Journal ArticleDOI
On the mechanism of Wolbachia-induced cytoplasmic incompatibility: confronting the models with the facts.
TL;DR: The lock-and-key model is the most parsimonious of the models and fits the observations best, and the two other models cannot be categorically invalidated, but they encounter some difficulties that make additional hypotheses necessary.
Journal ArticleDOI
Costs of secondary parasitism in the facultative hyperparasitoid Pachycrepoideus dubius: does host size matter?
TL;DR: It is hypothesized that the size of D. melanogaster pupae parasitized by A. tabida may be close to the suboptimal host size for P. dubius beneath which the costs of hyperparasitism make this strategy nonadaptive.
Journal ArticleDOI
The Toxin–Antidote Model of Cytoplasmic Incompatibility: Genetics and Evolutionary Implications
John F. Beckmann,Manon Bonneau,Hongli Chen,Mark Hochstrasser,Denis Poinsot,Hervé Merçot,Mylène Weill,Mathieu Sicard,Sylvain Charlat +8 more
TL;DR: The tight association of the CI genes with prophages provides clues to the possible evolutionary origin of this phenomenon and the levels of selection at play.
Journal ArticleDOI
Patch exploitation strategies of parasitic wasps under intraspecific competition
TL;DR: In competitive situations, some members of the population tended to retreat almost immediately from the patch whereas other members tended to remain, further exploit the patch, and be more involved in interactions with conspecifics.
Journal ArticleDOI
Identification of a widespread monomolecular odor differentially attractive to several Delia radicum ground-dwelling predators in the field.
Antonin Ferry,Sébastien Dugravot,Thomas Delattre,Jean-Philippe Christidès,Jacques Auger,Anne-Geneviève Bagnères,Denis Poinsot,Anne-Marie Cortesero +7 more
TL;DR: Attractiveness of this widespread compound was tested in the field in a naturally complex odorous environment using an original setup especially designed for ground dwelling beetles and the use of general linear model (GLM) statistics permitted us to finely discriminate the responses among the different treatments.
