Abstract: The main purpose of this study was to test the hypotheses that major changes in age structure occur in wild populations of the Mediterranean fruit fly (medfly) and that a substantial fraction of individuals survive to middle age and beyond (> 3--4 weeks). We thus brought reference life tables and deconvolution models to bear on medfly mortality data gathered from a 3-year study of field- captured individuals that were monitored in the laboratory. The average time-to-death of captured females differed between sampling dates by 23.9, 22.7, and 37.0 days in the 2003, 2004, and 2005 field seasons, respectively. These shifts in average times-to-death provided evidence of changes in population age structure. Estimates indicated that middle-aged medflies (> 30 days) were common in the population. A surprise in the study was the extraordinary longevity observed in field-captured medflies. For example, 19 captured females but no reference females survived in the laboratory for 140 days or more, and 6 captured but no reference males survived in the laboratory for 170 days or more. This paper advances the study of aging in the wild by introducing a new method for estimating age structure in insect populations, demonstrating that major changes in age structure occur in field populations of insects, showing that middle-aged individuals are common in the wild, and revealing the extraordinary lifespans of wild-caught individuals due to their early life experience in the field.

ABSTRACT = {The main purpose of this study was to test the hypotheses that
major changes in age structure occur in wild populations of the
Mediterranean fruit fly (medfly) and that a substantial fraction of
individuals survive to middle age and beyond (> 3--4 weeks). We
thus brought reference life tables and deconvolution models to bear
on medfly mortality data gathered from a 3-year study of field-
captured individuals that were monitored in the laboratory. The
average time-to-death of captured females differed between sampling
dates by 23.9, 22.7, and 37.0 days in the 2003, 2004, and 2005
field seasons, respectively. These shifts in average times-to-death
provided evidence of changes in population age structure. Estimates
indicated that middle-aged medflies (> 30 days) were common in the
population. A surprise in the study was the extraordinary longevity
observed in field-captured medflies. For example, 19 captured
females but no reference females survived in the laboratory for 140
days or more, and 6 captured but no reference males survived in the
laboratory for 170 days or more. This paper advances the study of
aging in the wild by introducing a new method for estimating age
structure in insect populations, demonstrating that major changes
in age structure occur in field populations of insects, showing
that middle-aged individuals are common in the wild, and revealing
