Description Four mirid head bugs, Calocoris angustatus Leth., Creontiades pallidus Ramb., Eurystylus bellevoyei Put. and Reut., and Campylomma sp., infest sorghum at ICRISAT Centre in India. C. angustatus is the predominant species, followed by Campylomma sp., C. pallidus and E. bellevoyei. The incidence of C. angustatus is higher in crops grown on Vertisols than on Alfisols, and maximum numbers are recorded in panicles at the milk stage. Females of C. angustatus lay eggs inside the glumes before anthesis, whereas the other species insert their eggs in the grain at the milk stage. The life cycle is completed in 15–20, 17–23, 14–16 and 16–17 days by C. angustatus, C. pallidus, E. bellevoyei, and Campylomma sp., respectively. The maximum numbers of C. angustatus, C. pallidus and E. bellevoyei were recorded during September–October, whereas Campylomma sp. tended to be most active during March–June.
