Abdullah Ahmady, Magdi AA Mousa, Ahmed A Zaitoun

The stored pulse grain experiences major threat from insect pests. Callosobruchus maculatus is one of the major pests infesting stored pulses worldwide. In this study the insecticidal activity of eight botanical oils, Citronella, Clove, Eucalyptus, Jojoba, Lemon, Orange, Rosemary, Spearmint were tested against the adults of C. maculatus in the laboratory. The results of this study showed that all used oils have potential of protection to control storage product pests, C. maculatus. The highest mortality was observed on clove and jojoba followed by rosemary eucalyptus and citronella. The mortality was increased with increase of concentration levels and the duration dependent increased percent mortality was observed in all botanical oils after interval of different exposure time. The present study suggested that botanical oils (Clove, Jojoba, Rosemary and Eucalyptus) exhibited a possibility to be an alternative to the synthetic insecticides in the management of stored product pests, especially C. maculatus.
