“…EQ = H'/log2N, this index varies from 0 to 1. To describe the ecological importance of host families within each itinerary as well as for the total flora, the family importance value index (FIV) (Mori et al, 1983), was also calculated: FIV = family relative diversity + relative density + relative dominance Family relative diversity = (number of species in a family/total number of species) × 100 Relative density = (number of trees of the species or family/total number of trees) × 100 Relative dominance = (basal area of a species/basal area of all the species) x 100 The parasitic species were identified on the field and confirmed by other authors' surveys (Dibong et al, 2008;Soro et al, 2010;Dibong et al, 2012;Azo'o et al, 2013;Koffi et al, 2014).…”

“…These parasitic species which have not been sufficiently studied and vulgarized by research foundations constitute a real threat to trees in home gardens (Dibong et al, 2008). In East Cameroon, Theobroma cacao, Coffea robusta, Dacryodes edulis plantations and coastal gardens along roads created by forest exploitation are major Loranthaceae targets (Dibong et al, 2012;Azo'o et al, 2013).…”

There is an increasing interest in parasitic plants and infectious disease community ecology in intertropical regions. The study examined the floristic diversity of Loranthaceae family and their potential host species in the ecoregion of Diamare plain in Cameroon. Reasoned sampling method was performed and experimental device consisted of 02 main treatments (Diamare and Mayo-Kani divisions), 08 secondary treatments (councils) and 32 replications (villages), with four (04) villages per council. We used itinerary botanical survey method of 1000 m x 20 m in each village, totalizing 64 ha and all parasitic plants and their potential hosts were inventoried. A total of 11 645 ligneous individuals was inventoried in the Diamare division, distributed within 65 species, 44 genera, and 22 Families. In Mayo-Kani division, a total of 16 645 ligneous individuals were inventoried, distributed in 58 species, 41 genera and 19 families. There was a significant difference between the two divisions in terms of individuals (p < 0.001). In total, nine parasitic plants of the Loranthaceae family were inventoried, with five species identified at the level of species (55.55%) and four species at the level of genera (44.44%): Agelanthus dodoneifolius (DC.) Polh. and Wiens, Tapinanthus globiferus (A. Rich.) Van Tiegh., Tapinanthus oleifolus (JC. Wendl.) Danser; Tapinanthus voltensis Van Tiegh. ex Balle; Tapinanthus ophiodes (Sprague) Danser, Tapinanthus sp1., Tapinanthus sp2., Tapinanthus sp3. and Phragmanthera sp. Agelanthus dodoneifolius, Tapinanthus globiferus and T. ophiodes recorded a weak parasitic specificity (PSp = 81.39%; 72.09% and 30.23% respectively). Combretaceae and Mimosaceae families showed the greatest number of sensitive host species to Loranthaceae infestation (20.89% and 16.27% respectively). There was no significant difference between parasitic specificity of Loranthaceae and parasitic sensitivity of host species (p > 0.05), and both were positively correlated (r = 0.96). Efforts are required to control the development of Loranthaceae in sudano-sahelian zone especially in ecosystem plantations.Keywords: Floristic diversity, Loranthaceae, host species, Diamare plain, Cameroon

The present study was carried out in order to identify the ant fauna and her potential role as auxiliary of an agricultural system based on cocoa trees leeched by Loranthaceae, in Nkolbisson neighborhood in Yaoundé (Cameroon). The work was conducted from May to September 2015. An inventory of all woody species and the associated ant fauna was carried out beforehand, followed by an inventory of the ant fauna associated couples Theobroma cacao/Loranthaceae during periods of non-flowering, flowering and fruiting Loranthaceae. We inventoried a total of 187 plants of which 44 (23.53%) were parasitized by flowering-shrub epiphytes (Loranthaceae). Theobroma cacao (cocoa) appeared to be the most abundant species (122 plants) followed by Dacryodes edulis (16 safou trees) and Mangifera indica (15 mango trees). Three species of Loranthaceae were identified: Tapinanthus preussii (Engler) Van Tieghem and Phragmanthera capitata (Sprengel) S. Balle which both attack Theobroma cacao (cocoa tree) and Tapinanthus bangwensis (Engl.et. Krause) Denser which attacks mainly forest type trees. Five sub-families of ants (Pseudomyrmicinae, Dolychoderinae, Ponerinae, Formicinae and Myrmicinae) divided into 16 genera and 35 species were recorded throughout the agrosystem. Tetramorium acculeatum has emerged as the most dominant ant species on both T. preussii and P. capitata. Monitoring of the ant foraging activity during flowering and fruiting Loranthaceae shows they participate in the flowers fall.
