Morphometric characters such as length and width of the Bactrocera papayae larvae could be used to determine the larval instars at their immature stage. Observation in this study indicated that B. papayae underwent three larval instars. The duration for the first instar, second and third instar was 4, 4 and 7 days respectively. There was a significant difference in the length and width within larval instars of B. papayae . After hatching, the length of the larvae was 1.04 mm and the longest… Expand
