Inhibition of a nutritional endosymbiont by glyphosate abolishes mutualistic benefit on cuticle synthesis in Oryzaephilus surinamensis [PDF]
Communications Biology, 2021 Kiefer et al. sequence the metagenome of the sawtoothed grain beetle and demonstrate how its symbiont mechanistically helps the host by providing tyrosine. Providing this amino acid in the pupal stage and early adulthood supports cuticle biosynthesis and

Cool Down–Warm Up: Differential Responses of Stored Product Insects after Gradual Temperature Changes [PDF]
Insects, 2020 Insect survival after exposure to 0 °C for 7 days was examined in laboratory bioassays for control of adults of six major stored-product beetle species, Oryzaephilus surinamensis (L.), the sawtoothed grain beetle, Cryptolestes ferrugineus, (Stephens)

Effect of Nitrogen on Phosphine-Susceptible and -Resistant Populations of Stored Product Insects [PDF]
Insects, 2020 In this study, we evaluated nitrogen treatment on phosphine-resistant field and -susceptible laboratory populations of different stored product beetles. Nine trials were conducted in commercial nitrogen chambers with the O2 level set at 1.0%.

Wolbachia causes cytoplasmic incompatibility but not male-killing in a grain pest beetle [PDF]
Molecular Ecology, Volume 31, Issue 24, Page 6570-6587, December 2022., 2022 Abstract The endosymbiotic Wolbachia is one of the most common intracellular bacteria known in arthropods and nematodes. Its ability for reproductive manipulation can cause unequal inheritance to male and female offspring, allowing the manipulator to spread, but potentially also impact the evolutionary dynamics of infected hosts.

First record of an indoor pest sawtoothed grain beetle <i>Oryzaephilus surinamensis</i> (Coleoptera: Silvanidae) from wild outdoor wood ant nest [PDF]
Entomologica Fennica, 2012 Alive individual adult sawtoothed grain beetle Oryzaephilus surinamensis (Linnaeus, 1758) was discovered inside a nest mound of the red wood ant Formica rufa Linnaeus, 1758 during a survey of myrmecophilous invertebrates. The sawtoothed grain beetle is a widespread indoor pest that has not previously been found in an ant nest.

Control of Sawtoothed Grain Beetles (Coleoptera: Silvanidae) in Stored Oats by Using an Entomopathogenic Fungus in Conjunction with Seed Resistance [PDF]
Journal of Economic Entomology, 2004 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 ...

Using a Lethality Index to Assess Susceptibility of Tribolium confusum and Oryzaephilus surinamensis to Insecticides. [PDF]
PLoS ONE, 2015 We evaluated knockdown caused by four insecticides: alpha-cypermethrin, chlorfenapyr, pirimiphos-methyl and fipronil against adults of Tribolium confusum Jacquelin Duval, the confused flour beetle and Oryzaephilus surinamensis (L.), the sawtoothed grain ...
