Sm. Kimani et al., Airborne volatiles from Melinis minutiflora P. Beauv., a non-host plant ofthe spotted stem borer, J ESSEN OIL, 12(2), 2000, pp. 221-224
Airborne volatiles released by Melinis minutiflora P. Beauv., a non-host pl
ant of the spotted stem borer, Chilo partellus (Swinhoe), were trapped from
the live plant by air entrainment into porous polymer Porapak Q and analyz
ed by GC and GC/MS. The main hydrocarbons identified and confirmed by co-in
jection with authentic samples on two columns of different polarities were
(3E)-4,8-dimethylnona-1,3,7-triene (28.1% of isolated volatiles) and beta-c
aryophyllene (24.2% of isolated votatiles). Of these, (3E)-4,8-dimethylnona
-1,3,7-triene is electroantenographically active (EAG) against Chilopartell
us (Swinhoe).
