oa Journal of the Entomological Society of Southern Africa - Aspects of the ecology and behaviour of Eremnus cerealis Marshall (Coleoptera: Curculionidae). 2. Laboratory studies on the effects of light, temperature and humidity
The response of adult beetles to light, temperature and humidity was investigated. Evidence is presented that the optimum combination of these environmental factors is a moderately high temperature (ï¿½25ï¿½C), moderately high humidity (ï¿½80% R.H.) and darkness. It was found that darkness is the dominating factor, which results in this species being nocturnal, and that a high humidity has a marked influence on its reactions.
