Natural enemies play an important role in managing insect pests. (Poppius) (Hemiptera: Anthocoridae), a predator of many soft-body insects, is an important biological control agent in Asia. Understanding this predator's egg-laying preferences and a habitat needs is important for its success in pest control. We investigated the plant acceptability and ovipositional preference of for coriander ( L., Apiales: Apiaceae), marigold ( L., Asterales: Asteraceae), sweet alyssum ( L., Brassicales: Brassicaceae), and alfalfa ( L., Fabales: Fabaceae), and focused on the effects of plant physical and anatomical characteristics on the ovipositional preference of . The results showed that can lay eggs on uninfested plants in the vegetative stage and their eggs hatched normally. females prefer plants with high stomatal density, a large stomatal area, and fewer trichomes as oviposition hosts, and the depth of egg placement was determined by leaf thickness. Our studies suggested that females can select oviposition hosts and specific oviposition sites by assessing the structural qualities of plant surface. Coriander and marigold are potentially suitable host plants for The results aid the selection of cover crops to enhance natural enemies in the fields.
天敌在害虫防治中发挥着重要作用。小花蝽(Poppius)(半翅目:花蝽科)是许多软体昆虫的捕食者,是亚洲一种重要的生物防治剂。了解这种捕食者的产卵偏好和栖息地需求对其在害虫防治中的成功至关重要。我们研究了小花蝽对香菜(Coriandrum sativum L.,伞形目:伞形科)、万寿菊(Tagetes erecta L.,菊目:菊科)、香雪球(Lobularia maritima L.,十字花目:十字花科)和苜蓿(Medicago sativa L.,豆目:豆科)的植物可接受性和产卵偏好,并重点关注植物物理和解剖特征对小花蝽产卵偏好的影响。结果表明,小花蝽可以在营养期未受侵染的植物上产卵,且其卵正常孵化。小花蝽雌虫更喜欢气孔密度高、气孔面积大且毛状体较少的植物作为产卵寄主,卵的放置深度由叶片厚度决定。我们的研究表明,小花蝽雌虫可以通过评估植物表面的结构质量来选择产卵寄主和特定的产卵部位。香菜和万寿菊可能是小花蝽合适的寄主植物。这些结果有助于选择覆盖作物以增强田间的天敌。
