Conteúdo: | When monitoring by the agar gel immunodiffusion test for antibody to bluetongue viruses, a sentinel flock of twenty-five lambs remained seropositive through the year, whereas in a sentinel herd of twenty calves only two individuals seroconvered and these became negative again within 2 months. a light trap operated with the calf herd yielded high numbers of Culicoides insignis Lutz (over 18.000 per trap night) along with C. filarifus Hoffman, C. pussilus Lutz, C. leopoldi Ortiz, C. foxi Ortiz, C. limai Barreto, C. diabolicus Hoffman and C. guyanensis Floch and Abonnenc. Culicoides were trapped at the sheep station which had housed the lambs 3 years following the sentinel study. No virus was isolated from pools of C. insignis, C. filariferus and C. pusillus. Six other species were collected in insufficient numbers to warrant attempteed virus isolation.
