Ovicidal, larvicidal and anti-ovipositional activities of Bifora radians and other plant extracts on the grape berry moth Paralobesia viteana (Clemens)
Journal of Pest Science 84 (4), 487-493
Abstract: Methanol extracts of Bifora radians, Arctium lappa, Humulus lupulus and Xanthium strumarium were tested against the North American grape berry moth, Paralobesia viteana in laboratory and greenhouse assays. Egg hatch was reduced by B. radians and X. strumarium extracts, whereas larval mortality was observed in response to B. radians, X. strumarium and A. lappa. Given the high mortality against egg and larval stages of this pest caused by extracts of B. radians, further studies were performed to determine the dose-response relationships between extracts of this plant and oviposition and egg hatch of P. viteana. There was a significant reduction in egglaying and egg hatch with increasing extract concentration, with 0.1% extracts providing 80% mortality and 1% extracts causing more than 90% control. This study demonstrates the potential of this plant extract for crop protection against a key pest of grapes and suggests that additional crop pests and field tests should be pursued to determine the efficacy of B. radians extracts as a biopesticide.
