Abstract :
The leaflet miner Coelaenomenodera minuta is the main pest of oil palm in the south-west region of Cameroon. A 12 months study of spatio-temporal distribution was carried out on young and mature industrial plantations of 40 ha each at Tiko Benoe palm estate in the south-west region of Cameroon. The pest infestation (larvae and adult) distribution revealed the endemic existence of C. minuta in the mature oil palm plantation. Relative null pest infestations were recorded from the young plantation. Three infestation peaks were observed. Monthly significant difference of C. minuta infestation was also recorded. The highest number of insects captured (117.3 per tree) was in December. In addition, negative and relatively significant correlation was observed between monthly cumulative rainfall days and captured C. minuta individuals. These results can help to improve the conception and the implementation of an efficient control strategy against the pest.
