Vertical distribution of S tomoxys spp. ( D iptera: M uscidae) in a rainforest area of G abon

Stomoxys flies exhibit distinct vertical distribution patterns in Gabon's Ivindo National Park, with near-ground levels (50 cm) hosting higher densities of species like S. calcitrans and S. transvittatus, while S. xanthomelas thrives in the canopy (20–30 m). This vertical stratification correlates with feeding behavior, as blood meal analysis revealed heterogeneity among hosts. The study, conducted using Vavoua traps at four forest layers over 15 days per month from April to June 2006, found significant differences in fly abundance across both vertical strata (H = 36.91; P < 0.001) and species (H = 41.11; P < 0.001). Notably, S. inornatus was most abundant at 10 m, underscoring the flies' ubiquity across rainforest layers. These findings highlight the need for comprehensive vector control strategies in this ecologically and touristically significant area.
