Resumo: No Brasil, estima-se que as intoxicações por plantas tóxicas que contém monofluoroacetato de sódio (MFA) causam a morte de aproximadamente 500.000 bovinosao ano. A inoculação ruminal de bactérias que degradam MFA tem sido proposta como uma forma de prevenir a intoxicação. O presente trabalho teve como objetivo avaliar, em caprinos, a resistência ao MFA presente em Amorimia septentrionalis, induzida por inoculação ruminal das bactérias Pigmentiphaga kullae e Ancylobacter dichloromethanicus. Doze caprinos, que nunca tiveram contato prévio com plantas que contêm MFA, foram divididos em dois grupos, com seis animais cada. No grupo 1, 60 mL de uma mistura das duas bactérias foi inoculada, diariamente, durante 10 dias em cada caprino. No grupo 2, os caprinos não receberam as bactérias. A partir do 10º dia de inoculação, A. septentrionalis foi administrada, diariamente, na dose de 5g/kg de peso vivo, sendo interrompida em cada animal após a observação dos primeiros sinais clínicos da intoxicação. Os caprinos do grupo 1 apresentaram sinais clínicos 5,83±2,56 dias após a administração da planta o que diferiu significativamente (p=0,037) dos caprinos do grupo 2, que apresentaram sinais clínicos aos 2,67±0,52 dias. A quantidade de planta ingerida pelos caprinos inoculados (28,83±12,97g/kg) e os não inoculados (12,03±3,65g/kg) para desencadear os sinais clínicos foi, também, estatisticamente diferente entre os grupos (p=0,025). Conclui-se que a administração intraruminal de Pigmentiphaga kullae e Ancylobacter dichloromethanicus induz resistência à intoxicação por plantas que contêm MFA. [Resistance to poisoning by Amorimia septentrionalis in goats induced by ruminal inoculation of the bacteria Pigmentiphaga kullae and Ancylobacter dichloromethanicus]. Abstract: In Brazil is estimated that poisoning of livestock by sodium monofluoroacetate (MFA) containing plants causes the death of about 500.000 cattle per year. The ruminal inoculation of bacteria that degrade MFA has been proposed as a way to prevent the poisoning. This study aimed to evaluate in goats resistance to the MFA-containing plant Amorimia septentrionalis induced by ruminal inoculation of the bacteria Pigmentiphaga kullae and Ancylobacter dichloromethanicus. Twelve goats, without previous contact with MFA-containing plants, were divided into two groups of six animals each. In group 1, 60ml of a mixture of the two bacteria was inoculated every day for 10 days into each goat. In group 2, the goats did not receive the bacteria. At the 10th day of inoculation, A. septentrionalis began to be administered daily at a dose of 5g/kg body weight to both groups. The administration was interrupted in each goat after first clinical signs of poisoning were observed.. The goats of group 1 showed clinical signs 5.83±2.56 days after the administration of the plant, what differed significantly (p=0.037) from goats of group 2, that showed clinical signs 2.67±0 52 days after the beginning of ingestion. The amount of A. septentrionalis ingested by inoculated goats (28.83±12.97g/kg) to cause clinical sings was significantly greater (p=0.025) than the amount ingested by the non-inoculated (12.03±3.65) goats to cause clinical signs and was also statistically different between the groups. We concluded that the intraruminal administration of Pigmentiphaga kullae and Ancylobacter dichloromethanicus increases the resistance to poisoning by MFA-containing plants.

ABSTRACT.
Grapevine phylloxera, Daktulosphaira vitifoliae (Fitch) (Hemiptera: Phylloxeridae) is a worldwide pest of Vitis species. It has forms that feed on leaves and roots. Root forms predominate on Vitis vinifera (L.) cultivars, while leaf forms predominate on Vitis species from its native American range. Recently, high densities of D. vitifoliae infestations in leaves of V. vinifera in Brazil, Peru, and Uruguay have been reported. The aims of this study were to determine the seasonal development of grape phylloxera, quantify infestation levels on V. vinifera leaves, and compare them with infestation levels on leaves of a rootstock of American origin. Studies were conducted in two vineyards in Uruguay from 2004-2007. Terminal shoots of 3309 C and Cabernet Sauvignon, Chardonnay, Tannat, Viognier, grafted onto resistant rootstock, were sampled weekly and leaves examined for gall presence and insect life stage. First galls were detected in early October; eggs began to appear within two weeks. Two oviposition peaks occurred by the end of December, and they coincided with bursts of shoot growth. On 3309C rootstock, oviposition peaks were more frequent than on the European cultivars. Based on thermal accumulation, D. vitifoliae could complete eight generations a year in Uruguay. Rootstock 3309C suffered the greatest damage but in some cases was similar to the European cultivars. Damage to Chardonnay, Cabernet Sauvignon and Viognier were also high. There were no galls on Tannat. The 2005-2006 season was characterized by low infestation rates caused by a prolonged drought that affected vegetative growth. There were also differences between vineyards, where the vigorous plants suffering more damage. Leaf galling phylloxera incidence and damage were mainly associated to the cultivar but plant vigor and environmental factors also contributed to increase the incidence.
