Lysine requirements of larvae of Oryzaephilus surinamensis (L.) (Coleoptera, Silvanidae)
Journal of Insect Physiology, 1961Abstract 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 response of Oryzaephilus surinamensis (L.) (Coleoptera: Silvanidae) to water
Bulletin of Entomological Research, 1983AbstractExperiments were carried out to determine whether Oryzaephilus surinamensis (L.) was attracted to water on a wick suspended in an arena. When insects were preconditioned at 25, 50, 75 or 100% RH, they were attracted to the water source. Those preconditioned at 50% RH gave the greatest response and those preconditioned at 100% RH, the least ...
