ABSTRACT
The effect of plant oil treatments extracted from Khaya ivorensis and Azadirachta indica was evaluated on adult maize weevils Sitophilus zeamais reared grain. Four replicates each treatment oils were constituted at 0% (control untreated), 1 ml, 2 3 ml doses. Each the pytochemical synthetic chemical (Daksh- Dichlorvos 100% EC w/v) introduced into experimental jars (300 cm3) graded levels, before 20 g clean grain incorporated. separated grains with perforated white paper, 10 newly emerged S. added to including control (untreated) experiment, which contain but no added. for their toxic zeamais, oviposition, F1 progeny emergence, damage weight loss. Data collected analyzed using ANOVA. means LSD P>0.05.The results revealed that when compared experiment. Among plants, essential K. significantly (P>0.05) suppressed egg laying, emergence damage. Therefore, A. is useful in zeamais.
