Entomofauna of cashew inflorescences (Anacardium occidentale L., 1753) in the Bagoué region of northern Côte d’Ivoire
Abstract
In Ivory Coast, several agronomic research works are conducted to improve the production of cashew trees. However, very few studies have been devoted to pollinating insects. This study aims to identify the insects visiting the inflorescences of the cashew tree in order to improve the fruit setting of this plant. To do this, insects visiting the flowers were observed and then captured 4 times a month from December 2021 to April 2022 during the flowering period. Insects were captured using entomological netting in the three departments of the Bagoue region throughout the flowering period. To do this, before flowering, thirty (30) cashew trees of the same diameter were randomly selected in each orchard and marked with a ribbon. The results indicate the presence of 53 insect species belonging to 25 families and 7 orders on cashew inflorescences. The orders Hymenoptera, Diptera, Heteroptera and Lepidoptera are the most diverse in each department. In terms of family taxonomy, the Apidae, Megachillidae, Hallictidae and Noctuidae families are the richest in species in these localities. Regarding abundance, 25,035 specimens were collected. The order Hymenoptera (85.48%), the family Apidae (68.64%) and the species Apis mellifera (38.42%) were the most abundant taxonomic groups. Some species (Ammophila sabulosa, Ectommius literates, Glypsus erubescens and Leptinotarsa decenlineata) were present in the department of Boundiali but absent in the ones of Kouto and Tingréla.
