Description The reaction of 15 sorghum genotypes to A. soccata was evaluated in terms of antixenosis for oviposition, antibiosis, and recovery resistance under greenhouse and field conditions in Patancheru, Andhra Pradesh, India, during 2004 and 2005 to identify genotypes with stable resistance to the insect. Antixenosis for oviposition was observed under multi- and dual-choice conditions in IS 1054, IS 1057, IS 2146, IS 4664, IS 2312, IS 2205, SFCR 125, SFCR 151, ICSV 700 and IS 18551. However, antixenosis for oviposition was not apparent under no-choice conditions. Antibiosis (expressed in terms of prolonged larval and pupal development, and/or larval and pupal mortality) was observed in IS 2146, IS 4664, IS 2312, SFRC 125, ICSV 700 and IS 18551. IS 1054, IS 1057, IS 2146, IS 2205 and IS 4664 showed lower percentages of tiller deadhearts than the susceptible control, Swarna. IS 2312, SFCR 125, SFCR 151, ICSV 700 and IS 18551, which exhibited antixenosis, antibiosis and tolerance components of resistance, may be used in sorghum improvement programmes to develop sorghum cultivars with resistance to this pest. Genotypes with diverse combination of characteristics associated with resistance to sorghum shoot fly can be used in breeding programmes to broaden the genetic base and increase the levels of resistance to this pest.
