摘要
对入侵中国华南地区的薇甘菊的传粉昆虫及其访花行为的研究结果表明,薇甘菊的访花昆虫有30种,隶属于6目19科,以膜翅目、双翅目和半翅目为主.稳定的和访花频率较高的传粉者主要为蜜蜂、丽蝇和食蚜蝇,其中以丽蝇的访花频率为最高.蜜蜂的每日访花频率的高峰出现在9:00—10:00和15:00—16:00,而丽蝇和食蚜蝇则为11:00—12:00和14:00—15:00.环境因子和同花期植物(如薇甘菊的伴生种火炭母)对访花频率有一定的影响.
The pollinating insects of the invasive weed Mikania micrantha H.B.K.and their foraging behavior were observed in an open population in South China.A total of 30 insect species belonging to 19 families in 6 orders were identified as floral visitors and most of them were from Hymenoptera,Diptera and Hemiptera.Moreover,Apis sp.,Calliphoridae and Syrphidae were common and frequent floral visitors with Calliphoridae being the most frequent.The peaks of visiting frequency for Apis sp.were 9：00—10：00 and 15：00—16：00,while those for Calliphoridae and Syrphidae were both 11：00—12：00 and 14：00—15：00.Environmental factors and the plants（such as Polygunum chinense L.） having the same floral period had certain influence on the visiting frequency of M.micrantha.
