Abstract

The bean bug, Riptortus pedestris (Fabricius), is one of the major pests of soybean; this pest mainly feeds on soybean pods. Its population is highest when the soybean plants bear mature seeds. We aimed to determine the effect of bean bug infestation on soybean according to changes in nutrient levels and seed germination potential. Newly emerged adult males of R. pedestris (n= 5 per plant) were released into a meshed cage containing soybean plants at the R5 stage. Another meshed cage with soybean plants was treated as control. Healthy seeds harvested from control plants were selected and accounted as undamaged seeds and seeds from bug-released cages were visually categorized into 7 different classes according to the intensity of damage incurred due to bean bug infestation. The seeds were then compared in terms of changes in weight, protein, lipid, and carbohydrate content, and germination potential. Elevated protein levels were observed in seeds that showed a higher intensity of damage. On the other hand, the lipid and carbohydrate contents and germination potential were reduced in seeds showing a higher degree of damage. Germination potential in terms of lipid and carbohydrate loss caused by bug infestation is also discussed.
