Prostephanus truncatus is commonly referred to as larger grain borer (LGB) with reference to the related Rhyzopertha dominica, which is relatively smaller, and referred to as the lesser grain borer. P. truncatus is about 6 mm (0.24 in) long as compared to 3 mm (0.12 in) long in R. dominica .
The wheat weevil (Sitophilus granarius), also known as the grain weevil or granary weevil, is an insect that feeds on cereal grains, and is a common pest in many places. It can cause significant damage to harvested stored grains and may drastically decrease crop yields. The females lay many eggs and the larvae eat the inside of the grain kernels.
A storage pest is an insect or other animal that damages or destroys stored food or other stored valuable organic matter. [1] Insects are a large proportion of storage pests with each type of crop having specific insects that gravitate towards them such as the genus Tribolium that consists of insects such as Tribolium castaneum (red flour beetle) or Tribolium confusum (confused flour beetle ...
O. surinamensis is a slender, dark brown beetle 2.4–3 mm in size, with characteristic "teeth" running down the side of the prothorax. [4] It is nearly identical to Oryzaephilus mercator, or the Merchant Grain Beetle, [2] however, O. surinamensis has smaller eyes and a broader, more triangular head; [2] O. surinamensis unlike O. mercator are unable to fly.
Oryzaephilus mercator, the merchant grain beetle, is a small, flattened beetle about 2.5mm in length. [1] It is a common, worldwide pest of grain and grain products as well as fruit, chocolate, drugs, and tobacco. [1] The biology of O. mercator is nearly identical with Oryzaephilus surinamensis (the sawtooth grain beetle). [1]

An adult emerges from inside a grain of rice. Adult rice weevils are able to fly, [6] and can live for up to two years. Females lay 2–6 eggs per day and up to 300 over their lifetime. The female uses strong mandibles to chew a hole into a grain kernel after which she deposits a single egg within the hole, sealing it with secretions from her ...
