The results revealed that the egg masses and adult population of C. gibbosa were first recorded during the 38th SMW and continued until crop harvesting in all cultivars and D 1 (First fortnight of May), and D 2 (First fortnight of June) sown crops, whereas it was observed during the 40 th SMW and 39 th SMW in the D 3 (Second fortnight of June) sown crop, respectively. Mean number of egg masses of C. gibbosa (0.15 egg Original Research Article
