<span style="font-family: arial,helvetica;">The efficacy of an amitraz / cypermethrin pour-on preparation (1 % w/v each) was tested against natural tick infestations of buffaloes, eland and blesbok in three separate trials. The eland were also treated with a 0.02 % abamectin (w/v) acaricidal pour-on preparation. The amitraz / cypermethrin pour-on was effective against <em>Amblyomma hebraeum, Rhipicephalus evertsi evertsi, Rhipicephalus appendiculatus</em> and <em>Hyalomma marginatum rufipes</em> on the buffaloes. Both acaricides were effective against <em>R. appendiculatus</em> and <em>Rhipicephalus (Boophilus) decoloratus</em> in the eland. The amitraz / cypermethrin acaricide was effective against <em>R. (Boophilus) decoloratus</em> in the blesbok. <br />Ticks can cause damage to the skins, secondary infections, abscesses, anaemia, loss of condition, tick toxicosis and act as vectors of infectious diseases. Introduction of hosts and / or ticks from endemic to non-endemic areas because of translocation of game, may lead to severe losses. The pouron acaricides tested were effective against natural tick infestations and should always be used according to the manufacturer's instructions and efficacy claims.</span>
<span style="font-family: arial,helvetica;">Three hundred and eighty-four samples of leaf litter, soil, faeces from domestic and game animals, compost and aqueous cultures of infective nematode larvae contaminated with unidentified fungi were plated out on water agar, baited with pure infective larvae of <em>Haemonchus contortus</em>, incubated and examined for the presence of nematophagous fungi. <br /><em>Duddingtonia flagrans</em> was isolated from five samples, and 73 samples were positive for other nematophagous fungi.</span>
