''Larinus filiformis'' is a species of true weevil found in Armenia, Azerbaijan, Turkey, and Bulgaria.〔 〕 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.〔 It is most common at an elevation of 1,000 to 1,400 meters in Turkey. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Larinus filiformis」の詳細全文を読む スポンサード リンク
