Host plant resistance (HPR), as a component of integrated pest management, has been employed for few of the many insects recorded as pests of the panicles of sorghum {Sorghum bicolor (L.) Moench] and even fewer for pearl millet [Pennisetum glaucum (L.) R.B]. This paper reviews global HPR breeding programs for sorghum midge [Stenodiplosis sorghicola (Coquillett)], earhead bug [Calocoris angustatus Lethierry), ,African sorghum head bug.[Eurystylus oldi (Poppius)], corn earnow[Helicoverpa armigera (Hübner) and Helicoverpa zea (Boddie)]. and millet head miner [He liocheilus albipunctella (de Joannis)]. Major progress has been made in combining enhanced levels of HPR to sorghum midge with local adaptation in the breeding programs at ICRISAT Asia Center and Texas A&M University and in Austratia. On-farm adoption of this developed technology has occurred rapidly and at a high level in Australia. Breeding for HPR to other insects has attracted less effort. HPR research for earhead bugs in lndia and African sorghum head bugs in West Africa has progressed to the point that cultivars with resistance to these pests soon will be available to farmers. The open panicle type is routinely selected in breeding programs in regions where corn earworm is a pest. Breeding programs for HPR to millet head miner need further development.

Digestibility by dairy cows of monosaccharide components in diets containing either ground sorghum or sorghum grain treated with sodium hydroxide.
1997
Miron J. | Ben Ghedalia D. | Solomon R.
Five cows in midlactation and equipped with ruminal and abomasal canulas were fed two isonitrogenous diets composed of 46% sorghum grain, either ground or treated with 4% NaOH, plus 39% wheat silage and 15% supplements. The DMI were 16.3 and 15.8 kg/d for cows fed the diets containing ground sorghum and treated sorghum, respectively. The digestibility of NDF polysaccharides was higher for cows fed the treated sorghum, but the digestibility of neutral detergent soluble alpha-glucans (starch) was higher for cows fed ground sorghum. Digestibility of total carbohydrate was 79% for cows fed the diet containing ground sorghum and 67% for cows fed the diet containing sorghum treated with NaOH. Ruminal pH was higher in cows fed the diet with treated sorghum, but total ruminal VFA concentration was higher in cows fed the diet containing ground sorghum. Profiles of individual ruminal VFA and NH3 concentration were similar for both treatments. Flow of NAN through the abomasum of cows fed ground sorghum was higher than that of cows fed the sorghum treated with NaOH, and N absorption in the intestine followed a similar trend. The data indicated a possible advantage for dairy cows fed ground sorghum than for those fed grain treated with NaOH.
