Biological activities of Allium sativum essential oil against pulse beetle, Callosobruchus chinensis (Coleoptera: Bruchidae)
Journal Title: Herba Polonica - Year 2014, Vol 60, Issue 2
Abstract
Essential oil from Allium sativum was isolated and investigated for its repellent, insecticidal, ovipositional and egg hatching inhibition activities against pulse beetle, Callosobruchus chinensis (Coleoptera: Bruchidae). A. sativum essential oil repelled bruchid adults at a very low concentration in choice oviposition assay. A. sativum essential oil caused both fumigant and contact toxicity in C. chinensis adults in a concentration dependent manner. Oviposition potency of C. chinensis adults was reduced significantly when sublethal concentrations of A. sativum essential oil were applied by fumigation and contact method. In chronic toxicity assay, A. sativum essential oil reduced F1 progeny emergence, damage and weight loss in seeds. Findings of the present study suggest that A. sativum essential oil can be useful as promising agent in insect pest management programme.
