The fruit fly Bactrocera dorsalis Hendel is a major constraint to mango production in Burkina Faso. The objective of this study was to evaluate the performance of two types of food substrates in optimizing the mass rearing of B. dorsalis larvae. For this purpose, 200 eggs of B. dorsalis were divided into four batches of 50 eggs and incubated in Petri dishes containing the different food substrates (Diet 1 and Diet 2). This method was used to evaluate the rate and duration of egg hatching, as well as the development time of the different larval stages. In addition, 1200 pupae divided into four batches of 300 pupae, contained in PVC tubes, were placed inside the rearing cages to monitor the emergence of B. dorsalis. Ten pairs of B. dorsalis were placed in rearing cages and fed with Enzymatic Yeast Hydrolysate and sugar to evaluate the fecundity of female flies and the survival of both sexes. The developmental cycle length in Diet 1 and Diet 2 was 23.03 days and 23.24 days, respectively. Fecundity duration ranged from 57.75 ± 2.29 to 109.81 ± 3.81 days for females from Diet 1 and Diet 2, respectively. The pupal hatching rate varied significantly (P < 0.0001) from 89.12% ± 1.47% to 97.93% ± 0.34% depending on the type of food substrate. Males lived longer than females regardless of food substrate type (60.36 ± 1.84 to 107.10 ± 4.08 days for Diet 1 versus 42.02 ± 1.65 to 87.79 ± 2.27 days for Diet 2). Both food substrates tested were favorable to the good development of B. dorsalis, but the spawning index was 4 times higher with Diet 1. Most of the components of Diet 1 are available on the local market and are cheaper. Thus, we recommend the use of Diet 1 for B. dorsalis larvae mass rearing.
