Various species and varieties of the genus Solanum (Solanaceae) are among the most important market crops produced worldwide. They may be considered as multipurpose crops since leaves and/or fruits are eaten fresh or cooked in various dishes. The increase of garden surfaces and the permanence of gardening have induced frequent outbreaks and diversification of pests and cryptogrammic diseases. In order to improve farmer's capacities in controlling these constraints, the present study assessed diversity, abundance and incidence of fruit pests on Solanum spp. Data collection was conducted in two agroecological zones of southern Cameroon: Okola (Center Region) and Koutaba (Western Region), on three plant varieties from the genus Solanum: Solanum aethiopicum (African scarlet eggplant) with two varieties (jakatu and zong) and Solanum melongena (brinjal eggplant) var. inerme. The study aimed to (1) characterise the community of fruit pests associated with these plant varieties, (2) assess damage due to the main pests and (3) determine their impact on fruit yield. To achieve this, systematic sampling were done by visual observations in experimental gardens set up at the above cited sites. Harvests and incubations of infested fruits allowed identifying 15 insect species, belonging to three orders and 12 families: Lepidopterans with Leucinodes orbonalis, Cryptophlebia leucotreta, Helicoverpa armigera, Chrysodeixis chalcites and Hypolycaena phylippus), Dipterans with Batrocera (Batrocera) dorsalis, Ceratitis (Ceratitis) capitata, Ceratitis (Pterandrus) anonae, Neosilba sp., Atherigona sp. three unidentified species belonging to undetermined genera and Coleopterans with Diplognatha gagates and Formicomus sp.. Among them, H. phyllipus and C. chalcites were absent from Koutaba's samples. Without site considerations, L. orbonalis was the most abundant with higher incidence on fruit production. At Okola, fruit losses on S. aethiopicum var. jakatu, on S. aethiopicum var. zong and on S. melongena var. inerme were 53.8-76.97, 43.65-61.51 and 29.42-46.61% respectively while at Koutaba, they were 49.51-68.57, 33.41-60.23 and 11.68-30.44%. The present study provided baseline data for integrated pest management strategies of Solanum in Cameroon.

“…Despite the publication of several recent important articles on the host range of B. invadens in both East Africa [36,37,43] and West Africa [34,39], much more knowledge is needed on its biology, ecology and behaviour. Particularly, studies are needed on its life history, its spread (adaptive significance of its movements in relation to environmental factors), its biotic and abiotic mortality factors, demographic analysis in function of different hosts and, finally, a modelling system in relation to control strategies.…”

--Introduction. Knowledge of tephritid diversity in Senegal was poor before 2004, so PIP-COLEACP and CIRAD, in collaboration with Cérès-DPV, carried out, in 2004, trapping for preliminary detection of fruit flies in six orchards in the Niayes zone. Materials and methods. We selected three mixed mango orchards and three homogeneous mango orchards in this zone. In each orchard, we used three attractants: Terpinyl acetate (Ter), Trimedlure (Tri) and Torula (Tor). Traps were serviced weekly. Results. We captured 77 642 fruit flies in more than 4 months including mango season; they were represented by 18 identified fly species, including ten Ceratitis, six Dacus and two Bactrocera species. Two very serious pests were identified with the confirmation of Bactrocera cucurbitae (Coquillett) for cucurbit crops and the detection of B. invadens Drew Tsuruta & White for fruit crops. The two most abundant species of Ceratitis were C. cosyra and C. silvestrii. Discussion. We captured more fruit fly species in mixed mango orchards than in homogeneous mango orchards. Bactrocera invadens was also more abundant in mixed orchards, probably because of its polyphagous status. This new invasive species, B. invadens, can have many hosts in mixed mango orchards, enhancing its breeding potential. Conclusion. Effective management to deal with this alien species requires: (i) improvement of basic and applied research; (ii) an effective IPM package; (iii) an area-wide management approach; (iv) a sub-regional effort on the part of researchers, extension services, growers, exporters, farming associations and the different actors in fruit value chains (mainly mango). invadens, peut se développer au niveau de nombreuses autres espèces fruitières autres que le manguier, ce qui lui permet d'accroître ses potentialités de reproduction. Conclusion. Une lutte efficace contre cette espèce invasive requiert (i) l'approfondissement de recherches fondamentales et une recherche appliquée efficace, (ii) un paquet technologique efficace en lutte intégrée, (iii) une lutte menée à l'échelle du bassin de production, (iv) un effort général mené à la fois par les centres nationaux de recherche, les services du développement, les exportateurs, les associations de planteurs et les différents intervenants au niveau des filières fruitières (principalement mangue).

“…En général, les espèces du genre Ceratitis sont présentes avant et au début de la montée en puissance des populations de B. invadens tant dans les pièges qu'au niveau des infestations des fruits échantillonnés (Vayssières et al, 2005). C. cosyra est un ravageur de la mangue très important dans tous les vergers de manguiers de l'Afrique sub-saharienne (Vayssières et al, 2000(Vayssières et al, , 2004(Vayssières et al, , 2005Rwomushana et al, 2008 ;Mwatawala et al, 2009). Il est curieux que nous n'ayons pas eu davantage de dégâts dus à cette espèce avec les fruits ramassés au sol.…”

RESUMELa présente étude avait pour but d'inventorier les espèces de mouches des fruits (Diptera : Tephritidae) inféodées au manguier dans la localité de Malang, située dans la région de l'Adamaoua (Ngaoundéré, Cameroun), en zone Soudano-Guinéenne. Pour cela, nous avons identifié les principales espèces présentes dans le verger grâce à un piégeage de détection d'avril 2008 à avril 2009, et, d'autre part, nous avons cherché à connaître les espèces responsables des dégâts à partir du ramassage des mangues dans le verger. Au total, 83 052 adultes de mouches des fruits appartenant à neuf espèces ont été capturés et huit espèces ont été déterminées. L'espèce invasive Bactrocera invadens Drew Tsuruta & White est la plus abondante dans les pièges (66,55% des captures), suivie de Dacus punctatifrons (Karsch) (29,92% des captures). La troisième espèce par ordre d'importance est Ceratitis cosyra (Walker) (3,38% des captures). Six autres espèces sont présentes mais en très faible effectif (avec au total 0,15% des captures). Les adultes de Tephritidae qui ont émergé des mangues mûres ramassées sous les arbres appartiennent à deux espèces B. invadens (98,5%) et D. punctatifrons (1,5%). Le pic de pullulation de B. invadens coïncide avec celui des mangues arrivées à maturité alors que D. punctatifrons est surtout présent après la période de maturité des mangues. B. invadens est la principale espèce de Tephritidae responsable des dégâts sur mangues à Malang. Les organisations de protection phytosanitaire doivent mettre en oeuvre dans les meilleurs délais des programmes de lutte intégrée afin de pouvoir réduire les dégâts de cette nouvelle espèce invasive en dessous d'un seuil économique de nuisibilité.
