Dlhokrčky (Raphidioptera) Ostrova Kopáč
VIDLIČKA, Ľ. 2007: Dlhokrčky (Raphidioptera) ostrova Kopáč Dlhokrčky (Raphidioptera) ostrova Kopáč (Bratislava) Ľubomír VIDLIČKA Ústav zoológie SAV, Dúbravská cesta 9, 845 06 Bratislava e-mail: [email protected] Úvod Dlhokrčky (Raphidioptera) sú veľmi malá skupina hmyzu (okolo 200 druhov, 2 čeľade) rozšírená hlavne v palearktickej oblasti (Európa, Ázia), menej v holoarktickej oblasti (len na západe USA) a okrajovo v orientálnej oblasti. Larvy aj dospelce sú suchozemskými predátormi. Larvy väčšiny druhov žijú pod kôrou stromov a krov, zriedkavo aj na povrchu pôdy a v skalných puklinách. Imága sú charakteristické predĺženou predohruďou (od toho je odvodený slovenský názov). Je to malý až stredne veľký hmyz, v rozpätí krídiel dosahujú 1-4 cm. Zo Slovenska je doteraz známych len 9 druhov z 2 čeľadí (ZELENÝ, 1977). Zo susednej Moravy je známych 10 druhov. Druh Parainocellia braueri (ALBARDA, 1891) zistený na južnej Morave (CHLÁDEK, ZELENÝ, 1995; ŠEVČÍK, 1997) sa pravdepodobne tiež vyskytuje na juhu Slovenska. Výskum dlhokrčiek nebol doteraz na Slovensku systematicky robený. Prvé konkrétne údaje prináša MOCSÁRY (1899) vo Fauna regni Hungariae. Zo Slovenska uvádza 4 druhy (Raphidia notata, Raphidia ophiopsis, Raphidia flavipes a Raphidia xanthostigma). PONGRÁCZ (1914) uvádza z územia Slovenska už 7 druhov (doplnil Raphidia major, Raphidia ratzeburgi a Inocellia crassicornis). Posledné dva druhy doplnili BARTOŠ (1967) (A. nigricollis) a ZELENÝ (1977) (Raphidia cognata = confinis). BARTOŠ (1965) opísal zo Slovenska (z Lozorna na západnom Slovensku) dokonca nový druh dlhokrčky Raphidia barbata, ale ten bol o pár rokov synonymizovaný s druhom Raphidia ophiopsis LINNAEUS, 1758, ktorý je veľmi variabilný (ZELENÝ, 1969). Z okolia Bratislavy sú z literatúry známe iba dva druhy - Raphidia flavipes z Bratislavy a Raphidia major zo Sv. -

Root Weevils Ryan Davis Arthropod Diagnostician
Published by Utah State University Extension and Utah Plant Pest Diagnostic Laboratory ENT-193-18 May 2018 Root Weevils Ryan Davis Arthropod Diagnostician Quick Facts • Root weevils are a group of small, black-to-brown weevils that commonly damage ornamental and small fruit plants in Utah. • Adult root weevil damage is characterized by marginal leaf notching and occasional feeding on buds and young shoots. • Larval root weevil damage occurs below ground; damage to roots can lead to canopy decline or plant death. • Root weevils are occasional nuisance pests in homes and structures mid-summer through fall. • Manage root weevil larvae by applying a systemic insecticide to the soil around host plants April through September. • Adults feeding on the above-ground portion of plants can be targeted with pyrethroid pesticides Black vine weevil adult (Kent Loeffler, Cornell University, Bugwood.org) starting in late June or early July. IDENTIFICATION INTRODUCTION Root weevils are small beetles ranging in length from about 1/4 to 1/3 inch depending on The black vine weevil (Otiorhynchus sulcatus), species. Coloration is variable, but the commonly lilac root weevil (O. meridionalis) strawberry weevil encountered species in Utah are black with gold (O. ovatus) and rough strawberry root weevil (O. flecks (black vine weevil) or solid brown to black, rugosostriatus) are a complex of non-native, snout- shiny or matte. As a member of the weevil family nosed beetles (Coleoptera: Curculionidae) that (Curculionidae), these pests have a snout, but it cause damage to ornamentals and small fruit crops is shortened and rectangular compared to other in Utah. Root weevils are occasional nuisance pests weevils that have long, skinny mouthparts. -

GIS-Based Modelling Reveals the Fate of Antlion Habitats in the Deliblato Sands Danijel Ivajnšič1,2 & Dušan Devetak1
www.nature.com/scientificreports OPEN GIS-based modelling reveals the fate of antlion habitats in the Deliblato Sands Danijel Ivajnšič1,2 & Dušan Devetak1 The Deliblato Sands Special Nature Reserve (DSSNR; Vojvodina, Serbia) is facing a fast successional process. Open sand steppe habitats, considered as regional biodiversity hotspots, have drastically decreased over the last 25 years. This study combines multi-temporal and –spectral remotely sensed data, in-situ sampling techniques and geospatial modelling procedures to estimate and predict the potential development of open habitats and their biota from the perspective of antlions (Neuroptera, Myrmeleontidae). It was confrmed that vegetation density increased in all parts of the study area between 1992 and 2017. Climate change, manifested in the mean annual precipitation amount, signifcantly contributes to the speed of succession that could be completed within a 50-year period. Open grassland habitats could reach an alarming fragmentation rate by 2075 (covering 50 times less area than today), according to selected global climate models and emission scenarios (RCP4.5 and RCP8.5). However, M. trigrammus could probably survive in the DSSNR until the frst half of the century, but its subsequent fate is very uncertain. The information provided in this study can serve for efective management of sand steppes, and antlions should be considered important indicators for conservation monitoring and planning. Palaearctic grasslands are among the most threatened biomes on Earth, with one of them – the sand steppe - being the most endangered1,2. In Europe, sand steppes and dry grasslands have declined drastically in quality and extent, owing to agricultural intensifcation, aforestation and abandonment3–6. -

Medler INTRODUCTION HIS bulletin attempts to present as accurate and complete a T guide to the leafhoppers of Minnesota as possible within the limits of the material available for study. It is realized that cer- tain groups could not be treated completely because of the lack of available material. Nevertheless, it is hoped that in its present form this treatise will serve as a convenient and useful manual for the systematic and economic worker concerned with the forms of the upper Mississippi Valley. In all cases a reference to the original description of the species and genus is given. Keys are included for the separation of species, genera, and supergeneric groups. In addition to the keys a brief diagnostic description of the important characters of each species is given. Extended descriptions or long lists of references have been omitted since citations to this literature are available from other sources if ac- tually needed (Van Duzee, 1917). -
Prey Recognition in Larvae of the Antlion Euroleon Nostras (Neuroptera, Myrrneleontidae)

The larva reacted to the prey with several behavioural patterns. The larva recognized its prey at a distance of 3 to 15 cm from the rim of the pit without seeing it, and was able to determine the target angle. The greatest distance of sand tossing was 6 cm. Responsiveness to the substrate vibration caused by the bug Pyrrhocoris apterus was very low. 1. Introduction efficient motion for antlion is to toss sand over its back (Lucas 1989).
