Rearing Chrysomya megacephala on artificial diets composed of varying concentrations of albumin

Abstract

Larvae of the blowfly Chrysomya megacephala were reared on an artificial diet composed of five different concentrations of albumin (2, 4, 6, 8 and 10%) and the control group was fed on putrid bovine meat. No larvae developed in the 2 and 10% albumin concentrations. The period from newly hatched larvae to adults reared on 4, 6 and 8% albumin was 13.1, 13.1 and 13.6 days, respectively, whereas for the control group, it was 11.2 days. Concentrations of 4, 6 and 8% albumin proved viabile for larval periods of 29.3, 44.0 and 57.3%, respectively, whereas for the control group, it was 77.3%. Pupal viability was 77.3, 36.4 and 83.7%, while for the control group, it was 84.5%; the newly hatched larvae to adult viability was 21.3, 16.0 and 48.0%, respectively, and for the control group, it was 65.3%. © 2009 Tecpar.
