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.
Weevils also are known to infest oats, rice, corn, corn meal, sorghum, and cereal, so you might want to apply the same practice you do to your flour as those items as well.
Similarly to the lesser grain borer, maturation also happens inside the grain with the matured adult rice weevil eating through the husk of the grain to get out. The life cycle is similar to that of the lesser grain borer in summer months (approximately one month) and adult weevils live up to 8 months after the experience their life cycle. [3]
Control of weevils involves locating and removing all potentially infested food sources. Rice weevils in all stages of development can be killed by freezing infested food below −18 °C (0 °F) for a period of three days, or heating to 60 °C (140 °F) for a period of 15 minutes. [9]
Ragged holes in individual grains, similar to damage caused by the rice weevil and granary weevil, may indicate infestation. [6] In large stores of grain, an increase in temperature may be detected. The most obvious sign of infestation is the emergence of adults. One study recorded, 5 weeks after infestation, the emergence of 100 adults per kg ...
The sole species, Rhyzopertha dominica, is known commonly as the lesser grain borer, American wheat weevil, Australian wheat weevil, and stored grain borer. [3] It is a beetle commonly found within store bought products and pest of stored cereal grains located worldwide. [4] It is also a major pest of peanuts.
Sitophilus is a genus of weevils in the tribe Litosomini.Some species are familiar as pests of stored grain, nut, or seed. Notable pest species include the rice weevil (S. oryzae), wheat weevil (S. granarius), and maize weevil (S. zeamais).
Most stores have a plan of action for insect infestations. Bringing an infested product into a pantry or a home leads to a greater degree of infestation. In the home, putting cereal or grain-type items in protective containers will also help to prevent an infestation or the spread of insects from one product to another.
