Inventaire des lépidoptères des céréales dans les régions de Ghardaïa et de El - Méniâa

Abstract

This study was conducted on butterflies on farms in two regions: the Ghardaïa region and the Mnaia region, through eight stations, from September 2023 to February 2024. On two types of crops (corn and wheat), butterflies were sampled irregularly. The results were analyzed by applying some biodiversity indicators: species richness, relative abundance and frequency of occurrence. The results obtained allowed the identification of 283 individuals, and a total of 4 species of butterflies divided into 3 families were identified in the three study sites: Noctuidae, Nymphalidae and Pyralidae. During our study, the most abundant family was Noctuidae and in September recorded greater butterfly activity. The yellow corncob moth, Helicoverpa armigera, causes pests in corn crops in the Ghardaïa region.
