Abstract
Ziziphus tree species offer valuable socio-economic and ecological benefits but experience significant damage from insect pests. In Ethiopia, there is limited knowledge on the insects attacking Ziziphus fruits and a study aimed to identify these pests, assess their impact and understand how different land use types (LUTs), affect them were conducted. Sampling involved collecting fifty fruits and ten leaves from ten randomly chosen Ziziphus trees per LUT within each agroecological zone from August to December in 2022 and 2023. Samples were visually assessed for incidence and infestation levels, and the five morphotypes were identified using molecular techniques through phylogenetic analysis. Fruit pest incidence varied during the season yet a positive correlation (r = 0.84) was observed among the assessment months and years. Most fruits showed low to medium infestation levels (5–50%), while severe infestations (>75%) were predominant in the lowland agroecological zone. The insects attributed to the damage were identified as Carpomya incompleta (Becker), Drosophila hydei Sturtevant, D. simulans Sturtevant and Zaprionus indianus Gupta. Fruits showed higher incidence and infestation levels than leaves, indicating significant yield and income losses. Thus, implementing effective management strategies is vital to minimize these losses and achieve sustainable production in Ethiopia.
