Abstract

The repellent activity of monoterpenoids viz. eugenol, zimtaldehyde and neem oil against
pulse beetle, Callosobruchus maculatus (F.) was investigated. Responses varied significantly with
compound, dose and exposure time. The tested components showed highest level of repellency
against C. maculatus at a dose of 1 μl. Over 80%, Class V, repellency was achieved after 5 to 60
min. treatment with the components at a dose of 1 μl. The repellent action of zimtaldehyde showed
the highest repellency (87.41% at 10 min exposure) status against C. maculatus than neem oil and
eugenol, while the lowest (79.46%) was recorded for eugenol at 25 min exposure level.

Key words: Repellency; eugenol; zimtaldehyde; neem oil; C. maculatus
