Abstract

Studies on the biology of C.serratus at ambient conditions, RH 50%, 80% and 90% at temperature 30oC revealed the average egg period as 6.3, 10.42, 5.48 and 7.12 days, the grub period of 21.08, 23.08, 20.72 and 19.18 days and the pupal period of 9.22, 13.66, 9.4 and 9.66 days at ambient conditions, RH 50%, 80% and 90% at temperature 30 oC, respectively. The average longevity of adult male was 12.78, 20.98, 14.58 and 13.18days and adult female was 17.94, 25.44, 17.34 and 15.52 days at above ambient conditions.
