Taxonomic catalogue of the family Ochteridae with description of Ochterus papaceki sp. nov. from Socotra Island and Tanzania (Hemiptera: Heteroptera)
2020
The world catalogue of the family Ochteridae (Hemiptera: Heteroptera: Nepomorpha: Ochteroidea) is compiled. The fossil subfamily Propreocorinae Popov, Dolling & Whalley, 1994, recently excluded from Ochteridae by other authors, is formally raised to family rank as Propreocoridae stat. nov. The fossil genus Meropachys Popov, 1986 is found to be a junior homonym of Meropachys Burmeister, 1835 (Hemiptera: Heteroptera: Coreidae) and is replaced by a new substitute name, Yuripachys nom. nov., resulting in one new combination: Yuripachys dubius (Popov, 1986) comb. nov. Neochterus Mahner, 1993 (originally proposed as subgenus of Ochterus Latreille, 1807) is considered an unavailable name. Ocht…
Hypsipyrgias joseliae, a new species of lace bugs (Heteroptera: Tingidae: Tinginae) from New Guinea with a key to species of the genus Hypsipyrgias, …
2021
Hypsipyrgias joseliae sp. n. (Heteroptera: Tingidae: Tinginae) from New Guinea is described, illustrated and compared with its two relatives, namely H. telamonides Kirkaldy, 1908 from Australia, and H. euphues Drake and Ruhoff, 1962 from Lord Howe Island. Key to species of the genus Hypsipyrgias is also provided. Two genera very closely related to Hypsipyrgias Kirkaldy, 1908, namely Hypsotingis Drake, 1960 and Diplocysta Horváth, 1925 are re-diagnosed. Diplocysta globuliformis Hacker, 1928, D. papuana Drake, 1960, D. rustica, Drake, 1960 and D. thaleia Drake and Ruhoff, 1965 are transferred from Diplocysta to Hypsotingis.
Two new genera and species of the Fulviini (Hemiptera, Heteroptera, Miridae, Cylapinae) from Madagascar, with a checklist of Madagascan cylapines
2022
Two new genera, each represented by a single new species, Cassisotropis aciformis Taszakowski et al. gen. et sp. nov. and Infernotropis madagascariensis Taszakowski et al. gen. et sp. nov. are described from Madagascar. Photographs and SEM micrographs of the male and female habitus, genital structures and selected morphological structures are presented. The first record of Fulvius anthocoroides (Reuter, 1875) in Madagascar and the checklist of Madagascan cylapines are also provided.
Water striders (Heteroptera: Gerromorpha: Gerridae) of Romania with an update on the distribution of Gerris gibbifer and G. maculatus in southeastern…
2018
The Romanian fauna comprises two species of Aquarius Schellenberg, 1800, eight species of Gerris Fabricius, 1794 and one species of Limnoporus Stål, 1868, and we hereby update the distribution and provide insights on the phenology and ecology of all eleven species in this country. We furthermore update the distribution of the two closely related species Gerris gibbifer Schummel, 1832 and G. maculatus Tamanini, 1946 in southeastern Europe. Gerris maculatus is recorded for the first time from Hungary, Montenegro and Slovenia, and the first detailed localities from Romania and Serbia are given. All bibliographic records of G. gibbifer from Romania, Macedonia and Serbia are based on misidentifi…
A study on the genus Macroscytus Fieber, 1860 from China (Hemiptera: Heteroptera: Cydnidae)
2010
Eight species of the genus Macroscytus Fieber, 1860 are reported from China. Among these is M. vietnamicus J.A. Lis, 1991, recorded for the first time from the country; moreover, the occurrence of M. badius (Walker, 1867) in its southern parts (Hainan Province) is confirmed. A key to the Chinese species of the genus is provided, along with habitus figures and illustrations of hind legs and the male genitalia. A phenomenon of instability in the cephalic chaetotaxy of M. aequalis (Walker, 1867), M. badius, M. popovi J.A. Lis, 1991, and M. vietnamicus J.A. Lis, 1994, are briefly discussed.
