abstract: The ecobiology of pink bollworm, Pectinophora gossypiella (Saunders) infesting cotton (cv. NHH 44) was studied at fluctuating ambient temperatures and also on artificial diet. No significant differences were observed in life-cycle. However, the influence of declining temperature was evident in extending the life-cycle period. This was supplemented with an increse in the duration of life-cycle, vit, 38.95,42.01 and 42.68 days during Oct-Nov, Nov-Dec and Dec-Jan, respectively. The lawa passed through 5 stadia and showed geometric increase in the width of the head capsule at each moult. The moths fed with honey produced an average of 129 eggs as compared to 20.6 eggs when raised on water alone. There was a significant increase in the pupal weight when reared on artificial diet than on cotton bolls for two consequent generations. Sex ratio of the moths reared on artificial diet was in consonance (60.3:29.7 and 53.3:46.7) with those reared on cotton bolls (50.8:49.2). The artificial diet proved to be suitable in rearing pink bollworm across two generations without affecting its fecundity. Among the different foods offered, significantly higher adult longevity was recorded on honey, followed by sugar syrup, fresh cotton flowers, water alone, and without food and water
