Preliminary data on the distribution and damage of the community of granivorous pest birds of sorghum (Sorghum bicolour (L.) Moench) (Korhogo, Côte d’Ivoire)
Abstract
Sorghum (Sorghum bicolour (L.) Moench), a cereal rich in protein, is cultivated by the people of northern Côte d’Ivoire as a staple food and for income. However, because of the important losses due to birds, the culture of this strategic speculation is neglected. In order to better understand the impact of these pests and improve food security, a study was carried out from June 2017 to December 2017 on the experimental site of the University Peleforo Gon Coulibaly in Korhogo (Côte d’Ivoire). Forty sessions of direct observations with the binoculars of the avifauna were carried out from seedlings to harvest, and their damage was identified. A total of 2,065 birds belonging to four orders, nine families and 16 species have been identified. Bird diversity was highest during the milky panicle stage. The primary pests in sorghum cultivation were Ploceus cucullatus (Muller, 1776), Francolinus bicalcaratus (Linné, 1766), Psittacula krameri (Scopoli, 1769), Poicephalus senegalus (Linné, 1766) and Crithagra mozambica (Statius, 1776). Three categories of pest birds were determined based on damage: seedling predators, panicle seed depredators and panicle cutters. The phenological stage of sorghum cultivation has influenced the distribution of pest birds. To ensure the well-being of vulnerable rural women’s communities dependent on this speculation, these data must serve as a scientific basis to address the fight in order to reduce the impacts of pests and thus, increase production and fight poverty.
