Assessment of grain yield losses in pearl millet due to the millet stemborer, Coniesta ignefusalis (Hampson)



Assessment of grain yield losses in pearl millet due to the millet stemborer, Coniesta ignefusalis (Hampson)



Insect Science and its Application 23(3): 259-265



Studies were conducted at the ICRISAT Sahelian Centre, Niger, to assess damage and yield loss by the millet stemborer, C. ignefusalis on Pennisetum glaucum. Although 78% of stems were infested, late attack by the millet stemborer on millet plants resulted in bored stems yielding more than unbored ones. Artificial infestations with 5 and 10 larvae per plant at 2 weeks after plant emergence resulted in 50-70% plants with deadhearts and 24-100% avoidable yield loss.
