Abstract:
abitat transformations due to conversions of natural habitats to agricultural land are propelled by
increasing human populations and demand for resources. While such changes have enabled man
to optimally use available resources, they potentially undermine the capacity of ecosystems to
perform their functions. Ultimately, it is the inhabitant populations and species of flora and fauna
that suffer. However, little information and knowledge of insect species populations and
composition makes reliable recommendation difficult. Our study surveyed insect species in two
areas; agricultural and virgin landscapes using pitfall traps and revealed that the virgin landscapes
had richer biodiversity. The composition of functional groups in the virgin landscape was also
more balanced than that of the agricultural landscape showing better population regulation
mechanisms. The findings reveal the linkages that exist between habitat characteristics and species
composition as well as functional groups and population regulation.
