“…We predicted the latter case only in cases where males remained stationary until a plume reached them. Given that even the simplest of plume models-which lack much known detail (Vickers 2000;Cardé and Willis 2008;Riffell et al 2008)-could produce such a diverse set of outcomes when male behavior alone was varied, it appears robust to caution against any expectations of greatly increased arrival rates with increases of pheromone output.…”

“…Signaling effort may in some cases refer to the duration of calling, usually measured as earlier onset of calling, resulting in a longer period of calling each night (e.g., Delisle and McNeil 1987;Gemeno and Haynes 2000). An increase in pheromone concentration is an alternative mechanism to increase signaling effort (e.g., Foster et al 1995), assuming that pheromonal cues are not at such high concentrations that they swamp male sensory receptors and arrest response; Baker and Haynes 1989;Vickers 2000).…”

“…However, supporting the view that the matter is likely to be complex (appendix), studies of male responses to varying concentrations of synthetic pheromones indicate a nonlinear pattern. Typically, male numbers increase up to a certain concentration but with no additional increase-and sometimes a reduction-at higher concentrations (Baker et al 1985;MafraNeto and Cardé 1995;Vickers 2000). While single moths might not be capable of producing such high concentrations, multiple females signaling in close proximity to each other could create a similar, cumulative effect.…”

Although females rarely experience strong mate limitation, delays or lifelong problems of mate acquisition are detrimental to female fitness. In systems where males search for females via pheromone plumes, it is often difficult to assess whether female signaling is costly. Direct costs include the energetics of pheromone production and attention from unwanted eavesdroppers, such as parasites, parasitoids, and predators. Suboptimal outcomes are also possible from too many or too few mating events or near-simultaneous arrival of males who make unwanted mating attempts (even if successfully thwarted). We show that, in theory, even small costs can lead to a scenario where young females signal less intensely (lower pheromone concentration and/or shorter time spent signaling) and increase signaling effort only as they age and gather evidence (while still virgin) on whether sperm limitation threatens their reproductive success. Our synthesis of the empirical data available on Lepidoptera supports this prediction for one frequently reported component of signalingtime spent calling (often reported as the time of onset of calling at night)-but not for another, pheromone titer. This difference is explicable under the plausible but currently untested assumption that signaling earlier than other females each night is a more reliable way of increasing the probability of acquiring at least one mate than producing a more concentrated pheromone plume.

“…Ovulated females may use casting as a behavior to ensure that they do not overshoot the spawning grounds and bypass possible mates. It is notable that when ovulated females lose the 3kPZS signal, it takes several seconds (many sniffs) to begin casting, suggesting that either there is a significant integration time to recognize that the signal has been lost, or that upstream movement, once triggered by the pheromone, continues for a period governed by an internal mechanism, as proposed for moths (22). Sea lamprey and moths appear to use similar casting strategies, albeit on different temporal and spatial scales, to relocate lost plumes.…”

Female insect pheromone blends induce robust tracking responses in males and direct them into traps. In vertebrates, pheromones that induce strong and precise tracking responses in natural habitats have rarely been described. Here, we show in the sea lamprey (Petromyzon marinus), a vertebrate invader of the Laurential Great Lakes, that a synthesized component of the male mating pheromone, 7␣, 12␣, 24-trihydroxy-5␣-cholan-3-one 24-sulfate (3kPZS), when released into a stream to reach concentrations of 10 ؊14 , 10 ؊13 , 10 ؊12 ,10 ؊11 , or 10 ؊10 M, triggers robust upstream movement in ovulated females drawing Ϸ50% into baited traps. Experiments conducted in diverse stream segments demonstrate the level of behavioral response was not affected by habitat conditions and is effective over hundreds of meters. 3kPZS is equally effective at luring ovulated females as the whole pheromone blend released by males between 10 ؊14 and 10 ؊11 M. 3kPZS diverts ovulated females away from and disrupts orientation to male washings when applied at concentrations higher than washings. Indeed, a single pheromone compound is able to redirect female sea lampreys away from a natural pheromone source and lure them into traps, which should be more effective than targeting males when applied in population control. Our findings may spur the discovery of other potent and environmentally benign agents to combat biological invasion, a process accelerated by globalization, exacerbated by climate change, and costing the global economy US$ 1.4 trillion of damage annually.invasive species ͉ odorant tracking ͉ pest control ͉ odorant disruption ͉ jawless vertebrate

“…7e was observed to move circuitously across the center of the arena and then enter the HS which is reminiscent of paths associated with the use of a beacon (Geva-Sagiv et al 2015). This individual performed what appears to be a type of spiral search similar to olfactory-guided behavior observed in other animals (Vickers 2000;Calhoun et al 2014;Svensson et al 2014). The behavior of this subject, however, was not expressed by other individuals.…”
