%X Anomala denuda adults are not recognized as major crop pests. However, the presence of up to 46.508 individuals of the species was reported in one night in a maize field in Songon. The loss caused by their damage was estimated at 32% of the maize yield. Given the high incidence of damage by this beetle on maize production, we set ourselves the objective of carrying out experiments to control the A. denuda beetle using an aqueous extract of Ricinus communis (pesticidal plant). Such endeavor aims to reduce the attacks of this beetle and to improve maize production. This work was conducted on an experimental plot covering 2592 m2. Concentrations 110g/l (T1), 135.5g/l (T2), and 165g/l (T3) of the aqueous extract were applied with 6 replicates. Four applications were made per crop cycle in 2020 and 2021. The reference chemical insecticide used was Viper 46EC (16 Acetamiprid, 30 indoxacarb). Over the 2 crop cycles, all applied treatments were relatively effective compared to the control (p
