Description Observationson oviposition on sorghum plants by Atherigona Goccata Rand, at ICRISAT Center, near Hyderabad, India, confirmed its high rate of incidence particularly during postrainy season. Eggs were normally laid on the under
surface of the fourth or fifth leaf, usually one egg per plant was laid. The number of eggs laid was highest per unit area at high plant densities--10 mm or less between plants. At these densities more plants were laid on, and
this applied to both main plants and tillers. There was a very high correlation between the number of plants laid on and the number showing dead heart symptoms. Very few plants at low densities escaped attack. Soil type did not
affect oviposition. It was concluded that, for maximizing shoot fly build-up for screening for resistance in sorghum, dense plant populations should be sown in the spreader rows, but for material under test spacings of 200 mm or
more were optimal
