-. This plant is involved in a nursery pollination system, because a noctuid moth, Hadena bicruris, is not only pollinator but also seed predator. [[http://www.leffingwell.com/chirality/lilacaldehyde.htm|Lilac aldehyde]] is the key floral scent compound of S. latifolia for attracting Hadena.... In all samples only the (5'S)-configured stereoisomers were detected, and no (5'R)-configured stereoisomer was found. The most abundant isomer in all samples was either the (2S,2'S,5'S)- or the (2R,2'S,5'S)-configured stereoisomer. Both isomers reached a relative amount of ca. 40%, followed by isomer (2'S,2'R,5'S) with ca. 20% relative amount. The fourth isomer, (2R,2'R,5'S), occurred only in small amounts (0.7–3.0%)." \\
+"... Hadena bicruris is attracted to the flowers of its most important host plant, Silene latifolia, by their scent... Phenylacetaldehyde elicited the strongest signals in the antennae, but lilac aldehydes were the most attractive compounds in wind-tunnel bioassays and attracted 90% of the moths tested, as did the scent of single flowers." \\
+Main components of the flower scent were benzaldehyde, myrcene, (Z)-3-hexenyl acetate, β-ocimene, phenylacetaldehyde, guaiacol, veratrole, lilac aldehydes, benzyl acetate, 3-phenylpropanal, lilac alcohols, and (E,E)-α-farnesene. \\

 The most dominant compounds (reaching a relative amount of 20% at least in one sample) in the 18 studied populations were lilac aldehyde, benzyl acetate, veratrole, phenylacetaldehyde, and E-(ß)-ocimene. \\
