“…Even though H. hebetor is endemic to the region (Gahukar et al, 1986;Bhatnagar, 1987;Nwanze and Harris, 1992), it must either develop on an alternative host species or enter diapause in order to survive the period of MHM scarcity. Reproductive diapause can be induced in H. hebetor by a combination of photoperiod and low temperature (Chen et al, 2012) but there are no reports of H. hebetor diapausing naturally in the Sahel region and it is believed to develop throughout the year on a wide range of stored product moths, most commonly C. cephalonica in the cereal stocks of northern Burkina Faso (Waongo et al, 2013(Waongo et al, , 2015. In addition to stored-product moths, H. hebetor develops on several field pests, including Helicoverpa armigera (Hübner), Spodoptera spp., Earias spp.…”

“…Sorghum used in this experiment (purchased in a local market) was infested with four insect species including R. dominica, S. zeamais, T. castaneum and O. mercator . These species have been observed in traditional granaries in the Sudan ecological zone of Burkina Faso on sorghum (Waongo et al., 2013, 2015). Sitophilus sp have also been reported on stored maize in the same agroecology (Sudan ecological zone) (Baoua et al., 2016a).…”

“…Traditionally, sorghum is stored as panicles in straw or mud granaries (Waongo et al., 2013). In traditional storage conditions, in Burkina Faso, sorghum grains are attacked by several insect pests, with the lesser grain borer Rhyzopertha dominica (F.) (Coleoptera: Bostrychidae) being the most important (Waongo et al., 2015). Infestation of stored grains by R. dominica is known to cause losses in both quality (Williams et al., 1981) and quantity (Brower and Tilton, 1973).…”

“…L'analyse des paramètres mesurés permet de conclure une plus grande sensibilité du sorgho à grains rouges comparativement au sorgho à grains blancs. Le même constat avait été fait par Waongo et al (2015). Selon ces auteurs, la diversité des insectes ravageurs observés sur les grains de sorgho en milieu paysan était significativement supérieure à celle observée sur le sorgho à grains blancs et suggéraient donc une plus grande sensibilité du sorgho à grains rouge.…”

“…Les grains infestés par R. dominica sont alors vulnérables aux attaques des ravageurs secondaires et aux moisissures (Mukherjee et Nandi, 1993). Dans le contexte du Burkina Faso, les travaux de Waongo et al (2015) ont montré que R. dominica est une espèce pionnière (ravageur primaire) dans l'infestation des grains de sorgho stockés en milieu paysan. Par ailleurs, le sorgho est une source majeure d'énergie diététique et de protéines pour environ un milliard de personnes vivant dans les zones semi-arides (Belton et Taylor, 2004 ;Rooney, 2004 ;Songre-Ouattara et al, 2015) y compris le Burkina Faso (.…”
