Alternative host plants for Ostrinia nubilalis Hbn.and Diabrotica v. virgifera LeConte beetles in southern Poland

摘要

The aim of the research was to study the host plants for the Ostrinia nubilalis larvae and Diabrotica v. virgifera beetles in southern Poland. The feeding of O. nubilalis larvae was confirmed on the following cultivated plants: Humulus lupulus, Malusdomestica, Rubus idaeus, Panicum miliaceum, Capsicum annuum, Rheum rhabarbarum, Sorghum vulgare and Vitis vinifera. Larvae damaged the most plants of the H. lupulus. In addition, the larvae also feed on the following weeds: Artemisia vulgaris, Echinochloa crus-galli, Chenopodium album, Chenopodium polyspermum, Hyoscyamus niger, Atriplex patula, Arctium tomentosum, Solanum nigrum, Polygonum persicaria, Polygonum lapathifolium, Amaranthus retroflexus and Rumex crispus. The most individuals were found in stems of A. vulgaris. Diabrotica virgifera beetles mainly sought for pollen on the following cultivated plants: Citrullus lanatus, Cucurbita pepo convar. giromontiina, Cu-curbita pepo, Phaseolus vulgaris, Calendula officinalis, Cucumis melo, Cucumis sativus, Helianthus annuus and Helianthus tuberosus. The most individuals were found on cucurbits. In addition, adults occurred on the following weeds: E. crus-galli, C. album, C. polyspermum, Sonchus arvensis, Taraxacum officinale, Solidago virgaurea, Cirsium arvense, Amaranthus retroflexus, Setaria glauca, Setaria viridis and Galinsoga parviflora.
