Mean adult tick counts reached a maximum of 27.8 per undipped sheep, the ?tick effects? being evident on the 16th and 35th days following this peak. Mean tick counts on a control group of dipped animals were less than two per sheep.  aHaemaphysalis longicornis  aParasitology  aSheep diseases  aTick infestations  aCarrapato  aInfestação  aOvino  aParasitologia  aIxodideo1 aPEARCE, D.
