Exon capture coupled to high-throughput sequencing constitutes a cost-effective technical solution for addressing specific questions in evolutionary biology by focusing on expressed regions of the genome preferentially targeted by selection. Transcriptome-based capture, a process that can be used to capture the exons of non-model species, is...

Background: The spread of agriculture greatly modified the selective pressures exerted by plants on phytophagous insects, by providing these insects with a high-level resource, structured in time and space. The life history, behavioural and physiological traits of some insect species may have evolved in response to these changes, allowing them...

Insect invasion biology and agriculture are intimately related because many agricultural insect pests are recent invaders. In this presentation, we propose to summarize some of the main results that were recently obtained in ecology and evolutionary biology that are important to understand invasions. We also present population genetics studies...

Public confidence in genetically modified (GM) crop studies is tenuous at best in many countries, including those of the European Union in particular. A lack of information about the effects of ties between academic research and industry might stretch this confidence to the breaking point. We therefore performed an analysis on a large set of...

Population genetic methods are widely used to retrace the introduction routes of invasive species. The unsupervised Bayesian clustering algorithm implemented in STRUCTURE is amongst the most frequently used of these methods, but its ability to provide reliable information about introduction routes has never been assessed. We simulated...

Chez le melon, il existe une résistance, conférée par le gène Vat 2 , à la colonisation par le puceron Aphis gossypii. Cette résistance s'exprime d'une part par une antixénose 3 et d'autre part par une antibiose 4 . Des variétés possédant ce gène sont commercialisées depuis plus de 10 ans, et on peut donc craindre le développement de pucerons...
