黄杉小卷蛾[Barbara colfaxiana(Kearfott)]、云杉球果螟[Dioryctriaabietivorella(Grote)]、俄州球果瘿蚊(Contarinia oregonensis Foote)及花旗松籽、小蜂(Megastigmus sperm-otrophus Wachtl)是加州种子园重要害虫。黄杉小卷蛾和俄州球果瘿蚊初春羽化,当花旗松进入授粉期,它们便产卵于小球果上。俄州球果瘿蚊幼虫随后侵入球果鳞片,影响胚珠及种子生长发育:黄杉小卷蛾及云杉球果螟的幼虫则可毁灭种子和鳞片。花旗松籽小蜂于春天产卵于发育中的种子,幼虫
Barbara colfaxiana (Kearfott), Dioryctria abietivorella (Grote), Contarinia oregonensis Foote and Douglas fir seeds, Megastigmus sperm-otrophus Wachtl, Is an important pest of the California Seed Park. Lesser Douglas fir and Siraitia grosvenorii mosquitoes early spring eclosion, when Douglas fir entered the pollination period, they spawn on the cones. The S. jackii larva subsequently invade the scaly scales, affecting the ovule and seed growth and development: larvae of the genus Douglas fir and the spruce cone borer can destroy seeds and scales. Douglas-penguin bees in the spring spawning in developing seeds, larvae
