説明

The analysis of soybean seed injuries caused by three species of stink bugs was carried out by releasing individuals among potted soybean plants. Damage caused by 1st and 2nd instar nymphs of Riptortus clavatus was not as severe as that caused by 3rd to 5th instar nymphs. Percentages of heavily damaged seeds were high in a plot where 4th instar nymphs and adults were released. The injuries caused by R. clavatus or Piezodorus hybneri were most severe at plant stages from middle podelongation to earlier seed-thickening. The total number of seeds injured by both males and females were almost the same for R. clavatus and Dolycoris baccarum, although the degree of injury were inflicted by the two species differed. Number of seeds injured by a single individual per day depended on the stages of R. clavatus and the stages of soybean plants. The number was largest when middle pod-elongation stages were attacked by female adults.
