Latin name: Oryzaephilus surinamensis

Description :

The beetle is reddish brown.
It is 2.5 to 3 mm long.
Its body is elongated and flattened.
On each side of the thorax, you can see 6 similar saw toothed growths.
It is from these traits that it takes its name.

The larva looks like a worm, and measures less than 3mm. It is greyish white and has
a brown head.


During its life, a female can lay 300 eggs. They are deposited randomly
in the mass of food or in clusters in a cracked grain.
The eggs of the beetle hatch in 3 to 5 days after spawning and larvae begin
to move freely, feeding on what they find in their path.
In less than 40 days, the larvae molt 2 to 4 times.
Depending on its environment.the entire cycle lasts from 3 to 10 weeks.
When the larvae are 3-4 mm long, they build a cocoon that they cover with
grain fragments using a sticky secretion. They will transform
inside it..
Adults will emerge a week later.
Temperature limits for complete development are between 17 and 37 ° C.


The sawtoothed grain beetle has spread worldwide. In Canada, it is
found mostly in milled grain products such as cereals, bread and macaroni,
and sometimes in grain silos.
It attacks foods such as nuts, sugar, spices, dried fruits and meats
and many other commodities.

supermarkets and residences).
