Larinus filiformis is a species of true weevil found in Armenia, Azerbaijan, Turkey, and Bulgaria.[1]

The weevil's main host plant in its native range is yellow starthistle Centaurea solstitialis. For this reason, there is interest in determining whether L. filiformis would be a good candidate for classical biological control of the noxious weed. In the field, this weevil has only been reported on yellow starthistle.

Life history

L. filiformis is univoltine in Turkey. Females lay eggs on the flowerheads, and larvae undergo development inside the flower heads. Adults emerge in spring when the temperature reaches about 20 degrees C.[1]

It is most common at an elevation of 1,000 to 1,400 meters in Turkey.

Parasitism

L. filiformis is parasitized by: Bracon urinator (F.), Bracon tshitsherini Kok. (Braconidae), Exeristes roborator Fab. (Ichneumonidae), Aprostocetus sp. (Eulophidae), and unidentified species of Eurytomidae and Ormyridae.[1]

gollark: In the majority of cases, at least, they are the same.

gollark: Well, the current concept of it is connected to that.

gollark: > ...that's what it isNo, it's *somewhat* tied to physical sex.

gollark: yes.

gollark: It would just be some ridiculous arbitrary identifier representing a bunch of something or other.
