Field experiment was conducted at the Zonal Agricultural Research Station, Vishweshwaraiah Canal Farm, Mandya during kharif 2018 and 2019, to assess the mechanism of resistance like earhead shape and colour of finger millet genotypes against earhead caterpillars viz., Cryptoblabes angustipennella (Hampson), Somena scintillans (Walker), Helicoverpa armigera (Hubner), Spodoptera frugiperda (J E Smith), Archips micaceana (Walker), Nola analis (Wileman and West), Cydia sp., Pyrausta phoenicealis (Walker), Corcyra cephalonica (Stainton) and Stathmopoda sp. Among the 230 genotypes screened against earhead caterpillars, droopy/lax and open earhead shape genotypes were completely free from the larval incidence. On the other hand, a large number of genotypes with purplish earheads showed a lower larval incidence (2.02 larvae/ earhead), indicating their higher level of resistance.
