ABSTRACT.
In Uruguay, the production of tomato (Solanum lycopersicum) in greenhouse presents pollination issues that limit its yield. The use of bumblebees (Bombus spp.) as pollinators can help overcome this problem as they perform ?buzzing pollination?, a behavior that makes them excellent pollinators of Solanaceae and particularly tomato. The aim of this study was to evaluate the effect of the native bumblebees Bombus atratus on the pro-portion of fruit set, weight, diameter, number of seeds and number of locules of tomato (LAPATAIA and ELPIDAvarieties). An experience was carried out in Canelones, where the fruits from flowers pollinated by bumblebees and from flowers not visited by insects were compared; two other experiences carried out in Salto were similar to that of Canelones, but included flowers treated with hormones. In the three analyzed greenhouses the visit of bumblebees to the flowers increased the proportion of fruit set by 13 - 47%, compared to the result obtained in flowers not visited by the insects. Also, the pollinating action of bumblebees significantly improved the weight, size, and number of seeds compared to fruits obtained from flowers without access to pollinators. This improve-ment was recorded in the experience in Canelones and only in one of the Salto's experiences. On the other hand, a positive correlation was found between the number of seeds and the weight (R2 = 0.37, R2 = 0.53; LAPATAIA, ELPIDA, respectively) in the two tomato varieties. This study is the first in Uruguay to show the benefits of using native bumblebees in tomato production in greenhouses.
RESUMEN.
En Uruguay, la producción de tomate (Solanum lycopersicum) bajo invernáculo presenta problemas de polini-zación que limitan su rendimiento. El uso de abejorros (Bombus spp.) como polinizadores puede contribuir a superar este problema, ya que realizan «polinización por zumbido», comportamiento necesario para polinizar las solanáceas y particularmente el tomate. El objetivo de este estudio fue evaluar el efecto de los abejorros nativos Bombus atratus en el porcentaje de cuajado, peso, diámetro, número de semillas y número de lóculos de tomate (variedades LAPATAIA y ELPIDA). Se realizó una experiencia en el departamento de Canelones donde se cotejaron los frutos de flores polinizadas por abejorros y flores no visitadas por los insectos; y dos experien-cias en Salto iguales a la de Canelones, pero que incluían flores tratadas con hormonas. En los tres invernáculos la visita de los abejorros a las flores incrementó el porcentaje de cuajado entre 13 y 47 % en relación con el obtenido en flores no visitadas por los insectos. La acción polinizadora de los abejorros también mejoró signifi-cativamente el peso, tamaño y número de semillas respecto a frutos obtenidos de flores sin acceso a poliniza-dores en dos de las tres experiencias realizadas. Por otro lado, en las dos variedades de tomate se encontró una correlación positiva entre el número de semillas y el peso (R2=0,37, R2=0,53; LAPATAIA, ELPIDA, respectiva-mente). Este estudio es el primero en Uruguay que muestra los beneficios de utilizar abejorros nativos para mejorar la producción de tomates en invernáculos.
RESUMO.
No Uruguai, a produção de tomate (Solanum lycopersicum)em estufas apresenta problemas de polinização que limitam sua produção. O uso de abelhas (Bombus spp.) como os polinizadores podem contribuir para su-perar esse problema, uma vez que realizam a "polinização por zumbido", um comportamento necessário para polinizar as máscaras e principalmente o tomate. O objetivo deste estudo foi avaliar o efeito da abelha nativa Bombus atratus (abelhão) sobre a porcentagem de frutos, peso, diâmetro, número de sementes e número de lóculos de tomate (variedades LAPATAIA e ELPIDA). Foi realizada uma experiência no departamento de Canelo-nes, onde foram coletados os frutos de flores polinizadas por abelhas e as flores não visitadas por insetos; e duas experiências em Salto iguais às de Canelones, mas que incluíam flores tratadas com hormônios. Nas três estufas, a visita das abelhas às flores aumentou o conjunto de frutos entre 13 e 47% em relação ao obtido em flores não visitadas pelos insetos. A ação polinizadora das abelhas também melhorou significativamente o peso,tamanho e número de sementes em comparação aos frutos obtidos de flores sem acesso aos polinizadores em duas das três experiências realizadas. Por outro lado, nas duas variedades de tomate, foi encontrada uma
correlação positiva entre o número de sementes e o peso (R2 = 0,37, R2 = 0,53; LAPATAIA, ELPIDA, respectiva-mente). Este estudo é o primeiro no Uruguai a mostrar os benefícios do uso de abelhas nativas para melhorar a produção de tomate em estufas. MenosABSTRACT.

We analyzed the variation of plant composition, forage production, and livestock diet across a broad stocking rate gradient on Eastern Hills rangelands of Uruguay. Our approach encompassed five ranches subjected to mixed sheep-cattle grazing and combined field surveys, microhistological fecal analysis, and remote sensing techniques. We hypothesized that selectivity would decrease as stocking rate increased. Vegetation data and fecal samples were obtained in 17 paddocks in 2008. To investigate the role of stocking rate on vegetation, we focused on dominant species and forage type cover. Diet composition was analyzed at forage type level. Annual net primary productivity was estimated for each paddock using the normalized difference vegetation index derived from the MODIS (Moderate Resolution Imaging Spectroradiometer) sensor. We found a clear relationship between the variation in stocking rate and floristic and forage type composition, both suggesting a deterioration of grassland conservation status. Cool season grass cover varied from 25% to 5%, from low to high stocking rates. Dicot cover showed an opposite trend, with values around 15% in the low and moderate stocking levels and reaching 35% on high-stocked paddocks. Diet composition and diet overlap between herbivores also showed clear patterns of response to stocking rate. On the other hand, livestock selectivity interacted with herbivore type. While cattle showed the expected pattern, sheep did not decrease selectivity in winter as stocking rate increased. Contrary to expectations, annual net primary productivity was similar across the different stocking rate levels and the month of maximum productivity was generally March. Our study provides strong evidence of marked rangeland degradation; however, the lack of response in terms of ANPP and the ability of sheep to maintain selectivity under high stocking rates could help to explain the lack of responsiveness in the adoption of generalized stocking adjustments by the ranchers.
