The population genetics and phylogeography of African phytophagous insects have received little attention. Some, such as the maize stalk borer Busseola fusca, display significant geographic differences in ecological preferences that may be congruent with patterns of molecular variation. To test this, we collected 307 individuals of this species from maize and cultivated sorghum at 52 localities in West, Central and East Africa during the growing season. For all collected individuals, we sequenced a fragment of the mitochondrial cytochrome b. We tested hypotheses concerning the history and demographic structure of this species. Phylogenetic analyses and nested clade phylogeographic analyses (NCPA) separated the populations into three mitochondrial clades, one from West Africa, and two--Kenya I and Kenya II--from East and Central Africa. The similar nucleotide divergence between clades and nucleotide diversity within clades suggest that they became isolated at about the same time in three different refuges in sub-Saharan Africa and have similar demographic histories. The results of mismatch distribution analyses were consistent with the demographic expansion of these clades. Analysis of molecular variance (amova) indicated a high level of geographic differentiation at different hierarchical levels. NCPA suggested that the observed distribution of haplotypes at several hierarchical levels within the three major clades is best accounted for by restricted gene flow with isolation by distance. The domestication of sorghum and the introduction of maize in Africa had no visible effect on the geographic patterns observed in the B. fusca mitochondrial genome.

Abstract. Busseola fusca (Fuller) (Lepidoptera: Noctuidae) is one of the major cereal pests in subSaharan Africa. Previous phylogeographic investigations on samples collected in Kenya, Cameroon and West-Africa showed the presence of three main clades (W, KI, KII) originated from populations isolated in West and East Africa around one million years ago. Demographic and phylogenetic analyses suggested that this event was followed by local demographic expansion and isolation by distance. These hypotheses were tested by a more comprehensive sampling across B. fusca's geographic range in Africa. Comparisons of sequences of partial mitochondrial DNA gene (cytochrome b) from 489 individuals of 98 localities in southern, central, eastern and western African countries confi rmed the presence of the three main clades. Phylogenetic, F-statistics, demographic parameters and nested clade phylogeographic analyses confi rmed that the clades experienced geographic and demographic expansion with isolation by distance after their isolation in three refuge areas. The geographic range of clade KII, already known from East to Central sub-Saharan Africa was extended to Southern Africa. Mismatch distribution analysis and the negative values of Tajima's D index are consistent with a demographic expansion hypothesis for these three clades. Signifi cant genetic differentiations were revealed at various hierarchical levels by analysis of molecular variance (AMOVA). Hypotheses about the geographic origin of the three main clades are detailed. Résumé. Scénario phylogéographique et histoire évolutive régionale du foreur de graminéesBusseola fusca (Fuller) (Lepidoptera : Noctuidae) en Afrique sub-saharienne. Busseola fusca (Fuller) (Lépidoptère : Noctuidae) est l'un des ravageurs majeurs des cultures céréalières en Afrique Subsaharienne. Une première étude phylogéographique portant sur des individus échantillonnés au Kenya, au Cameroun et en Afrique de l'Ouest a montré l'existence de trois clades principaux (W, KI, KII) issus de populations isolées à l'Ouest et à l'Est de l'Afrique il y a environ un million d'années. Les analyses démographiques et phylogénétiques indiquent que cet événement a été suivi d'une expansion démographique locale avec des phénomènes d'isolement par la distance. Ces hypothèses ont été testées à plus grande échelle grâce à un échantillonnage des populations de B. fusca couvrant désormais la majeure partie de son aire de distribution. Le séquençage d'un fragment du gène mitochondrial codant pour le cytochrome b chez 489 individus provenant de 98 localités des pays sud, centre, est et ouest africains confi rme l'existence des trois clades observés précédemment. Les résultats des analyses phylogénétiques, les paramètres démographiques, les statistiques de Wright ainsi que les analyses des clades emboîtés confi rment que ces trois populations, après avoir été isolées dans des aires refuges différentes, ont connu une expansion démographique et géographique avec un isolement par la distance.

“…Alternative hosts in the vicinity of the crop fi elds and crop residues enhance survival of borers during off -season, and thereby are responsible for pest attacks on crops in the subsequent season (Polaszek & Khan 1998). In contrast, oviposition preference studies showed certain wild grasses to be highly attractive to ovipositing moths, though larval survival and adult fecundity are generally low (Haile & Hofsvang 2002). Based on these interactions, hypotheses has been created and validated with fi eld and laboratory trials for S. calamistis and E. Saccharina (Shanower et al 1993;Schulthess et al 1997).…”

Abstract. Presence of wild host plants of stem borers in cereal-growing areas has been considered as reservoirs of lepidopteran stem borers, responsible for attack of crops during the growing season. Surveys to catalogue hosts and borers as well as to assess the abundance of the hosts were carried out during the cropping and non-cropping seasons in different agro-ecological zones along varying altitude gradient in Kenya. A total of 61 stem borer species belonging to families Noctuidae (25), Crambidae (14), Pyralidae (9), Tortricidae (11) and Cossidae (2) were recovered from 42 wild plant species. Two noctuids, Busseola fusca (Fuller), Sesamia calamistis Hampson, and two crambids, Chilo partellus (Swinhoe) and Chilo orichalcociliellus (Strand) were the four main borer species found associated with maize plants. In the wild, B. fusca was recovered from a limited number of host plant species and among them were Sorghum arundinaceum (Desvaux) Stapf, Setaria megaphylla (Steudel) T. Durand & Schinz, Arundo donax L. and Pennisetum purpureum Schumacher. In contrast, the host range of C. partellus was considerably wider [13 for S. calamistis]. However, the number of larvae of these species was lower in the wild compared to cultivated fi elds, thus the role of natural habitat as a reservoir for cereal stem borers requires further studies. Importance of the wild host plants as well as borer diversity along the altitudinal gradient is discussed.Résumé. Le rôle des plantes hôtes sauvages dans l'abondance des lépidoptères foreurs de graminées selon un gradient altitudinal au Kenya. La présence de plantes hôtes sauvages de foreurs autour des parcelles cultivées a toujours été considérée comme préjudiciable à la production des céréales dans la mesure où elles constituent des réservoirs pour les foreurs. Des enquêtes ont été menées au Kenya, pendant et en dehors des périodes culturales, selon un gradient altitudinal, afi n de déterminer le rôle de ces plantes hôtes sur les populations de ravageurs. Soixante et une espèces de lépidoptères foreurs appartenant aux familles des Noctuidae (25), Crambidae (14), Pyralidae (9), Tortricidae (11) et Cossidae (2) ont été récoltées sur 42 plantes hôtes sauvages. Les principales espèces de foreurs associées au maïs sont Busseola fusca (Fuller) et Sesamia calamistis Hampson (Noctuidae) et Chilo partellus (Swinhoe) et Chilo orichalcociliellus (Strand) (Crambidae). Dans les habitats sauvages, B. fusca a été trouvé sur un nombre restreint de plantes hôtes sauvages telles que Sorghum arundinaceum (Desvaux) Stapf, Setaria megaphylla (Steudel) T. Durand & Schinz, Arundo donax L. and Pennisetum purpureum Schumacher. A l`inverse, S. calamistis et C. partellus ont été trouvées associées à plus de plantes hôtes sauvages [S. calamistis (13), C. partellus (5)]. Toutefois, le nombre total de chenilles de ces quatre espèces de ravageur trouvé dans les habitats sauvages est très inférieur à celui trouvé dans les parcelles cultivées, aussi le rôle des habitats sauvages en tant que réservoir pour les lépidopt...
