Rhyzopertha dominica (Fabricius, 1792) - (lesser grain borer)
has a worldwide distribution and is an important pest of stored whole cereal grains. Other stored products may be also attacked, like stored cassava products, nuts, legumes, dried fruits and even dried meat. Grain shipments may be infested and are often responsible for the introduction of the pest. In addition, the adult is able to fly short distances. The adult feeds on the grain, but lays its eggs outside the grain. The young larvae bore into the grain and live and pupate inside. Grains with cracks can facilitate entry of the larvae. The development from egg, through 4 larval stages, to mature adult lasts around 3-4 weeks under favorable conditions. Management involves monitoring stores with pheromone traps. Advanced infestations involves complete removal of the products and careful cleaning of the store. Fumigation is often applied to light infestations.
The adult is 2-3 mm long, dark brown to black. Seen from above, the head is partly or completely hidden by the pronotum which is pitted with a series of knobs along its front edge. The antenna have 10 segments including a 3-segmented club. The elytra have rows of pits, each with a curved seta.
