Two mutations in Oryzaephilus surinamensis (L.) (Coleoptera: Silvanidae)

Journal of Stored Products Research, 1986
Abstract Clear eye ( c ) and dark body colour ( d ) mutations in Oryzaephilus surinamensis (L.) are described. The c mutation is phenotypically identical to “pearl” (Blackman, 1966), lacking pigment in the compound eyes and also in the larval ocelli and Malpighian tubules. These structures are deeply pigmented in the wild type.

Nutritional relationships in larvae of Oryzaephilus surinamensis

Journal of Insect Physiology, 1967
Abstract 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.

Die symbiose von Oryzaephilus surinamensis L. (Cucujidae, Coleoptera)

Zeitschrift für Morphologie und Ökologie der Tiere, 1931
1. Oryzaephilus surinamemis L. besitzt in Larve, Puppe und Imago beiderlei Geschlechts vier ovale Mycetome, die vollig isoliert vom Darm in den Fettkorperlappen eingebettet sind. 2 Mycetome liegen ventral beiderseits vom Nervensystem, 2 dorsal schrdg hintereinander uber dem Darm vor der vorderen Enddarmschlinge. 2.

FOOD SELECTION BY ORYZAEPHILUS MERCATOR (COLEOPTERA: CUCUJIDAE)

The Canadian Entomologist, 1976
AbstractAdults of the merchant grain beetle, Oryzaephilus mercator Fauvel, were found most frequently in bran, shelled sunflower seeds, rolled oats, and brown rice in a series of tests of up to 18 different household foods and oilseeds. Walnuts and flaxseed ranked next among the preferred foods. Wide fluctuations in preference occurred with bran, bread

Humidity Response of the Larvae of Oryzaephilus surinamensis (Coleoptera: Cucujidae)

Annals of the Entomological Society of America, 1971
The 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 ...

A pearl-eyed mutation in Oryzaephilus mercator (Fauv.) (Coleoptera, Silvanidae)

Journal of Stored Products Research, 1982
Abstract A pearl-eyed mutation in Oryzaephilus mercator (Fauv.) was observed in a culture of a strain obtained from a cargo of desiccated coconut imported into the U.K. in 1978. The mutation appears as an unpigmented compound eye bordered by an apparently pigmented region which is probably caused by the pigment of the underlying ocular diaphragm ...

Effects of zeolite formulations on the mortality and progeny production of Sitophilus oryzae and Oryzaephilus surinamensis at different temperature and relative humidity levels

Journal of Stored Products Research, 2019
The insecticidal potential of two natural zeolite formulations, Zeocem and Mycostop, was tested against the rice weevil Sitophilus oryzae (L.) and the sawtoothed grain beetle Oryzaephilus surinamensis (L.) on wheat, at the dose rates of 0.25, 0.50, 0.75,

Lysine requirements of larvae of Oryzaephilus surinamensis (L.) (Coleoptera, Silvanidae)

Journal of Insect Physiology, 1961
Abstract Larvae of the saw-toothed grain beetle, Oryzaephilus surinamensis (L.), survived in greater numbers and developed quicker as the concentration of l-lysine in the diet increased from 0 to 1·37 per cent. At higher concentrations the number surviving and the rate of growth decreased.

The demography of Oryzaephilus surinamensis (L.) (Coleoptera: Silvanidae) on kibbled wheat

Journal of Stored Products Research, 1994
Abstract 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.
