生态园访芍药花昆虫物种形态特征及访花行为

Species and Morphological Characteristics of Paeonia lactiflora Flower-visiting Insects from Ecological Garden

本文对山西省万柏林生态园内访芍药花昆虫进行调查,共鉴定出11种,隶属于双翅目食蚜蝇科、膜翅目蜜蜂科、隧蜂科、切叶蜂科和半翅目盲蝽科3个目5个科。其中,膜翅目的丰富度值为6,最高,占54. 55%。长尾管蚜蝇、短腹管蚜蝇和意大利蜜蜂的多度值较高。4—6月,意大利蜜蜂有3段时间访芍药花,是有效的传粉昆虫。5月22日,膜翅目的丰富度值最高,为6。双翅目多度值最多,为39。对11种访芍药昆虫的形态特征和访花行为进行了描述,相同科物种访花行为相似。

The flower-visiting insects of Paeonia lactiflora from Wanbailin Ecological Garden in Shanxi Province were investigated. 11 species belonging to 3 orders such as Hymenoptera,Diptera,Hemiptera,and 5 families such as Syrphidae,Apidae,Halictidae,Megachilidae,Miridae. Hymenoptera had the highest richness 6,which accounted for 54. 55 %. The Eristalis tenax,E. arbustorum and Apis mellifera lingustica possessed higher abundance than other species. A. m. lingustica visited the flower of P. lactiflora on 3 investigated time in April to June,which was effective pollinators. Hymenoptera possessed the highest richness 6 on 22 nd May. Diptera possessed the highest abundance 39. Morphological characteristics and behaviors of flower-visiting insects were described,and the behavior of same family species was similar.
