    First annotated checklist of Chironomidae of Rhodos, Greece (Insecta, Diptera)

    Chironomid fauna of Greek Aegean islands, an essential part of the biogeographically important Mediterranean region, is almost unexplored, with only 36 species recorded prior to the present study. It is especially true for Dodecanese islands (6 recorded species). In 2007, chironomid larvae and exuviae were collected in Rhodos, the largest member of the Dodecanese islands. Thirty-four taxa were identified (8 Tanypodinae, 10 Orthocladiinae, 16 Chironominae). None of the previously recorded taxa were found; thus all collected species proved to be new for the fauna of Rhodos. An actualized checklist for the Chironomidae of Rhodos is given based on the literature and results of recent investigations

    Social Conflict Generating Ecological Developments in the Life of Lake Balaton in Recent Decades – Mass Swarming of Non-biting Midges. The mass swarming of adult non-biting midges (Diptera: Chironomidae) can cause strong inconvenience to tourists, disturbing them in resting and recreational activities and often forcing them to leave home earlier than they planned. This problem negatively affects the local businesses, resulting in a claim to the extermination of chironomids. Due to the fact that chironomids are essential for a healthy functioning of the ecosys-tem of Lake Balaton, the public claim is in contradiction with environmental protec-tion and nature conservation. However, possibilities for controlling the swarming do exist. As a first step of controlling measures, the study on the temporal pattern of swarming has been started in 2010. The characteristics of swarming during the last three years were described. The dominant species, Chironomus balatonicus caused the most problem at Lake Balaton. However, the swarming of this species showed high year-to-year variation. On the other hand, long-term data on swarming are not available for Lake Balaton, thus it cannot be determined whether the huge swarming recently observed is exceptional or shows a rising tendency. | Az utĂłbbi 5–6 Ă©vben a kivĂ©telesen hosszĂș idƑn keresztĂŒl Ă©s nagy mennyisĂ©gben rajzĂł ĂĄrvaszĂșnyogok szĂĄmos gondot okoztak a Balaton tĂ©rsĂ©gĂ©ben. Tömegeik kĂ­vĂŒlrƑl-belĂŒlrƑl elleptĂ©k az Ă©pĂŒleteket, helyisĂ©geket, gĂ©pjĂĄrmƱveket, Ă©s a vĂ­zparton nem lehetett semmifĂ©le tevĂ©kenysĂ©get folytatni. A nyĂ­lt vĂ­zen a horgĂĄszok Ă©s a vitorlĂĄzĂłk szĂĄmĂĄra okoztak problĂ©mĂĄt, aminek egyik extrĂ©m esete volt, hogy a 2010-ben az ĂĄrva-szĂșnyogok jelentƑs mĂ©rtĂ©kben hozzĂĄjĂĄrultak ahhoz, hogy a Balatoni KĂ©kszalag vitorlĂĄsversenyt szĂĄmos versenyzƑ feladta. Sok vendĂ©g az ĂĄrvaszĂșnyogok ĂĄltal okozott kellemetlensĂ©gek miatt idƑ elƑtt eltĂĄvozott a part menti szĂĄllĂĄshelyekrƑl. Mindezek miatt felmerĂŒlt az igĂ©ny az ĂĄrvaszĂșnyogok irtĂĄsĂĄra, ami viszont termĂ©szetvĂ©delmi szempontbĂłl nem ajĂĄnlott, sƑt, kifejezetten hibĂĄs megoldĂĄs lenne

    Occurrence of rare caddisfly (Trichoptera) species at the catchment area of Lake Balaton

    Get PDF
    Although the caddisfly fauna of previously undiscovered regions in Hungary have adequately been explored, there are many regions (e.g. Great Hungarian Plain) and water types (e.g. backwaters of rivers, springs) whose caddisfly fauna is poorly known so far. In addition, occurrence of new species can be recorded in relatively well known regions as well. Although caddisfly fauna of catchment area of Lake Balaton is relatively well explored, during the most recent intensive faunistical investigations several rare and endangered caddisfly species were found. In this paper a compilation of formerly published results and new larval data are given on the following rare caddisfly species in Hungary: Synagapetus krawanyi, Hydropsyche siltalai, Apatania muliebris, Limnephilus elegans, Silo nigricornis, Adicella reducta, Beraea maurus
