Figure 5. Performance of biologically-derived O.
nubilalis sex pheromone. A. Electrophysiological responses of
male O. nubilalis antennae to biologically-derived pheromone
blend (BioPhe), standard compounds (Z 11-14:OAc, E 11-14:OAc
and 14:OAc), and mixtures of the standard compounds. Response to 100 ng
of Z 11-14:OAc was defined as 100%, and all responses normalized
in % relative to this reference. Means followed by the same letter are
not significantly different (P> 0.5, Tukey’s studentized
range [HSD] test, F=51.650, df=5, P=0.000) B . Behavioral
responses of O. nubilalis males to yeast-derived pheromone blend
(BioPhe), standard compounds (Z 11-14:OAc, E 11-14:OAc,
14:OAc) and mixtures of the standard compounds. Phe 97:3 represents
pheromone composition originally found in O. nubilalis Z-race and
is generated from standard compounds Z 11-14:OAc,E 11-14:OAc in ratio 97:3. Means followed by the same letter are
not significantly different (P> 0.05, Tukey’s studentized
range [HSD] test). Approach, F=4.579 df=3, P=0.005, Landing,
F=5.899, df=3, P=0.001)
