Abstract
The oil palm leaf miner, C lameensis is currently the most destructive pest of oil palm in Ghana and other oil palm growing countries in Africa and causes considerable losses in the yield of fresh fruit bunches. Experiments conducted at the Oil Palm Research Institute in Ghana revealed no significant differences (P>0.05) in the duration of the various developmental stages of C. lameensis on five oil palm progenies coded A, B, C, D and E. However, slight variations in the ability of the progenies, to support the development and growth of the oil palm leaf miner were observed. The longest developmental period was on progeny D (100.8 days) and the shortest were on progenies C and E (98.2days). The mean duration of the various development stages were, 18.5 days egg incubation, 46.1 days for larval development, 13.6 days from pupal to external adult and 20.6 days from external adult emergence to egg laying with a total life cycle of 99 days.
