The present study was carried out in order to identify the ant fauna of cocoa fields leeched by Loranthaceae, genus Phragmanthera in Nkoemvone seed farms in the South region of Cameroon. The collection of ants was conducted between November 2013 and January 2014. A total of 15 ant species divided into two sub families (Formicinae and Myrmicinae) have been identified, the subfamily of Myrmicinae being the most represented with 8 genera and 13 species. Fourteen of the 15 ant species harvested, were found on infested cocoa trees. Tetramorium aculeatum has emerged as the most abundant ant species on infested cocoa trees with an index of Berger-Parker dominance equal to 0.32 and 0.34 for cocoa parasitized by Phragmanthera capitata and Phragmanthera nigritana, respectively.
Key words: Ants, inventory, cocoa plants parasitized, Loranthaceae, Cameroon.
