Diversity of loranthaceae and fruit species: case of plantations in rural areas of the city of daloa in Côte d'ivoire

The study aims to know the diversity of Loranthaceae in fruit species associated with crops and to establish their degree of infestation in the plantations in the rural area of the city of Daloa. The inventories by surface and intinerant surveys combined with direct observations were carried out in the plantations. Twelve fruit species being to 8 genera and 7 families were inventoried. They are parasitized by 3 species of Loranthaceae: Phragmanthera capitata, Tapinanthus bangwensis and T. globiferus. T. bangwensis is the most infesting parasite. Among the fruit species recorded, Citrus sinensis (78.92% and 4.46 tufts/plant), Persea americana (73.82% and 5.23 tufts/plant), Psidium guajava (69.69% and 2.55 tufts/plant) and Cola nitida (56.24% and 9.84 tufts/plant) registered elevated pairs of infestation values (rate and intensity). Citrus with 41.67% of the host taxa is the most infested genus. The infestation rate of every fruit trees is of the order of 32.65% for an infestation intensity of 5.67 tufts/plant. For sustainable agriculture, the association of some fruit species with annuity crops under the influence of Loranthaceae should be followed and controlled.
