟蓟马对450 nm的蓝色光趋性最强,趋光率高达75.34%,其次为562 nm的黄色光以及430 nm的蓝紫色光,趋光率分别为73.61%和64.03%。在430、450、562 nm单色光刺激下,烟蓟马雌虫的趋光性均强于雄虫。光强衰减试验结果表明,随着光照强度增加,烟蓟马趋性增强。在上午8:30—10:00时,烟蓟马对430、450、562 nm单色光最为敏感。饥饿4 h后,烟蓟马的趋光性最强,之后随着饥饿时间的延长,趋光性降低。温度为25—30℃时,烟蓟马对3种单色光趋性极显著高于对照组;15℃时,烟蓟马对单色光的刺激均不敏感。相对湿度为45%—60%时,烟蓟马对430、450、562 nm单色光的趋性均显著强于对照组,而在相对湿度为30%和90%时,烟蓟马对单色光的趋性与对照组均无显著差异。通过在温室和露地中应用不同波长色板及不同厂家生产的�【Objective】 The objective of this study is to explore the optimum light wavelength, light intensity and related factors, such as sex, daily rhythm, starvation time, temperature and relative humidity of Thrips tabaci through behavioral responses study under the different conditions of laboratory, greenhouse and field, and to provide a theoretical support for improving the control techniques and products of T. tabaci, such as color sticky cards and light traps.【Method】 Firstly, the behavioral responses of T. tabaci to 10 different wavelengths of monochromatic light were conducted by using monochromator testing device with high resolution, wide spectrum measurement range and high stability under laboratory condition. Monochromatic light with high response rate was screened and the initial light intensity was attenuated by neutral density filter to explore the effect of light intensity on the behavioral responses of T. tabaci. Secondly, the effects of sex, daily rhythm, starvation time, temperature and relative humidity on phototaxis of T. tabaci were also examined by using the rate of phototaxis as statistical index. Based on laboratory experiments, using the relationship between Dan Bruton’s virtual wavelength and RGB values, the blue and yellow sticky cards of the corresponding wavelengths were printed and the plates were glued. The tendency of T. tabaci to the self-made sticky cards of different wavelengths and sticky cards produced by different manufacturers was evaluated in the greenhouse and in the open field.【Result】The results of laboratory experiment showed that phototaxis behavioral response rate was the highest on blue light at 450 nm, and the rate of photaxis was as high as 75.34%, followed by the yellow light at 562 nm and the blue-purple light at 430 nm, the rate of photaxis was 73.61% and 64.03%, respectively. Under the stimulation of 430, 450 and 562 nm monochromatic light, the phototaxis rate of female T. tabaci was higher than that of male. The light intensity attenuation test of the
