“…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...

Background: Numerous recent studies have suggested that oxidative damage may be important in the ageing process, and lipid peroxidation is an important biological consequence of oxidative cellular damage. Objective: The aim of this work was to analyze the activities of the two protective enzymes, superoxide dismutase (SOD) and catalase (CAT), and the levels of malondialdehyde (MDA) to examine the relationship between the ageing process and defence antioxidant and lipid peroxidation. Method: SOD activity was measured in red blood cells using the Minami and Yoshikawa method; CAT activity was measured in hemolysates by the Aebi method, and MDA levels were measured in erythrocytes by high-performance liquid chromatography. Results: SOD activity shows statistically significant differences between newborns and the rest of the sample (ANOVA p < 0.001; Student-Newman-Keuls test p < 0.001). CAT activity did not show significant differences between the age groups. We observed statistically significant differences in MDA levels between the different groups (ANOVA p < 0.001; Student-Newman-Keuls test p < 0.05). In the regression analysis and rectilinear/curvilinear adjustment compared to age, SOD and CAT showed coefficients close to zero (SOD linear = 0.16; SOD exponential = 0.15; CAT linear = 0.056; CAT exponential = 0.068), indicating in that way their independence from age. Only MDA obtained a regression coefficient superior to 0.75 (p < 0.05). The best adjustment was reached through an exponential expression, giving the following parametric relation: MDA = 103.117e^0.0021.AGE. No statistically significant variation in SOD and CAT activity and MDA levels, related to sex could be demonstrated. Conclusions: Our data show that old age is associated with an increase in systemic oxidative stress.
