Bioactivity of cineole against rice weevil (Sitophilus Oryzae L.) on stored wheat

These investigations aimed to determine bioactivity of cineole essential oil against rice weevil (Sitophilus oryzae L.) on stored wheat. Therefore, three different experiments with cineole were carried out: first, to test efficacy of cineole against different developmental stages of rice weevil in wheat grain ; second, to test effective concentration of cineole against rice weevil in space 50% filled up with wheat applying cineole in the concentration range of 50, 100, 150, 200, 250 g m-3 ; and third, to test effective concentration of cineole in spaces differently filled up with wheat (empty space, 50% and 95% filled up). Though cineole exhibited certain fumigant characteristics it would be needed to apply high concentrations (doses) relative to phosphine or methyl bromide to gain satisfactory results. If the problem of cost- effective commercial production can be solved, cineole could find a place in IPM strategies, especially where the emphasis is on environmental and food safety and on replacing the more dangerous and toxic fumigants and insecticides.
