Summary 1. The view of post‐mining sites is rapidly changing among ecologists and conservationists, as sensitive restoration using spontaneous succession may turn such into biodiversity refuges in human‐exploited regions. However, technical reclamation, consisting covering the by topsoil, sowing fast‐growing herb mixtures planting trees, still commonly adopted. Until now, no multi‐taxa study has compared technically reclaimed left with succession. 2. We sampled communities vascular plants 10...
A new monotypic genus of flatid planthoppers (Hemiptera: Fulgoromorpha: Flatidae), Medleria gen. nov., is described for caudata et sp. nov. (type species) from the island Socotra (Yemen). Habitus, male and female external internal genital structures species are illustrated compared with similar taxa. probably endemic to where it known date a small area Dixam mountain plateau only
Three new species of gall-forming psyllids (Hemiptera: Psylloidea) in the families Triozidae and Phacopteronidae are described from Papua New Guinea: Trioza incrustata Percy, sp. nov. makes enclosed leaf margin galls on Celtis philippensis (Cannabaceae), grallata surface Elaeocarpus schlechterianus (Elaeocarpaceae), Cornegenapsylla allophyli Malenovský Allophylus cobbe (Sapindaceae). Descriptions adult immature morphology for these provided, differences between sinica Yang Li, 1982 (the type...
The Asian citrus psyllid Diaphorina citri (Insecta: Hemiptera: Psylloidea), a serious pest of species worldwide, harbors vertically transmitted intracellular mutualists, Candidatus Profftella armatura (Profftella_DC, Gammaproteobacteria: Burkholderiales) and Carsonella ruddii (Carsonella_DC, Oceanospirillales). Whereas Carsonella_DC is typical nutritional symbiont, Profftella_DC unique defensive symbiont with organelle-like features, including localization within the host, perfect infection...
The predominantly tropical tribe Paurocephalini of jumping plant-lice currently consists seven genera and 94 described species worldwide, which the Klyveria Burckhardt et al. Melanastera Serbina have been recorded from Brazil with two one species, respectively. Here we review taxonomy Brazilian based on material collected extensive fieldwork carried out in 15 states over last decade. One 59 are newly described, bringing number extant spp. to three (both worldwide) that 69 (60 Brazil, 67...
Abstract Using molecular (COI, Cytb, H3, wg, 12S, 16S, and 28S) morphological data (61 characters of adults immatures), the phylogenetic relationships 20 nominal genera Liviinae were analysed, monophyly subfamily was tested relative to other two subfamilies Liviidae. The analyses molecular, morphological, combined datasets provided similar results with a strong or moderate support in for Liviidae clades given tribal rank (Liviini Paurocephalini stat. rev.). Three six previously recognized...
The Afrotropical planthopper genus Centromeriana Melichar, 1912 (Hemiptera, Fulgoromorpha, Dictyopharidae, Dictyopharinae, Orthopagini) is revised. Four species are included: C. jocosa (Gerstaecker, 1895) (the type species, with confirmed records from Cameroon, Equatorial Guinea and Gabon), lindbergae sp. nov. (described Sierra Leone), rhinoceros Togo) simplex (so far only known Guinea, Bioko island). Lectotypes designated for both redescribed including habitus photographs detailed...
Livestock grazing is one of the most common management practices for grasslands and can greatly affect their biodiversity. However, arthropod diversity response patterns to regimes are difficult predict. We conducted a short-term exclusion experiment in traditionally managed alkali Hungary investigate differences between grazed ungrazed vegetation different groups. The was laid out full factorial design, with twelve 50 × 100 m exclosures types high (alkali wet meadow) low productivity...
Psyllids are phloem-feeding insects that can transmit plant pathogens such as phytoplasmas, intracellular bacteria causing numerous diseases worldwide. Their microbiomes essential for insect physiology and may also influence the capacity of vectors to pathogens. Using 16S rRNA gene metabarcoding, we compared three sympatric psyllid species associated with pear trees in Central Europe. All able 'Candidatus Phytoplasma pyri', albeit different efficiencies. Our results revealed potential...
Abstract We studied the use of a supervised artificial neural network (ANN) model for semi-automated identification 18 common European species Thysanoptera from four genera: Aeolothrips Haliday (Aeolothripidae), Chirothrips Haliday, Dendrothrips Uzel, and Limothrips (all Thripidae). As input data, we entered 17 continuous morphometric two qualitative two-state characters measured or determined on different parts thrips body (head, pronotum, forewing ovipositor) sex. Our experimental data set...
Abstract Jumping plant lice (Hemiptera: Psylloidea) are known for a few deleterious pest species worldwide, yet the phylogeny of group has been poorly understood until very recently. Here, we reconstruct higher‐level superfamily Psylloidea based on multilocus DNA sequences, three mitochondrial (COI‐tRNA leu ‐COII, 12S, 16S) and five nuclear (18S, 28S D2, D3, D6–7a, D9–10) gene fragments, using maximum likelihood Bayesian inference phylogenetic frameworks. Our results largely congruent with...
Abstract Pear psyllids (Hemiptera: Psylloidea: Psyllidae: Cacopsylla spp.) belong to the most serious pests of pear ( Pyrus spp.). They damage trees by excessive removal phloem sap, soiling fruits with honeydew which, in turn, provides a substrate for sooty mould, and transmission Candidatus Phytoplasma spp., causal agents decline disease. The morphological similarity, presence seasonal dimorphism that affects adult colour, size wing morphology uncritical use species names, led much...
Abstract Psyllids, or jumping plant lice (Hemiptera: Sternorrhyncha: Psylloidea), are a group of small phytophagous insects that include some important pests crops worldwide. Sexual communication psyllids occurs via vibrations transmitted through host plants, which play an role in mate recognition and localization. The signals species‐specific can be used to aid psyllid taxonomy pest control. Several hypotheses have been proposed for the mechanism generates these vibrations, stridulation,...
Even after decades of research on diversification in the Neotropics, our understanding evolutionary processes shaping Neotropical clades is still incomplete. In current study, we used different divergence times and likelihood-based methods to investigate influence biogeography host associations most species-rich psyllid genus Melanastera (Liviidae) using molecular phylogenetic data from seven gene fragments (four mitochondrial three nuclear). The putatively monophyletic group species has an...
The Neotropical proconiine sharpshooter genus Abana includes six previously described species, some of which have nearly identical male genitalia but differ in coloration. taxonomy the is here revised based on comparative morphological study and phylogenetic analysis partial mitochondrial COI sequences coupled with following molecular species delimitation methods: ABGD, ASAP, PTP (including bPTP) GMYC. Phylogenies for implementation tree-based methods were hypothesized maximum likelihood...
