Nysius is one of the most common and widely distributed species in the world. It is one of the emerging pests of perilla crop in the field in Korea. In this study, we investigated the oviposition preference and development of Nysius plebeius and N. hidakai. on five crops seed (Perilla, Sesame, Proso-millet, Sorghum, and Fox-tail millet) using both multiple choice and no-choice tests. Both results found perilla seeds to be the most suitable seeds for oviposition and development. Total developmental period was shortest on perilla seed, and the longest was on rest of crops seeds. The highest of adult emergence, longevity, and adult weight were occurred on the perilla seed. This results suggest that the higher preference and performance of Nysius spp on the perilla seed. The information may facilitate the exploration of resistant genetic materials chemical associated with seeds for successful breeding program in Korea.
