Abstract

Oviposition preferences of plant-feeding predators remain a complex topic, as such omnivores choose oviposition sites by assessing both plant characteristics and the quality and quantity of nearby animal food sources. Orius predators are omnivores that oviposit endophytically, thus plant characteristics play an important role in their oviposition choices. In this study, we assessed the oviposition and foraging preferences of O. laevigatus and O. majusculus on vegetative and flowering chrysanthemum plants, and assessed the survival of their offspring on differently aged tissues. Our results show a preference of O. laevigatus for young and tender chrysanthemum tissues, where the survival of the nymphs was longer on a plant diet. In contrast, O. majusculus selected older plant parts when laying its eggs, and nymphs did not survive long on any of the plant tissues offered. The foraging activity of Orius females for animal prey (Ephestia kuehniella eggs) did not reveal any specific pattern for either of the two predators. Furthermore, we tested the plasticity of the within-plant oviposition preferences of O. laevigatus, by offering sentinel prey (E. kuehniella eggs) on distinct plant parts. We found that more eggs were laid in older plant tissue when animal prey was offered lower on the plant. Overall, our findings show that oviposition choices of Orius predators are based on a dynamic interplay between plant characteristics, presence of animal and/or floral food sources among other factors, and that differences may well occur between closely related species based on the importance of plant resources in their diet.

Orius捕食者在植物内的产卵偏好和幼虫存活率的差异以及猎物空间可用性的重要性。
以植物为食的食肉动物的产卵偏好仍然是一个复杂的课题,因为这类杂食动物会通过评估植物特征和附近动物食物来源的质量和数量来选择产卵地点。金龟子食肉动物是内生性产卵的杂食动物,因此植物特征在其产卵选择中起着重要作用。在这项研究中,我们评估了 O. laevigatus 和 O. majusculus 在无性和有花菊科植物上的产卵和觅食偏好,并评估了它们的后代在不同老化组织上的存活率。我们的结果表明,O. laevigatus偏爱幼嫩的菊花组织,若虫在植物食物上的存活时间更长。相比之下,O. majusculus产卵时会选择较老的植物部分,若虫在提供的任何植物组织上存活时间都不长。Orius雌虫对动物猎物(Ephestia kuehniella卵)的觅食活动并没有显示出两种天敌的任何特定模式。此外,我们通过在不同的植物部位提供哨兵猎物(E. kuehniella卵),测试了O. laevigatus在植物内部产卵偏好的可塑性。我们发现,当动物猎物被提供给植物的较低部位时,更多的卵产在较老的植物组织中。总之,我们的研究结果表明,Orius捕食者的产卵选择是基于植物特征、动物和/或花卉食物来源等因素之间的动态相互作用,而且近缘物种之间很可能会因为植物资源在其食物中的重要性而出现差异。

期刊介绍: Insect Science is an English-language journal, which publishes original research articles dealing with all fields of research in into insects and other terrestrial arthropods. Papers in any of the following fields will be considered: ecology, behavior, biogeography, physiology, biochemistry, sociobiology, phylogeny, pest management, and exotic incursions. The emphasis of the journal is on the adaptation and evolutionary biology of insects from the molecular to the ecosystem level. Reviews, mini reviews and letters to the editor, book reviews, and information about academic activities of the society are also published.
