The parasitic mite, Varroa destructor, is the most serious pest of western honey bee, Apis mellifera, and has caused death millions colonies worldwide. This mite reproduces in brood cells parasitizes immature adult bees. We investigated whether infestation induces changes mellifera gene expression, there are genotypic differences that affect expression relevant to bee's tolerance, as first steps toward unravelling mechanisms host response susceptibility parasitism. explored transcriptional...
Correct identification of the source population an invasive species is a prerequisite for testing hypotheses concerning factors responsible biological invasions. The native area may be large, poorly known and/or genetically structured. Because actual not have been sampled, studies based on molecular markers generate incorrect conclusions about origin introduced populations. In this study, we characterized genetic structure ladybird Harmonia axyridis in its using various statistics and...
The species status of Tetranychus cinnabarinus remains uncertain for some acarologists. In the present paper, we propose to examine taxonomic this tetranychid mite through a review studies that aimed clarify its taxonomical position. We and discuss main results concerning principal aspects investigated throughout literature published since description Boisduval in 1867. These concern morphological, biological molecular data which have been used separate or synonymise T. urticae. Additional...
Plant biosecurity is increasingly challenged by emerging crop pests. The spider mite Tetranychus evansi has recently emerged as a new threat to solanaceous crops in Africa and the Mediterranean basin, with invasions characterized high reproductive output an ability withstand wide range of temperatures. Mitochondrial (868 bp COI) nuclear (1,137 ITS) loci were analyzed T. samples spanning current geographical distribution study earliest stages invasive process. two sets markers separate into...
The two-spotted spider mite Tetranychus urticae is one of the most significant pests in agriculture, feeding on more than 1,100 plant hosts, including model plants Arabidopsis thaliana and tomato, Solanum lycopersicum. Here, we describe timecourse tomato transcriptional responses to compare them with order determine conserved divergent defense this pest. To refine involvement jasmonic acid (JA) mite-induced improve Gene Ontology annotations, analyzed changes JA-signaling mutant defenseless1...
The spider mite Tetranychus evansi is an emerging pest of solanaceous crops worldwide. Like many other pests, its small size, confusing taxonomy, complex history associations with humans, and propensity to start new populations from inocula, make the study invasion biology difficult. Here, we use recent developments in Approximate Bayesian Computation (ABC) variation multi-locus genetic markers reconstruct historical demography this cryptic invasive pest. By distinguishing among multiple...
Significance Patterns of host use by parasites are commonly thought to be limited phylogenetic constraints, yet little is known about the role geographic distribution hosts and in such patterns. We show that evolutionary patterns a family plant largely determined geographical parasites. Such lability results repeated colonizations distantly related lineages, even across major transitions. Still, these transitions constitute significant adaptive barriers evolution use. Our thus parasitic...
Abstract Climate change (CC) clearly impacts food production, but risks on the climatic suitability of agricultural areas for vegetable crops, their pests and associated natural enemies are largely unexplored. Tomato, one most important vegetables in world, is grown mostly outdoors, may be severely impacted by CC. Farmers cultivating tomatoes need to adapt an increase potential outbreaks favoured CC disruption biological control, yet, no attempt has been made simultaneously evaluate effects...
ABSTRACT Using a combination of the cytochrome oxidase subunit I gene (COI) and internal transcribed spacer (ITS) sequence information, cross-breeding, morphological criteria, taxonomic status Tetranychus takafujii was reassessed. Described from Japan very close to evansi, only male empodium II separated two species. Six T. evansi samples collected in Brazil, France, Kenya, Spain (including Canary Islands), Taiwan, previously species-identified as takafujii, were examined. DNA sequences...
Abstract This article documents the addition of 283 microsatellite marker loci to Molecular Ecology Resources Database. Loci were developed for following species: Agalinis acuta ; Ambrosia artemisiifolia Berula erecta Casuarius casuarius Cercospora zeae‐maydis Chorthippus parallelus Conyza canadensis Cotesia sesamiae Epinephelus acanthistius Ficedula hypoleuca Grindelia hirsutula Guadua angustifolia Leucadendron rubrum Maritrema novaezealandensis Meretrix meretrix Nilaparvata lugens...
Many species are shifting their distributions due to climate change and increasing international trade that allows dispersal of individuals across the globe. In case agricultural pests, such range shifts may heavily impact agriculture. Species distribution modelling help predict potential changes in pest distributions. However, these strategies subject large uncertainties coming from different sources. Here we used tomato red spider mite (Tetranychus evansi), an invasive affects some most...
Adapting to specific hosts often involves trade-offs that limit performance on other hosts. These constraints may either lead narrow host ranges (i.e. specialists, able exploit only one type) or wide leading lower each generalists). Here, we combined laboratory experiments field populations with experimental evolution investigate the impact of adaptation range and associated over this range. We used two-spotted spider mite, Tetranychus urticae, a model organism for studies specialization....
Abstract Recent studies on Wolbachia-induced incompatibility in haplodiploid insects and mites have revealed a diversity of cytoplasmic (CI) patterns among host species. Here, we report intraspecific CI expression four strains the arrhenotokous mite Tetranychus urticae T. turkestani. Variability within ranged from no to complete CI, included either female embryonic mortality or male conversion types CI. A fecundity cost attributed infection with high-CI Wolbachia strain was highest ever...
The majority of Coccinellidae are beneficial predators and they have received considerable research attention because their potential as biological control agents. Indeed the role coccinellids pest insects has been a major factor in movement between countries. commercial production by companies local producers led to rapid increase distribution thoughout 1990's. To date, 13 alien coccinellid species documented Europe; 11 these Europe (two Great Britain Sweden but native within Europe)....
Collection efforts in the framework of European All Taxa Biodiversity Inventory conducted Mercantour national Park located Alps mountain range southern France disclosed three new species Tetranychid mites. The described current paper are: Bryobia cinereae n. sp., mercantourensis sp. and Eotetranychus quercicola sp.. Both were collected on Genista cinerea E. Quercus pubescens. A combination is also proposed for longisetis, previously placed Pseudobryobia by Wainstein (1960).
