Damage by the oil palm leaf miner C. lameensis has been observed in all oil palm growing countries
in Africa causing wide spread defoliation and result to considerable reduction in the yield of fresh fruit bunches
(ffb). The understanding of the susceptibility levels of different oil palm progenies to the oil palm leaf miner
C. lameensis become highly imperative in the development and incorporation of host plant resistance in the
integrated pest management strategy for the management of the oil palm leaf miner. By means of no-choice
destructive sampling field experiments, differences in the population levels of the various stages of
development and the assessment of damage caused by larval feeding were studied. All the five progenies were
averagely susceptible to damage caused by the larvae of C. lameensis. No significant differences (p>05) were
observed in the assessed parameters such as percentage egg laid, adult survival in cages, egg hatching, larval
and pupal survival on the progenies. However, progeny D supported the least mean population (45.9%) of the
larva, pupa and adults of C. lameensis with consequent slight damage of 25%. Progenies C, B and A followed
in that order. Progeny E supported the highest mean population of the insect (54%) and suffered the highest
damage of 37.4%. The slight variation observed suggests potential differences in the genetic make up of the
palm. This can create an opportunity for incorporating host plant resistance for the development of an
integrated management strategy for the oil palm leaf miner.
