Abstract: We examined the diet of Chaunus arenarum during the entire soybean growth season at a locality in Córdoba province, Argentina. A total of 62 toads (14 in December, 10 in January, 14 in February, 14 in March, and 10 in April) were analyzed to assess gastrointestinal contents. A total of 1963 prey items were found, 1439 of which were considered harmful to soybean plants. In December the most frequently consumed prey item was Acromyrmex sp. (Hymenoptera, Formicidae), whereas in January, February, March and April the most abundant prey item was Armadillium vulgare (Crustacea, Isopoda). Significant correlations were detected between the percentage of harmful arthropods consumed and the height of the soybean plants for each month throughout the period. We suggest that C. arenarum should be considered a potential bio-control agent of soybean pests. be considered a potential bio-control agent of soybean pests. be considered a potential bio-control agent of soybean pests. Significant correlations were detected between the percentage of harmful arthropods consumed and the height of the soybean plants for each month throughout the period.
