摘要: 2010―2016年通过人工栽培小区试验,系统调查了33科152种植物上小花蝽复合种群发生动态。多年调查结果表明:除黄柴胡外,其余151种植物上均有小花蝽发生,但小花蝽的种群密度在不同调查年度的植物种类上差异较大。小花蝽种群发生密度最高的植物是蓝蓟,其次是芥菜、硫华菊、荞麦、紫花苜蓿、红麻、陆地棉等有大量蚜虫及开花周期较长的植物。本研究明确了农田生境中小花蝽发生密度较高的候选功能植物,为下一步利用植物多样性促进农田小花蝽种群的保育及控害功能提供科学依据。

Abstract: We monitored the occurrence of Orius spp. on 152 plant species belong to 33 families in field plots from 2010 to 2016. The Orius spp. was recorded on 151 plant species except for Bupleurum falcatum. The density of Orius spp. varied greatly between years and plant species. Echium vulgare supported the highest density of Orius spp., other plants such as mustard Brassica juncea, sulfur cosmos Cosmos sulphureus, buckwheat Fagopyrum esculentum, alfalfa Medicago sativa, kenaf Hibiscus cannabinus, and cotton Gossypium hirsutum also supported higher Orius spp. populations. These plants harbored high aphid densities and maintained relatively longer flowering periods, which might have provided sufficient preys and nutrition to Orius spp. The study provides an insight into using functional plants to support predatory Orius spp. and enhance their potential biocontrol services on insect pests in agricultural ecosystem.

Key words: Orius spp., population density, function plant, natural enemy conservation
