Ovipositional Deterrents for Hylemya antiqua 1 in Hydrated Seeds of Phaseolus vulgaris 2

Abstract
Extracts from hydrated bean seeds ( Phaseolus vulgaris L.) deterred the ovipositional response of Hylemya antiqua Meig. to volatile attractants released by cut pieces of mature onion bulbs. Experiments using choice bioassays with gravid female adult flies indicated that the active principle(s) is a non-volatile, non-polar constituent of hydrated bean seeds that functions via a contact stimulus.
