Előzetes adatok néhány mediterrán díszcserje kártevő és hasznos ízeltlábú faunájához

Abstract

Arthropod species on two different sampling sites (Keszthely, Cserszegtomaj), for two years (2016, 2017) have been collected with beating method from the canopy of five different Mediterranean evergreen shrubs (Ligustrum sinense, Phyllirea angustifolia, Elaeagnus pungens, Prunus lusitanica, Photinia x fraseri). Our aim was to identify the arthropod species, which has already chosen these shrubs, as food plants and became their pests in Hungary and in addition to it we were curious to know the species spectrum of beneficial arthropods. The data are still being processed, so only the most significant, most common species are presented in this study. In the case of the two shrubs (Ligustrum sinens, Phyllirea angustifolia), belonging to the Oleaceae family, Dendrothrips ornatus thrips species can be considered a potential pest. Among Planthoppers (Auchenorrhyncha) a large number of Fieberiella florii (Cicadellidae) and Metcalfa pruinosa (Flatidae) were present. Among the spring pests, the Phyllobius weevil species caused significant damage primarily on shrubs (Prunus lusitanica, Photinia x fraseri) belonging to the Rosaceae family. Mainly the Phyllobius betulinus, but a large number of P. maculicornis and P. oblongus were also present. The Dodecastichus (= Otiorhynchus) mastix weevil occurred in high numbers mostly on the two shrubs belonging to the Oleaceae family. Among the predators there were a large number of earwigs (Dermaptera) (Forficulidae family), true bugs (Heteroptera) (several families), within the order of the beetles (Coleoptera) the lady beetles (Coccinellidae), within the order hymenopterans (Hymenoptera) the ants (Formicidae) and within the chelicerates (Chelicerata) the spiders (Araneae) present.
