Geographic and voltinism differentiation among North American Ostrinia nubilalis (European corn borer) mitochondrial cytochrome c oxidase haplotypes
DNA sequence of European corn borer, Ostrinia nubilalis (Hubner) (Lepidoptera: Crambidae), mitochondrial cytochrome c oxidase I (cox1) and II (cox2) genes were characterized and used for population genetic analysis. Twenty-six point mutations were identified from a 2,156 bp DNA sequence alignment. The frequency of polymorphic cox1DdeI and HaeIII, and cox2 Sau3AI and MspI restriction sites were ...
متن کاملMolecular differentiation at nuclear loci in French host races of the European corn borer (Ostrinia nubilalis).
French populations of the European corn borer consist of two sympatric and genetically differentiated host races. As such, they are well suited to study processes that could be involved in sympatric speciation, but the initial conditions of host-race divergence need to be elucidated. Gene genealogies can provide insight into the processes involved in speciation. We used DNA sequences of four nu...
متن کاملLinking larval nutrition to adult reproductive traits in the European corn borer Ostrinia nubilalis
Throughout an organism’s lifetime, resources are strategically allocated to many different functions, including reproduction. Reproduction can be costly for both sexes; females produce nutrient-rich eggs, whereas males of many species produce large and complex ejaculates. In capital breeding insects, nutrients are mainly acquired during the larval period, yet allocation decisions impact the rep...
متن کاملEuropean Corn Borer (Ostrinia nubilalis) Induced Responses Enhance Susceptibility in Maize
Herbivore-induced plant responses have been widely described following attack on leaves; however, less attention has been paid to analogous local processes that occur in stems. Early studies of maize (Zea mays) responses to stem boring by European corn borer (ECB, Ostrinianubilalis) larvae revealed the presence of inducible acidic diterpenoid phytoalexins, termed kauralexins, and increases in t...
متن کاملInsights into genome differentiation: pheromone-binding protein variation and population history in the European corn borer (Ostrinia nubilalis).
Examination of sequence variation at nuclear loci can give insights into population history and gene flow that cannot be derived from other commonly used molecular markers, such as allozymes. Here, we report on sequence variation at a single nuclear locus, the pheromone-binding protein (PBP) locus, in the European corn borer (Ostrinia nubilalis). The European corn borer has been divided into th...
