Abstract: O objetivo deste trabalho foi avaliar o efeito de inseticidas no controle da mosca-branca (Bemisia argentifolii Bellows & Perring, 1994) na incidência do vírus-do-mosaico-dourado e na produtividade do feijoeiro. Utilizou-se de tratamento de sementes com imidacloprid ou thiamethoxam, e de pulveriza es de inseticidas, em intervalos semanais. O experimento foi realizado no campo, em área irrigada, em Petrolina, PE, em blocos ao acaso, com cinco tratamentos e quatro repeti es. Houve redu o significativa no número médio de ovos, de ninfas e de adultos da mosca-branca e na porcentagem de infec o pelo vírus-do-mosaico-dourado do feijoeiro. A produtividade nas parcelas tratadas variou de 1.930 a 2.405 kg/ha, enquanto na testemunha foi de 1.490 kg/ha. N o foi observada diferen a significativa entre os tratamentos, no número de vagens/planta e peso de 100 sementes.

Abstract: background: myocardial perfusion radionuclide imaging (mpri) is a noninvasive method extremely useful for evaluating ischemia in patients with coronary disease. however, the idea that this method would not be effective for patients with multivessel coronary disease is still entertained. objective: assess the value of mpri with gated-spect for tracing pharmacological stress-induced ischemia in patients with multivessel obstructive coronary disease. methods: we evaluated 68 patients with multivessel obstructive coronary disease applying coronary angiography for performing mpri under pharmacologic stress with dipyridamole. the tests were analyzed by two nuclear medicine physicians without prior knowledge of the result of the coronary angiography. results: gated-spect revealed that, out of the patients, 64 (92.8%) showed images of perfusion abnormalities and 4 (7.2%) showed normal perfusion, given that three of the latter showed functional changes. conclusion: mpri has shown high value for identifying patients with multivessel coronary disease, since most patients had perfusion abnormalities indicative of ischemia.

Abstract: this study describes aspects of floral biology and the reproductive system of passiflora edulis f. flavicarpa (passifloraceae), including foraging patterns of the floral visitors in the region of s?o francisco valley. the study was carried out in irrigated orchards in the mani?oba project, in juazeiro-ba, during 2005 and 2006. the floral anthesis occurred between midday and 1 pm. flower closing started at 6 pm and finished around 1 am. the time for style deflexion was 71,4 ± 12,4 min, about 5% of the flowers remained with the style undefexed. the stigmas were receptive during the entire anthesis and the pollen grains presented 94% viability. the nectar volume was in average 100 μl, with 48% of sugar concentration . the average number of pollen grains/flower was 140,595 ± 34,175 and 426 ± 77 of ovules/ovary. the highest rates were obtained after manual crossed pollination (74%), confirming the existence of a system of self-incompatibility. we registered 10% of flowers with four stigmas, which when manually pollinated, produced bigger fruits with a higher number of seeds (477,7 ± 76,8). we found a positive correlation between the number of seeds and the weight of the fruits. the flower visitors were apis mellifera, trigona spinipes, xylocopa grisescens, x. frontalis and x. cearensis. a. mellifera and t. spinipes being pollen and nectar robbers, respectively. bees of the genus xylocopa were more frequent during the dry season and a. mellifera during the wet season. the effective pollinators were x. grisescens and x. frontalis. we found that they were limited in number in the studied areas. however they were found to be more frequent in other plant species during the rainy season which indicates that these plant species compete with the passion fruit for pollination service.
