摘要

柚木是一种昆虫传粉的物种,其种子生产依赖于传粉者。本研究的目的是确定柚木的潜在传粉媒介及其觅食行为,以获得替代食物来源,为管理建议提供依据。在3 ~ 5月花期,在花丛中设置Moczarsky-Winkler诱捕器、粘捕器、黄盘诱捕器和人工诱捕器(蚊帐)4种诱捕器。每周收集昆虫并进行计数和鉴定。观察花粉在它们身上的存在和位置。观察了采食行为的时间和持续时间、单次访花的持续时间、1小时内的访花次数以及接近柚木花和林下植被时的着陆位置。结果表明:Ceratina sp.、Braunsapis sp.(蚜科)、Nomia sp. (Halictidae)是东爪哇CSO中潜在的柚木传粉媒介。昆虫的觅食行为支持将花粉沉积到柱头上的能力。含羞草在林下的存在为传粉者提供了另一种食物来源。应减少对老枝或枯枝的密集除草和修剪,以增加传粉昆虫的数量和筑巢地点。

The behavior of insect pollinators in a teak (Tectona grandis L. f.) clonal seed orchard with weedy understory in East Java
Abstract Teak is an insect-pollinated species, and seed production depends on pollinators. The objectives of this study were to determine potential pollinators of teak and their foraging behavior in obtaining alternate food sources as the basis for management recommendations. Four traps, i.e. Moczarsky-Winkler selector traps, sticky traps, yellow-pan traps, and manual traps (insect net), were put up among blooming inflorescences during the flowering period of March to May. Insects were collected and counted weekly and identified. The presence and location of the pollen on their bodies were observed. The time and duration of foraging behavior, the duration of a single visit, the number of visits in an hour, and the landing position when approaching the teak flower as well as the understory were also observed. The result showed Ceratina sp., and Braunsapis sp. (Apidae), Nomia sp. (Halictidae) were potential teak pollinators in the CSO in East Java. The insect foraging behavior supports the ability to deposit pollen onto the stigma. The presence of Mimosa pudica in the understory plays as an alternate food source for pollinators. Intensive weeding and trimming of old or dead branches should be less practiced to enhance pollinators’ populations and nesting sites.
