摘要

Mango is a strategic crop in Côte d’Ivoire, but its production is severely constrained by fruit flies. This study evaluates eight control strategies against fruit flies in Northern Côte d’Ivoire (2023–2024). Results reveal a strong predominance of Bactrocera dorsalis (63.73%) and the significant emergence of Zeugodacus cucurbitae (24.52%) in mango orchards. While untreated plots recorded infestation levels exceeding 75%, Integrated Pest Management (IPM) combining attractants with either insecticides or biopesticides reduced these rates to below 5%. Notably, biopesticide-based control (spinosad) combined with attractants achieved high yields (9,887 kg/ha) and commercial quality (97.8%), performing comparably to conventional chemistry. These findings demonstrate that sustainable IPM strategies are technically viable for the mango sector and emphasize the need for urgent monitoring of Z. cucurbitae.
