ABSTRACT
Callosobruchus chinensis (L.) (Coleoptera Bruchidae) is one of the major insect pest infesting stored pulses in India. Recourse of synthetic insecticides to protect stored pulses often lead to dangers of the development of resistant strains, toxic residue and users safety. Locally available and less toxic pest management alternatives such as the use of effective botanicals are important. Essential oils of two variants of Cinnamomum verum Presl. Syn. C. zelanicum Blume from North East India (RRL J 1620 and RRL J 1622) were characterized and tested for their biological activity in vapour form against Callosobruchus chinensis (L.). Choice and no-choice tests showed that leaf and bark oil of two variants of C. verum Presl. had significant repellent action and reduced the fecundity and decreased egg hatchability of C. chinenisis (L.). However, leaf oil with higher percentage of eugenol exhibited better activity than the bark oil in both the tests. Hence, the volatile essential oils of both the variants of C. verum Presl. can be used safely as fumigants.
