The Neotropical invasive plant Chromolaena odorata R.M. King and H. Robinson (Asteraceae) is a serious weed in West and Central Africa and two biological control agents that have been introduced into West Africa to help reduce its impacts on agriculture and biodiversity, have established. The stem-galling fly, Cecidochares connexa (Macquart) (Diptera: Tephritidae), has spread widely across West Africa since its release in only Côte d’Ivoire, occurring in six countries. This study aimed to investigate whether the gall fly had spread further across West Africa and into Central Africa. Here, we surveyed C. odorata for C. connexa galls in Cameroon between October 2018 and October 2020, along roadsides, on farms, residential areas, and abandoned plots, encompassing various vegetation types. Additional surveys were conducted across four countries (Ghana, Togo, Benin Republic and Nigeria) in West Africa that we considered the probable pathway for the spread of the gall fly into Central Africa. Cecidochares connexa was present at five of the six locations surveyed in Cameroon, albeit in varying abundance. In Africa, these findings represent the first-ever report of C. connexa outside of West Africa. In West Africa, we recorded significant expansion in the geographic range of C. connexa, as reflected in the absent-present record of C. connexa in two locations in Nigeria and one in Ghana, as well as its occurrence in all locations surveyed in Benin Republic and Togo. Clearly, Ghana, Togo, Benin Republic and Nigeria served as the dispersal pathway of C. connexa from the release sites in Côte d’Ivoire into Cameroon, covering over 2,300 km. Following the spread and establishment of C. connexa into Cameroon, we anticipate that it will continue to spread further into other parts of Central Africa which are climatically suitable. Cecidochares connexa is currently the only biological control agent for C. odorata in Central Africa. Given that it has significantly reduced populations of C. odorata in other countries where it has established, it is expected to have a similar impact in Central Africa.

The Impact

Abstract Writing about Zophopetes cerymica (which they considered more common) and P. laufella combined, Mariau and Morin (1974) state that attacks can be on palms of all ages, including young palms recently planted out. At this age, defoliation of the plants delays their subsequent development. Outbreaks on older trees are rarer, and the damage often less important; these attacks are generally localized at the edge of plantations. Mariau et al. (1981) add that the highest fronds are the most often damaged. Herder et al. (1994) refer to regular outbreaks of P. laufella on oil palm in southern Côte d'Ivoire. There are no more substantive reports on the impact of the feeding damage by these hesperiids.

Palmier À Huile

Côte d'Ivoire is the main African exporter of palm oil in ECOWAS. In order to maintain its production, many practices such as the use of mineral and organic fertilizers are necessary. The general objective of this study was to compare the development of oil palm seedlings on five (5) different substrates consisting of potting soil, cow dung, and decomposing palm fibers. The results on the count of dead seedlings showed a low mortality rate on the 100 % potting soil substrate. Evaluation of some morphological parameters revealed better leaf growth in length, a large number of leaves, better fresh weight, larger diameter and better green color of the chlorophyll-rich leaves in the evolved seedlings on the substrates of 50 % potting soil, 25 % cow dung, and 25 % palm fiber, except for the 100 % potting soil. It would be advisable to use cow dung and palm fiber substrates for better development of the oil palm in the pre-nursery. La Côte d’Ivoire, est le principal exportateur africain d’huile de palme au niveau de la CEDEAO. Pour maintenir sa production, de nombreuses pratiques telles que l’apport de fertilisants minéraux et organiques sont nécessaires. L’objectif général de cette étude était de comparer le développement des plantules de palmier à huile sur cinq (5) substrats différents constitués du terreau, de la bouse de vache et de fibres de palmier en décomposition. Les résultats sur le dénombrement de plantules mortes ont montré un faible taux de mortalité au niveau du substrat constitué uniquement du terreau 100 %. L’évaluation de certains paramètres morphologiques a révélé une meilleure croissance des feuilles en longueur, un nombre important de feuilles, un meilleur poids frais, un gros diamètre et une meilleure couleur verte des feuilles riches en chlorophylle chez les plantules évoluées sur les substrats de 50 % de terreau, 25 % de Bouse de vache et 25 % de fibre de palmier, à l’exception des 100 % de terreau. Il serait bon de constituer des substrats à base de bouse de vache et de fibre de palmier pour un meilleur développement du palmier à huile en pré-pépinière.
