Weevil will breed on maize in the field, but the Rice weevil only breeds in stored grain. Both insects are less coldhardy than the Grain weevil and will not normally overwinter in unheated premises or grain stored at normal temperatures. IMPORTANCE AS A PEST: Grain weevils are important pests of farm-stored grain. A complex of weevils, the rice (Sitophilus oryza), granary (Sitophilus granarius), and maize (Sitophilus zeamais) weevils, are among the most destructive pests of grains, seeds, and grain products stored in elevators and bins. They probably are not native to North America, but entered in seeds carried by settlers through ports. Celebrate with some highly-requested Spring and Easter nest items! Infestations from the angoumois grain moth are usually limited to the top few inches in the bin of stored grain, while the other insects can infect grain in pockets anywhere in the bin. Weevils and lesser grain borer insects have been identified as the most common internal infesters of wheat (Storey et al., 1982). Mar 07, 2011 A female weevil lays an egg inside a grain kernel. (She can do this up to 254 times!) The egg hatches and for one to five months depending on the season, the larva lives inside and feeds on the kernel as it grows. Upon reaching adulthood, the weevil emerges from the kernel to mate –.
