Abstract:Field plots of corn, pearl millet, and sorghum were hand infested with egg masses of Diatraea grandiosella (Dyar) to study the effects of infestation time and planting date. Host plants reacted similarly, but corn had the greatest amount of damage, millet had the least, and sorghum had an intermediate amount. Plants infested 2 weeks after anthesis had the least stalk tunnelling, but the earliest infestation time had fewer ears of corn tunnelled. Late plantings of corn and male fertile sorghum had more damage than earlier plantings. The intermediate planting of millet had the least tunnelling. Late-planted corn yielded the least. Conversely, millet and sorghum had heavier losses when planted earlier. Male sterile sorghum (no pollen) had a higher percentage of tunnelled plants and slightly longer tunnels, but fewer heads tunnelled when compared with male fertile sorghum.
