Many crop plants rely on insect pollination, particularly insect-pollinated crops which are functionally dioecious. These crops require insects to move pollen between separate plants which are functionally male or female. While honey bees are typically considered the most important crop pollinator species, many other insects are known to visit crops but the pollination contribution of the full diversity of these flower visitors is poorly understood. In this study, we examine the role of diverse insect pollinators for two kiwifruit cultivars as model systems for dioecious crops: var. 'Hayward' (a green-fleshed variety) and A. var. 'Zesy002' (a gold-fleshed variety). In our round-the-clock insect surveys, we identified that psychodid flies and mosquitoes were the second and third most frequent floral visitors after honey bees ( L), but further work is required to investigate their pollination efficiency. Measures of single-visit pollen deposition identified that several insects, including the bees spp. and spp. and the flies and , deposited a similar amount of pollen on flowers as honey bees (). Due to their long foraging period and high pollen deposition, we recommend the development of strategies to boost populations of spp., and other hover flies, and unmanaged bees for use as synergistic pollinators alongside honey bees.
许多作物依赖昆虫授粉,特别是功能上雌雄异株的虫媒授粉作物。这些作物需要昆虫在功能上为雄性或雌性的单独植株之间移动花粉。虽然蜜蜂通常被认为是最重要的作物传粉者物种,但已知许多其他昆虫也会访问作物,但对这些花卉访客的全部多样性的传粉贡献却知之甚少。在这项研究中,我们以雌雄异株作物的两种猕猴桃品种“Hayward”(绿肉品种)和 A. var. “Zesy002”(金肉品种)为模型系统,研究了多种昆虫传粉者的作用。在我们 24 小时的昆虫调查中,我们发现蕈蚊科蝇和蚊子是仅次于蜜蜂(L)的第二和第三大常见访花者,但还需要进一步研究它们的传粉效率。单次访问花粉沉积的测量结果表明,包括蜜蜂 spp. 和 spp. 以及蝇 和 在内的几种昆虫在花朵上沉积的花粉量与蜜蜂相似()。由于它们的觅食期长且花粉沉积量高,我们建议制定策略来增加 spp.、 和其他食蚜蝇以及未经管理的蜜蜂的数量,将它们作为与蜜蜂协同的传粉者。
