| 摘 要： | 1989年于山东省平度市山楂园的定点调查和1988-1989年的室内外饲养观察表明：在田间，暗黑鳃金龟的成虫白天出土数量极少；夜间隔日出土的习性表现为—天数量多．一天数量少．即大小日现象；降雨对其出土没有影响。自然情况下。所有个体均隔日出土。对其出土习性，连续20天缺食没有影响；始终黑暗50天以上，影响不大；24小时光照和24小时黑暗的光周期．开始影响甚小，之后十分明显．再后影响又小；始终光照时，其规律完全被打破，出土数量也大大减少。由此推断，影响暗黑鳃金龟出土习性的主要因素是光照的持续时数，其临界光周期应在14至24小时之间。

| Abstract: | The investigation was carried out in the hawthorn orchards of Pingdu County in 1989together with the indoor and outdoor observation in Laiyang in 1988- 1989. The results indicat-ed that few adults of IIolotrich ia parallela Motschulsky could be found in the fields at daytime. They came out of the ground every two days at nights without influence on raining. Lacking offood continually for 20 days and staying at dark condition for more than 50 days. very little influ-ence occured on the adult habit of coming out of the ground.Contrary. the photoperiod showedimportant influence on the adult habit.The critical photoperiod may be within 14- 24 hours perday. |
