Activities of tabanids (Diptera, Tabanidae) attacking domestic duck-Cairina moschata (Linnaeus) (Aves, Anatidae), introduced in a forest area in the Central Amazon, Manaus, Brazil

Presented here are the feeding habits, attack behavior, daily and annual activity of adult of Phorcotabanus cinereus (Wiedeman, 1821), Chrysops laetus (Fabricius, 1805) and Phaeotabanus cajennensis (Fabricius, 1787), while biting a domestic duck, Cairina moschata (Linnaeus, 1758). The last two species were recorded for the first time attacking birds. This study comprehended monthly observations of two consecutive days from April/97 to March/98 between 5:30 a.m. and 6:30 p.m. at the Army Instructional Base ((BI-2/CIGS) near Manaus. Annual occurrence of P. cinereus was from July to September, with a daily occurrence between 9:00 a.m. and 5:00 p.m. and highest activity at 12:00 a.m. and 2:00 p.m. C. laetus ocurred from June to October; with a daily occurrence between 8:00 a.m. and 3 p.m. and highest activity at 11:00 and 12:00 a.m. Occurrence of P. cajennensis with one specimen only, was in July between 10:00 and 11:00 a.m.

Eleven-year physical activity trends in a Swiss urban area.

OBJECTIVE: Regular physical activity is a major health determinant. Little is known about physical activity trends. We evaluated whether adult physical activity levels are changing in a Swiss urban state (Geneva). METHOD: We analyzed 11-year trends of physical activity indicators, including 3+MET-minutes per week and physical activity outside working hours, in population representative adults (n=9320, aged 35-74years, 50% women), relating declared physical activity to socioeconomic status, lifestyle, and clinical and blood markers. RESULTS: Combining yearly cohorts from 1999 to 2009, we found a significant trend for increased physical activity levels. Weekly age and sex adjusted 3+MET-minutes per week increased from 3023 to 3752, between 1999 and 2009 (P=0.02). The increase also concerned physical activity outside working hours (+18kcal/day/year). There was a shift from low levels of physical activity levels towards higher activities. Physical activity indicators were associated with socioeconomic status, comorbidities, and biological and anthropometric measures. The trend for increased physical activity was more prominent over the latter 5years. CONCLUSION: We found that physical activity levels have increased in an urban Swiss state. The increase is significant but small, and further efforts to promote physical activity are therefore warranted.

Influence of Apion sp. (Brentidae, Apioninae) stem-galls on induced resistance and leaf area of Diospyros hispida (Ebenaceae)

We addressed the influence of the stem galls induced by an unidentified species of Apion sensu lato (Brentidae, Apioninae) on the host plant, Diospyros hispida (Ebenaceae) leaf area and induced resistance against a Cecidomyiidae (Diptera) leaf galls. The study was performed in a cerrado vegetation in Serra do Cipó, southeastern Brazil. Although the number of leaves produced on galled and ungalled shoots did not differ statically (p>0.05), the presence of the apionid galls influenced the area of the leaves on the attacked shoots of D. hispida. Leaves on galled stems were approximately 50% smaller compared to leaves in healthy stems. The average of the cecidomyiid leaf galls successfully induced on healthy shoots was higher compared to galls successfully induced on shoots galled by the apionid. The same pattern was found for the abundance of hypersensitive reactions against the cedidomyiid gall induction. Therefore, the ability of the cecidomyiid to successfully induce galls was not influenced by the apionid galler.
