Survival of Calocoris angustatus (Hemiptera: Miridae) nymphs on diverse sorghum genotypes



Survival of Calocoris angustatus (Hemiptera: Miridae) nymphs on diverse sorghum genotypes



Journal of Economic Entomology 86(2): 607-613



Studies were conducted on insect survival and grain damage, percentage loss in grain weight, and seed germination of nine sorghum cultivars across three infestation levels (100, 250 and 500 nymphs per panicle) of Calocoris angustatus Lethiery over 4 growing seasons during 1984-1986. 'IS 2761', 'IS 17645', and 'IS 9692' showed evidence for low nymphal survival. 'IS 17610', 'IS 17645', and 'IS 9692' suffered low grain damage, whereas 'CSH 5', 'IS 9692', 'IS 17610', 'IS 17618', 'IS 17645', and 'CSH 1' showed tolerance to bug feeding in decreasing order of consistency. 'IS 17610', 'IS 17618', and 'IS 17645' showed significantly (P < 0.05) better seed germination than the susceptible controls 'CSH 1', 'CSH 5', and 'CSH 9'. Nymphal survival, tolerance, and seed germination decreased, and grain damage increased, with an increase in insect density.
