The maize weevil, Sitophilus zeamais Motschulsky (Coleoptera: Curculionidae), is one of the most destructive pests of stored cereals. The life span of the granary beetle is 7-8 months on average. The origin of the maize weevil is not known but now it is found in all warm and tropical parts of the world. This activity was undertaken as part of the BioNET-EAFRINET UVIMA Project (Taxonomy for Development in East Africa). The large emergence holes with irregular edges are characteristic. It is a pest of stored maize, dried cassava, yam, common sorghum and wheat. The loose silk oval shape cocoon is 20-30 mm in length. The life-cycles of the Rice and Maize weevils follow a similar course to that of the Grain weevil. The antennae have eight segments and are often carried in an extended position when the insect is walking. 0000001116 00000 n In Tanzania, maize losses of up to 35 percentage may occur due to P. truncatus in 5-6 months if improperly stored (Mallya, 1992), and up to 60 percentage after nine months of storage (Keil, 1988); a situation that may result in a serious famine. These weevils are pests of grain throughout the world. Stored Products Management, 2nd Ed. Grains which float in water often indicate larval damage. Symptoms & Life Cycle.
