We studied the usefulness of wood- and cellulose-based diets for L. africanus Lesne. Three diets were prepared which differed on the base ingredients; wood particles (Diet 1), cellulose powder (Diet 2), and alpha-cellulose (Diet 3). The diets were provided to adult L. africanus and the number of larvae, as well as the number of adults that emerged sex ratio, and body weight of the progeny was determined. Findings indicated similar results for the number of larvae, sex ratio and body weight of the emerged L. africanus fed on each diet. However, the number of adult produced by L. africanus on Diet 3 was significantly lower. The results indicate that the amount of vital nutrients is not the only important factor in selecting a suitable diet for L. africanus because the filler used in artificial diets influences the beetles overall population growth. For the population upon which the diets were tested, Diet 1 and Diet 2 could be utilized to rear beetles in the laboratory. View Full-Text
