Consumption by coleopteran insects on a wild soybean, Glycine soja Sieb. et Zucc.

Abstract

Wild soybean consumption by nine species of coleopteran adults and two species of Trachyinae larvae was investigated for the environmental assessment of Bt soybean. The leaf area eaten by the coleopteran adults per day was 1158, 915, 599, 30, 22, and 6 mm² for Mimela splendens, Anomala rufocuprea, Epicauta gorhami, Medythia nigrobilineata, Trachys reitteri, and Pagria ussuriensis, respectively. The total area eaten by the Trachyinae larvae was 200 and 599 mm² for T. reitteri and T. auricollis, respectively.
