“…The overall age trends (Fig. 4) are consistent with the ecological argument that the availability of ovipositional hosts is the primary driver of medfly populations on Chios Island (Papadopoulos et al ., 2001). We pool samples from the 3 years of data because of the small sample sizes for 2003 and 2004, which do not support separate analysis.…”

SummaryThe 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 timeto-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.

“…Citrus are cultivated all along the Mediterranean coast, where climate is characterized by seasonal changes in average temperature, with a growing season from spring to fall, in which medflies proliferate, and a cool season in winter, in which field populations and damage are normally very low. Ceratitis capitata populations barely survive winter as larvae (Papadopoulos et al, 2001), or are unable to survive (Israely et al, 2004), towards the northern limit of its Mediterranean distribution. However, winter survival of medfly is greater in coastal areas, where citrus fruits are grown (Mavrikakis et al, 2000).…”

Seasonal and annual trends in Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) populations were analyzed to determine the factors that influence population fluctuations in the field. Adult flies were monitored along 2003-07 in two citrus areas in eastern Spain with similar climate, Valencia and Tarragona. Adults were present throughout the study period, even in winter. The initial annual population increase was related to previous winter and spring temperatures. Captures started to increase in April-May and usually reached a peak in July. This peak corresponded to the maximum capture period in Valencia, but not in Tarragona, where there was usually a second peak in autumn, with capture levels similar to the first peak. Gravid females were found throughout the year, even in overwintering populations of medfly. The availability of other host fruit species in the vicinity of the citrus groves may explain the differences in annual abundance and distribution of captures between the two areas studied.

“…Though the mortality of larvae and pupae during winter may be very high, proportion of the population survives and yields a small number of adults in spring (Papadopoulos et al 2000). Although not detected by fruit sampling or trapping, these adults appear in December and a proportion of them may live until the end of February (Papadopoulos et al, 2001). Reproduction is thus, possible during the early rains when host conditions become favourable giving rise to the following generation.…”

“…According to Dias and Vá squez (1993), such information can be obtained by collecting and incubating host fruits throughout their development or maturation periods. Papadopoulos et al (2001) noted that in the tropics, the phenology and abundance of fruit flies is determined by environmental temperature, rainfall, relative humidity, and host fruit availability. These environmental variables show annual fluctuations within optimum levels and are therefore, much of limiting factors in population establishment and persistence of tephritid species (Lv et al, 2008).…”

Sustainable management of fruit flies in any given ecology requires proper understanding of the population dynamics of key species in relation to host availability and the influence of abiotic factors. Studies were conducted to determine the phonological patterns of B. invadens and C. cosyra in the northern savanna ecology of Ghana. Fruit samples from 12 main host plants were collected from multiple sites at regular intervals between October, 2011 and September, 2013. These were maintained for pupal and adult fly emergence, and the results compared with the seasons and whether parameters. The widespread variability and abundance of fruit species in the ecology ensured year-round breeding of B. invadens and C. cosyra with different seasonal population levels. Dynamics of emergence of the flies fluctuated at various levels in response to availability of the host fruits and the influence of weather factors. Regression analysis indicated that precipitation showed the strongest influence on the fly populations. Infestation of B. invadens was positively related with temperature, relative humidity (RH) and precipitation while C. cosyra infestation was negatively related with RH. These studies provide baseline information on the natural anundance and occurrence periods of the main hosts and their influence on tephritid population patterns in Ghana. This can be useful in the development of sustainable control programmes by way of developing forecasting models for IPM decision making, applying sanitary measures, male annihilation techniques and setting up bait stations at the best period before the cropping season.
