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[edit]
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 °C (68 °F).[1]
It is most common at an elevation of 1,000 to 1,400 metres (3,300 to 4,600 ft) in Turkey.
Parasitism[edit]
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]
