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
