Abstract
A multiple-species diet for sap beetles with rearing procedures is described. This diet can be used to rear 11 species of sap beetles belonging to five genera in the Nitidulidae: Carpophilus brachypterus (Say), C. hemipterus (L.), C. lugubris Murray, Lobiopa undulata (Say), Phenolia grossa (F.), Stelidota geminata (Say), S. octomaculata (Say), S. ferruginea Reitter, Glischrochilus quadrisignatus (Say), G. fasciatus (Olivier), and G. sanguinolentus (Olivier). Under laboratory conditions, generation times (egg to adult) ranged from 27 to 50 d, and survival (egg to adult) was 40–79% among the above species. Fecundity of all species was high except among G. fasciatus and G. sanguinolentus. Large numbers of known-age beetles can be obtained by using this method.
