Abstract

Pests from South America recorded for the first time on ornamental plants in Polish greenhouses are presented: Florida red scale (Chrosomphalus aonidum [Chrysomphalus aonidum]), fern scale (Pinnaspis aspidistrae), slug-caterpillar moths (Scopelodes contracus [Scopelodes contracta] and Sibine stimulea [Acharia stimulea]), and Australian cockroach (Periplaneta australasiae) on Dracaena; Florida wood cockroach (Eurycotis floridana) and leafrollers (Amorbia and Platynota spp.) on Schefflera; leafroller moth (Epagoge grotiana) and American thrips (Echinothrips americanus) on azalea (Rhododendron sp.); and noctuid moth (Chrysodeixis chalcites) on Zebrina pendula. Native pests that have become economically important consisted of: woolly aphids (Pemphigidae) on roots of junipers (Juniperus), pines (Pinus), and spruces (Picea); weevils (Otiorhynchus spp.) on azaleas and coniferous plants; a lymantriid moth (Orgyia antiquoidea) on Erica tetralix; bud and leaf nematode (Aphelenchoides ritzemabosi) on Virgin's bowers, Hydrangea petiolarisHydrangea anomala], Philadelphus coronarius, and some perennial plants. The minerfly (Phytomyza ranunculi) on Virgin's bowers and Ranunculus acris, the azalea leafminer (Caloptilia azaleella) on rhododendrons (Rhododendron), the locust midge (Dasineura gleditchiae) on honey locust [Gleditsia triacanthos], the aster mite (Phytonemus pallidus asteris) on Aster dumosus and A. novi-belgii, and the broad mite (Polyphagotarsonemus latus) on potted plants were also identified as important pests. The horse chestnut miner (Cameraria ohridella) was recorded for the first time on nursery-grown horse chestnut [Aesculus hippocastanum. Phyllonorycter robiniella and Parectopa robiniella occurred on white locust.
