Živné rostliny nosatců rodu Hypera (Coleoptera: Curculionidae) vyskytujících se na území ČR

Abstrakt: I review the host plants of the weevil genus Hypera Germar, 1817 from the Czech Republic, based on my own investigation and literature data including previous feeding experiments. Host plants of 22 Hypera species are currently known; 23 host plant species are confirmed. Coronilla varia is recorded as the host plant of Hypera plantaginis (De Geer, 1775) for the first time. Three new host plant species (Medicago falcata, M. sativa and Vicia tenuifolia) are discovered for H. suspiciosa (Herbst, 1795). Some problems with host plants, Chrysaspis and Trifolium spp., of H. venusta (Fabricius, 1781) are commented. New observations on larval development are recorded for H. arator (Linnaeus, 1758) and H. nigrirostris (Fabricius, 1775): the former may feed inside or on the surface of flowers of Dianthus spp.; the latter feed inside unripe flowers of Trifolium pratense and T. repens. The larvae of H. plantaginis develop on Anthyllis, Coronilla, Lotus and Oxytropis spp. from the Fabaceae but not on Plantago spp. from the Plantaginaceae, where they only build the cocoon and pupate. Sixty-five host plants recorded in literature are regarded as incorrect.
