“…brassicae is also similar to that of related Mamestra species. Mamestra brassicae shows changes in calling behaviour with increasing age similar to those in M. configurata Walker (Howlader & Gerber, 1986b). In this species also, the onset of calling advances in time with decreasing length of scotophase (Gerber & Howlader, 1987).…”

Die periodicity of calling and the effect of age and photoperiod on calling behaviour were studied in virgin females of the cabbage moth, mamestra brassicae L. (Lepidoptera: Noctuidae). No calling activity was observed during the first scotophase. Most females called for the first time during the 2nd or 3rd scotophase after emergence, regardless of the photoperiod. Moths maintained under 16L : 8D started calling significantly later in the scotophase than those maintained under 18L : 6D. With increasing age, moths initiated calling significantly earlier. Under the 16L : 8D photoregime, the mean onset calling time decreased from scotophases 2 to 3, after which it stabilized around ca. 260 min after the start of the scotophase. With 18L : 6D, the onset of calling decreased until scotophase 4, and subsequently stabilized around ca. 130 min after lights off.

“…Some features of the calling and courtship behavior in P. citrella females, particularly wing movements, were previously observed in Lymantria dispar (L.) (Charlton & Cardé 1990), Mamestra configurata Walker (Howlander & Gerber 1986), and Bucculatrix thurberiella Busck (Lingren et al 1980). Male wings overlapping over female wings during copulation have been previously observed in B. thurberiella (Lingren et al 1980).…”

Bases Comportamentais para a Identificação e Síntese do Feromônio Sexual do Minador-dos Citros,Phyllocnistis citrella Stainton (Lepidoptera: Gracillariidae)RESUMO -O objetivo desta pesquisa foi caracterizar o comportamento sexual do minador-doscitros, Phyllocnistis citrella Stainton, como suporte para o isolamento, identificação e síntese do seu feromônio sexual. O acasalamento de P. citrella ocorre no intervalo entre 1h antes do início da fotofase e 1h após o término da escotofase, entre adultos de um e dois dias de idade. O comportamento de corte e cópula foi descrito para essa espécie, sendo a duração média da cópula de 49,6 min. Estudos conduzidos em olfatômetro tipo Y demonstraram que os machos foram fortemente atraídos pelas fêmeas virgens bem como pelo extrato natural de glândulas de feromônio sexual das fêmeas. PALAVRAS-CHAVE:Comportamento sexual, comportamento de corte e cópula, olfatômetro tipo Y ABSTRACT -The objective of this work was to characterize the sexual behavior of the citrus leafminer, Phyllocnistis citrella Stainton, as the foundation for the isolation, identification, and synthesis of the complete sex pheromone of this species. Mating occurred in a time window of 2h, starting 1h before the onset of photophase. The large majority of tested insects mated in the first two days after emergence, with no significant difference between mating at day 1 and day 2. A stereotypical courtship and copulation behavior were described for this species. When mating was successful, the copulation was recorded in average for 49.6 min. In Y-olfactometer tests conducted at the time of mating activity, males were strongly attracted to caged virgin females as well as to extracts from putative pheromone glands.

“…Others report the proportion of females calling (Hendrikse 1979) or how early calling begins each night (Delisle and McNeil 1987;Kou and Chow 1987;Delisle 1992). Several studies report changes in calling bout number and bout length (Howlader and Gerber 1986;Jacas and Peña 2002;Mazor and Dunkelblum 2005;Ming et al 2007), with calling bout defined as a period of time over which a female is observed in the characteristic position of raising her abdomen and periodically everting her ovipositor.…”

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.
