Several pentatomids and an alydid are reported inflicting losses in several host plants ranging from leguminous crops to fruit orchards in Korea. Understanding their visual preference would help develop mass trapping or efficient monitoring device. Visual preference of the major pentatomids and an alydid bugs to different colors and light emitting diodes (LED) of different wavelengths were observed. Adults of pentatomid such as Halyomorpha halys Stål, Plautia Stali Scott, and Nezara sp., and an alydid Riptortus pedestris (F.) were exposed to seven different colors (black, yellow, green, blue, white, cream, orange) in a multiple choice tests. Also, adult and second instar nymphs of the bugs were released inside a hexagonal LED boxes consisting of LED lamps of six different wavelengths (375 to 630 nm). Most of the pentatomids showed highest preference to blue color followed by yellow and 530 nm LED. However, R. pedestris showed higher preference to the yellow color followed by blue and black. Second instar nymphs of all the tested species also showed higher preference to 530 nm. Their color and LED lamp preference would help in development of mass trapping device.
