| mitochondrial dna variability and wolbachia infection in two sibling woodlice species | several morphological races and subspecies have been described and later included within the terrestrial isopod species porcellionides pruinosus. during our study of this species, we have worked on specimens from france, greece, tunisia and reunion island. laboratory crosses have revealed two separate groups of populations: french populations (four localities) in one group, and those from tunisia, reunion island and greece in the other. french individuals were reproductively isolated from those ... | 1999 | 10447705 |
| wolbachia diversity in the porcellionides pruinosus complex of species (crustacea: oniscidea): evidence for host-dependent patterns of infection. | porcellionides pruinosus is a cosmopolitan woodlouse. it is known to exhibit patterns of geographical variation between populations, and has been suspected to consist of several very closely related species. this species was found to carry wolbachia endosymbionts, alpha-proteobacteria which are known to modify the reproduction of their crustacean hosts by inducing cytoplasmic incompatibility or feminization. in the p. pruinosus complex, wolbachia induced feminization, but two different patterns ... | 2001 | 11737290 |
| trial of bacillus thuringiensis israelensis, a mosquito larvicide, against porcellionides pruinosus, a terrestrial isopod. | woodlice, porcellionides pruinosus, were not killed when exposed to granular bacillus thuringiensis israelensis. mortality was observed when woodlice received a topical application of the highest concentration of liquid bti, but not at lower concentrations, nor when exposed via contaminated food or contaminated substrates. | 2005 | 16506582 |
| [phenetic analysis of populations of porcellionides pruinosus (brandt, 1833) (crustacea, isopoda, oniscidea)]. | the cosmopolitan species, porcellionides pruinosus (brandt, 1833), exhibited a geographical variation of its morphological features and its reproduction pattern. in fact, some tunisian populations had a seasonal reproductive period and other ones showed a reproductive activity. a phenetic analysis has been performed to compare populations belonging to p. pruinosus from different geographical localities. for this, nineteen quantitative characters in 800 specimens of p. pruinosus issued from nine ... | 2008 | 18280988 |
| isolation, characterization and pcr multiplexing of microsatellite loci for two sub-species of terrestrial isopod porcellio dilatatus (crustacea, oniscidea). | several microsatellite markers have already been developed for different terrestrial isopod species such as armadillidium vulgare, a. nasatum and porcellionides pruinosus. in all these species, the endosymbiont wolbachia has a feminizing effect that generates a female bias in sex ratio and reduces the number of reproductive males. thus this can potentially decrease the genetic diversity of host populations. however, in some other isopod species, wolbachia induces cytoplasmic incompatibility (ci) ... | 2016 | 26943350 |
| widespread atypical mitochondrial dna structure in isopods (crustacea, peracarida) related to a constitutive heteroplasmy in terrestrial species. | metazoan mitochondrial dna (mtdna) is generally composed of circular monomeric molecules. however, a few exceptions do exist and among them two terrestrial isopods armadillidium vulgare and porcellionides pruinosus have an atypical mtdna composed of linear monomers associated with circular "head-to-head" dimers: a very unusual structure for animal mtdna genome. to assess the distribution of this atypical mtdna among isopods, we performed rflp and southern blot analyses on mtdna of 16 terrestrial ... | 2012 | 22376074 |
| toxicity of tributyltin (tbt) to terrestrial organisms and its species sensitivity distribution. | the contamination of the terrestrial environment by disposal of tributyltin (tbt) by contaminated harbour sediments, sewage sludge and/or biocide products has been raising concerns and it may pose a risk to soil invertebrates and plants. this study aimed to improve the amount and quality of data for tbt toxicity in soils in order to assess the ecological risk of tbt to the terrestrial ecosystems. for this, bioassays were performed with the species porcellionides pruinosus, folsomia candida, bras ... | 2014 | 23994735 |
| evaluation of the joint effect of glyphosate and dimethoate using a small-scale terrestrial ecosystem. | in the present work a small-scale terrestrial ecosystem (stem) containing a soil collected from an agricultural field in central portugal was used to evaluate the effects of the combination of the herbicide glyphosate and the insecticide dimethoate. earthworms (eisenia andrei), isopods (porcellionides pruinosus), turnip seeds (brassica rapa), and bait-lamina strips were placed in the stem. the results showed that the application of the recommended field dose of both pesticides did not cause any ... | 2011 | 21724258 |
| ceo2 nanoparticles induce no changes in phenanthrene toxicity to the soil organisms porcellionides pruinosus and folsomia candida. | cerium oxide nanoparticles (ceo2 nps) are used as diesel fuel additives to catalyze oxidation. phenanthrene is a major component of diesel exhaust particles and one of the most common pollutants in the environment. this study aimed at determining the effect of ceo2 nps on the toxicity of phenanthrene in lufa 2.2 standard soil for the isopod porcellionides pruinosus and the springtail folsomia candida. toxicity tests were performed in the presence of ceo2 concentrations of 10, 100 or 1000mg ce/kg ... | 2015 | 25499053 |
| assessing single and joint effects of chemicals on the survival and reproduction of folsomia candida (collembola) in soil. | chemicals are often found in the environment as complex mixtures. there has been a large effort in the last decade to assess the combined effect of chemicals, using the conceptual models of concentration addition and independent action, but also including synergistic, antagonistic, dose-level and dose-ratio dependent deviations from these models. in the present study, single and mixture toxicity of atrazine, dimethoate, lindane, zinc and cadmium were studied in folsomia candida, assessing surviv ... | 2012 | 22035938 |
| joint effects of three plant protection products to the terrestrial isopod porcellionides pruinosus and the collembolan folsomia candida. | the effects of simultaneous application of plant protection products are of concern since the uses of different products pose an additional risk to non-target soil organisms. the effects of binary combinations of dimethoate, glyphosate and spirodiclofen, an insecticide an herbicide and an acaricide, on the avoidance behaviour of the terrestrial isopod porcellionides pruinosus and the reproductive effort of folsomia candida were assessed using the two reference models of concentration addition (c ... | 2010 | 20579688 |
