Diversity of plants used to store cereals and leguminous and evaluation of the potential use of three aromatic plants against maize weevil Sitophilus zeamais (Coleoptera: Curculionidae)

Abstract

Study was conductedto inventory pesticidal plants used by smallholders to avoid attack of insect’s stored products at northern Cameroon. Then, to evaluate the effectiveness of three most reported against maize weevil. To this end, a survey was conducted and samples of plants were collected and identified. Granaries were setting up and a dose 1% w/w powder of each plant was mixed to maize. It was recorded that plants listed by producers belong to 16 families. Lippia rugosa (L) (Verbenaceae) reduces significantly the impact of S. zeamais on maize stored in granary compared to Hyptis spicigera (Lamiaceae) (X² = 1263.98, P
