Thirty-three % of all flies that took a blood meal on infected danar eggs at or near the period of peak viremia (geometric mean ELD,. titer = 10'.'/0.1 ml) became infected and subsequently potential transmitters. This finding corroborates results from other systems in that the susceptibility rate with bluetongue virus (strain 62-45S) for this colony was about 30%. The period of maximum virem in the infected donor eggs began within 4 to 7 hr before the time of death of the embryo. Sixty 0;0 of those flies infected via blood meal on danar eggs and incubated at 23° to 24°C for 14 days transmitted bluetongue virus when given a meal on normal recipient eggs of either blood or allantoic fluid or both.  aBluetongue virus  aCulicoides variipennis  aDisease transmission  aFeeding behavior  aInsect vectors  aReoviridae  aSheep diseases  aVirus transmission  aCaprino  aDoença Animal  aLíngua Azul  aOvino  aVírus  aChick embryo  aTransmissão1 aJONES, R.
