The relationship between number of holes in a grain probe trap body and capture of stored-grain pests was determined in laboratory tests using adults of the rice weevil, Sitophilus oryzae (L.), the sawtoothed grain beetle, Oryzaephilus surinamensis (L.), and the red flour beetle, Tribolium castaneum (Herbst). Polyvinylchloride (PVC) probe bodies were attached to electronic sensor heads, and ins...

J. Econ. Entomol. ii: 1144-1148 (1984) ABSTRACT Seed oils of many sapindaceous plants contain substantial amounts of cyanolipids. Several of these oils stimulated aggregation of the sawtoothed grain beetle, Oryzaephilus surinamensis (L.), and the confused flour beetle, Tribolium confusum (Jacquelin duVal). In a pitfall bioassay, they attracted the sawtoothed grain beetle and the rice weevil, Si...

abstract due to economical importance of stored product pests and resistance to conventional insecticides, it is necessary to use novel and suitable compounds in control programs. therefore, we evaluated the toxicity of spinosad to three important storage insect, red flour beetle, tribolium castaneum (herbst), rice weevil, sitophilus oryzae (l.), sawtoothed grain beetle oryzaephilus surinamensi...

The sawtoothed grain beetle, Oryzaephilus surinamensis (L.), is an important pest of packagedconsumer foods, yet little is knownof its behavioral response to foododors.Adults and larvae are not believed to chew holes through packaging materials, but they may invade packaged food by entering through openings caused by improper sealing or handling, throughholes intentionally placed in packages by...

The sawtoothed grain beetle, Oryzaephilus surinamensis (L.), is an extremely destructive pest of packaged consumer food products. The beetle is not believed to chew directly through packaging materials, but to use openings or flaws in damaged or improperly sealed packages to gain entry. We investigated the behavioral mechanisms by which the sawtoothed grain beetle infests packages with flaws. S...

The relationship of size of test arena, number of holes in a grain probe trap body and capture of the sawtoothed grain beetle, Oryzaephilus surinamensis (L.), was determined in simulated field tests conducted in an outdoor screen enclosure exposed to natural temperature fluctuations. Polyvinylchloride (PVC) probe bodies were attached to electronic sensor heads, and insect captures were recorded...

Spinosad is a commercial reduced-risk pesticide that is naturally derived. Spinosad's performance was evaluated on four classes of wheat (hard red winter, hard red spring, soft red winter, and durum wheats) against adults of the lesser grain borer, Rhyzopertha dominica (F.); rice weevil, Sitophilus oryzae (L.); sawtoothed grain beetle, Oryzaephilus surinamensis (L.); red flour beetle, Tribolium...

Two crystalline protoxins from Bacillus thuringiensis (Bt), Cry1Fa1 and Cry34Ab1/Cry35Ab1 (Cry1F, Cry34/ 35Ab1), were evaluated for efficacy against lepidopteran and coleopteran storage pests. Cry1F was tested against the lepidopterans Sitotroga cerealella (Angoumois grain moth) and colonies of Plodia interpunctella (Indian mealmoth) that are susceptible or resistant to Bt Cry1Ab and Cry1Ac tox...

Abstract The flavobacterium Shikimatogenerans and the alpha-proteobacterium Wolbachia both influence ecology evolution of sawtoothed grain beetle Oryzaephilus surinamensis . Genome analyses, phylogenetic inference manipulation three-partite association revealed two very different ways supporting beetle’s establishment adaptation as a global storage pest: synthesis aromatic amino acid precursors...

We tested the hypothesis that the entomopathogenic fungus Beauveria bassiana would be more efficacious on oat cultivars that prolonged the immature developmental period of sawtoothed grain beetle, Oryzaephilus surinamensis (L.), a storage pest. However, percentage of reduction in progeny production was similar on whole 'Don' and 'Paul' oats treated with fungus, even though immature developmenta...
