摘要
研究昆虫对不同光强光源的行为反应,有利于确定诱集光源的功率、诱集有效空间范围及布点密度,为此,利用昆虫视觉行为学研究方法,研究华山松木蠹象优势寄生蜂——松蠹狄金小蜂对不同光强敏感单色光的趋向行为。结果表明,无论从趋向率还是趋向位移看,3种敏感单色光(340nm紫外光、415 nm紫色光和549 nm黄绿光)下,松蠹狄金小蜂的趋光行为与光强具有明显相关性,光强较低时呈正相关,光强较高时呈负相关,在415 nm紫色光和549 nm黄绿光下,松蠹狄金小蜂的趋光行为反应随着光强的继续增加稍有减弱,而在340 nm紫外光下,松蠹狄金小蜂的趋光行为反应随着光强的继续增加明显降低,甚至低于光强较低时的水平。3种敏感单色光中,松蠹狄金小蜂的趋光行为反应达到峰值时光强的大小顺序为:黄绿光(549 nm)>紫色光(415 nm)>紫外光(340 nm)。
Studying behavioral response of insects to different light intensity could help to determine the power, effective trapping range and distribution density of trapping lights. This study dealt with the visual behavioral response of Dinotiscus armandi,which is a major natural parasitic wasp of Pissodes punctatus, under different light intensity of its three kinds of sensitive monochromatic lights （549 nm yellow-green light,415 nm purple light,and 340 nm UV light）. The results demonstrated that the phototactie behavior of D. armandi was significantly correlated with light intensity according to the indexes of trending rate and trending displacement, and it showed positive correlation when light intensity was low, it showed negative correlation when light intensity was high. Furthermore in the UV （340 nm） , the phototactic behavior of D. armandi abidingly weakened as light intensity increased, even weaker than that at the low light intensity. Under the three sensitive monochromatic lights, the light intensity causing the maximum of phototactic re- sponse of D. armandi was in the following order： yellow-green （549 nm） 〉 purple （415 nm） 〉 UV light （340 nm）.
