Larinus filiformis occurs in Armenia, Azerbaijan, Turkey, and Bulgaria and has been reared only from C. solstitialis. At field sites in central and eastern Turkey, adults were well synchronized with the plant, being active from mid-May to late July and ovipositing in capitula (flowerheads) of C. solstitialis from mid-June to mid-July. Larvae destroy all the seeds in a capitulum. The insect is univoltine in Turkey, and adults hibernate from mid-September to mid-May. In the spring, before adults begin ovipositing, they feed on the immature flower buds of C. solstitialis, causing them to die. The weevil destroyed 25-75% of capitula at natural field sites, depending on the sample date. Preliminary host specificity experiments on adult feeding indicate that the weevil seems to be restricted to a relatively small number of plants within the Cardueae. Approximately 57% of larvae or pupae collected late in the summer were parasitized by hymenopterans (Bracon urinator, B. tshitsherini (Braconidae) and Exeristes roborator (Ichneumonidae), Aprostocetus sp. (Eulophidae), and unidentified species of Eurytomidae and Ormyridae). This weevil may be a better choice than the other capitula insects already established in the United States, particularly in colder parts of the plant's range.10aLarinus filiformis1 aGültekin, L.1 aCristofaro, M.1 aTronci, C.1 aSmith, L.  uhttps://weevil.myspecies.info/natural-history-studies-preliminary-evaluation-larinus-filiformis-coleoptera-curculionidae-prospecti00651nas a2200145   4500008004100000245017600041210006900217300000900286490000800295100001800303700001600321700001900337700001400356856013500370       2008                        eng d00aBroad-nosed weevils feeding on Centaurea solstitialis L. in Turkey, with a description of the new species Araxia cristofaroi sp. n.
