Experiments showed that consolidation of larvae remaining in rearing trays after the 1st harvest of pupae was economically beneficial in mass rearing Anopheles albimanus Wiedemann. There was no significant difference (P=0.05) in pupal production or insect quality between the different consolidation schemes and the unconsolidated controls. However, there was a significant difference in insect quality between the 3rd pupal harvest and the first 2 harvests. The economics of using only 2 pupal harvests and a consolidation of pupae after the 1st harvest (4:1) is also shown.
