Abstract
- This study on the comparative biology Pectinophora gossypiella (Saunders) was carried out at the University of Agricultural Sciences, Raichur, Karnataka, in insect rearing growth chamber (25± 1°C, 65± 5% RH and photoperiod of 14:10 hr, L: D) during 2018-19. The results revealed that the incubation period was 3.5± 0.82 and 3.05± 0.55 days in non-diapausing and diapausing populations, respectively; a total larval period of 18.60± 2.28 and 19.65± 1.53 days, respectively was observed without any significant difference; and adult longevity of male and female was 9.05± 0.55 and 9.55± 0.83 days, respectively in non-diapausing population, while in diapausimg population it was 9.75± 0.26 and 10.25± 0.43 days. Total life cycle of non- diapausing population was significantly shorter (42.85± 4.99 days) as compared to diapausing one (134.3± 12.91days) with fecundity of 112.34± 10.31 and 104.54± 9.96 eggs, respectively. The longer lifecycle of diapausing population was due to long resting diapausing period ranging from 72 to 108 days. [ABSTRACT FROM AUTHOR]