Plant bugs of the tribe Bothriomirini (Hemiptera: Heteroptera: Miridae: Cylapinae) from the Oriental Region: descriptions of eight new species and ke…
2012
Eight new species of the tribe Bothriomirini are described from the Oriental Region, namely Dashymenia cognata sp. nov., Dashymenia colubrina sp. nov., Dashymenia conspersa sp. nov., Dashymenia tenmalai sp. nov., Dashymenia webbi sp. nov., Dashymeniella spatulatiformis sp. nov., Dashymeniella ulu sp. nov., and Dashymeniella viklundi sp. nov. Five species are redescribed: Bothriomiris dissimulans (Walker), B. lugubris Poppius, B. testaceus Distant, Dashymenia croesus (Distant), and Dashymenia remus (Distant). Illustrations of the male genitalia, a color dorsal habitus photograph of the adult of most species, scanning electron micrographs of selected structures of Bothriomiris dissimulans, Da…
Solid-phase microextraction-liquid chromatography-mass spectrometry applied to the analysis of insecticides in honey
2007
An approach based on solid-phase microextraction-liquid chromatography-mass spectrometry (SPME-LC-MS) has been developed for determining 12 insecticides (bromophos ethyl, chlorpyrifos methyl, chlorpyrifos ethyl, diazinon, fenoxycarb, fonofos, phenthoate, phosalone, pirimiphos methyl, profenofos, pyrazophos, and temephos) in honey. The influence of several parameters on the efficiency of the SPME was systematically investigated. Under optimal conditions, the procedure provided excellent linearity (>0.990), detection and quantification limits (between 0.001 and 0.1 microg g(-1) and between 0.005 and 0.5 microg g(-1), respectively), and precision (<19% at the quantification limits and from 6 t…
Photoelectrocatalyzed degradation of organophosphorus pesticide fenamiphos using WO3 nanorods as photoanode
2020
[EN] In this study, WO3 nanostructures were synthesized by the electrochemical anodization technique to use them on the degradation of persistent organic compounds such as the pesticide fenamiphos. The acids electrolyte used during the anodization were two different: 1.5 M H2SO4-0.05 M H2O2 and 1.5 M CH4O3S-0.05 M H2O2. Once the samples have been manufactured, they have been subjected to different tests to analyze the properties of the nanostructures. With Field Emission Scanning Electron Microscopy (FESEM) the samples have been examined morphologically, their composition and crystallinity has been studied through Raman Spectroscopy and their photoelectrochemical behaviour by Photoelectroch…
Highly Efficient Removal of Neonicotinoid Insecticides by Thioether-Based (Multivariate) Metal–Organic Frameworks
2021
Circumventing the impact of agrochemicals on aquatic environments has become a necessity for health and ecological reasons. Herein, we report the use of a family of five eco-friendly water-stable isoreticular metal-organic frameworks (MOFs), prepared from amino acids, as adsorbents for the removal of neonicotinoid insecticides (thiamethoxam, clothianidin, imidacloprid, acetamiprid, and thiacloprid) from water. Among them, the three MOFs containing thioether-based residues show remarkable removal efficiency. In particular, the novel multivariate MOF {SrIICuII6[(S,S)-methox]1.5[(S,S)-Mecysmox]1.50(OH)2(H2O)}·36H2O (5), featuring narrow functional channels decorated with both -CH2SCH3 and -CH2…
QEC value of the superallowed β emitter 42Sc
2017
The QEC value of the superallowed β+ emitter Sc42 has been measured with the JYFLTRAP Penning-trap mass spectrometer at the University of Jyväskylä to be 6426.350(53) keV. This result is at least a factor of four more precise than all previous measurements, which were also inconsistent with one another. As a byproduct we determine the excitation energy of the 7+ isomeric state in Sc42 to be 616.762(46) keV, which deviates by 8σ from the previous measurement. peerReviewed
