“…Recent field reports indicate that populations of the pest are generally low due to successful management (Nébié et al 2016). Yield loss of 80% in mango have been reported in Ghana (Otoidobiga and Atouga 2009), up to 100% in Côte d'Ivoire (Hala et al 2004) and 37% in Senegal (Fall et al 2017). Overall, the pest can cause upwards of 90% damage under high infestation and no control instances (IPPC 2019).…”

Important alien and potential native invasive insect pests of key fruit trees in Sub-Saharan Africa: advances in sustainable pre- and post-harvest management approaches

Fruit production in Sub-Saharan Africa is of paramount importance both socially and economically. Millions of farmers derive livelihoods from mango, avocado, citrus, cashew, and coconut farming, but native and alien invasive species constrain production The region’s capacity to contain invasives is weak due to the absence of national and institutional support systems for early detection, containment, eradication, or management of the pests. Climate change is expected to play a huge role in the influx of more alien invasive species and the shift of ecological requirements of some native species. Though a fair share of pre-and post-management pest management techniques for several insect pests has been developed, adoption and adaptation of the options are limited. Data on economic and social implications are largely lacking, making it challenging to implement informed policy decisions. The existence of the “Strategy for Managing Invasive Species in Africa 2021–2030” promises a paradigm shift in the management of invasives, from reactive thinking to coordinated proactive approaches. The uncoordinated deployment of management measures in the region and the lack of funding, play a negative role in managing the pests effectively. Prospects for enhanced future research are wide, and efforts are currently being channeled to Area-Wide-Integrated Pest Management in a bottom-up approach with stakeholders owning the process. Participatory development of technologies is also taking centre stage, paving the way for increased adoption and adaptation. Postharvest technologies promise to provide the adequate phytosanitary assurance required by countries importing fruit from Sub-Saharan Africa.

“…But the main insect pests are fruit flies, mealybugs and termites [3]. Rastrococcus invadens Williams was the only mealybug species reported as a threat to the mango industry in Burkina Faso [3] [4]. This invasive species was accidentally introduced in West Africa in the 1980s [5].…”

Rastrococus invadens was the only reported mealybug species on the mango tree in Western Burkina Faso. This study aimed at carrying out the inventory and showing the importance and distribution of other mealybug species associated with the mango tree. It was also important to determine the periods of abundance of these species vis-a-vis R. invadens. For this purpose, the density of mealybugs was assessed in three study sites (Toussiana, Bérégadougou and Orodara) in Western Burkina Faso. The observations were made from June 2014 to June 2015 at a frequency of 15 ± 1 days. They focused on 20 leaves (5 leaves/cardinal point) levied on each mango tree. The species identified as Ferrisia virgata Cockerell and Icerya aegyptiaca Douglas were collected from mangos infested by R. invadens representing 98% -99% of the density of the observed mealybug species. The periods of abundance of F. virgata and I. aegyptiaca were respectively the dry season and the rainy season. The effect of temperature, relative humidity and rainfall on the populations of F. virgata and I. aegyptiaca was also discussed. These results highlight the distribution range of F. virgata and I. aegyptiaca worldwide including Burkina Faso. R. invadens was the main mealybug species on mango in Burkina Faso in general and in the Western region of the country in particular.

“…These necroses affect the commercial value of the fruits and induce losses of income for the producers and all the actors of mango sector. Some works concerning fruit flies and incidence of the mango mealybug including control strategies against them were done in Côte d'Ivoire (Hala et al, 2004). However very few researches concerning post harvest anthracnose pathogen of mango fruit have been done.…”

Anthracnose is the most important post-harvest disease of mango caused by Colletotrichum gloeosporioïdes in Côte d'Ivoire. This study was conducted to evaluate the pathogenicity of 5 isolates (CA1, CA2, CB2, CB3 and CK2) of C. gloeosporioïdes. The isolates were obtained from naturally infected fruits of varieties including Brooks (CB2 and CB3), Kent (CK2) and Amelia (CA1 and CA2). The mycelium plugs of each purified isolate were used for a wound or no wound inoculation of Brooks and Keitt mango fruits. The dates of the first lesions appearance with their sizes were assessed. The inoculation without wounds didn't produce any lesion on both varieties. On the other hand, with the wounded method, all the isolates caused lesions on the varieties studied. The first lesions were induced on the 6 th day after inoculation (DAI) on both varieties by isolate CA2. It also produced the largest lesion size on Keitt (3.19 ± 0.39 cm) and Brooks (2.61 ± 0.34 cm). On the opposite, isolate CA1 induced lesions lately with an average at 10.75 and 8.50 DAI, as well as a lower average size of 0.12 ± 0.07 cm and 0.62 ± 0.21 cm, respectively on Brooks and Keitt varieties. Isolates CA2 was the most virulent on the two varieties.
