Laboratory kernel-kernel interaction experiments were carried out to assess the influence of mechanically damaged, insect-damaged, and intact maize kernels (conditioned or not) on the behavior of adult maize weevil, Sitophilus zeamais Motschulsky. S. zeamais adults were much more attracted to insect-damaged or conditioned insect-damaged kernels, than by the other two conditioned kernel categories considered. The intact kernels were more attractive than conditioned mechanically damaged kernels, but without significant difference. The "attractiveness" order of the kernel for S. zeamais adults was: insect damagedϾintactϾmechanically damaged. When fresh mechanically damaged and stored mechanically damaged kernels as well as fresh insect-damaged and stored insect-damaged kernels were compared, significant differences in the attraction of S. zeamais adults were noted.
