Insects visit flowers not only to forage for nectar or pollen but also to search for hosts or prey, and to look for suitable habitats for breeding sites. In oil palm flowers, it has been documented that not all flower-visiting insects are pollinators, but some insects are recognized as predators, parasitoids or saprophages, which may affect the abundance and persistence of the weevil pollinating oil palm, . We studied the community of oil palm flower-visiting insects and investigated the covariation between the abundance and that of other dominant species. Ecological research was conducted in oil palm plantations with different tree ages in Central Borneo. Our results found that tree age and flower type of oil palm did not influence the abundance and species richness of flower-visiting insects, but significantly affected their species composition. There was a significant positive relationship between the abundance of and the fly sp, indicating that these species covariate in oil palm flowers. These findings suggest that understanding the covariation between and sp may help develop the conservation strategies for to support the sustainable production of oil palm.
昆虫拜访花朵不仅是为了觅食花蜜或花粉，也是为了寻找宿主或猎物，以及寻找适合繁殖的栖息地。在油棕榈花中，已有文献记载并非所有拜访花朵的昆虫都是传粉者，有些昆虫被认为是捕食者、寄生蜂或腐食者，这可能会影响为油棕榈授粉的象鼻虫的数量和持续性。我们研究了拜访油棕榈花的昆虫群落，并调查了其数量与其他优势物种数量之间的协变关系。在婆罗洲中部不同树龄的油棕榈种植园中进行了生态研究。我们的结果发现，油棕榈的树龄和花的类型并未影响拜访花朵昆虫的数量和物种丰富度，但显著影响了它们的物种组成。象鼻虫数量与蝇类物种数量之间存在显著的正相关关系，表明这些物种在油棕榈花中协变。这些发现表明，了解象鼻虫与蝇类物种之间的协变关系可能有助于制定保护象鼻虫的策略，以支持油棕榈的可持续生产。
