Foraging and pollination insects of Paeonia lactiflora

20 0 0～ 2 0 0 2年对内蒙古赤峰市高格斯台罕乌拉自然保护区内野生芍药 (PaeonialactifloraPall.)和内蒙古农校芍药园内栽培品种芍药的访花昆虫进行调查 ,经整理鉴定有 2 9种 ,自然保护区内芍药的访花昆虫种类有 1 7种 ,芍药园内的访花昆虫有 1 7种。根据传粉行为和数量的比较确定了自然保护区内主要传粉昆虫为丽斑芫菁、黄胫宽花天牛、黑胫宽花天牛、短毛斑金龟、饥星花金龟、白星花金龟和大淡脉隧蜂 ;芍药园内的主要传粉昆虫为意大利蜜蜂、棕边管食蚜蝇、长尾管食蚜蝇、大淡脉隧蜂、灰带管食蚜蝇和小淡脉隧蜂。

From 2000 to 2002, we investigated foraging insects in the wild Paeonia lactiflora Pall.in the nature reserve of Gaogesitaihanwula. and the cultivated P. lactiflor in the yard of the Inner Mongolia Specialized School of Agriculture. We found that the total number of foraging insect species was twenty|nine. Seventeen insect species foraged in wild P. lactiflora, and seventeen species foraged in cultivated P. lactiflora. By comparing the pollination behavior and the number of pollination insects, we found that the main pollinating insects for wild P. lactiflora included Mylabris speoiosa Pallas,Euodinus bifasciatus (Olivier),Euodinus interrogationis (L.),Lasiotrichius succinctus (Pallas,1781),Potosia brevitarsis Lewis and Lasioglossum sp-1; the dominent pollinators for the cultivated P. lactiflora included Apis mellifera L.,Eristalis tenax (L.),Eristalis arbustorum (L.),Lasioglossum sp1,Eristalis cerealis Fabricius and Lasioglossum sp-2.
