Adults are 2.5 mm (1/10 inch) long. Sieving in order to remove pest-containing damaged grains may limit infestations. SILVANIDAE Kirby, 1837. [2] O. surinamensis is less common in colder climates such as Canada and the Northern United States[2], A female can produce 43-285 eggs in their six to ten month average lifespan which are deposited on a food mass. Adult sawtoothed grain beetles are slender insects about 1/8 inches long. Botanical insecticides have long been used as alternatives to This work addresses the compatibility of the two biological control agents. However, laboratory mass rearing of this insect for bioassays is not a simple task, mainly because of its feeding behavior, small size, and high mobility. Chemical Control. In Oklahoma, cooling by aeration reduced the percentage of grain bins that needed to be fumigated from 30–94% to 20–28%. There are three genera of Oryzaephilus and all these genera possess a series of teeth like appearance behind the eyes projection [10]. [2] Because of the high toxicity of fumigants, their use is restricted to qualified applicators[2][6] and areas which can be tightly sealed. In commercial grain storage operations bins should be cleaned after emptying in order to prevent any insects from infesting new grain. (Oryzaephilus surinamensis and Sitophilus oryzae are more cold hardy and may take longer to kill than other species. [2] In food processing operations and warehouses other means of control may be necessary and fumigation is commonly used,[2] in large-scale grain storage operations a pesticide application may be needed for storage over six months. The chemical control is the most popular and effective method. This insect prefers milled cereal products. SILVANINAE Kirby, 1837. ability to control O. surinamensis in storage facilities. The standard technique recommended by F.A.O. Oryzaephilus Ganglbauer, 1899. Many natural and synthetic essential oils have been used to control of this beetle.

Laboratory studies have shown that lowering the RH increases the effectiveness of MAs. Current control methods are based on the use of insecticides, ... Oryzaephilus surinamensis (L.) in Australia is another example. The study showed that O. s urinamensis is abundant in acorns of Quercus calliprinos (Palestine oak). This insect was described as resistant to commonly used pesticides, such as fenitrothion, pirimiphos-methyl and chlorpyrifos methyl (Beckett et al., Reference Beckett, Evans and Morton 1996). The species's binomial name, meaning "rice-lover from Surinam," was coined by Carl Linnaeus, who received specimens of the beetle from Surinam. Shaaya, E. Ravid, U., Paster, N., Juven, B., Zisman, U. and Pisssarev, V. 1991. The preferred food of the sawtoothed grain beetle (Oryzaephilus surinamensis) are stored oat seeds. Chemical Control. conventional insecticides, it is necessary to use novel and suitable compounds in control programs. Besides, sub-lethal levels of these compounds results in a loss of insects’ weight and change in protein content. Oryzaephilus surinamensis, was the store insects that attack dry dates in the store.
