Food quality loss due to sorghum earhead bug Calocoris angustatus (Hemiptera: Miridae)



Food quality loss due to sorghum earhead bug Calocoris angustatus (Hemiptera: Miridae)



Journal of Plant Protection in the Tropics 10(1): 19-23



Studies on estimating losses in food quality of sorghum grains due to damage by different stages and densities of earhead bug Calocoris angustatus Lethierry were carried out. Fourth and fifth instar nymphs and both male and female adults changed the flour colour to pink. Similarly feeding by 40, 60 and 80 bugs per earhead resulted in pink coloured flour rendering it unattractive for consumption.
