Competition for food affects the strength of reproductive interference and its ...
Cruz, Miguel A.; Godoy, Oscar; De mendonça fragata almeida, Inês; Sousa, Vitor C; Magalhães, Sara; Zélé, FloreCompetition for food and reproductive interference (negative interspecific sexual interactions) have been identified as major drivers of species exclusion. Still, how these biotic interactions jointly determine competitive dominance remains largely unknown. We tackle this by coupling population models and laboratory experiments with two sibling species of spider mites. Using experiments specifically designed to...
Wolbachia strengthens the match between premating and early postmating isolatio...
Cruz, Miguel; Magalhães, Sara; Bakırdöven, Murat; Zélé, FloreEndosymbiotic reproductive manipulators are widely studied as sources of post-zygotic isolation in arthropods, but their effect on pre-zygotic isolation between genetically differentiated populations has garnered less attention. We tested this using two partially isolated populations of the red and green colour forms of Tetranychus urticae, either uninfected or infected with different Wolbachia strains, one ind...
Interspecific interactions among parasites in multiple infections
Duncan, Alison B.; Godoy, Oscar; Michalakis, Yannis; Zélé, Flore; Magalhães, SaraIndividual hosts and populations frequently harbour multiple parasite species simultaneously. Despite their commonness, the consequences of interspecific interactions among parasites for determining infection outcomes are still poorly understood. We review and propose several expectations for multiple infections involving different species. We highlight that interspecific interactions affect the outcome of comp...
A Sex‐Specific Trade‐Off Between Pesticide Resistance and Tolerance to Heat‐Ind...
Costa, Sofia G.; Magalhães, Sara; Santos, Inês; Zélé, Flore; Rodrigues, Leonor RCurrent pest management relies extensively on pesticide application worldwide, despite the frequent rise of pesticide resistance in crop pests. This is particularly worrisome because resistance is often not costly enough to be lost in populations after pesticide application, resulting in increased dependency on pesticide application. As climate warming increases, effort should be put into understanding how heat...
No evidence for the evolution of mating behavior in spider mites due to Wolbach...
Rodrigues, Leonor R; Zélé, Flore; Santos, Inês; Magalhães, SaraArthropods are often infected with Wolbachia inducing cytoplasmic incompatibility (CI), whereby crosses between uninfected females and infected males yield unviable fertilized offspring. Although uninfected females benefit from avoiding mating with Wolbachia-infected males, this behavior is not always present in host populations and its evolution may hinge upon various factors. Here, we used spider mites to tes...
Wolbachia and host intrinsic reproductive barriers contribute additively to pos...
Cruz, Miguel; Magalhães, sara; Sucena, Élio; Zélé, FloreWolbachia are maternally-inherited bacteria that induce cytoplasmic incompatibility in many arthropod species. However, the ubiquity of this isolation mechanism for host speciation processes remains elusive, as only few studies have examined Wolbachia-induced incompatibilities when host populations are not genetically compatible. Here, we used three populations of two genetically differentiated colour forms of ...

Inter- and intraspecific variation of spider mite susceptibility to fungal infe...
Zélé, Flore; Altıntaş, Mustafa; Santos, Inês; Cakmak, Ibrahim; Magalhães, saraSpider mites are severe pests of several annual and perennial crops worldwide, often causing important economic damages. As rapid evolution of pesticide resistance in this group hampers the efficiency of chemical control, alternative control strategies, such as the use of entomopathogenic fungi, are being developed. However, while several studies have focused on the evaluation of the control potential of differ...
Population‐specific effect of Wolbachia on the cost of fungal infection in spid...
Zélé, Flore; Altıntaş, Mustafa; Santos, Inês; Cakmak, Ibrahim; Magalhães, SMany studies have revealed the ability of the endosymbiotic bacterium Wolbachia to protect its arthropod hosts against diverse pathogens. However, as Wolbachia may also increase the susceptibility of its host to infection, predicting the outcome of a particular Wolbachia-host-pathogen interaction remains elusive. Yet, understanding such interactions and their eco-evolutionary consequences is crucial for disease...
Creating outbred and inbred populations in haplodiploids to measure adaptive re...
Godinho, Diogo; Cruz, Miguel A.; Charlery de la Masselière, Maud; Teodoro‐Paulo, Jéssica; Eira, Cátia; De mendonça fragata almeida, InêsLaboratory studies are often criticized for not being representative of processes occurring in natural populations. One reason for this is the fact that laboratory populations generally do not capture enough of the genetic variation of natural populations. This can be mitigated by mixing the genetic background of several field populations when creating laboratory populations. From these outbred populations, it ...
