Inventory of refuge plants of <i>Recilia mica</i> Kramer (Homoptera, Cicadellidae), blast disease vector in oil palm nursery (<i>Elaeis guineensis Jacq.</i>

Abstract

Blast is the most important disease in nursery of palm tree in West Africa. The mycoplasm responsible of this disease is transmitted by the vector Recilia mica KRAMER (Homoptera, Cicadellidae). The aim of this study was to determine R. mica KRAMER plants reservoirs. To achieve this objective, an inventory of the flora frequented by this insect was carried out around two selected plots including a palm tree nursery and a plantation. In total, 14 plants were identified around the nursery and 15 plants around the plantation. Some plants have been registered in both environments. Plants considered refuges for R. mica in this study were Digitaria horizontalis, Pueraria phaseoloides, Panicum maximum, Oldemlandia herbacea, Ageratum conyzoides, Ipomea eriocarpa, Eleusine indica. Furthermore, this study showed that the Recilia mica frequents more plants of the Poaceae family compared to other plant families. This study should be continued to study the reproductive biology of R. micaKeywords: Oil Palm tree, Blast disease, Recilia mica, refuge plants.

Role of wild mammals in traditional medicine and mystic practices in the province of Oubritenga, Burkina Faso

“…In Ethiopia, it's 18 different diseases that have been listed. (Yirga et al, 2011). This high number of diseases proves that populations conserve their traditional knowledge despite the effectiveness of modern medicine.…”

“…In many African countries, studies have proved the utilization of wild animals and plants in traditional medicine (Yaokokorebeibro et al, 2010;Nasi et al, 2011;Djagoun et al, 2012;McNamara et al, 2016;Ajagun and Anyaku, 2017;Djagoun et al, 2018 ;Yolidje et al, 2020). In Africa, traditional medicine is one of the richest cultures that people have developed, conserved and passed on from one generation to another (Rivière et al, 2005).…”
