摘  要:
2007—2009年,对明亮长脚金龟Hoplia spectabilis Medvedev生物学特性进行了调查研究。明亮长脚金龟是青海省天峻县危害沙棘Hippophae neurocarpa的主要害虫,1 a发生1代,以2~3龄幼虫在60 cm以下土壤中越冬。翌年5月下旬至6月上旬老熟幼虫开始陆续筑蛹室化蛹,蛹期10 d左右。6月中旬成虫开始羽化出土,6月下旬至7月上旬气温达到11.4℃时为出土盛期。成虫每日的活动危害期集中在12—14时,群聚于树上啃食叶片、花朵和果肉等。成虫具假死性,无趋光性,雌雄比1.6∶1。此外,针对该虫生物学特性及发生危害特点提出了相关防治建议。

摘  要:
Hoplia spectabilis was a major pest insect infesting Hippophae neurocarpa in Tianjun County,Qinghai Province.It had one generation a year and overwintered as the 2nd-3rd instar larvae in the soil 60 cm below the ground.The mature larvae began to pupate between the late May and early June the next year.In mid-June,the adults began to emerge with a peak from the late June to early July when the temperature reached about 11.4 ℃.Adults fed on leaves,flowers and fruits of Hippophae trees,causing severe damages to the bushes.The adults were thanatosis and show no phtotaxis.The ratio of female to male was 1.6∶1.Control measures against the pest insect were discussed.
