VIDEO LINK: https://youtu.be/IM_CbxmqNyk = How Did Sawtoothed Grain Beetles Orysaephilus surinamensis Come to and Infest Oat Flakes and Oat Porridge? Entomologist Dr Victor Fursov tells the story how dangerous beetles, sawtoothed grain beetles Orysaephilus surinamensis (Coleoptera, superfamily Cucujoidea, family Silvanidae) can infest flour, cereals and different food materials.
Oryzaephilus surinamensis, the sawtoothed grain beetle, is a beetle in the superfamily Cucujoidea. It is a common, worldwide pest of grain and grain products as well as chocolate, drugs, and tobacco.
A female ofbeetle can produce 43-285 eggs in their six to ten month average lifespan which are deposited on a food mass.
Larvae are yellow-white with brown heads and grow up to 3mm. They crawl freely around the food mass and feed on broken pieces of grain or grain kernels damaged by other insects, larger larvae may bore into kernels. Larvae account for the majority of damage done to grain.Larvae molt two to four times before pupation.
Larvae pupate by constructing cocoon-like coverings using broken pieces of grain. Emergence as adults occurs after about one week.
Adults can live on average six to ten months, though they can live as long as three years. The total life cycle is 27 – 51 days at 85–95 °F (29–35 °C). Adults seek out new sources of food for breeding.
O. surinamensis is one of the most commonly encountered insects in grain, pet foods, and seeds. Feeding results in shrinkage of the dry mass of the infested product and in increased water content due to the metabolic activity of the insects which can result in mold growth.
In the home, infestations can be avoided by storing dried food products in sealed containers. To control already present infestations, the infested material needs to be identified and disposed of, or frozen- as all life stages of the beetle can be killed by being frozen for six days.
.Fumigation is commonly used to control stored product pests in food and grain, this involves the treatment of product with gasses which are able to diffuse throughout the treated area.
