Determination of larval instar of Bactrocera Papayae (Diptera : Tephritidae)on Guava, Psidium Guajava, Linn. based on Morphometric characters

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...
