Abstract
The present investigation was carried out to study some ecological aspects of the powder-post beetle L. africanus such as the effect of initial sex ratio on infestation, response to colour effect, and effect of light on adult beetle activity. Increasing of males proportional to females, increased the female progeny and vice versa. Females were more sensitive than males to colour effect. Orange colour is the most effective on female activity followed by green, white, red and blue. Darkness had strong effect on the adult beetles, giving higher progeny and shorter duration.
