“…However, other studies have shown that the lights-off signal is the cue responsible for setting the diel timing of calling in Mamestra species. (Subchev, 1983;Howlader & Gerber, 1986a). In conclusion, the Dutch and Bulgarian populations ofM.…”

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.

“…Portanto, a glândula não era evertida. A protrusão total dos segmentos abdominais foi freqüentemente acompanhada da elevação do abdome, da extensão do ovipositor expondo a membrana intersegmentar e da protrusão da glândula de feromônio (West et al 1984, Howlader & Gerber 1986.…”

“…Algumas vezes permaneciam no mesmo local, outras vezes moviam-se pela gaiola, pousando em locais diferentes antes de voltar a exibir o comportamento de chamamento. Esses resultados estão em concordância com o padrão de chamamento observados nos noctuídeos Euxoa declarata Walker (Teal & Byers 1980) e Mamestra configurata Walker (Howlader & Gerber 1986). No padrão de liberação de feromônio contínuo, a taxa de liberação é provavelmente mais baixa quando comparada com aquelas em que o padrão de liberação é discreto, pois durante os períodos curtos seriam liberadas concentrações maiores de feromônio (Turgeon & Mcneil 1982).…”

-This work was carried out to determine and compare the effects of three diets (Psidium guajava and Eucalyptus grandis host-plant leaves and artificial diet) on the calling behavior and on the temporal pattern of calling behavior of Thyrinteina arnobia (Stoll). All activities of virgin females during six scotophases were observed in the laboratory at 5min. intervals until the females stopped calling in the following photophase, at 22 ± 1 o C, 70 ± 5% RH and 10h scotophase. The diets affected the calling behavior of T. arnobia. Two positions of calling were observed. Calling of female virgins started in the first hour immediately after emergence. The calling pattern was characteristic of the continuous pattern. The type of diet affected the mean onset of calling time (pre-calling) and the total time calling of T. arnobia. Older females called earlier than younger after the onset of scotophase. The diets affected the color of pheromone gland.KEY WORDS: Insecta, Eucalyptus brown looper, guava, defoliator RESUMO -Este estudo teve como objetivos determinar e comparar o efeito de três dietas: Psidium guajava, Eucalyptus grandis e dieta artificial no comportamento de chamamento e no padrão temporal do comportamento de chamamento de fêmeas virgens de Thyrinteina arnobia (Stoll). Foram analisados os parâmetros: tempo médio para o início do chamamento, número médio de chamamento, tempo médio de cada chamamento e tempo médio total de chamamento. Os bioensaios relacionados ao comportamento de chamamento de fêmeas virgens foram realizados durante seis escotofases consecutivas e as observações tomadas a cada 5 min., a 22 ± 1 o C, 70 ± 5% de UR e 10h de escotofase. As fêmeas, independente da dieta analisada, apresentaram duas posições diferentes de chamamento. A maioria das fêmeas virgens iniciou o chamamento na 1 a hora da 1 a escotofase. O padrão de chamamento da fêmea individualizada foi característico de um padrão contínuo. O tipo de dieta oferecida na fase larval influenciou o início do comportamento de chamamento (pré-chamamento) e o tempo médio total de chamamento. O tipo de dieta também alterou a coloração da glândula de feromônio.

“…The extension of the ovipositor to expose the cuticle overlying the pheromone glands is the main characteristic of the calling posture, as in other lepidopterans (Turgeon and McNeil 1982;West et al 1984;Howlader and Gerber 1986).…”

“…However, females of many moth species are not always reproductively mature or capable of calling immediately after emergence. For example, females of Mamestra conWgurata (Lepidoptera: Noctuidae) (Howlader and Gerber 1986) and Copitarsia consueta (Lepidoptera: Noctuidae) (Rojas and Cibrián-Tovar 1994) call for the Wrst time during the second or third scotophase after emergence.…”

Calling behaviour and male response towards sex pheromone of poplar moth Condylorrhiza vestigialis (Lepidoptera: Crambidae)

et al. 2008

The calling behaviour of virgin females Condylorrhiza vestigialis Guenée, 1854 (Lepidoptera: Crambidae) and the female pheromone gland extract activity were studied under laboratory conditions. Most of the females started calling from their Wrst scotophase period after emergence. Maximum calling occurred between the seventh and tenth hours of the scotophase period. The length of the calling increased with age until the fourth scotophase, but the onset of calling time did not diVer with age. The number of calling bouts increased signiWcantly with age, but the mean duration of each calling bout (20.8 min) did not vary with age. Extracts of pheromone glands evaluated in a Y-tube olfactometer attracted signiWcantly more males than control, 70 and 30%, respectively. Gas chromatographic-electroantennogram detection (GC-EAD) analysis of these extracts indicated the presence of a single EAD-active peak, the putative sex pheromone of the species. This pheromone compound may be suitable for monitoring populations densities of C. vestigialis, and for detection of the onset of the seasonal Xight period. An eYcient pheromone is of importance also with respect to current attempts to develop new control methods for this important pest of Populus spp. in Brazil.
