Oryzaephilus surinamensis, the sawtoothed grain beetle, [1] is a beetle in the superfamily Cucujoidea. [2] It is a common, worldwide pest of grain and grain products as well as chocolate, drugs, and tobacco. [2] The species' binomial name, meaning "rice-lover from Suriname," was coined by Carl Linnaeus, who received specimens of the beetle from ...
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]
It can be distinguished from other grain beetles from its slight projections or knobs on each front corner of the pronotum, and its club-shaped antennae. However, other Ahasverus species look very similar and particular confusion can occur with Ahasverus rectus , which is also found in grain bins in North America.
The beetle life cycle lasts about three years or more, with the larval stage ranging anywhere from 20 to over 100 days, and the pupal stage around eight days. Beetles usually breed in damaged grain, grain dust, high-moisture wheat kernels, and flour.
Upon paralyzing a host (a beetle larva or pupa) the female typically lays 2 eggs (one female and one male) onto the host's body. When 2 larvae develop on the same host they develop on average in 2/3 the time required for a solitary larva to develop. The life cycle is completed in ~20 days at room temperature on Oryzaephilus surinamensis ...

The confused flour beetle (Tribolium confusum), a type of darkling beetle known as a flour beetle, is a globally found, common pest insect known for attacking and infesting stored flour and grain. They are one of the most common and most destructive insect pests for grain and other food products stored in silos, warehouses, grocery stores, and ...
Gnatocerus cornutus mainly feed on various types of grain, yeasts, and flours. [1] The broadhorned flour beetle undergoes 4 major life stages: egg, larvae, pupa, and adult. The total developmental time is about 47 days, about 1.5 times longer than the Tribolium castaneum, or red flour beetle. [2] In the larval stages of broad-horned flour ...
