“…% also after three days with C3). These results are comparable with observations made on the field by Coffi et al (2013) and Konan et al (2014) which had shown that the leaflets of E. oleifera are very unfavorable to the development of the pest. These results correspond according to them, to a different sensitivity against C. lameensis which would be related to the various origins of oil palm trees.…”

Coelaenomenodera lameensis is an insect and the major pest of the oil palm. In case of strong attack, it causes up to 50% loss of production. Larval development of C. lameensis is more pronounced on sensitive palm tree Elaeis guineensis originating from La Mé, Yocoboué and Deli compared to tolerant palm trees Elaeis oleifera originating from Central American. The objective of this work is to study the variability content of polyphenols from different palm trees and their effect on the larvae of C. lameensis. To do this, the extracts from the leaflets of these palms were analyzed by HPLC and tested on larvae of the leaf miner. Considering the results, HPLC analysis has revealed additional peaks polyphenols characterizing trees palm Elaeis oleifera tolerant, the retention time of 22.9, 26.4 and 30.4 min. Furthermore, bio-essays conducted on the larvae of Coelaenomenodera lameensis showed differential mortality of these larvae following the origin, the time and the concentration of applied chemical extracts. Indeed, this result indicates that the molecules in the three characteristic peaks are probably potential polyphenols and are in charge of tolerance to C. lameensis.

“…In C. lameensis, the larva, nymph and internal adult live in galleries and each gallery may contain one or more individuals. This same observation was made by Koua et al (2010), Tano (2012) and Konan et al (2014) in this same insect. Similar results were obtained in Javeta pallida, with the difference that in this beetle, there is generally only one individual (larva or nymph or adult) per gallery, rarely more (Shameem et al, 2016).…”

The oil palm tree is the first source of fatty substances of vegetable origin in the world. However, its cultivation is strongly threatened by damage from Coelaenomenodera lameensis. The present study aimed at promotion a good knowledge of its biology in order to better manage its populations. Thus, some biological parameters of this pest were studied by means of cage breeding (September 2015-December 2017) on an plot ofLa Mé station of National Agronomic Research Center located 30 km North-East of Abidjan in Côte d’Ivoire. The results revealed that the development of C. lameensis passes successively through stages egg, larva, nymph, internal adult and external adult stages. Also, the female lays an average of 137.48 ± 62.04 eggs and the number of individuals gradually decreases from egg stage to adult stage. The average life cycle length was 94.5 ± 7.94 days with a sex ratio of 1.34 ± 0.25 in favor of males. In addition, the mean lifespan was shorter in females than in males with respectively, 103.24 ± 10.25 days and 127.34 ± 21.41 days. All these parameters constitute potential indicators of C. lameensis biology and could help to put in place good strategies for control of its populations.

The edibility of different Elaeis sp. breeding populations present in Benin was tested for the leaf miner Coelaenomenodera lameensis Berti (Coleoptera: Chrysomelidae), a major oil palm pest in Africa. Experiments carried out in sleeves revealed the oviposition capacities of females and the mortality rates for the different developmental stages by comparing the populations found on two breeding populations of Elaeis oleifera (HBK) Cortes, four of Elaeis guineensis Jacquin and four (E. guineensis × E. oleifera) × E. guineensis backcrosses. Females laid their eggs similarly on all breeding populations, with a preference for the E. guineensis La Mé origin. The average hatching rate reached 80% for the La Mé origin as opposed to 28% for the Deli origin. The mortality rates for the larval instars were greater on E. oleifera, on certain backcrosses and on the Deli origin of E. guineensis. Development at the second- and third- larval instars was the most affected, with a mortality rate of three to five times greater than that seen on La Mé. Epidermis and cuticle measurements indicated which breeding populations were suitable or unsuitable for the development of C. lameensis. E. guineensis, with its thin epidermis (12 µm) and cuticle (2 µm), proved to be highly susceptible to C. lameensis attacks. On the other hand, E. oleifera, which is very resistant, exhibited a thicker epidermis (17 µm) and cuticle (4 µm). The breeding populations were thus classified according to the positive or negative influence they exerted on the insect’s egg laying and feeding.RÉSUMÉ. La comestibilité de différents matériels végétaux d’Elaeis sp. présents au Bénin est testée pour Coelaenomenodera lameensis Berti (Coleoptera: Chrysomelidae), important ravageur du palmier à huile en Afrique. Des expérimentations en manchons ont permis de déterminer les capacités d’oviposition des femelles et les taux de mortalité des différents stades de développement (œufs, larves, nymphes et adultes) en comparant les populations observées sur deux origines d’Elaeis oleifera (HBK) Cortes, quatre origines d’Elaeis guineensis Jacquin et quatre Backcross (E. guineensis × E. oleifera) × E. guineensis. Les femelles pondent indifféremment sur tous les types de matériel végétal avec une préférence pour l’origine La Mé d’E. guineensis. Le taux moyen d’éclosion atteint 80% pour l’origine La Mé contre 28% pour l’origine Deli. Le taux de mortalité des stades larvaires est plus important sur E. oleifera, sur certains Backcross et sur l’origine Deli d’E. guineensis. Le développement des deuxième et troisième stades larvaires sont les plus affectés avec un taux de mortalité 3 à 5 fois supérieur à celui observé sur La Mé. Des mesures d’épiderme et de cuticule mettent en évidence l’existence de matériel végétal favorable ou défavorable au développement de C. lameensis. E. guineensis dont l’épiderme (12 µm) et la cuticule (2 µm) sont peu épais se révèle être très sensible aux attaques de C. lameensis. Au contraire, E. oleifera présente un épiderme (17 µm) et une cuticule (4 µm) p...
