(Acarus siro)


 
Grain mites are very small, with size up to 0,5mm. They are whitish in colour with pink legs (they have 4 pairs of legs). They are resistant to low temperatures, but not to low humidity. With relative humidity less than 65% it is not possible for them to grow.
Female lays 500-800 eggs, with a rate of 20-30 per day. Life cycle is completed in about 2 weeks and the young larvae have 3 pairs of legs, like insects.
They infest cereals, fodder and nuts, deteriorating their quality.
Eggs are resistant to normal rates of fumigants and an increase of the dose, by 50%, is needed. The only effective method against cereal mites is to store the products in spaces with low humidity and dry atmosphere.
