Seasonal occurrence of sorghum earhead bug, Calocoris angustatus Lethierry (Hemiptera: Miridae) in southern India



Seasonal occurrence of sorghum earhead bug, Calocoris angustatus Lethierry (Hemiptera: Miridae) in southern India



Tropical Pest Management 351: 70-77



The seasonal occurrence of Calocoris angustatus in the main and ratoon crops of 2 sorghum hybrids was studied in field experiments in Tamil Nadu, India, with fortnightly sowings. During April-June 1984, April sowings were severely infested while early June sowings had lower infestation. Hybrid CSH 5 harboured more bugs than K-Tall. A ratoon crop had a lower population than the main crop.
