The box tree moth, Cydalima perspectalis (Lepidoptera: Crambidae), is native to East Asia and was introduced in Europe more than a decade ago. It causes severe damage to box trees (Buxus spp.) in both urban and natural habitats. The occurrence of this invasive pest in southeastern Europe has not been documented in a comprehensive way yet. The main...

The North American oak lace bug feeds on leaves of ‘white oaks” in its native range. In Europe, it was first discovered in northern Italy in 2000. In recent years, it has subsequently spread rapidly and population outbreaks have been observed in several European countries. In the present study, we summarize the steps of its expansion. To predict it...

A rovarok és környezetük kapcsolata rendkívül szoros, ezért ha abban-például a klímaváltozás miatt-a legkisebb változás is bekövetkezik, arra érzékenyen reagálnak. Ez a reakció igen változatos lehet. Megváltozhat elterjedési területük, megváltozhat fejlődési idejük és ezen keresztül a generációs viszonyaik, illetve a populáció nagyságát befolyásoló...

Population fluctuations of the well-known oak defoliator, the oak processionary moth (Thaumetopoea processionea L.), were studied using light trap data and basic meteorological parameters (monthly average temperatures, and precipitation) at three locations in Western Hungary over a period of 15 years (1988-2012). The fluctuations in the numbers cau...

Kivonat Az észak-amerikai tölgy csipkéspoloskát (Corythucha arcuata) Európában először Észak-Olaszországban észlelték (2000). Magyarországon 2013-ban találták meg, az azóta eltelt öt évben, különösen pedig 2016-ban és 2017-ben gyors terjeszke-dést mutatott. 2017 őszéig öt kivételével (Borsod-Abaúj-Zemplén, Nógrád; Győr-Moson-Sopron, Vas és Veszprém...

As global biodiversity continues to decline steeply, it is becoming increasingly important to understand diversity patterns at local and regional scales. Changes in land use and climate, nitrogen deposition and invasive species are the most important threats to global biodiversity. Because land use changes tend to benefit a few species but impede m...

Erdészeti Lapok CLI. évf. 12. szám (2016. december) 420 A gyapjaslepke " naptár szerint esedé-kes " tömegszaporodása idén is elma-radt, holott a 2003–2006-os tömegszapo-rodás óta eltelt idõ, illetve az utóbbi né-hány év idõjárása alapján joggal várhat-tuk volna. A kellemes csalódást minden bizonnyal az Entomophaga maimaiga rovarpatogén gombának kös...

Spectral mating preferences were examined in male Agrilus angustulus (Buprestidae:Coleoptera), a member of a taxon known for its high species diversity and striking metallic coloration. The spectral emission profile of a typical A. angustulus female displays low chroma, broadly overlapping that of the green oak leaves they feed and rest upon, while...

Background and Purpose: Despite the importance of studying the native enemy complex of the introduced and invasive leaf miner sawfly species in their native territories, few studies have been done in recent years concerning the species component and the regulating potential of their parasitoid complexes (in both native and invaded area). Heterarthr...

Between 2011 and 2014, 1,154 mines of Phyllonorycter comparella (Duponchel) were collected at 12 locations in Hungary and were put into single-mine rearing containers. A total of 574 parasitoid specimens belonging to 29 parasitoid species (26 Chalcididae, 2 Encyrtidae and 1 Braconidae) emerged. Of these species, 13 have not yet been mentioned in ei...

Phyllonorycter issikii (Lepidoptera: Gracillariidae) has recently spread over a considerable part of the Eurasian continent. So far, in Europe, unlike in Russia, it has not significantly affected its food plant (Tilia cordata), but its effect may increase over time. The regulating potential of associated parasitoid natural enemies is still low, whi...

Kontinensünkön növekvõ ütemben jelennek és honosodnak meg behurcolt kártevõk és kórokozók. Ezek jelentõs része rövidebb-hosszabb idõ alatt hazánkat is eléri. A szélsõséges idõjárású évek (súlyos aszályok, enyhe telek stb.) hatására olyan honos rovarok és kórokozók léphetnek fel tömegesen, amiket korábban jelentéktelennek, " ártatlannak " tartottunk...

The box tree moth (Cydalima perspectalis) is one of the insect species alien to Europe which have already caused significant damage in many parts of the continent only a few years after their introduction. The aim of our study was to reveal the distribution area of the pest in Hungary in 2012–2013. The monitoring project was coordinated by the Depa...

Leaf miners are good models to study multitrophic interactions, including the regulating potential of their parasitoids. Only a few works have been published concerning the parasitoids of the Central European and Hungarian leaf miners. In 2011 and 2012 we studied the parasitoid complexes of 9 leaf mining species developing on 4 different species of...

108 alien insect species with real or potential importance for forestry have been recorded in Hungary between 1881 and 2010. The colonization rate steeply increased in the last 2-3 decades. More new species were recorded in the last 30 years (1981-2010) than in the previous 100 years (1881-1980). Order Hemiptera (particularly aphids) represent the...
