“…From 2007 to 2012, the WAFFI project (IITA-CIRAD project) developed a comprehensive fruit fly IPM package including sanitation activities with bait sprays containing GF-120 [38], and important biological con- trol options with weaver ants [39,40] and parasitoids [41,42]. All these control measures are compatible with each other.…”

-Introduction. Losses in West African commercial mango orchards due to fruit fly infestations have exceeded 50% by the middle of the crop season since 2005, resulting in considerable income loss for the growers. Materials and methods. In 2009, weekly monitoring of adult fruit fly species of economic significance was carried out in eight West African countries at 12 sites across five agroecological zones: (i) Humid Forest, (ii) Guinean savanna, (iii) Southern Sudan, (iv) Northern Sudan, and (v) Sahelian. Trapping was performed using methyl eugenol and terpinyl acetate in 288 Tephritraps, targeting Bactrocera invadens and Ceratitis cosyra. Results. The data showed that B. invadens was present throughout the year in the Forest zone, abundant for 7 months, with a peak in May at the end of the mango season, C. cosyra being totally absent. In the Guinean savanna zone, B. invadens was abundant for 6-7 months, with a peak at the beginning of June coinciding with the season, with a few C. cosyra. In the Southern Sudan zone, B. invadens was abundant for 6 months, with a peak in mid-June during the season, C. cosyra peaking in April. In the Northern Sudan zone, B. invadens was abundant for 5 months, with a peak at the end of June at the end of the season, C. cosyra peaking in May. In the Sahelian zone, B. invadens was abundant for 4 months, peaking in August during the season, C. cosyra peaking just before. These preliminary results showed that the exotic species, B. invadens, was present at high levels [mean peak of 378 flies per trap per day (FTD)] in all agro-ecological zones, while the native species, C. cosyra, preferred the drier zones of West Africa, with lower population levels (mean peak of 77 FTD). Conclusion. Detection trapping of male flies with parapheromones is a useful indicator of field population levels and could be used to deploy control measures (IPM package) in a timely manner when the Economic Injury Level is reached. Control strategies for these quarantine mango fruit fly species are discussed with respect to agro-ecological zones and the phenological stages of the mango tree.West Africa / Mangifera indica / fruits / exports / Bactrocera invadens / Ceratitis cosyra / agroclimatic zones / plant developmental stages Dynamique annuelle des populations de mouches des fruits du manguier en Afrique de l'Ouest: aspects socio-économiques, phénologie de l'hôte et implications pour leur gestion.Résumé -Introduction.

Soil effect on polyphenols content and antioxidant capacity of new hybrid variety of cocoa from Côte d’Ivoire

Polyphenols have gained much interest recently due to their antioxidant capacity and possible benefits to human health. Cocoa (Theobroma cacao) is a rich source of polyphenols and has higher antioxidant activity than teas and red wines. Cocoa and its derived products contain different types of polyphenols and possess different levels of antioxidant. New hybrids called "cocoa mercedes" have been developed in Côte d'Ivoire for their precocity of production and an improved yield per hectare. The aim of this study is to assess the polyphenols content and antioxidant capacity of these new hybrids in correlation with their geographical sources. Crude extracts were obtained from freeze-dried beans and juice of cocoa in 80% methanol. Polyphenols were measured using the Folin-Ciocalteu's assay and antioxidant capacity by ORAC assay. Total extractable polyphenols were important with almonds followed by fermented juice and Abengourou gave the highest polyphenol content. Antioxidant capacity of almonds was found significantly higher than the other cocoa samples. Abengourou provided the best antioxidant capacity in comparison with other production areas of cocoa such as Adzope, Divo and Yamoussoukro. Effects of geographical sources could influence the polyphenol content and antioxidant capacity of cocoa.

“…Being generalist predators, Oecophylla spp. can significantly reduce the abundance of several insect pests of tropical crops (Adandonon, Vayssières, Sinzogan, & Van Mele, 2009;Peng & Christian, 2004;Peng, Christian, & Gibb, 1995;Peng, Christian, & Reilly, 2011;Way & Khoo, 1989). Furthermore, Oecophylla ants are targeted as mini livestock for sustainable protein production, as they are used as food by humans and animals (Cèsard, 2004;FAO report, 2013;Offenberg, 2011;Sribandit, Wiwatwitaya, Suksard, & Offenberg, 2008;Van Itterbeeck, Sivongxay, Praxaysombath, & Van Huis, 2014).…”

The predatory efficiency of African weaver ants Oecophylla longinoda and their utilisation in protein production is a function of ant abundance. Reliable control of insect pests in tropical crops is achieved when ant populations are constantly high. Transplanted populations of weaver ant colonies containing egg-laying queens are more stable than those without. Achieving such stability through collection of colonies established in the wild is usually difficult because of uncertainty in locating the nest containing the egg-laying queen. In this study, we investigated four methods that may be used to collect mated queens that subsequently can be used to stock ant nurseries. The catch efficiencies of (1) leaf traps, (2) paper traps (both types providing a refuge for founding queens), (3) random search for queens and (4) light trapping were compared. Light trapping was the most efficient way to collect queens followed by leaf traps, random search and, last, paper traps. Light trapping and random search, though, required the presence of a person throughout the ant's mating season (several months), whereas this was not required when using leaf and paper traps.
