夏威夷的澳洲坚果(Macadamia integrifolia Maiden and Bet-che)出现了前所未有的新问题:叶片开始轻度褪绿,继而迅速变褐,最后整株树死亡。当有棘胫小蠹[Xyleborus afinis Eichhoff及X.perforans Wol-lastan(Coleoptera:Scolytidae)]侵害和真菌子实体形成后,树势即出现衰退现象。“Ikaika”是最易被侵害的品种。被棘胫小蠹侵害8.3±2.6(SD)个月后植株死亡。
Hawaii’s Macadamia integrifolia Maiden and Bet-che have seen unprecedented new problems: the leaves begin to lightly chlorotic, then quickly brown, and the whole tree dies. Degradation of the tree shores occurs when Xyleborus afinis Eichhoff and X. perforans Wol-lastan (Coleoptera: Scolytidae) infested and fungal fruiting bodies formed. Ikaika is the most vulnerable breed. The plant died after 8.3 ± 2.6 (SD) months of being attacked by Phyllanthus.
