Abstract

Twelve oil palm accessions were screened to find the level of resistance against invasive rugose spiraling whitefly, Aleurodicus rugioperculatus Martin. From the overall seasonal data it was found that among all the tested 12 accessions, EC 869413 was found to be less infested with rugose spiraling whitefly and the accession EC 869395 was found to be heavily infested. All the other tested accessions EC 869399, EC 869412, EC 869408, EC 869409, EC 869397, EC 869407, EC 869414, EC 869404, EC 869406 and EC 869403 were found to have more or less similar infestation. Among the three locations of leaf/frond, the pest population of RSW was found highest at the tip leaflets of frond when compared to base and middle leaflets. Amongst the direction, southern side leaves were recorded with highest population RSW.

Conclusion

From the above investigation, it was concluded that selection of oil palm accession EC 869413 in crop improvement programme enables the breeder to develop a promising variety against RSW as it recorded with low pest incidence.
