Changes in nutritional composition of soybean seed caused by feeding of pentatomid (Hemiptera: Pentatomidae) and alydid bugs (Hemiptera: Alydidae).

摘要: Changes in protein, lipid, and carbohydrate content, the weight loss of soybean seeds caused by feeding 6- to 7-d-old unmated male adults pentatomids Peizodorous hybneri (Gmelin) Halymorpha halys (Stal), an alydid, Riptortus pedestris (F.), were examined laboratory. Our goals determine which species had greatest capacity damage seed measure effect that on nutritional composition seed. Individuals three provided with a preweighed dry allowed feed for 0, 4, 8, 12, 16, 20, 24 d, after remaining was analyzed any change weight, concentration. Lipids, carbohydrates, weights reduced bug feeding, reduction directly proportional duration. H. found be most voracious feeder, reducing 42% d feeding. There significant interaction between duration changes components. Seeds fed highest incremental increase protein content (13%) followed those R. P. hybneri. However, carbohydrates lipid tested insect decrease significantly. Soybean pods at mature stages remain field long period, findings our study suggest longer exposure these pest may lead low-quality lower yields, even affect germination potential seeds.
