“…Females of the arctiid moth U. ornatrix form aggregations of calling individuals and adults of both sexes are attracted to the pheromone source in a dose‐dependent manner, thus as a large chorus will attract more receptive males, individual females could increase their probability of mating by joining other calling females (Lim & Greenfield, , ). Pseudaletia adultera females do not start calling for several days post‐emergence, a trait that has been associated with migratory species (McNeil, ).…”

“…As most of the noctuid species exhibiting female autodetection are considered migrants, it is possible that females of migratory species, when arriving in a new habitat where the density of males is unknown, use a form of chorusing as a strategy to attract males to a site with a high concentration of pheromones. However, if this is a strategy used, there may still be female‐female competition for certain positions within the chorus, as this would influence access to approaching males, as noted in the case of U. ornatrix (Lim & Greenfield, , ).…”

Changes in female calling behavior in response to the presence of conspecific pheromones (pheromone autodetection) have been demonstrated in a number of moth species. However, the observed changes vary between species, and several ecological and adaptive explanations for autodetection have been proposed. We studied the effect of conspecific females on the calling behavior of the noctuid moth Pseudaletia adultera (Schaus) (Lepidoptera: Noctuidae, Hadenini), by comparing the age of first calling, as well as the onset and pattern of calling, when females were held individually or in the presence of conspecifics. Grouped females started calling at a lower age, a higher percentage of females called during the scotophase, and they called longer compared to females held in isolation. We also demonstrated that female antennae respond to each of the three main components of the sex pheromone – (Z)‐11‐hexadecen‐1‐ol, (Z)‐11‐hexadecen‐1‐yl acetate, and (Z)‐11‐hexadecenal – and that the response patterns differed from those of male antennae. By calling more and extending her calling window in presence of conspecific females, a female may increase her chances of accessing males. However, the potential benefits need to be considered within an ecological context, considering factors such as migration, oviposition, and foraging.

“…Note that the competition for mates definition used here contrasts with that of recent reviews that dilute the concept of sexual selection on females to include any sort of social competition to reproduce (Clutton-Brock, 2007Shuker, 2010). This is either a form of passive attraction (Arak, 1988) of males to the most prominent signal of a group of non-interacting females (the usual case in moths; Lim & Greenfield, 2008) or a more active form of choice of certain females by males (probably more likely when females increase signalling effort in response to nearby competitorse.g., the arctiid moth Utetheisa ornatrix L., in which females appear to be competing for nutritious male spermatophores; Lim & Greenfield, 2007). Most of the hypotheses can be related to some form of sexual selection on females.…”

“…There was some evidence of male mate choice and also of signal interference between females; attractive pheromones from certain (e.g., large) females appear to interfere with the ability of other individuals to attract males (Rhainds et al, 1999). This is either a form of passive attraction (Arak, 1988) of males to the most prominent signal of a group of non-interacting females (the usual case in moths; Lim & Greenfield, 2008) or a more active form of choice of certain females by males (probably more likely when females increase signalling effort in response to nearby competitorse.g., the arctiid moth Utetheisa ornatrix L., in which females appear to be competing for nutritious male spermatophores; Lim & Greenfield, 2007). Importantly, however, even passive attraction still imposes sexual selection on females for certain traits such as body size.…”

Mating failures as a consequence of sexual selection on females

Multiple mating by individuals successful in sexual competition results in other individuals failing to mate. This leads to sexual selection within a sex, typically the males. However, more species are coming to light in which females are subject to sexual selection. We review the contexts for and nature of sexual selection on females in several insect species where female mating failures have been noted. We then examine evidence of mating failures in two groups of insects, empidid flies (Diptera) and tettigoniid Orthoptera (katydids), in which sexual selection is expected to be relatively stronger on females. Using data from the field, we show for two species of katydids that, as predicted, there are mating failures by females in populations in which the direction of sexual selection appears to be reversed, but not in populations where sexual selection appears to be stronger on males.

“…Many female moths can perceive their own pheromone as well as pheromone compounds of other species (e.g., Ljungberg et al 1993; Schneider et al 1998; Groot et al 2005b; Hillier et al 2006). Also, most female moths produce their sex pheromone de novo every night (e.g., Raina 1989; Rafaeli 2002; Jurenka 2003), and can modulate the time and temporal patterning of pheromone release (calling) in relation to environmental conditions (Schal and Cardé 1985; Lim et al 2007) and presence of conspecifics (Conner et al 1980; Lim and Greenfield 2007, 2008). Hence, it may be possible that females can vary their biosynthesized as well as emitted pheromone blend to some extent depending on the prevailing olfactory cues in their habitat.…”

Geographic and Temporal Variation in Moth Chemical Communication

In moth pheromone communication signals, both quantitative and qualitative intraspecific differences have been found across geographic regions. Such variation has generally been hypothesized to be due to selection, but evidence of genetic control of these differences is largely lacking. To explore the patterns of variation in pheromone signals, we quantified variation in the female sex pheromone blend and male responses of two closely related noctuid moth species in five different geographic regions for 2-3 consecutive years. We found significant variation in the ratios of sex pheromone blend components as well as in male response, not only between geographic regions but also within a region between consecutive years. The temporal variation was of a similar magnitude as the geographic variation. As far as we know, this is the first study reporting such temporal variation in moth chemical communication systems. The geographic variation seems to at least partly be controlled by genetic factors, and to be correlated with the quality of the local chemical environment. However, the pattern of temporal variation within populations suggests that optimization of the pheromonal signal also may be driven by within-generation physiological adjustments by the moths in response to their experience of the local chemical environment. Kirkpatrick and Ravigne 2002). However, the evolution of behavioral isolation is poorly understood (Coyne and Orr 2004). To gain insight into the evolution of prezygotic behavioral isolation it is essential to quantify intraspecific variation in the premating signals, on which selection may operate, and biotic and abiotic factors that contribute to this variation.Premating signals are generally hypothesized to be under stabilizing selection
