Larvae hatch and feed internally within the kernel.

Females release a sex pheromone which attracts males. Maize weevil infestations produce heat and moisture. https://doi.org/10.1016/j.anbehav.2009.10.022. The end of the body of the maize weevil is more rounded than that of the LGB, and its mouthparts are 'beak-like' and antennae elbowed. BioNET-EAFRINET Regional Coordinator: email@example.com, Sitophilus zeamais Motschulsky, 1855 - Maize Weevil, Coombs CW, Billings CJ, Porter JE, (1977). The larva remains inside the kernel until adult emergence. The impact of grain quantity on the biology of Sitophilus zeamais Motschulsky (Coleoptera: Curculionidae): oviposition, distribution of eggs, adult emergence, body weight and sex ratio. 1971. Meikle, W.G., Holst, N., Markham, R.H. 1999. The pest causes hollowing of whole previously undamaged grains. The maize weevil is found in all warm and tropical parts of the world. It has, however, been present for several years in Montreal, where grain from the U.S. is stored..
