Abstract: The investigation was carried out to analyse the potency of bael leaf powder to control infestation of Rhizopertha dominica (F.). The four different concentrations (1gm to 4 gms) of bael leaf powder exhibited toxic effect against beetles at all the six intervals. Although the lowest dose (1gm) caused remarkable mortality (70% on 15th days after exposure). However percentage of mortality increased progressively. The absolute (100%) beetles death occurred on 15th day at 2 gms of concentration. The higher dose (3 gms and 4 gms) was more effective brought absolute morality at lower duration. The control showed only 10% and 30% mortality on 4th days and 10th days. The observation revealed the mortality rate varied according to the treatments and to the time of exposure. It can be used as insecticide against R. dominica.
