“…This observation is complemented by the finding by Duyck and his co-workers (Duyck et al, 2010) that the lifespan of males in a medfly sister species, the natal fruit fly ( C. rosa ), is also much greater than that of females. These findings are important because the general consensus in much of the gerontology literature is that females of most species live longer than males (Austad, 2006).…”

“…Whereas the life expectancy at eclosion for the medfly in most studies is typically around 50 to 70 days, (e.g. Carey et al, 2002; Carey et al, 2008), Duyck and his co-workers (Duyck et al, 2010) reported that life expectancies of male and female C. rosa were 160 and 143 days, respectively, with lifespans approaching one year (females=328 days; males= 357 days). Given the similarities in the life histories of C. rosa and C. capitata but the 2–3 fold difference in their adult lifespans, it is clear that the factors that select for extended longevity go beyond the basic dichotomy used by Diamanditis and his co-workers (Diamantidis et al, 2009) to classify shorter- and longer-lived medfly biotypes.…”

The purpose of this paper is to summarize recent research on longevity, aging and adaptation in wild medfly populations and in a close relative of the medfly. The key findings include a new life table identity that relates age structure and the distribution of deaths in stationary populations, seasonal variation in the post-capture longevity of trapped medflies of unknown age, greater longevity of once-wild (wild-caught) adult medflies relative to never-wild (laboratory-emerged) individuals, differences in age specificity of different medfly field capture methods, large variation in the sex-specific longevity of six medfly global biotypes (e.g. Kenya; Brazil; Greece), and the extraordinary longevity of the natal fruit fly-a sister species of the medfly. The Discussion contains a listing of discoveries derived from this recent research that appear to be unique to the investigations on medfly aging in the wild. It is suggested that studies of aging in wild populations of Drosophila melanogaster have the potential to exploit this model organism in an entirely new aging research domain and thus complement the already deep literature on aging in this species.

“…However, the generalist species C. capitata lived as long as other specialists. Moreover, with an average lifespan of 140 days, the generalist species C. rosa 36 would sit between C. cosyra and C. scaevolae, giving more support to the fact that lifespan in this genus may not be determined by host specialisation. Confirming these observations, when regressions corrected by phylogeny were used, the number of hosts did not affect average lifespan, maximum lifespan or the coefficient of variation.…”

“…Musca domestica 34 ), the species investigated here lived two to five-fold longer. Among tephritid species there have been other reports of extremely long lives, with lifespans of up to 431 and 357 days for Anastrepha alveata and Ceratitis rosa respectively 35,36 . Apart from host range, little is known about the biology of many species used in this study.…”

Exploring the role of host specialisation and oxidative stress in interspecific lifespan variation in subtropical tephritid flies

in herbivorous insects, the degree of host specialisation may be one ecological factor that shapes lifespan. Because host specialists can only exploit a limited number of plants, their lifecycle should be synchronised with host phenology to allow reproduction when suitable hosts are available. for species not undergoing diapause or dormancy, one strategy to achieve this could be evolving long lifespans. from a physiological perspective, oxidative stress could explain how lifespan is related to degree of host specialisation. oxidative stress caused by Reactive oxygen Species (RoS) might help underpin ageing (the Free Radical Theory of Aging (FRTA)) and mediate differences in lifespan. Here, we investigated how lifespan is shaped by the degree of host specialisation, phylogeny, oxidative damage accumulation and antioxidant protection in eight species of true fruit flies (Diptera: Tephritidae). We found that lifespan was not constrained by species relatedness or oxidative damage (arguing against the fRtA); nevertheless, average lifespan was positively associated with antioxidant protection. there was no lifespan difference between generalist and specialist species, but most of the tephritids studied had long lifespans in comparison with other dipterans. Long lifespan may be a trait under selection in fruitfeeding insects that do not use diapause.

Insects that evolved in mesic regions may have difficulty establishing in xeric regions. Rhagoletis pomonella (Walsh) (Diptera: Tephritidae) was introduced into drier western North America from mesic eastern North America while Rhagoletis indifferens Curran is native to western North America. Here, we predicted that R. indifferens survives water deprivation longer than R. pomonella, as R. indifferens is more abundant than R. pomonella in dry central Washington (WA) State, USA. Sweet and bitter cherry-origin R. indifferens and apple- and hawthorn-origin R. pomonella from xeric central or mesic western WA were provided water throughout or were water-deprived at 2–4 and 14–18 d old and held at 20°C or 30/31°C and daily survival recorded. At 20°C and 30°C, western WA apple-origin R. pomonella provided water survived longer than sweet cherry-origin R. indifferens. When water-deprived, however, 2–4 d old R. indifferens, although smaller, survived significantly longer than western WA apple-origin R. pomonella of the same age. This was also generally true for 14–18 d old flies, although differences were less often significant. Central WA large-thorn hawthorn-origin R. pomonella survived water deprivation significantly longer than western WA apple-origin R. pomonella, and as long as R. indifferens. Water-deprived flies of both species survived longer at 20°C than 30/31°C. Survival analyses suggest that low water availability rather than high temperature contributes to lower R. pomonella than R. indifferens abundances in central WA, with R. pomonella populations in that region differing from western WA R. pomonella with respect to tolerance of xeric climates.
