However, its importance the production system Cameroon has not been investigated. The study assesses farmers' perception on of Z. systems humid forest zone Southern Cameroon. Research was carried out 5 villages each three Agro-Ecological, Cultural Demographic Blocks (AECD-Blocks) Forest Margin Benchmark Area (FMBA). In village, a semi-structured survey used; male female groups farmers were interviewed separately. present throughout Cameroon, where it ranked third most economically important insect agriculture. opinion, polyphagous with little impact young perennial crops. length pre-farming fallow does affect pressure following increased grasshopper observed today fields, compared to what existed 10 years ago result deforestation increase surface herbaceous fallow. damage caused by higher fields adjacent C. odorata fallows than those forests shrubby fallows. fight against this often done through physical methods hand, for human consumption. highlight low usage chemical total absence biological ecological methods.
