“…Z8-12:OH is 10% of the pheromone blend, so it probably has few dedicated ORNs that were missed in our sampling of 176 sensilla, or these neurons were not very specific or housed in sensilla other than trichodea (e.g., sensilla auricillica in Cydia pomonella (L.), Ebbinghaus et al, 1997;Ansebo et al, 2005), which were not sampled in our study. Whereas narrow variations in the ratio of the two acetates have a strong effect in male behavioral response (Baker et al, 1981;Knight et al, 2014a), males accept wide variations in the quantity of Z8-12:OH in the blend Linn and Roelofs, 1983;Linn et al, 1986), and in some locations Z8-12:OH is produced in trace amounts by females (Lacey and Sanders, 1992), or does not seem to play a role in attraction (Han et al, 2001;Jung et al, 2013). Furthermore, other alcohols affect the response of male G. molesta to the two acetates Cardé et al, 1975aCardé et al, ,b, 1979, including the sex pheromone of C. pomonella (Knight et al, 2014b), and Z8-12:OH inhibits males of closely related species (Grapholita funebrana (Treitschke) and Grapholita prunivora (Walsh)), that use a similar ratio of the Z/E acetates as G. molesta Guerin et al, 1986), so a reinvestigation of the role of alcohols in the olfactory communication of G. molesta is warranted.…”

“…It has been proposed that host plant volatiles mediate male attraction to mating sites either by themselves, before the onset of pheromone release by females, or by synergizing the response to sex pheromone (Landolt and Phillips 1997;Reddy and Guerrero 2004;Beyaert and Hilker 2014). In some species, host plant volatiles increase male attraction toward sex pheromone Light et al 1993;Yang et al 2004;Schmidt-Büsser et al 2009;Varela et al 2011;von Arx et al 2012), whereas they produce an antagonistic effect in other species (Pregitzer et al 2012;Jung et al 2013;Party et al 2013;Rouyar et al 2015). It is conceivable that volatiles from nonhost plants (Wang et al 2016), volatiles from damaged plants, such as DMNT (Fig.…”

Plant odor and sex pheromone are integral elements of specific mate recognition in an insect herbivore

Specific mate recognition relies on the chemical senses in most animals, and especially in nocturnal insects. Two signal types mediate premating olfactory communication in terrestrial habitats: sex pheromones, which blend into an atmosphere of plant odorants. We show that host plant volatiles affect the perception of sex pheromone in males of the African cotton leafworm Spodoptera littoralis and that pheromone and plant volatiles are not perceived as independent messages. In clean air, S. littoralis males are attracted to single synthetic pheromone components or even the pheromone of a sibling species, oriental cotton leafworm S. litura. Presence of host plant volatiles, however, reduces the male response to deficient or heterospecific pheromone signals. That plant cues enhance discrimination of sex pheromone quality confirms the idea that specific mate recognition in noctuid moths has evolved in concert with adaptation to host plants. Shifts in either female host preference or sex pheromone biosynthesis give rise to new communication channels that have the potential to initiate or contribute to reproductive isolation.

Plant odour and sex pheromone are 1 integral elements of specific mate 2 recognition in an insect herbivore Summary 16 Specific mate recognition strongly relies on the chemical senses in many animals, and 17 especially in nocturnal insects. Two signal types lend to premating olfactory 18 communication in terrestrial habitats: sex signals blend into an atmosphere of habitat 19 odorants, where plant volatiles prevail. We show for the first time that males of the 20 African cotton leafworm Spodoptera littoralis perceive female sex pheromone and 21 volatiles of its plant host cotton as a unit, rather than as independent messages. In clean 22 air, S. littoralis males are attracted to flawed pheromone signals, such as single synthetic 23 pheromone components or even the pheromone of a sibling species, Oriental leafworm S. 24 litura. Presence of host plant volatiles, however, strongly reduces the male response to 25 deficient or heterospecific pheromone signals. That plant cues enhance discrimination of 26 Borrero et al. -p. 2 sex pheromone quality confirms the idea that specific mate recognition in noctuid moths 27 has evolved in concert with host plant adaptation. A participation of host plant odour in 28 sexual communication suggests that mate recognition is under natural and sexual 29 selection. Moreover, shifts in either female host preference or sex pheromone 30 biosynthesis give rise to new communication channels that have the potential to initiate 31 or contribute to reproductive isolation. 32 Key words: premating sexual communication, specific mate recognition, reproductive 33 isolation, ecological speciation 34 (N=50) were released individually from glass tubes at the downwind end of the tunnel. 132 Males were scored for upwind flight over 150 cm, up to ca. 30 cm from the odour source. 133Synthetic odour blends were delivered from the centre of the upwind end of the wind 134 tunnel from a piezo-electric sprayer (El-Sayed et al. 1999; Becher et al. 2010). Samples 135 were loaded into a 1-ml glass syringe operated by a microinjection pump (CMA 136 Microdialysis AB, Solna, Sweden) that delivered test solutions at a constant rate of 10
