Subject Sorghum
 
Description Sorghum is an important cereal crop in Asia, Africa, Americas and Australia. Grain
yields on farmers’ fi elds in Asia and Africa are generally low (500−800 kg ha-1) mainly
due to insect pest damage. Nearly 150 insect species have been reported as pests
on sorghum (Sharma 1993), of which sorghum shoot fl y (Atherigona soccata), stem
borers (Chilo partellus, Busseola fusca, Eldana saccharina and Diatraea spp.),
armyworms (Mythimna separata, Spodoptera frugiperda and S. exempta), shoot
bug (Peregrinus maidis), aphids (Schizaphis graminum and Melanaphis sacchari),
spider mites (Oligonychus spp.), grasshoppers and locusts (Hieroglyphus, Oedaleus,
Aliopus, Schistocerca, and Locusta), sorghum midge (Stenodiplosis sorghicola),
mirid head bugs (Calocoris angustatus and Eurystylus oldi), and head caterpillars
(Helicoverpa, Eublemma, Cryptoblabes, Pyroderces, and Nola) are the major pests
worldwide. Other insects reported to be damaging sorghum are of regional/local
importance. Annual losses due to insect pests differ in magnitude on a regional
basis. They have been estimated to be $1,089 million in the semi-arid tropics (SAT),
$250 million in United States, and $80 million in Australia (ICRISAT 1992). In India,
nearly 32% of sorghum crop is lost due to insect pests (Borad and Mittal 1983).
