“…2). Similar to many dacine species (Barton Browne, 1957; Fay & Meats, 1983; Mazomenos, 1989), monandry appears to be the norm in B. cacuminata , with mated females being less receptive to subsequent copulation attempts, a fact borne out by the paucity of mating behaviour in MM flies (Fig. 4).…”

“…Experimental flies were from a stock laboratory colony maintained at Griffith University, which is refreshed every 3–4 generations with wild flies in approximately a 1 : 1 ratio. Bactrocera cacuminata adults take 10–12 days to attain sexual maturity and mate soon after: males are polygamous, females are monandrous (Barton Browne, 1957; Fay & Meats, 1983; Mazomenos, 1989). Mating is restricted to dusk.…”

Abstract. Resource use in adult Dacinae (Diptera: Tephritidae) is believed to be restricted to the host plant (i.e. the plant that provides fruit for oviposition and larval development). However, studies on Bactrocera cacuminata did not support this hypothesis. Thus, it was hypothesized that adult flies partition their diurnal activities between spatially separated resources (host plant, sugar, protein and methyl eugenol) as a function of the physiological status of the fly (immature, mature–unmated, mature–mated). In accordance with a priori predictions, the results of a field‐cage study show that there are significant diurnal patterns in abundance and behaviour, and that flies of different physiological status use resources differently. Immature flies spend most of their time foraging for sugar and protein to facilitate development. Sexually mature flies forage for sugars during the day, and at dusk, responded strongly to methyl eugenol and mate. The fact that polygynous males wait at methyl eugenol at dusk whereas the mated, monandrous females spend their time ovipositing in fruit and are nonresponsive to methyl eugenol, supports Metcalf's hypothesis that such phenylpropanoids serve as mate rendezvous cues.

“…Os resultados obtidos nessa pesquisa concordaram com aqueles observados na literatura em relação à infl uência da temperatura no número de cópulas de insetos, o qual pode aumentar (Cook 1994, Kindle et al 2006) ou diminuir (Fay & Meats 1983) com a elevação térmica. Assim, apesar de não ter havido correlação entre o número de cópulas e os parâmetros biológicos observados, para S. frugiperda, mantida a 25ºC, o maior número de cópulas implicou em aumento da fecundidade, concordando com dados presentes na literatura (revisado por Arnqvist & Nilsson 2000).…”

Neotropical Entomology 37(5): 528-535 (2008) Temperature Effects on the Mating Frequency of Anticarsia gemmatalis Hüebner and Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae)ABSTRACT -This paper deals with the infl uence of temperature on the mating frequency of two lepidopterans, Anticarsia gemmatalis Hübner and Spodoptera frugiperda (J.E. Smith), which use different strategies of allocation, and with the utilization of nutrients for their reproductive activities. The insects were reared on artifi cial diets at 25ºC, and the adults were exposed to fi ve temperatures (15, 20, 25, 30, and 35ºC) to observe the infl uence of each temperature on their mating frequency, fecundity, fertility and longevity. The temperature affectedthe mating frequency of both species, being more evident at 15ºC and 35ºC, mainly for A. gemmatalis, which presented a drastic reduction on mating activities. The highest number of matings were observed from 20ºC to 30ºC, with S. frugiperda presenting mating activity (0-8) much higher than that of A. gemmatalis (0-2), but no correlation was observed among the number of matings and all other biological parameters evaluated (fecundity, fertility and longevity). However, S. frugiperda showed a positive correlation between fecundity and mating activity of females (r = 0.589; P = 0.003) at 25ºC. The highest fecundities were observed at temperatures from 20ºC to 30ºC for S. frugiperda and at 25ºC for A. gemmatalis. For both species, the longevity of males and females decreased as temperature increased.KEY WORDS: Reproduction, defoliator caterpillar, spermatophore, fecundity RESUMO -Este trabalho estudou a infl uência da temperatura na freqüência de cópula de Anticarsia gemmatalis Hübner e Spodoptera frugiperda J. E. Smith, que empregam diferentes estratégias de alocação, e a utilização de nutrientes para suas atividades reprodutivas. Os insetos foram criados em dieta artifi cial a 25ºC, sendo a infl uência da temperatura na freqüência de cópula, fecundidade, fertilidade e longevidade de adultos avaliada em cinco temperaturas (15, 20, 25, 30 e 35ºC). A temperatura afetou a freqüência de cópula de ambas as espécies, sendo o seu efeito mais evidente nas temperaturas extremas estudadas (15ºC e 35ºC), principalmente, para A. gemmatalis, que apresentou redução drástica em sua atividade de cópula. Temperaturas intermediárias (20ºC a 30ºC) permitiram o maior número de cópulas, com S. frugiperda apresentando (até oito cópulas) atividade de cópula muito superior à de A. gemmatalis (até duas cópulas). Mesmo com a variação encontrada na atividade de cópula nas diferentes temperaturas, não foi verifi cada correlação entre o número de cópulas e os demais parâmetros biológicos observados (fecundidade, fertilidade e longevidade), com exceção da fecundidade de S. frugiperda a 25ºC, que apresentou correlação positiva com a atividade de cópula nessa temperatura (r = 0,589; P = 0,003), indicando que as alterações na atividade reprodutiva desse inseto foram decorrentes, basicamente, de sua resposta à tem...

“…There is therefore the possibility of the difference between cue‐lure and non cue‐lure treatments being confounded with differences in age. However, the mean differences in the age of flies used in the two categories was only 4 d and it is known that other activities, such as mating propensity, stay practically constant for at least 6–8 weeks ( Fay & Meats 1983).…”

Summary Movements of mature male Bactrocera tryoni (Froggatt) (Diptera: Tephritidae) were observed individually in a wind tunnel under conditions of ‘cue‐lure with wind’, ‘cue‐lure with no wind’, ‘wind only’ and ‘no wind or cue‐lure’. Further observations were made using a dense foliage array in the wind tunnel and a structured plume of cue‐lure. Patterns of walking or flying were essentially the same in all of the first four treatments except that in the ‘cue‐lure with wind’ treatment, over half of the flies moved in a consistent track upwind for at least 400 mm at some time during the first 5 min of observation. With clean wind, only 10% of the flies did this. The result was that mean net upwind displacement after 5 min in the ‘cue‐lure with wind’ treatment significantly exceeded that in the other three treatments, the results of which did not differ significantly from each other. The upwind tracks were accomplished by either walking or flying (with or without stops) or by a combination of both. When the wind tunnel was filled with a dense foliage array, the results with cue‐lure laden wind were similar to those obtained with the equivalent treatment without foliage, except that upwind tracks were predominantly in short stages. When flies were exposed to a structured plume of cue‐lure odour (without foliage present), they did not apparently alter their behaviour on leaving or entering the plume, but some did make consistent upwind tracks while they were in the plume.
