“…The increase in MDA content observed with age in both the sexes of Z. paravittiger is attributed to increased free radical damage and decreased antioxidant defense. These findings corroborate with other reports on Z. paravittiger [24,35] and rotifer, Asplanchna brightwelli [36], Females exhibited lower MDA content and higher life span as com pared to males who had higher MDA content. This is in agreement with Cutler [37] who stated that lipid peroxidation is inversely cor related with longevity in mammals.…”

Zaprionus paravittiger fed with vitamin E supplemented diet (1, 5 and 10 μg/ml) showed an increase in median and maximum life spans. Further increase in concentration accelerated the mortality rate. Females exhibited longer life span as compared to males. Malondialdehyde (MDA) content and antioxidant enzymes (catalase and peroxidase) were measured in control and optimum concentration of vitamin E (5 μg/ml)-fed flies at various age intervals. MDA content showed an increase with age in control and vitamin E-fed group whereas catalase and proxidase activities showed a decrease with age. The females exhibited lower MDA content and higher activities of catalase and peroxidase as compared to males in control and vitamin E group. Vitamin E feeding caused a significant decrease in MDA and increase in catalase and peroxidase activities. These findings suggest that vitamin E has dose-dependent and sex-specific influence on longevity of Z. paravittiger and support the view that longevity and activity of antioxidant enzymes are positively linked.

“…The values found in literature are those of control groups used for investigation of effects of various antioxidants on the lifespan and ageing characteristics of Z. paravittiger Godbole and Vaidya, 1972 (= Z. indianus). According to SHARMA et al (1995), the mean longevity for males and females kept in the same vial is 30.6 days (maximum lifespan: 70 days) and 34.3 days (maximum lifespan: 76 days) respectively; values very similar to those obtained by KAKKAR et al (1996), 35.1 days for males and 41.7 days for females. Both studies were made in corn-meal agar medium at 26 ± 2 °C.…”

“…Survival of males and females kept in the same vial ranged from 11 to 150 days (81.7 ± 5.0) for males, and from 4 to 145 days (92.6 ± 4.6) for females. In both situations, longevity was higher than that observed by SHARMA et al (1995) and KAKKAR et al (1996). Females lived longer than males, however the differences were significant only for virgin flies (t = 6.39; P < 0.01).…”

ABSTRACT. This study aimed to evaluate fitness components of Zaprionus indianus Gupta, 1970, a species recently introduced in Brazil and currently in process of colonization. Longevity, productivity, developmental speed and viability of flies sampled from a population from Mirassol (state of São Paulo, Brazil) were evaluated. Longevity was higher than that of some Indian populations and productivity was similar or higher than in other Drosophilidae. Time of development, one of the main fitness components for competition, was very similar to the values scored in Drosophila sturtevanti Duda, 1927, a species that occurs in high frequencies in the same area as Z. indianus. These data might contribute further for understanding the colonization success of this newcomer species in South America.KEYWORDS. Fitness components, productivity, viability, time of development, Zaprionus. (CHASSAGNARD & TSACAS, 1993;CHASSAGNARD, 1996) and Anaprionus, with 12 species from Australia and Southeastern Asia (TSACAS & CHASSAGNARD, 1990;GUPTA & GUPTA, 1991). Zaprionus indianus seems to be the unique species of Zaprionus subgenus that is spreading throughout the tropical regions, probably due to the intensification of the world fruit commerce (VILELA et al., 2001). This species occurs throughout Africa, India and Saudi Arabia, as well as in islands of the Indian Ocean (Comores, Madagascar, Seychelles, Mauritius and Réunion) and of the Atlantic Ocean (Canary and Saint Helena) (CHASSAGNARD & KRAAIJEVELD, 1991;CHASSAGNARD & TSACAS, 1993). In Africa, it has been found in 74 species of 31 botanical families; among them, several are native of the American continent (avocado, pineapple, guava and papaya) or have been here introduced (carambola, banana, citrus, mango and fig) (LACHAISE & TSACAS, 1983).The occurrence of Z. indianus in South America was first reported in Brazil (VILELA, 1999) and then in Uruguay (GOÑI et al., 2001). It has been suggested that this species may have been introduced in Brazil by airplane transportation from African or Asian countries to the city of São Paulo, possibly in meals (fruits for instance) offered to passengers (VILELA, 1999;TIDON et al., 2003). Zaprionus indianus has been found in all regions of Brazil (CASTRO & VALENTE, 2001;VILELA, 1999;VILELA et al., 2001;TIDON et al., 2003).Although Z. indianus has not been considered as a pest in the Afrotropical region, it seems to be reaching the pest status in the fig main producer areas of the state of São Paulo (Brazil). In 1999, 50% of the fig crops were lost due to oviposition of these flies (VILELA et al., 2001). Since Z. indianus has also been found in other tropical fruits, such as citrus, persimmon, guava, jambul and acerola (VILELA et al., 2001), it is possible that this species will become invasive in the culture of these agricultural products, thus causing damages to regional economies.Little information about Z. indianus reproductive biology is found in the literature. Therefore, the quantification of fitness components in laboratory is an important t...

“…Our findings that PG supplementation to the diet increases the LT50 and LT100 life spans of 7. paravittiger is in agreement with other reports where antioxidant supplementation has prolonged the life span [25,26]. PG has been reported to be a scavenger of oxyradicals [16][17][18][19].…”

Zaprionus paravittiger fed on propyl gallate (PG) supplemented diet (2.5, 25 and 250 µg/ml) showed an increase in life span. Further increase in concentration (2500, 5000 and 7500 µg/ml) accelerated the mortality rate. Females exhibited longer life span as compared to males. Antioxidant enzymes (catalase, peroxidase and glutathione reductase) were measured in control and optimum concentration of PG (25 µg/ml) fed flies at various age intervals. Antioxidant enzyme activities showed an increase during reproductive phase. Catalase and glutathione reductase activities decreased with age however no significant change was observed in peroxidase activity. The females exhibited higher enzyme activities as compared to males in control and PG fed group at most of the age intervals. PG feeding caused a significant increase in catalase and glutathione reductase activities in both the sexes. These findings suggest the PG has dose dependent and sex specific influence on longevity of Z. paravittiger and support the view that longevity and activity of antioxidant enzymes are positively linked.
