Abstract
Pearl millet, Pennisetum glaucum (L.) R. Br., is a crop grown throughout West Africa, especially in the Sahel. Pearl millet is the major staple food for the population of the Sahel, particularly for household use. It is one of the world’s most resilient drought-tolerant cereal crops, surviving even in the poorest soils in the driest regions and in the hottest climates. Despite this extreme climatic adaptation, pearl millet suffers from many biotic constraints, including insect pests (Nwanze and Harris, 1992). Among these, the stem borer (MSB) Coniesta ignefusalis (Hampson) (Lepidoptera: Crambidae) and the millet head miner (MHM) Heliocheilus albipunctella (de Joannis) (Lepidoptera: Noctuidae) are the major chronic insect pests of millet in the Sahel, including Niger. The MSB develops on many species of the Poaceae family; in the Sahel, it develops 2–3 generations per year on pearl millet during the rainy season and diapauses in leftover pearl millet stems during the rest of the year (Youm et al., 1996). The damage from C. ignefusalis is due to the feeding of developing larvae in millet stalks; first generation larvae cause dead hearts and stand loss, while the second and third generations cause lodging, disruption of the vascular system, and inhibition of grain formation (Harris, 1962; Youm et al., 1996). The MHM is a univoltine and monophagous species, which develops on millet in the Sahel during the rainy season between July and October and spends the remainder of the season in diapause in the soil (Gahukar et al., 1986). Infestations of H. albipunctella are more severe in the drier zones of the Sahel (Nwanze and Harris, 1992). The damage from H. albipunctella is due to larvae that feed on the panicle and prevent grain formation (Nwanze and Harris, 1992). Almost every year, outbreaks of the MHM are observed in the Sahel, especially on millet planted early or earlymaturing cultivars, while millet planted later or late-maturing cultivars is more affected by MSB (Gahukar et al., 1986; Youm et al., 1996). Both insect pests inflict significant yield losses ranging from 15% to total crop failure for C. ignefusalis (Harris, 1962; Ajayi, 1990) and from 40% to 85% for H. albipunctella (Gahukar et al., 1986; Krall et al., 1995)...
