Hibernation places and behavior of the some weevil species (Coleoptera: Curculionidae)
Abstract
Hibernation places and behavior of the 40 species of weevil from subfamilies Lixinae, Ceutorhynchinae, Baridinae, Gymnetrinae and Entiminae (Curculionidae) were determined in Eastern Turkey during 1997–2007. Larinus latus (Herbst), L. fucatus Faust, Lixus ochraceus Boheman, L. furcatus Olivier, L. obesus Petri, L. siculus Boheman, L. korbi Petri, and Mononychus schoenherri Kolenati prefer to migrate by flight before hibernation. Cleonis pigra (Scopoli), Larinus onopordi (Fabricius), L. inaequalicollis Capiomont, L. ochroleucus Capiomont, L. sibiricus Gyllenhal, L. sp. n. pr. leuzeae Fabre, L. filiformis Petri, Herpes porcellus Lacordaire and Mononychus punctumalbum (Herbst) display aggregation behavior under stone, bark, plants or in soil. Conorhynchus hololeucus (Pallas), Mecaspis incisuratus Gyllenhal, Leucosomus pedesteris (Poda), Otiorhynchus brunneus Steven, O. latinasus Reitter hibernate under stones and in plant litter. Gymnetron netum (Germar) and Larinus puncticollis Capiomont hide for hibernating in the larval galleries of Lixus circumcinctus in dry plant stem of Crambe orientalis, and Lixus myagri — in the root system of Lepidum latifolium, respectively. Glocianus transcaucasicus Korotyaev, Ceutorhynchus inaffectatus Gyllenhal and C. rapae Gyllenhal hide in soil cells, Baris goekseli Korotyaev et Gültekin and Melanobaris crambephaga (Korotyaev et Gültekin) also hibernate in soil. Mogulones gnom Khnzorian and M. lineatus (Gyllenhal) hide under rosette plants. Lixus cardui Olivier, L. filiformis (Fabricius), L. myagri (Olivier) and L. circumcinctus Boheman hibernate in their host plants stems or rootcrown without forming pupal cells. Lixus bardanae (Fabricius) and L. sp. n. pr. korbi Petri emerge from their host plants and hide under the litter of the same host plant for hibernation. All weevil species presented here hibernate in adult stage.
