Abstract

Methanol and ethanol extracts of 14 plants from the Sonora, Mexico, area were evaluated for control of the larger grain borer, Prostephanus truncatus (Horn). Methanolic extracts resulted in significantly greater mortality. Extracts of bursage, Ambrosia ambrosioides (Cav.), gave 100% mortality; no larger grain borer adults emerged, and weight loss and damaged grains were low (0.1 and 0.3%, respectively). Extracts of climbing milkweed, Sarcostemma cynanchoides Decne, and Salpianthus macrodonthus also exhibited activity, causing more than 75% mortality and adult emergence lower than 30%.
