Synergistic effect of juniper oil with phosphine gas on pulse beetle, Callosobruchus Chinensis L. (Coleoptera: Bruchidae)

Vaishali P Sawant, Shyamkant S Munje and Yugal K Yadu

In this study, the toxic effect of locally available volatile oil i.e. juniper oil in comparison with an organophosphorus insecticide / fumigant, phosphine gas was tested against pulse beetle, Callosobruchus chinensis L. The research work was carried out during September, 2017 to March, 2018 at the Regional Research Centre, Amravati (M.S.). Ninth homogenous susceptible generation of pulse beetle was taken as test insect. The effect of juniper oil doses (5, 10 and 15 per cent) and phosphine 4 ppm were studied alone and in combination against pulse beetle, C. chinensis L. Per cent mortality was observed at 20 minutes and 24 hours after exposure. It was observed that per cent mortality increased with increase in exposure period. Maximum mortality (100 per cent) was observed in the treatment, juniper oil 15 per cent + phosphine 4 ppm after 24 hours of exposure. While minimum mortality (13.33 per cent) was observed in the treatment, juniper oil 5 per cent after 20 minutes of exposure and it was 56.67 per cent after 24 hours of exposure to the treatment.
