“…There is a paucity of studies on the effects of temperature on pheromone production and expression in animals, though examples of the lack of temperature effects on pheromone production can be found (e.g., Pandey and Pandey 1990). Certain insects exhibit pheromone-releasing behaviors that increase in frequency with increasing temperature, leading to periodicity in pheromone release that can be both circadian and seasonally controlled (e.g., Sower et al 1971;Pope et al 1982). In all vertebrates studied to date with described or putative pheromones, pheromone production and expression are thought to be controlled almost exclusively by hormones (e.g., amphibians, Yamamoto et al 1996;Iwata et al 2000a;Kikuyama et al 2005;reptiles, Mendonça and Crews 1996;birds, Rajchard 2007;rodents, Bruce 1965;Thiessen et al 1968;Mugford and Nowell 1971;primates, Michael 1975;goats, Iwata et al 2000b).…”

Low Temperature Dormancy Affects the Quantity and Quality of the Female Sexual Attractiveness Pheromone in Red-sided Garter Snakes

Low temperature dormancy is a necessary requirement of the annual cycle of most nonmigratory, temperate vertebrates. The red-sided garter snake, Thamnophis sirtalis parietalis, overwinters in communal dens during its prolonged winter dormancy (8 mo), and upon emergence, reproductive behavior of both sexes is maximal. Previous work on this species showed that male courtship behavior is maximally induced after simulated low temperature dormancy. The purpose of this study was to determine whether low temperature dormancy affects the pheromone profiles of individual female red-sided garter snakes. We collected females in the fall at den sites in Manitoba, Canada, and extracted pheromones from individuals at three different time points: fall (field), winter (lab), and spring (lab). Total skin lipid and pheromone fraction masses increased from fall to spring, and pheromone profiles were distinctly different in the fall and spring. Pheromone profiles became dominated by the long-chain, unsaturated methyl ketone components of the blend by the time snakes emerged in the spring. Further, the amounts of both saturated and unsaturated components increased from fall to spring, suggesting significant sex pheromone synthesis was induced by low temperature dormancy.

“…In addition, in many moths, the maximal pheromone titer in female glands is found at the onset of peak calling activity (Shorey & Gaston, 1965;Fatzinger, 1973;Pope et al, 1982;Raina et al, 1986;Delisle & Royer, 1994). In some species, such as Helicoverpa zea (Boddie) (Lepidoptera: Noctuidae), pheromone titers increase up to the onset of calling activity , whereas in other moths, such as Trichoplusia ni (Hübner) (Noctuidae), pheromone production is continuous and a high titer is maintained in the gland until the beginning of calling activity (Sower et al, 1971;Hunt & Haynes, 1990). In this context, the period of mating activity and particularly the onset of it, three hours after emergence, should be considered as the best time for collecting pheromone from emerging females of P. archon.…”

“…Sexual activity was recorded mainly between 11:00 h and 15:00 h and studies on reproductive behaviour should focus on this period. Nevertheless, daily activity rhythms in insects may be influenced by many factors, particularly temperature and photoperiod (Danilevsky et al, 1970, Sower et al, 1971. During the flight season of P. archon, which is from May to September, photoperiod and temperature vary.…”

“…Indeed, in most Lepidoptera, mating activity is regulated by females releasing a pheromone during specific calling windows (Callahan, 1958;Shorey & Gaston, 1965;Sower et al, 1971). The beginning of calling generally coincides with maximum production of the pheromone by females in Lepidoptera (Fatzinger, 1973;Coffelt et al, 1978;Raina et al, 1986;review in Delisle & Royer, 1994) and is the first step in reproductive behaviour.…”

Abstract. Paysandisia archon (Burmeister, 1980) (Lepidoptera: Castniidae) is an accidentally introduced pest that damages palm trees in the northern Mediterranean area. To our knowledge, there are no experimental studies on its mating behaviour, and little is known about its biology and ecology. In the present study, we used outdoor experiments to investigate several characteristics of the reproductive behaviour of P. archon: sexual maturity, diel periodicity of mating, occurrence of polyandry and delay between mating and laying eggs. The results indicate that 73% of the individuals studied were sexually mature three hours after adult emergence. Mating peaked between 14:00 h and 15:00 h and 87% of the females were fertilized and started laying eggs 1.25 (± 1.14) days after mating. Females were generally monandrous, but nevertheless remained attractive after mating. The results of this study provide the necessary background knowledge for studying several aspects of P. archon reproductive biology, in particular oviposition, sex pheromones and their role in mediating mating behaviour in this pest. These results are the first step in developing tools for monitoring populations of this pest.

“…It is known in other Lepidoptera that ambient temperature can modify the rhythms of female calling, or male response, or both, as has been shown in an arctiid (Card6 1971;Card6 and RoeIofs 1973), numerous tortricids (Comeau 1971;Sanders and Lucuik 1972), and a noctuid (Sower et al 1971 ). In these cases mating rhythms on cool summer or spring days occur earlier than those at warm summer temperatures, such that the period of activity is shifted forward to the warmer afternoon or early evening.…”

Diel Periodicity of Male Sex Pheromone Response and Female Attractiveness in the Gypsy Moth (Lepidoptera: Lymantriidae)

1974

Can. Ent. 106: 479484 (1974) In field studies gypsy moth males were attracted to synthetic cis-7,s-epoxy-2-methyloctadecane (disparlure), the female sex pheromone, and virgin females from 0900 to 2000 (Eastern Standard Time). The greatest numbers of males were lured to the synthetic attractant or the calling female from 1100 to 1500. These periods of male response are longer than reported in previous (1896 and 1932) New England investigations and suggest the possible recent evolution of a new die1 rhythm of male sex pheromone response. IntroductionAlthough there have been many investigations of the pheromonal biology of the gypsy moth, Portherria dispar (L.), the rhythms of male attraction to the female sex pheromone and the calling female have not been studied in detail. This paper describes the periodicity of male attraction to cis-7,8-epoxy-2-methyloctadecane (disparlure), the sex pheromone of the female gypsy moth (Bier1 et al. 1970), and the periods during which the female attracts males.
