海南益智传粉昆虫及其访花行为的初步研究

An observation on Pollinating Insect and their flower-visiting behavior on Alpinia oxyphylla Miquel

对海南省种植的益智访花昆虫种类、访花频次、时间及访花行为进行了初步研究。结果表明,益智访花昆虫有4个目(膜翅目、双翅目、鞘翅目、鳞翅目),7个科,13种昆虫,根据其访花频次及访花行为的观察,明确中华蜜蜂和大蜜蜂为益智的主要传粉昆虫。日活动规律观察表明,中华蜜蜂属于双峰型,访花高峰为9:00～9:30和16:00～16:30;大蜜蜂属于单峰型,访花高峰在13:00～13:30。

Pollinating insects of Alpinia oxyphylla in Hainan province were studied. A preliminary observation wase con ducted about the speices, visiting frequeney, staying time and behavior. Altogether 13 species, 7 families and 4 orders (Hyme nopt era, Diptera, Coleoptera and Lepidoptera) were found. Apis cerana Fabricius and Apis dorsata Fabricius were the most effective pollindtors due to their higher visiting frequencies and behavior. The observation of daily activity pattern showed that A cerana belong to the bimodal type, A.dorsata belongs to unimodal type, the peak of A. cerana pollination at 9: 00~9: 30 and 16: 00 ~16: 30 , the peak of A. dorsata pollination at 13: 00 ~13: 30.
