THE DETECTION OF LICE (BOVICOLA OVIS) IN MOBS OF SHEEP - A COMPARISON OF FLEECE PARTING, THE LAMP TEST AND THE TABLE LOCKS TEST

摘要

Knowledge of the presence or absence of lice in a flock of sheep enables wool growers to make informed decisions as to the need for insecticidal treatments. However, with inapparent infestations, traditional methods of detection are not sufficiently sensitive and, as a consequence, flocks may be left untreated, Conversely, the routine application of insecticide to sheep with no sign of infestation is an unnecessary cost. The sensitivity of 3 procedures for detecting lice was evaluated in 68 mobs of sheep from 50 farms.
