This branch describes the verdicts of field studies conducted in Kordofan State (Sudan) having to do with ecological limits of the millet head miner, Heliocheilus albipunctella (DE JOANNIS, 1925), which is a main pest on gem millet, (Pennisetum glaucum (L.) R. BR). The results documented that in the on-station, El-Obeid region, the moths appeared engaged earlier in August, that is, on 14/8/93, while at Abu Zabad location came into view on 23/8/93. The moths disappeared earlier in September, that is, on 18/9/93 in the first location and on 23/8/93 and 4/10/93, individually in the second location.The rise of moths of H. albipunctella from diapausing pupae in the laboratory happen in August, i.e. all the while the period from 26/8–1/9. No moths arose in the laboratory after that ending. The findings told that compact heads supported considerably fewer tunnels (P < 0.01), distinguished to loose almost compact heads. In conclusion, the appearance of the millet-wiggle, Heliocheilus during the moist season coincided with the course stage of the millet and its vanishing from the field with the adulthood of the crop. The oviposition sites recorded were the heads of millet only, no different oviposition site, and/or added plant parts were recorded.
