AN EXPERIMENTAL TEST OF FRAGMENTATION AND LOSS OF HABITAT WITH ORYZAEPHILUS SURINAMENSIS
Ecology, 2003This research used a model experimental system to explore the joint effects of resource fragmentation and resource deterioration on population dynamics. The system provides a rapid test of conservation theory and can aid in planning for large and expensive studies.

Journal of Stored Products Research, 1981
Abstract The development of Oryzaephilus acuminatus Halstead was investigated over a range of temperatures from 17.5–40°C in combination with humidities from 15–90% r.h. on oatmeal. Development was also studied on groundnuts and copra meal at 30°C, 70% r.h. Eggs failed to hatch at 15°C but eclosion occurred at all other temperatures. The shortes mean

Humidity Response of the Larvae of Oryzaephilus surinamensis (Coleoptera: Cucujidae)
Annals of the Entomological Society of America, 1971The humidity response of the larvae of the saw-toothed grain beetle, Oryzaephilus surinamensis (L.), was investigated, using alternative chambers in which the larvae were presented with a choice between 2 relative humidities. The larvae did not respond when the alternatives were located in the lower portion of the RH range, but as the position of the ...

Light, Tactile, and Humidity Responses of Adult Oryzaephilus surinamensis1
Environmental Entomology, 1973Adult Oryzaephillls surinamensis (L.) showed a strong hygronegative response to a choice between relative humidity alternatives of 60 and 100% and a moderate hygropositive response to a choice between 10 and 50%, but they were indifferent, or nearly so, to alternatives of 0 and 40% RH .

Efficacy of Ozone Against the Life Stages of Oryzaephilus mercator (Coleoptera: Silvanidae)
Journal of Economic Entomology, 2017Ozone is a highly oxidizing gas with insecticidal activity and it is a potential alternative to conventional fumigants, such as phosphine and methyl bromide, for managing stored product insects. Susceptibility of the merchant grain beetle, Oryzaephilus mercator (Fauvel; Coleoptera: Silvanidae), an important pest of stored products, to ozone treatments ...

Nutritional relationships in larvae of Oryzaephilus surinamensis
Journal of Insect Physiology, 1967Abstract The saw-toothed grain beetle, Oryzaephilus surinamensis (L.), was reared to the adult stage on synthetic diets at 32±2°C and 75 per cent r.h. In the absence of RNA, dietary aspartic acid increased survival and rate of development of this insect.

Malathion for the control of Oryzaephilus surinamensis in stored oats
Journal of Stored Products Research, 1974Abstract Malathion was applied at an overall dosage of 8 or 12 ppm to layers of stored oats transferred with an auger to small bins of 12·3 metric tons capacity. The oats were heating (35–40°C) and were heavily infested (231 insects/kg) with Oryzaephilus surinamensis (L.). Malathion controlled the infestation at 12 ppm but not at 8 ppm. A bin of 10·8

The demography of Oryzaephilus surinamensis (L.) (Coleoptera: Silvanidae) on kibbled wheat
Journal of Stored Products Research, 1994Abstract Finite rates of population increase (λ) of a pesticide susceptible strain of Oryzaephilus surinamensis (L.) living in kibbled wheat were determined at 20, 22.5, 25, 30, 32.5 and 35°C at 30, 50 and 70% relative humidity (r.h.) using survivorship and fertility schedules, i.e.

Sawtoothed grain beetle (oryzaephilus surinamensis linnaeus) and human ecology
ПЕСТ-МЕНЕДЖМЕНТ, 2021Суринамский мукоед (Oryzaephilus surinamensis Linnaeus) широко распространен по всему миру. Это один из самых опасных вредителей сельскохозяйственной и пищевой продукции, кроме того, он представляет угрозу здоровью людей. Для борьбы с суринамским мукоедом предлагается применение инсектицидных средств и ионизирующего излучения.
