摘要:

【目的】分析新疆塔里木盆地东南缘多枝柽柳的主要传粉昆虫及其传粉生物学特征,为该类植物的保护和利用提供参考。【方法】在研究区域的多枝柽柳开花后第1~3 d,每天09:00~19:00连续观察其上访花昆虫,研究访花昆虫类群,甄别并确定传粉昆虫种类,分析其传粉生物学特征;通过传粉昆虫单次访花后柱头花粉沉降数量及移出花粉数量的比值计量传粉昆虫的传粉效率。【结果】研究区域多枝柽柳的主要传粉昆虫包括粗腿毛带蜂Pseudapis femoralis、大分舌蜂Colletes gigas、艳叶舌蜂Hylaeus variegatus、艳小彩带蜂Ceylalictus variegatus、淡翅红腹蜂Sphecodes grahami和丝光绿蝇Lucilia sericata,其中粗腿毛带蜂(0.62)和大分舌蜂(0.60)的传粉效率高于其它传粉昆虫(P<0.05);6种传粉昆虫的访花活动在12:00~13:00时达到高峰,该高峰与多枝柽柳的花粉活力高峰重叠,随时间推移,观察到的访花昆虫数量逐渐减少。【结论】塔里木盆地荒漠、半荒漠生态区多枝柽柳的主要传粉昆虫包括粗腿毛带蜂、大分舌蜂、艳叶舌蜂、艳小彩带蜂、淡翅红腹蜂和丝光绿蝇;粗腿毛带蜂与大分舌蜂为高效的传粉者;传粉昆虫的访花活动高峰与柽柳的花粉活力高峰重合,两者间存在互利共生关系。

Abstract:

【Objective】 In natural state, it depends on insect pollinators for reproduction. Thus it is necessary to clarify the insect pollinators and reveal their biological characteristics of pollination. 【Methods】 We observed insect pollinators at 09:00-19:00 on the first three days after T. ramosissima blooming, attempting to reveal biological characteristics of pollinators. We also analyzed and compared insect pollinators' capability to remove pollens from anther and deposit them on stigma, thus evaluating their pollination efficiency. 【Results】 Among the insect visitors of T. ramosissima observed, the observed potential pollinators were Pseudapis femoralis, Colletes gigas, Hylaeus variegatus, Ceylalictus variegatus, Sphecodes grahami and Lucilia sericata; among them, the pollination efficiencies of Pseudapis femoralis (0.62) and Colletes gigas (0.60) were higher than Hylaeus variegatus(0.44), Sphecodes grahami(0.42), Ceylalictus variegatus(0.42) and Lucilia sericata(0.40) (P < 0.05). The insect pollinators of T. ramosissima began to visit flowers close to 09:00 after sunrise, and the peak of flower-visiting activities generally appeared at 12:00-13:00. This peak coincided with the peak of pollen viability of T. ramosissima. The number of visiting visiting gradually decreased over time. 【Conclusion】 In this study, we have noticed that the dominant insect pollinators of T. ramosissima are Pseudapis femoralis, Colletes gigas, Hylaeus variegatus, Ceylalictus variegatus, Sphecodes grahami and Lucilia sericata. Pseudapis femoralis and Colletes gigas are high-efficient pollinators. The peak of flower-visiting activities generally appears at 12:00-13:00, which coincided with the peak of pollen viability of T. ramosissima, reflecting the mutually beneficial symbiotic relationship between them.

Key words: desert and semi-desert ecological areas; insect pollinators; pollination efficiency; flower-visiting behavior; flower-visiting frequency; single flower stay time
