Abstract

The biology of the banana pseudostem borer was studied under ambient temperatures to determine the different developmental stages and the life history of the pest on lakatan banana. The recorded maximum number of eggs laid by thirty females within 48 hours oviposition period was 15 eggs or an average of 0.12 egg/day/female. Mean percent hatchability was 83%. The eggs hatched in 2-3 days. There were five larval recognized by the relatives size of head capsule. The average stadia were as follows: first instar 2.04 days; second instar 1.93 days; third instar 2.3 days; fourth instar 2.95 days; and fifth instar 5.4 days. the mean duration of pupal period was 15.24 days and the total developmental period (from egg laying to the emergence of adult) was 32.12 days. The percentage of survival from egg to adult was 76.5 %. The sex ratio of newly emerged adult was 1 male: 1:3 females.
