Published on:

A study of the life-cycle of Biosteres persulcatus Silvestri, a larval parasitoid of (Bactrocera (B) sp. near Bactrocera dorsalis A), was conducted in the laboratory (26.5°C ± 1.5°C). There are 4 larval stages as indicated by the sizes of the mouthhooks. The first larval moult occurred in the newly-formed puparium of the host. The entire developmental period from egg to adult emergence for male and female was 16.3 ± 0.80 days and 17.1 ± 0.80 days respectively. The average reproductive capacity during the life span was 67 ± 3.5 eggs.
