千年桐访花昆虫初步调查研究

Preliminary Survey on Flower-visiting Insects of Vernicia montana

于2019年4月设置3个样地对千年桐盛花期的访花昆虫进行调查。调查结果,采集到访花昆虫33种,隶属8目22科,分别为膜翅目、缨翅目、双翅目、鞘翅目、鳞翅目、半翅目、革翅目和蜘蛛目昆虫,其中:鳞翅目的种类最多,为11种,膜翅目种类次之,为8种,双翅目种类位居第三,为5种;采集到的访花昆虫数量排序为:膜翅目>缨翅目>鞘翅目>鳞翅目>其他昆虫,膜翅目是千年桐花期访花传粉的优势昆虫;千年桐4目主要访花昆虫日活动规律为:在上、下午均出现出勤峰值时段,下午峰值高于上午,且出勤峰值时段不完全吻合。

The three sample plots were set up to investigate the flower-visiting insects of Vernicia montana in April 2019.The results showed that 33 species were identified,belonging to 22 families and 8 orders,which were Hymenoptera with 8 species、Thysanoptera、Diptera with 5 species、Coleoptera、Lepidoptera with 11 species、Hemioptera、Demaptera and Araneida.The order of the quantity of flower visiting insects collected was Hymenoptera>Thysanoptera>Coleoptera>Lepidoptera>other insects.Hymenoptera was the dominant flower-visiting insects of Vernicia montana.The flower-visiting activities of 4 major insects peaked in the morning and afternoon.The peak in the afternoon was higher than that in the morning,and the peak time was not completely consistent.
