摘要
对新疆阿魏访花昆虫种类、昆虫访花频次、昆虫访花时间及昆虫访花行为进行了初步研究。在盛花期观察中,(1)发现有5目、23科、45种昆虫进行了访花,其中传粉昆虫4科7种,均属蜜蜂总科;(2)各类昆虫访花频次在不同观察时间变化较大,传粉蜜蜂仅出现在其中一个观察日中;(3)不同种类昆虫在花上的停留时间差异很大,传粉昆虫停留时间很短,鞘翅目昆虫停留时间最长。进入始果期后,昆虫的访花行为是围绕花盘的蜜腺展开的。
We collected the insects on the flowers of Ferula sinkiangensis G. M. Shen (Umbelliferae) in Xi-jiang,west China. An observation was conducted about their visiting frequency,staying time,and behavior on the flowers. Forty-five species,23 families,5 orders,visited the flowers,among which pollinating insects were bees with seven species of four families (Apoidea,Hymenoptera). The pollinating bees occurred one out of seven days of observation and stayed a short time on the flowers. Coleopteran insects stayed longest on the flowers for feeding the nectary. The flower-visiting behavior was for the nectary during early fruit-ing period of the plant.
