Excluding Ponto-Caspian species originating in brackish waters and freshwater subterranean taxa, there are 11 formally recognized epigean freshwater species recorded from this country. They belong to 3 genera, each representing a different family: Gammarus (Gammaridae, 8 species or species complexes), Niphargus (Niphargidae, 2 epigean species) and Synurella (Crangonyctidae, one species). Their large-scale distribution patterns nevertheless remain obscure due to insufficient data, consequently limiting biogeographical interpretations. We provide extensive new data with high resolution distribution maps, thus improving the knowledge of the ranges of these taxa. -
Vertical Transmission of a Dimorphic Microsporidium (Microspora) in the Mormon Cricket, Anabrus Simplex (Orthoptera: Tettigoniid
Vertical transmission of a dimorphic microsporidium (Microspora) in the Mormon cricket, Anabrus simplex (Orthoptera: Tettigoniidae) by Francoise Djibode A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in Entomology Montana State University © Copyright by Francoise Djibode (1993) Abstract: The Mormon cricket, Anabrus simplex is an endemic pest of crops and rangelands in the western United States. It occurs mostly in environmentally sensitive areas where biological control options are desirable. A dimorphic microsporidium was found in this cricket and appears to be useful for such control. My hypotheses state that this dimorphic microsporidium infects adult crickets and causes mortality. It also affects cricket fecundity and the viability of their progeny, and is vertically transmitted. Increasing dosages of the spores were fed to young adult crickets, and the infection status of their progeny was checked by phase contrast microscopy. Reproductive organs from male and female crickets infected orally with 107 spores each were fixed after 40 and 49 days and checked for the presence of the pathogen. Infection of young adult crickets ranged from 22.5% at 105 to 82.5% at 109 spores/cricket. The infection rate doubled and increased from 35% to 72.5% when 106 spores/cricket and 107 spores/cricket were applied, respectively. The dose required to infect 50% of adult crickets (ID50) was 106.4 spores/cricket. Mortality of the treated crickets increased from 30% to 82.5% for untreated versus treated with 109 spores/cricket. The dimorphic microsporidium had a significant adverse effect on cricket fecundity and reduced the number of eggs produced by 57.6% when 105 and 109 spores were applied, respectively. -

Editorial note On the publication “On the current state of taxonomy of the Baikal Lake amphipods (Crustacea, Amphipoda) and the typological ways of constructing their system” by V.V. Takhteev In this issue we present an extensive article prepared by Prof. Vadim V. Takhteev, which is based on his long time effort in the study of diversity of amphipods in Lake Baikal and its watershed. This paper is highly polemical and may even seem either archaic or heretical in the time of domination of the phylogenetic paradigms in systematics. The author advocates classical morphological taxonomy, which own tradition, methods (disregarding whether we call it typology or not) and the language are significantly older than the modern phylogenetic approach. -

RESUMEN El parásito microsporidio Nosema ceranae, hasta hace algunos años fue considerado como patógeno de Apis cerana solamente, sin embargo en el último tiempo se ha demostrado que puede afectar con gran virulencia a Apis mellifera. Por esta razón, ha sido denunciado como un agente patógeno activo en la desaparición de las colonias de abejas en el mundo, infectando a todos los miembros de la colonia. Es importante mencionar que las abejas son ampliamente utilizadas para la polinización y la producción de miel, de ahí su importancia en la agricultura, además de desempeñar un papel ecológico importante en la polinización de las plantas donde un tercio de los cultivos de alimentos son polinizados por abejas, al igual que muchas plantas consumidas por animales. En este contexto, esta revisión pretende resumir la información generada por diferentes autores con relación a distribución geográfica, características morfológicas y genéticas, sintomatología y métodos de control que se realizan en aquellos países donde está presente N. ceranae, de manera de tener mayores herramientas para enfrentar la lucha contra esta nueva enfermedad apícola. Palabras clave: parásito, microsporidio, Apis mellifera, Nosema ceranae. SUMMARY Up until a few years ago, the microsporidian parasite Nosema ceranae was considered to be a pathogen of Apis cerana exclusively; however, only recently it has shown to be very virulent to Apis mellifera. -

