Abstract
Human activities caused a several threat to the biodiversity in the
forest zone in Cameroon. Nevertheless, the situation in some ecoregion like dry
and humid savannah remains less study. Our study was conducted at Koutaba in
the West Region of Cameroon. Four land use system were selected in order to study
their influence on ant diversity, composition and distribution. Ant were sample
in a linear transect using pitfalls, baits and handling capture. Data was
analyses using species richness, Shannon and Pielou indexes for diversity and
Sorensen index for species composition. Venn diagram was used for species
richness distribution between land use system. Clam test and Individual value
were used to found relationship between ant species and land use system. A
total of 90 ant species belonged to 30 genera and six subfamilies were
collected. Myrmicinae was the richest subfamily with 10 genera and 44 species
collected. Palm grove with 63 species was rich and diverse (S=63; H’=2.69; J=
0.65) than other land use system. Ant composition was similar between palm
grove and savannah while orchard differ to all other land use system. Ant
community was numerically dominated by Myrmicaria opaciventris (53.31 %)
and Camponotus acvapimensis (11.08 %). Ant diversity and distribution
was influence by land use structure and human disturbance like mechanization of
agriculture in coffee farm and orchard and pasture activity in savannah.
