Reduction in responsiveness of males of Epiphyas postvittana (Lepidoptera) to sex pheromone following previous brief pheromonal exposure

Argentine Ant Trail Pheromone Disruption is Mediated by Trail Concentration

“…Thus, it is possible that disruption could work by effectively widening a trail so that its boundaries with clean air are not encountered. Alternatively, sensory overload by prolonged adaptation to pheromone has been put forward as an explanation for the mechanism of disruption in a number of species of moths, including, Epiphyas postvittana (Bartell and Lawrence, 1973) and Oriental fruit moth, Cydia (=Grapholitha molesta) (Rumbo and Vickers, 1997), and thus, it is possible that the increased concentration of trail pheromone in the air could cause sensory adaption in the trail-pheromone ants. Falsetrail following, in which search effort is expended unsuccessfully, is another mechanism proposed for mating disruption in moths (Bartell, 1982).…”

Evidence that mass trapping suppresses pink bollworm populations in cotton fields

“…Adaptation of the sensory input due to continuous stimulation with high concentration of pheromone has been correlated to inflight arrestment followed by termination of pheromone-related behavior (Baker et al, 1989). Furthermore, males of several species of moths when exposed to pheromone are able to respond to subsequent exposures of higher concentrations, but not to exposures of the same or lower concentrations (Shorey et al, 1967;Traynier, 1970;Bartell & Lawrence, 1973;Kuenen & Baker, 1982;Figueiredo & Baker, 1992). Thus interception of high concentration pheromone plumes from the oil traps may hinder subsequent responses of the male to less concentrated pheromone plumes, such as those emitted by calling females, due to central nervous system habituation and/or sensory adaptation.…”

“…Furthermore, males of several species of moths when exposed to pheromone are able to respond to subsequent exposures of higher concentrations, but not to exposures of the same or lower concentrations (Shorey et al, 1967;Traynier, 1970;Bartell & Lawrence, 1973;Kuenen & Baker, 1982;Figueiredo & Baker, 1992). The depression of behavioral activity following pre-exposure to pheromone may last from a few hours to a few days (Shorey et al, 1967;Traynier, 1970;Bartell & Lawrence, 1973;Kuenen & Baker, 1981;Figueiredo & Baker, 1992). The depression of behavioral activity following pre-exposure to pheromone may last from a few hours to a few days (Shorey et al, 1967;Traynier, 1970;Bartell & Lawrence, 1973;Kuenen & Baker, 1981;Figueiredo & Baker, 1992).…”

Reduction in responsiveness of male apple moths, Epiphyas postvittana, to sex pheromone following pulsed pheromonal exposure

“…Previous work with Epiphyas showed that the degree of reduction in responsiveness increased with increasing duration of preexposure (Bartell & Lawrence, 1973), and with increasing concentration (Bartell & Lawrence, 1976), findings which indicate that the amount by which responsiveness decreased was directly related to the total amount of sensory input elicited during the pre-exposure. This, coupled with the near certainty that adaptation occurs during prolonged exposure, suggests that pulsed pre-exposure should result in a greater degree of reduction in subsequent responsiveness than would the same dosage applied continuously.…”

“…Bartell & Lawrence (1973) concluded that the prolonged reduction in males of the light-brown apple moth, Epiphyas postvittana (Walk. ), could probably be attributed to changes induced in the central nervous system by sensory input elicited by the pheromone during preexposure.…”
