Description Various techniques to increase infestation and improve efficiency of screening sorghum for resistance to Contarinia sorghicola were tested in Andhra Pradesh, India, in 1980. Adjustment of planting date to synchronize flowering with the period of peak abundance of adults, planting infested rows of susceptible cultivars 20 days before the test cultivars, spreading damaged sorghum panicles containing diapausing larvae in infested rows and using sprinkler irrigation during flowering in the post-rainy season, helped to increase abundance. Careful and selective use of contact insecticides to control the mirid Calocoris angustatus and the eulophid Tetrastichus diplosidis [Aprostocetus diplosidis] were useful in screening and selecting sorghum cultivars for resistance. Planting 2 sets of test material at 14 day intervals reduced the chances that the sorghum would escape damage. Maintaining thin plant stands also increased damage by preventing population dilution due to fewer numbers of panicles per unit area.
