圆柏大痣小蜂是危害圆柏属树木种子的寡食性昆虫,除成虫期外,其卵、幼虫和蛹均生活在种子之内,防治难度较大。为找出防治有效适期,经观察测算,从幼虫化蛹的始、盛、末期到羽化的始、盛、末期历时35天;从成虫羽化始盛期至盛末期历时8天。此间成虫暴露于种子外部,是防治的最佳时期。 The pollinator wasps are the insectivorous insects infesting the seeds of the Sabina przewalskii. Except adult stages, their eggs, larvae and pupae all live within the seeds, making it more difficult to control. In order to find out the effective period of prevention and treatment, the larval pupation started from the beginning, the peak and the end of the larvae to the beginning, the peak and the end of the eclosion for 35 days. From the beginning of adult eclosion to the end of the peak, it lasted for 8 days. Adults here exposed to the outside of the seeds, is the best time to control.
