Rs Choudhary, Nk Bajpai And Ashok Kumar

The effect of low temperature on biological parameters of C. partellus was studied in the laboratory of Department of Entomology, Rajasthan College of Agriculture, Udaipur during Kharif 2011. Longest pupal period, 16.42 and 22.68 days, was observed at 3 0C under 5 and 10 days storage respectively. Adult emergence at 5, 10 and 15 days storage ranged from 12.0 to 69.0, 7.0 to 55.0 and 9.0 to 40.0 per cent respectively. Sex ratio, 0.68 to 0.43 were observed at 3 0C while females were increased comparatively to 0.94, 0.94 and 0.91 at 11 0C under 5, 10 and 15 days storage respectively. Number of eggs observed at 3, 5, 7, 9 and 11 0C under 5, 10 and 15 days ranged from 49.75 to 184.75, 31.5 to 168.75 and 39.75 to 151.50, respectively. Longest life span, 3.75, 3.25 and 3.0 days was recorded at 110C under 5, 10 and 15 days respectively.
