Fluctuations in Natural Populations of the Leaf miner (<i>Coelaenomenodera lameensis</i>) in Relation to Different Origins of Oil Palm (<i>elaeis</i>sp.) in South Benin

Glitho Centre de Recherches Agricoles Plantes Pérennes (CRA-PP) Institut National de Recherches Agricoles du Bénin (INRAB) Pobè Bénin Centre International de Recherche Agronomique pour le Développement Montpellier France Laboratoire d’Entomologie Appliquée Faculté des Sciences Université de Lomé Lomé Togo.

Preferences of different oil palm crosses in the station of Pobè in Benin were tested on Coelaenomenodera lameensis by monitoring the natural population for 7 consecutive years. Experiments monitoring of developmental stages of the insect were performed on material types elaeis guineensis and elaeis oleifera. Observations were performed every two weeks on leaves of different ranks (25, 17 or 9) depending on the degree of defoliation by counting the different stages of insect development on leaflets. The results showed that the evolution of pest density is a function of species and the origin of the materials being compared. Population densities of different stages of C. lameensis were more abundant in the crosses from Yocoboué where average population indices were higher at all stages of development from early observations. By contrast, in crosses La Mé, Yangambi and Deli, the numbers of larvae, pupae and adults were lower. Among these three crosses infestation was more abundant in La Mé, followed by Yangambi and Deli. E. oleifera is much less or not attacked. The stages of development (larvae and adults) were also differently held in oil palm origins in comparison. The larval population is significantly important during the short rainy season and lesser important during the dry season. These results may contribute to the development of suitable materials for the genetic improvement of breeding tolerant oil palm material to leaf miner.

Towards Sustainable Oil Palm Plantation Management: Effects of Plantation Age and Soil Parent Material

引用

Agricultural Sciences 2020年第1期11卷 54-70页

作者： Georges Kogge Kome Fritz Oben Tabi Department of Soil Science Faculty of Agronomy and Agricultural Sciences University of Dschang Dschang Republic of Cameroon

This study was conducted to generate information required to guide plantation management in relation to replanting on soils derived from different parent materials. Six oil palm estates in coastal lowlands of southwest Cameroon were considered. Oil palm yield data (in t⋅ha−1 of fresh fruit bunch, FFB) and corresponding age of palms (in years after planting, YAP) were obtained for the various estates. In all the estates, average yields were ⋅FFB⋅ha−1 and highly variable. Plantation age, solely, explained between 20% - 58% of the variation in yield. The highest average yields (11.5 t⋅FFB⋅ha−1) were obtained in plantations aged between 9 and 18 YAP and the lowest (4.66 t⋅FFB⋅ha−1) were obtained in old plantations (>23 YAP). Plantations located on volcanic parent materials generally had higher yields compared to those established on sedimentary parent materials. In order to intensify production and increase yields while conserving the environment, one important measure to consider is the replacement of aged palms, and the recommended optimal replanting age in coastal plains of southwest Cameroon should be at most 23 YAP. Estimated mean yields, if aged palms are replanted on time, can increase by 43% - 65%. Additionally, site-specific nutrient management options should be considered in plantation intensification programs.
