Seasonal incidence and abundance of Campoletis chlorideae Uchida in relation to the activity of Helicoverpa armigera Hubner in sorghum



Seasonal incidence and abundance of Campoletis chlorideae Uchida in relation to the activity of Helicoverpa armigera Hubner in sorghum



Karnataka Journal of Agricultural Sciences 17(4): 819-820



A study was undertaken in Dharwad, Karnataka, India, to gather information on the effect of sorghum (Sorghum bicolor) sowing date (15 May (early), 8 June (normal) and 20 June (late)) on the incidence of H. armigera and parasitoid C. chlorideae. The incidence of H. armigera was observed from flowering until crop maturity. The maximum incidence (larvae per earhead) of 6.85 was observed in the early sowing.
