Tracking mite trophic interactions by multiplex PCR
2020
Background A thorough knowledge of trophic webs in agroecosystems is essential to achieve successful biological pest control. Phytoseiid mites are the most efficient natural enemies of tetranychid mites, which include several important pests worldwide. Nevertheless, phytoseiids may feed on other food sources including other microarthropods, plants and even other phytoseiids (intraguild predation), which can interfere with biological control services. Molecular gut content analysis is a valuable tool for characterizing trophic interactions, mainly when working on microarthropods such as mites. We have designed new primers for Phytoseiidae, Tetranychidae and Thysanoptera identification and th…
Past and current distribution of Charaxes jasius jasius (Linnaeus, 1767) (Lepidoptera Nymphalidae) in Sicily in relation to its host plant, Arbutus u…
2022
The authors provide an updated overview of the past and present regional distribution of the two-tailed Pasha Charaxes jasius jasius (Linnaeus, 1767) (Lepidoptera Nymphalidae) and its host plant, the strawberry tree Arbutus unedo L. Most of the occurrence data reported in the entomological literature was confirmed, and several new populations have been recently dis- covered. The distribution pattern of the insect and its host plant overlap almost perfectly. C. jasius jasius is more abundant and forms large and stable populations on the Peloritani Mts. and in some areas of the Madonie Mountains. The high number of new records of C. jasius jasius suggests that the species is experiencing a sp…
Pluskwiaki różnoskrzydłe (Hemiptera: Heteroptera) zimujące pod korą platanów klonolistnych Platanus x acerifolia w Polsce
2020
The paper presents the results of three-year studies conducted at 75 locations in Poland testing the use of the London planes for overwintering of true-bugs. Insects were sampled from the bark of trunks. Altogether 25 species of Heteroptera was recorded, including three invasive species that can considerable affect plane trees: Arocatus longiceps, Corythucha ciliata and Oxycarenus lavaterae.
The associations of quantitative/qualitative job insecurity and well-being: The role of self-esteem.
2019
Job insecurity is recognized as one of the most prominent job stressors for employees. Despite decades of research, the concurrent examination of both quantitative (i.e. perceived threat of job loss) and qualitative (i.e., perceived threat of losing some job features) job insecurity and the analysis of their different relationships with well-being at work have received relatively scarce attention. This study examined a moderated mediation model of the relationship between quantitative job insecurity and well-being at work. In doing so, the focus was on the mediating effects of qualitative job insecurity and the moderating effects of self-esteem in the abovementioned relationships. Drawing f…
Alarmist by bad design: Strongly popularized unsubstantiated claims undermine credibility of conservation science
2019
“Unless we change our ways of producing food, insects as a whole will go down the path of extinction in a few decades.” or “Our work reveals dramatic rates of decline that may lead to the extinction of 40% of the world's insect species over the next few decades.” These are verbatim conclusions of the recent paper by Sánchez-Bayoa and Wyckhuys (2019) in Biological Conservation. Because of fundamental methodological flaws, their conclusions are unsubstantiated. Like noted by The Guardian, the conclusions of the paper were set out in unusually forceful terms for a peer-reviewed scientific paper. The current case…
Validating of a hetero- and self-evaluation tool for teaching organization
2021
Il contributo presenta uno strumento di etero-auto-valutazione della capacità di organizzazione dell’insegnamento in classe, che è stato usato per misurare negli insegnanti in formazione le abilità di previsione e sviluppo di un intervento didattico, di regolazione e riflessione sulla pratica. Osservare e decidere, pensare che cosa, perché e come insegnare, progettare e valutare in modo autentico, sono operazioni complesse e determinanti per creare l’humus organizzativo e metodologico che caratterizza lo sviluppo professionale dell’insegnante, anche riguardo alle competenze comunicative e riflessive (Perrenoud, 2012; Conole, 2014; Panke, 2019). La rating scale, con le azioni da osservare, è…
Equilibres divariants entre la vapeur d'eau et les hydrates solides : Caractérisation de la nature de la solution solide, limites du domaine de divar…
1972
National audience; Nous avons récemment proposé (1, 2) deux modèles thermodynamiques pour les équilibres divariants entre la vapeur d'eau et les hydrates salins solides. Le premier postule l'existence d'une solution solide d'insertion d'eau dans le sel, le second postule l'existence d'une solution solide de substitution entre deux hydrates du sel. Le but de ce travail est d'établir un nouveau critère permettant de distinguer les deux modèles à partir de l'expérience et de délimiter le domaine divariant dans chacun des deux cas. Nous supposerons, sauf mention contraire, que la solution d'insertion obéit à la loi de Henry par rapport à l'eau et que la solution de substitution est idéale. Nous…
Multiple modalities in insect warning displays have additive effects against wild avian predators
2019
Allocation to different components of defence has been suggested as an explanation for the existence of multiple aposematic morphs in a single population. We tested whether there are trade-offs between warning colouration and chemical defence or whether these have an additive effect when combined, using blue tits (Cyanistes caeruleus) as predators and the polymorphic wood tiger moth (Arctia plantaginis) as prey. We used artificial edible models (with and without the moths’ defensive fluids) with paper wings whose colour and pattern properties matched those of real moths. When the models were presented sans defensive fluids or when the fluids were presented without colour cues, we detected n…
Genomic structure and promoter analysis of pathogen-inducedrepatgenes fromSpodoptera exigua
2009
The repat gene family encodes midgut proteins overexpressed in response to pathogen infection in the lepidopteran Spodoptera exigua. Up-regulation of repat genes has been observed after challenging the larvae with both Bacillus thuringiensis toxins and after infection with the baculovirus Autographa californica multiple nucleopolyhedrovirus. In our study, PCR amplification of the genomic region and genome walking were used to obtain the genomic structure and the sequence of the 5'-upstream region of repat1 and repat2, two of the most phylogenetically distant members of the repat family. A similar gene structure between repat1 and repat2 has been found, with conserved exon-intron positions a…
Modulation of Hepatitis C Virus NS5A Hyperphosphorylation by Nonstructural Proteins NS3, NS4A, and NS4B
1999
NS5A of the hepatitis C virus (HCV) is a highly phosphorylated protein involved in resistance against interferon and required most likely for replication of the viral genome. Phosphorylation of this protein is mediated by a cellular kinase(s) generating multiple proteins with different electrophoretic mobilities. In the case of the genotype 1b isolate HCV-J, in addition to the basal phosphorylated NS5A (designated pp56), a hyperphosphorylated form (pp58) was found on coexpression of NS4A (T. Kaneko, Y. Tanji, S. Satoh, M. Hijikata, S. Asabe, K. Kimura, and K. Shimotohno, Biochem. Biophys. Res. Commun. 205:320‐326, 1994). Using a comparative analysis of two full-length genomes of genotype 1b…
