Abstract
Larinus sibiricus Gyllenhal is a poorly known weevil distributed in eastern Europe and in the Middle East. Its biology and host plants are studied in northeastern Turkey for the first time. The main host of this weevil is Xeranthemum annuum L. (Asteraceae). In northeastern Anatolia, L. sibiricus produces one generation yearly. Females lay eggs in flowerheads; larvae feed on flower parts; pupal stage is undergone in the flowerhead. Teneral adults, after a several-day delay, emerge from the flowerhead and hide under stone or in some other shelter for hibernation. Bracon urinator (F.) (Hymenoptera: Braconidae) parasitoid wasp have been reared from larval stage. In the preliminary host preference test, L. sibiricus preferred X. annuum.
