The Amazon forest is integral to the global climate system in part because of the high rate of rainfallrecycling through tree transpiration and biodiversity (size and species composition). However, the par-titioning of precipitation into evaporation, transpiration and runoff, has been quantified at only a fewsites. At our study site in the central Amazon, annual rainfall in 2013 was 2302 mm and latent heat fluxmeasurements made using eddy covariance revealed that 1360 mm (59%) was returned to the atmo-sphere through evaporation and transpiration. Runoff accounted for 41% of the net ecosystem waterloss. Combining annual xylem sap flux estimates with total stand sap wood area, we estimated annualstand transpiration rate to be 851 mm (36% of annual rainfall). Emergent canopy trees (diameter >30 cm;average height of 28 m) were responsible for the majority (71%) of the transpired water flux, recyclingpotentially 26% of the rainfall back to the atmosphere. By difference, we estimate that 510 mm of inter-cepted rainwater (22% of rainfall) was evaporated directly back to atmosphere from the canopy. Higheststand transpiration rates occurred during the dryer months due to both increased water vapor pressuredeficit and the onset of new leaf flush. This study provides further evidence for convergent water usecharacteristics of tropical trees and highlights the importance of large trees in tropical moist forests. Largetrees have been demonstrated to be vulnerable to drought-related mortality, and thus potentially willmake up a critical component of the response of tropical forests to climate change.

Bactrocera carambolae Drew & Hancock (Diptera: Tephritidae), native of Southeast Asia, is present in Brazil but restricted to Amapá, Pará and Roraima, where it has quarantine pest status. The possible dispersion to other fruit producing regions of Brazil could cause damages, including for exportation, due to quarantine restrictions imposed by fruit importing countries. The objective of this work was to describe the biological parameters and calculate the fertility life table of B. carambolae on grape (Vitis vinifera L.) and acerola (Malpighia emarginata DC.). The experiment was conducted in the laboratory under controlled conditions. The mean number of punctures and the mean number of eggs per female on grapes were 1.48 ± 0.05 and 9.87 ± 0.36, respectively. The mean number puparia per fruit was 0.1 ± 0.02 (grape) and 0.5 ± 0.10 (acerola). The pupal viability was 82.4% (grape) and 70.6% (acerola). The mean time ± SE of one generation, in days, was 25.8 ± 1.10 (grape) and 19.7 ± 0.21 (acerola). The mean fecundity was 1663.8 ± 501.01 (grape) and 206.9 ± 26.21 (acerola) with eggs viability of 5.6% (grape) and 12.5% (acerola). The mean longevity, in days, was 77.3 ± 12.13 on grape and 82.4 ± 4.24 on acerola. The study found that B. carambolae completes its biological cycle on grape and on acerola leaving offspring. © 2019 Sociedade Brasileira de Entomologia. Published by Elsevier Editora Ltda.
