Assessment of 10 years of maize pedigree breeding for European corn borer tolerance and high-yielding combining ability Inra
Panouillé, A.; Anglade, P.; Boyat, A.; Gouesnard, B.; Vible, J.C.; Dupin, B..
Pour associer la tolérance à la pyrale (O. nubilalis Hbn.) aux caractères agronomiques habituellement sélectionnés, des programmes de création et d’évaluation de lignées du maïs ont été développés par les laboratoires Inra du Maïs (Montpellier, Saint-Martin de Hinx, Bordeaux). En pépinière et dans les essais d’évaluation, la tolérance est exprimée par une note de dégâts à maturité corrigée pour les différences de précocité du matériel. L’utilisation de lignées étalons éprouvées et reconnues stables permet le classement de lignées en trois groupes de tolérance. La méthode de sélection généalogique repose sur une sélection simultanée par niveaux indépendants pour les deux caractères. Des essais de valeur hybride sur différents testeurs complètent les tris en...

Differences in oviposition behaviour of two sympatric sibling species of the Ostrinia genus Inra
Malausa, T.; Pélissié, B.; Piveteau, V.; Bourguet, D.; Ponsard, S..
Changes in host preferences are thought to be a major source of genetic divergence between phytophagous insect taxa. In western Europe, two sympatric taxa, O. nubilalis (the European corn borer) and O. scapulalis, feed mainly on maize and hop or mugwort, respectively. These two species may have diverged without geographic isolation after a host shift of ancestral populations onto maize or another cultivated species (e.g. sorghum). A previous study using inbred laboratory strains revealed that the two species differ in their oviposition choices in maize-mugwort tests. We sampled four natural populations in France (two of each taxon) and tested their oviposition behaviour toward four of their main host plant species: maize, sorghum, mugwort and hop. O....

Genetic structure and gene flow in French populations of two Ostrinia taxa: host races or sibling species? Inra
Malausa, T.; Dalecky, A.; Ponsard, S.; Audiot, P.; Streiff, R.; Chaval, Y.; Bourguet, D..
Most models of ecological speciation concern phytophagous insects in which speciation is thought to be driven by host shifts and subsequent adaptations of populations. Despite the ever-increasing number of studies, the current evolutionary status of most models remains incompletely resolved, as estimates of gene flow between taxa remain extremely rare. We studied the population genetics of two taxa of the Ostrinia genus — one feeding mainly on maize and the other on mugwort and hop — occurring in sympatry throughout France. The actual level of divergence of these taxa was unknown because the genetic structure of populations had been investigated over a limited geographical area and the magnitude of gene flow between populations had not been estimated. We...

Two multiple sets of eight and five microsatellite markers for the European corn borer, Ostrinia nubilalis Hübner (Lepidoptera: Crambidae) Inra
Dalecky, A.; Bogdanowicz, M.; Dopman, E.B.; Bourguet, D.; Harrison, R.G..
Primer sequence and polymorphism data are presented for 13 microsatellite loci isolated from the European corn borer moth, Ostrinia nubilalis, as part of a project to construct a linkage map for the two pheromone strains. Experimental conditions are described for polymerase chain reaction (PCR) multiplexing, which allows genotyping in two electrophoresis runs of eight and five markers each. In a sample of 27 individuals coming from one European locality, the number of alleles per locus ranged from one to 12, and gene diversity from 0 to 0.859. Seven loci showed a deficit of heterozygotes. Eleven loci cross-amplify in the related Ostrinia furnacalis
