Growth and Development of the Lesser Mealworm, Alphitobius diaperinus (Panzer) (Coleoptera: Tenebrionidae) on Cereal Flours

Mozaffar Hosen, Ataur Rahman Khan and Mosharrof Hossain

Abstract

The effect of different cereal flours, e.g. wheat, barley, corn and rice flours on the lesser mealworm, Alphitobius diaperinus (Panzer) has been worked out. Cereal flours reduced the growth of all the developmental stages of the beetle. The pupal and adult recoveries (%) were also lowered, and the larval and pupal durations were lengthened in the tenebrionid when grown on cereal flours. The fecundity and egg viability (%) of A. diaperinus were also significantly reduced when reared on these flours.
