Article Reference Diversity and assembly composition of arboreal ants in a west African humid forest-savannah mosaic
In the tropical forest-savannah mosaic of Lamto Reserve in Ivory Coast ants play an important role in the biodiversity conservation. This work aimed to explore the structure and composition of the arboreal ant assemblages in a forest-savannah mosaic located in central Côte d'Ivoire. Ants were collected by baited trap (Protein bait: tuna and sugar bait: sweet milk) and beating of low vegetation. During the entire sampling campaign, 59 ant species belonging to 18 genera and five subfamilies (Formicinae, Ponerinae, Myrmicinae, Dolichoderinae and Pseudomyrmecinae) were recorded. The mean ant species richness of shrub savannah (SS) was significantly lower than of both forest island (FI) and forest gallery. Likewise, a significant difference was observed for species composition when comparing the arboreal ant communities of SS, gallery forest and FI.

Article Reference Can habitat characteristics of a West African forest-savanna mosaic landscape model bee community composition?
Bees are vital to both ecosystems and humans worldwide; supplying a range of key support facilities for the successful breeding of the majority of flowering plants. The aim of this study was to assess the bee species composition in a Sudano-Guinean savanna zone and determining the impact of a set of environmental parameters influencing this species composition in four habitat types. Sampling was carried using yellow pan traps protocol. A total of 846 bees belonging to 3 families, 25 genera and 52 species were collected. The largest number of bee individuals was found in the Apidae family. The most abundant species was Hypotrigona sp. The highest bee species and number of individuals was recorded in the shrubby savanna. Bee species diversity and abundance were found closely correlated with the plant diversity. Gaining a better understanding of the factors influencing bee community dynamics in the given landscape can provide valuable information for conservation efforts, habitat management and help identifying species which ones could be domesticated.

Article Reference FIRST RECORD OF FIVE ANT SPECIES (HYMENOPTERA: FORMICIDAE) FROM RWANDA
Ant studies conducted in Rwanda have reported a total of 105 ant species. However, this is an underestimation of the total ant richness since Rwanda is in a region rich in biodiversity. To fill the gaps, ants have been sampled in planted forests, coffee plantations, and different other land use types since 2017. Specimens have been collected using pitfall traps and hand collection, digitized, and identified to subfamily, genus, and species level. Results indicated that five ant species were found in Rwanda for the first time. These are Camponotus acvapimensis, Camponotus schoutedeni, Camponotus sericeus, Odontomachus assiniensis and Tetramorium sericeiventre. Specimens are deposited at the Royal Belgian Institute of Natural Science and the Rwanda Ant Collection. We recommend more ant studies focussing on their mode of living. This will result in more ant species newly recorded in the country and possibly new to science.

Article Reference Assessing the influences of bee’s (Hymnoptera: Apidae) floral preference on cashew (Anacardiacae) agronomics performances in Côte d’Ivoire.
This study aimed to assess the influence of bees’ floral preference on cashew agronomics performances in Côte d’Ivoire. Therefore, a sampling design with a total of 40 cashew trees preferred by bees and 40 trees that were not preferred by bees was established in 4 main producing regions. In addition, bees’ foragers and agronomics performances of trees were sampled. As results, a total of 46 bee’ species with a foraging activity of 4±0.32 visits per minute were observed. Apis mellifera (60% of visits, with 2.27±0.17 of visitors per minute) followed by Meliponula bocandei (23% of visits with 0.91±0.18 of visits per minute) contributes significantly to the reproduction of cashew trees, compare to the 44 other bees’ species (17% of visits; with an activity of 0.69±0.03 of visitors per minute). The preferred trees recorded 40.54±0.57 kg of nuts per tree, with 18.39±0.48 fruits per inflorescence, including 37.12±0.4% of useful kernel per raw nut (yield ratio of 65.45±0.66 pound of useful kernel). Conversely, the non-preferred trees obtained 5.24±0.44kg of nuts per tree, with 1.7±0.21 fruits per inflorescence, including 28.69±0.65% of useful kernel per raw nut (50.6±1.15 pound of useful kernel). Hence, the foraging preference of these two Apidae significantly increased the fruiting rate (83.7±0.01%), the yields (87.08±0.0%), and the kernel rate (22.68±1.76%) in raw cashew nuts. Based in these results, we suggest the foraging preference of Apis mellifera as good indicator of high-yielding cashew plants. Moreover, we suggests combination of apicultural and meliponicultrual in cashew farming to boost the yields and farmers livelihoods.
