Many natural and synthetic essential oils have been used to control of this beetle. Saw-Toothed Grain Beetle (Oryzaephilus surinamensis) Adults, 2.5-3.5mm long; colour: dark brown; distance from eye to prothorax more than half vertical diameter of eye; 6 teeth along each side of prothorax (hence the name ‘Saw-toothed’). Suborder: Superfamily: Family: Subfamily: Species: POLYPHAGA Emery, 1886. Results showed the first step in the toxicity of free and microencapsulated formulations of BHA and BHT against O. surinamensis and T. … [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. Journal of Plant Protection Research 52: 397-400. (Oryzaephilus surinamensis and Sitophilus oryzae are more cold hardy and may take longer to kill than other species. I R. Cel. [6] In grain, insect damage decreases value and can make it unfit for use; sufficient numbers of insect fragments or live insects can result in rejection by the purchaser. [6], In the home, infestations can be avoided by storing dried food products in sealed containers. [2] 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. A Study on the Efficiency of Beauveria Bassiana Isolate Inoculation Release for Oryzaephilus surinamensis Control in Date Store Condition: Masoud Latifian and Bahar Rad: Abstract: In this research, Beauveria bassiana Bals mass release efficiency for microbial control of Saw-toothed beetle, Oryzaephilus surinamensis L. was studied in Date palm stored condition. Results: Essential oils of O. basilicum and E. globulus were tested for their volatile toxicity in the laboratory against sawtoothed beetle, O. surinamensis. The beetle larvae are also very susceptible to B. bassiana, a registered mycoinsecticide with excellent prospects for use against pests of grain in storage and processing. 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. Oryzaephilus spp. The standard technique recommended by F.A.O. Control survival for adults, larvae, and eggs was 100, 97, and 96%, respectively. Vuill., a registered mycoinsecticide. Biological control has not been practised against Oryzaephilus spp. Epsky, N.D. and Shuman, D. 2001. In Oklahoma, cooling by aeration reduced the percentage of grain bins that needed to be fumigated from 30–94% to 20–28%. Chemical control: The pest is developing resistance to many pesticides. tles, Oryzaephilus surinamensis (L.). These harmful pests include Oryzaephilus surinamensis Linnaeus which is the subject of this review. Female and male are nearly The species's binomial name, meaning "rice-lover from Surinam," was coined by Carl Linnaeus, who received specimens of the beetle from Surinam. In this study, ozone was applied in the gaseous form to control two species of pests in stored dried figs. Besides, sub-lethal levels of these compounds results in a loss of insects’ weight and change in protein content. Abstract. Many natural and synthetic essential oils have been used to control of this beetle. A life cycle requires 20–80 days at 18–37°C, and several generations may overlap because adults can live for 6-10 months. Monitoring: Usually by visual inspections, or by checking the temperature of the grain, which becomes warm. An electronic grain probe Insect counter system for monitoring this pest has been developed. The use of inert dust and carbonic organic acid alone or combined may be an alternative method to control stored grain pests. [6] The total life cycle is 27 – 51 days at 85–95 °F (29–35 °C). Botanical insecticides have long been used as alternatives to [2] It is a common, worldwide pest of grain and grain products as well as chocolate, drugs, and tobacco. CSIRO ScienceImage 2599 Sawtoothed Grain Beetle Oryzaephilus surinamensis .jpg 1,772 × 1,143; 2.17 MB. The body is very flat and is well adapted for crawling into cracks and crevices. [2], O. surinamensis is one of the most commonly encountered insects in grain, pet foods, and seeds. In commercial grain storage operations bins should be cleaned after emptying in order to prevent any insects from infesting new grain. Using only strong packing material without any holes. They are unable to feed on undamaged grains. Freezing and heating, an effective method for the control for several stored product pests, also affects the sawtoothed grain beetle. Fumigant toxicity of essential oils against four major stored–product insects. [2][6] Emergence as adults occurs after about one week[6], Adults can live on average six to ten months, though they can live as long as three years. Beckel, H., Lorini, I. and Lazzari, S.M.N. [6] The ideal temperature range for larvae development within eggs is about 27-29°C (80-85°F[6]), under such conditions they hatch in three to five days. There are three genera of Oryzaephilus and all these genera possess a series of teeth like appearance behind the eyes projection [10]. The preferred food of the sawtoothed grain beetle (Oryzaephilus surinamensis) are stored oat seeds. De wetenschappelijke naam van de soort werd voor het eerst geldig gepubliceerd in 1758 door Linnaeus als Dermestes surinamensis . BIOLOGICAL CONTROL AND PLANT PROTECTION . [2] The gasses used in fumigation (most often phosphine[7]) are highly toxic to both insects and mammals (including humans)[7] but when applied properly, no fumigant will remain in product after treatment is complete. widely used to control stored grain pests, however, its intensive use has lead to the development of insect resistance in many species and in many cases this represents a significant threat to the continuity of its effective use. The chemical control is the most popular and effective method.
