The biology of weevil species, Larinus onopordi (F.) living on globe thistle Echinops sphaerocephalus L. was described for the first time. The species is univoltine, adults overwinter under hiding object as aggregated. Eggs are inserted into the flowerhead; L. onopordi deposited eggs superficially, 1-23 (3.76) eggs each capitulum may be occur in one flowerhead, larvae develop in capitulum eating and destroying the seeds. In late summer, larvae complete their growth; prepare pupal case 1-4 (0.84) case in each flowerhead and pupation occurs in here. New generation adults emerge from flowerhead after waited several days. Thus, this weevil has one generation per year in northeastern Turkey. A braconid wasp, Bracon facialis Thom. (Hymenoptera: Braconidae) reared from the pupal stage of L. onopordi. none
