Abstract

Honeydew is a nutrient rich excretion of aphids. This substance also emits kairomones, serving as a signal that attracts aphid predators and thereby influences the interaction among plants, aphids, and other predators. The overall aim of this study was to investigate the role of honeydew from two aphids species, Aphis fabae Scopoli, 1763 and Acyrthosiphon pisum (Harris 1776) in the predatory behavior of Adalia bipunctata (Linnaeus 1758) and Episyrphus balteatus (De Geer 1776). Specifically, we aimed to (1) evaluate the impact of honeydew on A. bipunctata and (2) E. balteatus and on intraguild interactions (IGI) among them. Our results showed that the presence of honeydew enhanced the mobility of predators by stimulating foraging behavior. In addition, the number of aphids consumed was significantly higher in the presence of honeydew. Interestingly, the predators were more attracted to A. fabae in the presence of A. pisum honeydew. These findings highlight the key role of honeydew in intraguild relationships, altering the prey’s perception from being less preferred to becoming more appealing to predators, akin to their favored prey. These results provide interesting perspectives to improve aphid biological control.

蚜虫蜜露在群落内部相互作用中的作用：增强 Adalia bipunctata 和 Episyrphus balteatus 之间捕食者的流动性、觅食和动态性

蜜露是蚜虫的一种营养丰富的排泄物。这种物质还能释放凯洛蒙，作为吸引蚜虫捕食者的信号，从而影响植物、蚜虫和其他捕食者之间的相互作用。本研究的总体目标是调查两种蚜虫（Aphis fabae Scopoli, 1763 和 Acyrthosiphon pisum (Harris 1776) ）的蜜露在 Adalia bipunctata (Linnaeus 1758) 和 Episyrphus balteatus (De Geer 1776) 捕食行为中的作用。具体来说，我们的目的是：（1）评估蜜露对 Adalia bipunctata 和 Episyrphus balteatus（De Geer 1776）的影响，以及对它们之间的种内相互作用（IGI）的影响。我们的研究结果表明，蜜露的存在会刺激捕食者的觅食行为，从而提高它们的活动能力。此外，有蜜露存在时，捕食的蚜虫数量明显增加。有趣的是，在有 A. pisum 蜜露存在的情况下，捕食者对 A. fabae 的吸引力更大。这些发现凸显了蜜露在动物群落内部关系中的关键作用，它改变了猎物的感知，使猎物从不感兴趣变成对捕食者更有吸引力，就像它们喜欢的猎物一样。这些结果为改善蚜虫生物控制提供了有趣的视角。

期刊介绍： Arthropod-Plant Interactions is dedicated to publishing high quality original papers and reviews with a broad fundamental or applied focus on ecological, biological, and evolutionary aspects of the interactions between insects and other arthropods with plants. Coverage extends to all aspects of such interactions including chemical, biochemical, genetic, and molecular analysis, as well reporting on multitrophic studies, ecophysiology, and mutualism. Arthropod-Plant Interactions encourages the submission of forum papers that challenge prevailing hypotheses. The journal encourages a diversity of opinion by presenting both invited and unsolicited review papers.
