Abstract
This study was conducted in the Korhogo region in an age gradient of mango orchards. The goal was to assess diversity and determine the influence of the environment on the composition of these organisms. Sampling was done using pitfall traps, threshing and manual collection. A total of 82 ant species were sampled on all plots. The cultivated plots are richer in ant species than the natural environment. Of the three (3) sampling methods, the Manual Collection proved to be more efficient (eff = 79.52%), followed by threshing (eff = 75.15%) and finally the least effective trap pit (eff = 73.39%). The number of individuals of the species varies according to the environment. The highest value was obtained in the young plot (485 individuals), followed by the intermediate plot (478 individuals), then the older plot (426 individuals) and finally the control plot (320 individuals). The species Camponotus acvapimensis was harvested mainly with 159 individuals. On the other hand, the species Lepisiota sp.1; Camponotus rufigenis, Camponotus sericeus and Oecophylla longinoda were specifically harvested in the control, young, intermediate and aged plots, respectively.
Highlights
Native to the Indo-Burman region, the mango tree (Mangifera indica) is one of the most cultivated fruit species in the world, Vanniere et al, (2013) [1]
For the two (2) habitats, 82 species of ants were collected belonging to 5 sub-families (Table 1): Dolichodorinae, Dorylinae, Formicinae, Myrmicinae and Ponerinae They are divided into 33 such as Tapinoma, Technomyrmex, Aenictus, Dorylus, Camponotus, Lepisiota, Oecophylla, Paratrechina, Plagiolepis, Nylanderia, Atopomyrmex, Cardiocondyla, Carebara, Cataulacus, Crematogaster, Messor, Monomorium, Myrmicaria, Pheidole, Tetramorium, Leptothorax, Trichomyrmex, Anochetus, Bothroponera, Brachyponera, Euponera, Hypoponera, Megaponera, Mesoponera, Odontomachus, Tetraponera, Lioponera, Paltotyreus Twenty two (22) species of ants are common to these environments
This study on the myrmecological fauna of the Korhogo region was conducted in two different environments and mango orchards following an age gradient
Summary
Native to the Indo-Burman region, the mango tree (Mangifera indica) is one of the most cultivated fruit species in the world, Vanniere et al, (2013) [1]. They help to limit deficiencies, especially in vitamin A deficiency thanks to its high vitamin A and vitamin C content, Rey et al, (2004) [2]. Mango occupies a prominent place in the economy of West Africa [4] in general, and in Côte d’Ivoire in particular where it is the third export fruit after banana and pineapple [5]. Mangrove farming provides employment and contributes to the fight against poverty [7] It is heavily under the threat of pests, especially Tephritid flies that attack fruit, causing huge losses in production, N’dépo et al, (2009) [8]
