A. Quiroz et Hm. Niemeyer, OLFACTOMETER-ASSESSED RESPONSES OF APHID RHOPALOSIPHUM-PADI TO WHEAT AND OAT VOLATILES, Journal of chemical ecology, 24(1), 1998, pp. 113-124
Volatiles from wheat and oat seedlings elicited attraction in apterae
and alatae Rhopalosiphum padi. Cereal volatiles were identified by CC-
MS and olfactometric tests were performed with each compound. Attracti
on of aphids was elicited by (E)-2-hexenyl acetate, (Z)-3-hexenol, (E)
-2-hexenyl acetate, (E)-2-hexenol, (Z)-2-hexenol, n-heptanal, n-octana
l, n-nonanal, n-decanal, benzaldehyde, and linalool. The difference be
tween the sensory capacity of alatae and apterae is discussed in relat
ion to migrations between hosts during their life cycle.