A new microsporidian pathogen of the cabbage butterfly,Pieris brassicae is described based on light microscopy, ultrastructural characteristics and comparative small subunit rDNA analysis. The pathogen infects the gut of P. brassicae. All development stages are in direct contact with the host cell cytoplasm. Meronts are spherical or ovoid. Spherical meronts measure 3.68 ± 0.73 × 3.32 ± 1.09 µm and ovoid meronts 4.04 ± 0.74 × 2.63 ± 0.49 µm. Sporonts are spherical to elongate (4.52 ± 0.48 × 2.16 ± 0.27 µm). Sporoblasts are elongated and measure 4.67 ± 0.60 × 2.30 ± 0.30 µm in length. Fresh spores with nuclei arranged in a diplokaryon are oval and measure 5.29 ± 0.55 µm in length and 2.31 ± 0.29 µm in width. Spores stained with Giemsa’s stain measure 4.21 ± 0.50 µm in length and 1.91 ± 0.24 µm in width. Spores have an isofilar polar filament with six coils. All morphological, ultrastructural and molecular features indicate that the described microsporidium belongs to the genus Nosema and confirm that it has different taxonomic characters than other microsporidia infecting Pieris spp. -

Continental-Scale Patterns of Hyper-Cryptic Diversity
www.nature.com/scientificreports OPEN Continental‑scale patterns of hyper‑cryptic diversity within the freshwater model taxon Gammarus fossarum (Crustacea, Amphipoda) Remi Wattier1*, Tomasz Mamos2,3, Denis Copilaş‑Ciocianu4, Mišel Jelić5, Anthony Ollivier1, Arnaud Chaumot6, Michael Danger7, Vincent Felten7, Christophe Piscart8, Krešimir Žganec9, Tomasz Rewicz2,10, Anna Wysocka11, Thierry Rigaud1 & Michał Grabowski2* Traditional morphological diagnoses of taxonomic status remain widely used while an increasing number of studies show that one morphospecies might hide cryptic diversity, i.e. lineages with unexpectedly high molecular divergence. This hidden diversity can reach even tens of lineages, i.e. hyper cryptic diversity. Even well‑studied model‑organisms may exhibit overlooked cryptic diversity. Such is the case of the freshwater crustacean amphipod model taxon Gammarus fossarum. It is extensively used in both applied and basic types of research, including biodiversity assessments, ecotoxicology and evolutionary ecology. Based on COI barcodes of 4926 individuals from 498 sampling sites in 19 European countries, the present paper shows (1) hyper cryptic diversity, ranging from 84 to 152 Molecular Operational Taxonomic Units, (2) ancient diversifcation starting already 26 Mya in the Oligocene, and (3) high level of lineage syntopy. Even if hyper cryptic diversity was already documented in G. fossarum, the present study increases its extent fourfold, providing a frst continental‑scale insight into its geographical distribution and establishes several diversifcation hotspots, notably south‑eastern and central Europe. The challenges of recording hyper cryptic diversity in the future are also discussed. In many areas of biology, including biodiversity assessments, eco-toxicology, environmental monitoring, and behavioural ecology, the species status of the studied organisms relies only on a traditional morphological defnition1. -
Protistology the Path to Registration of a Microbial Pesticide
Protistology 11 (3), 175–182 (2017) Protistology The path to registration of a microbial pesticide John E. Henry* Devils Lake, ND, 58301, USA | Submitted October 2, 2017 | Accepted October 16, 2017 | Summary This paper presents a historical account of our attempt to develop a pathogenic microsporidium, Nosema locustae (now Paranosema locustae), as a microbial pesticide for reducing the frequency and scope of outbreaks of grasshoppers in the US. The objective was to provide program managers with another tool for altering grasshopper densities. As a result of our investigations, in 1980 the Environmental Protection Agency of the USA (EPA) issued the registration of a product containing Nosema locustae spores as the active ingredient, and in 1990 the Reregistration Eligibility Document (RED) that summarized all of the information behind the rational for using N. locustae and the pertinent evidence relating to the registration of this organism. Biological insecticide NOLO BAIT is used for grasshopper control all over the world, and is considered one of the most effective grasshopper baits.

Two helminth parasites com- monly use this crustacean species as second intermediate host. One of them, Coitocaecum parvum,isa progenetic trematode with an egg-producing metacercaria occasionally reaching 2.0 mm in length, i.e. more than 50% the typical length of its amphipod host. The amphipod was shown to exhibit the common reproductive features of most precopula pair-forming crustaceans, i.e. larger males and females among pairs than among singles, more fecund females in pairs, and a trend for size-assortative pairing.
