Abstract:Kernels of corn inbred lines A619 (susceptible) and B37 (resistant) were extracted sequentially with chloroform, hexane, and ethanol. The extracts and the residue were tested for chemosensory reactions of Sitophilus oryzae (L.). The ethanol extract of A6l9 incorporated into pellets composed of laundry starch stimulated oviposition and attracted weevils in an olfactometer for a l-h period, whereas the chlorofonn extract of both lines induced weevil aggregation in starch pellets for 1 week. The hexane extract and the residue of both lines did not cause a noticeable response by the weevils.
