Abstract:

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.
