Differences in resistance to stored grain insects as a result of natural selection have been recognized in maize. In newly developed germplasm and hybrids, this natural resistance has to be conserved or increased. Selection for resistance to several species of field-to-storage or stored-product insects has been attempted. Screening techniques to detect and evaluate resistance are described in detail for the grain weevils, red flour beetle, lesser grain borer, larger grain borer, khapra beetle, Angoumois grain moth, and Indian meal moth. Precautions at harvest to preserve the integrity of the grain, methods of conditioning the grain and measuring and adjusting its moisture content before testing, and x-ray inspection are considered.
