Abstract: This study analyses the effects of land use in Hymenopterans diversity in Unguja Island, Zanzibar. Hymenopterans were sampled in five forms of land-use. In each study site, four linear transects of 50m long were established, three pan traps and sweep-nets were used to capture Hymenopterans. A total of 734 Hymenopterans consisting of 60 species were sampled. Kruskal Wallis test shows that species richness and diversity differ significantly among different land-use. There was no difference in efficiency between nets and pan traps in assessing Hymenopterans diversity (p > 0.1). Home gardens showed higher species richness than other study sites. There was no significance difference in Hymenopterans species richness and diversity captured by traps. This study concludes that home garden and mixed farming attract more Hymenopterans species than natural forest. The study recommends the conservations of Hymenopterans should be by establishment of home gardens and mixed crops farming practices.
