Abstract
The leaf miner, Coelaenomenodera elaeidis (Coleoptera: Chrysomelidae) is a high priority insect pest of the oil palm. The study examined the influence of temperature and rainfall on C. elaeidis abundance in the Okomu oil palm plantation between 2007 and 2009. Climatological data were obtained from the Okomu meteorological station. Pest and weather data were analyzed using multiple linear regressions. Highest mean temperature (33.13 0C ± 1.29) and rainfall (233.73mm ± 176.01) were recorded in 2007. There were significant relationships between adult (0.045) and pupa (0.02). C. elaeidis stages with rainfall and minimum temperature in 2007. Leaf miner predictions were evaluated for the different leaf miner stages using their corresponding model equations. The mathematical relationship between the insect stages (larva, pupa and adult) and weather factors (rainfall and temperature) implies that pest prediction can be made for the different leaf miner stages using their corresponding model equations giving specific values for rainfall and temperature. The variations in the seasonal patterns of temperature and rainfall are of major significance as a cue to timing leaf miner abundance and ensuring effective control. This study recommends control of the C. elaeidis before the onset of the dry season and temperature build up. This improves management of the leaf miner by controlling it more effectively.
