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.

Variation in life history parameters of Oryzaephilus surinamensis (L). (Coleoptera: Silvanidae)

Journal of Stored Products Research, 1989
Abstract Rates of survival and development of immature stages, and survival and fertility of adults of four field populations and two laboratory strains of Oryzaephilus surinamensis (L.) were compared. Population parameters of the field populations were generally similar, although one had a lower fertility rate.

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.

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.

Olfactory and aggregation responses of Oryzaephilus surinamensis (L.) to extracts from oats

Journal of Stored Products Research, 1982
Abstract Rolled oats and pentane extracts of rolled oats were attractive to the adult Oryzaephilus surinamensis (L.) when tested in a Y-tube olfactometer. Pentane and ether extracts of rolled oats caused aggregation of these beetles when tested in a two-choice petri dish bioassay. Responses to crude extracts obtained by 3 different extraction methods

Genetic variability in esterases and the insecticide resistance in brazilian strains ofOryzaephilus mercatorandOryzaephilus surinamensis(Coleoptera: Silvanidae)

Bulletin of Entomological Research, 2010
AbstractOryzaephilus mercatorandO. surinamensisare stored grains and processed food pests, the latter being responsible for major economical losses. Polyacrylamide gel electrophoresis was used to analyse esterase patterns during insect development. Seven esterases, three cholinesterases, two carboxylesterases and two acetylesterases, were identified ...

Malathion for the control of Oryzaephilus surinamensis in stored oats

Journal of Stored Products Research, 1974
Abstract 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

AN EXPERIMENTAL TEST OF FRAGMENTATION AND LOSS OF HABITAT WITH ORYZAEPHILUS SURINAMENSIS

Ecology, 2003
This 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.
