“…In the present study, we explored the possibility of weak ultrasound production by courting male moths. We showed that the production of weak ultrasounds is much more widespread among moths than previously assumed, because nine of 13 tested species produced sounds in close proximity to a female, after showing typical female sex pheromone-mediated mating behaviors (Yushima and Tamaki, 1974;Seol et al, 1986;Witjaksono et al, 1999;Samudra et al, 2002;Shirai, 2006).…”

SUMMARYUltrasonic hearing is widespread among moths, but very few moth species have been reported to produce ultrasounds for sexual communication. In those that do, the signals are intense and thus well matched for long distance communication. By contrast, males of the Asian corn borer moth (Crambidae) were recently shown to whisper extremely low-intensity ultrasonic courtship songs close to females. Since low sound levels will prevent eavesdropping by predators, parasites and conspecific rivals, we predicted low intensity ultrasound communication to be widespread among moths. Here we tested 13 species of moths including members of the Noctuidae, Arctiidae, Geometridae and Crambidae. Males of nine species, 70%, produced broadband ultrasound close to females. Peak frequencies ranged from 38 to above 100kHz. All sounds were of low intensity, 43-76dBSPL at 1cm [64±10dBpeSPL (mean ± s.d.), N9 species]. These quiet and/or hyper-frequency ultrasounds are audible to nearby mates, but inaudible to unintended receivers. Although largely unknown because it is so inconspicuous, acoustic communication using low intensity ultrasound appears to be widespread among hearing moths. Thus, acoustic communication may be the norm rather than the exception. Supplementary material available online at

“…The result obtained here indicated that the 2-component mixture acts as a single, comp~Ln_ent~ However, Kawasaki (1981) observed a behavioral change in males when compound A was added into the air stream of a mixture of compounds A and B, and concluded that compound A is the main component which induces males to locate the position of the lure source emitting the sex pheromone, a mixture of compounds A and B. In addition to this, some males were captured in a trap baited with compound A in the field (Yushima et al 1974). These results seem to depend on the capacity of compound A to induce male orientation flight (Fig.…”

“…Its sex pheromone was identified as a mixture of (Z,E)-9, ll-tetradecadienyl acetate (Compound A) and (Z,E)-9, 12-tetradecadienyl acetate (Compound B) and the blend ratio of compounds A and B in extracts of females is 9:1 (Tamaki et al 1973). Mixtures of these chemicals ranging from 8:2 to 39:1 showed equally high attractiveness in a field trapping test (Yushima et al 1974).…”

-Behavioral responses of male Spodoptera litura to the female sex pheromone components, (Z, E)-9, ll-tetradecadienyl acetate (compound A) and (Z, E)-9, 12-tetradecadienyl acetate (compound B), and mixtures of compounds A and B were analyzed in the laboratory. Male orientation flight in a wind tunnel was induced by a lure dispenser onto which 1.1xl0-3ng of a mixture (A:B=10:I) was absorbed, while lng of compound A was required to induce the same level of behavior. The blend ratio was important for trap catch and orientation flight of males and a 10:1 mixture of compounds A and B whs most effective. A mixture (10:1) was more effective than compound A alone in induction of movement, walking, and flying in resting males in a glass tube. These results indicated that 2 sex pheromone components act as a set from the initial to final steps of male attraction to female.
