Food source had a significant effect on development time ofGlischrochilus quadrisignatus(Say) from neonate larva to adult, with the shortest mean developmental time of 41.2 d on multiple-species rearing diet (MSRD)and longest mean of 63.4 d on sap beetle diet (SBD). Pupae that developed on MSRD were heaviest, followed by those on SBD, apple (Malus domesticaBorkh), and tomato (Lycopersicon esculentumMill.). Percentage survival from neonate larva to adult differed significantly among food sources. Survival to adult was highest on MSRD. Females fed on MSRD, SBD, and apple produced significantly more eggs than on tomato. Beetles survived significantly longer on MSRD and apple than on SBD. Highest mortality occurred on tomato. The adult sex ratio on both artificial diets conformed to a 1:1 ratio. However, on natural foods, males were significantly more abundant than females.G. quadrisignatusreared on any food resulted in population increases of from 20.0- to 71.3-fold after each generation. MSRD proved to be the most suitable food for rearingG. quadrisignatus.
