ANTAGONISME ANTARA KUMBANG AMBROSIA XYLEBORUS SP. DAN JAMUR BIRU YANG MENYERANG DOLOK TUSAM (PINUS MERKUSII)

Paimin Sukartana

Sari


freshly  cut  logs of  tusam (Pinus merkusii) are very susceptible to the  infestation  of  the ambrosia beetle Xyleborus  sp.  and blue stain fungi.   An observation  showed that  both wood deteriorating organisms might infest a same log simultaneously,  but  they did  not inhabit  the same area.  They have their own  area which are separated  from  one to  another.  There is an indication  tha  any parts of  logs having  been  infested  by  the fungi. will not be suitable any more for  the beetle's  host  It seems thal the ambrosia  beetle is deterred  or  repelled  by  the  presence  of  the blue stain fungi infestation,  or  at  least,  the  beetle  responds  unfavorably  to  the  fungi.
