Loranthaceae are hemiparasitic vascular plants that develop on other woody species. They are used in traditional medicine to treat various pathologies. The present study is a contribution to the knowledge of the medicinal potential of Loranthaceae used in care by Agni Sanwi of Aboisso and Maferé, in the South-East of Côte d'Ivoire. Ethnobotanical surveys were conducted with 50 herbalists and 17 traditional healers using semi-structured interviews. Three (3) species (Globimetula braunii, Phragmanthera capitata and Tapinanthus bangwensis) divided into 3 genera used to treat 35 diseases were identified. They have been cited in the formulation of several remedies. Malaria, typhoid fever, diarrhea and fontanelle were the most commonly reported conditions. Leaves and leafy twigs are the main organs used. The decoction has been predominant in the acquisition of remedies. The drink was the most cited as a method of administering treatments. The Frequency of Citations (FC) of the Loranthaceae employed in the care and medicinal Informant Agreement Ratio (med.IARs) of the respondents were determined. T. bangwensis had the highest FC (95.52%) and med.IARs (0.73). The therapeutic potentials of Loranthaceae have been highlighted and deserve to be popularized through complementary phytochemical investigations.

Loranthaceae are parasitic vascular plants that live and thrive at the expense of other woody plants. They proliferate on various woody plants and pose a threat to the host. It seemed important to know the pest species implicated in plantations. The target of this study is to identify Loranthaceae in plantations in periurban areas of Daloa to determine their phenology, to know their ecological habitat and to identify the damage caused to hosts, in order to raise the alarm bell the destructive impact of this plant biodiversity on other woody plants. Surveys and botanical inventory carried out on 25 plantations made it possible to identify three species divided into two (2) genera of which the most distributed on all the plantations prospected was Tapinanthus bangwensis (100% presence). The results of the phenophase observations of the three species showed that they overlap in duration and are not independent of each other. Five major damage was observed. Complete defoliating of host branches (45%) and drying of parasitized branches (32.7%) were the predominant damage observed. Knowledge of the phenology of these parasitic species could be used to develop strategies for the effective control of their spreading at favorable times.

In Côte d'Ivoire, urban agriculture is expanding in several cities due to its proximity to consumers and its financial benefits. In the city of Daloa, several plant species are cultivated as food crops in market gardens. A survey based on semi-structured interviews was carried out among 19 people at 8 market gardening sites. This sector is controlled by functional illiterate persons who are more than 5 years’ experience. Eleven species included in 9 genera and 8 families and grouped into 5 types of vegetables were recorded. Carrot, Cabbage, Courgette, Spinach, Green Bean, Parsley, Lettuce and Tomato were the most grown vegetable. The most represented families were Apiaceae, Asteraceae and Liliaceae. Leafy vegetables (lettuce, cabbage, parsley) were the most grown. Market gardening generates monthly incomes depending on actor, species, and seasons. Thus, this sector provides an important source of income for local populations and deserves support from authorities.
