They are dorso-ventrally flattened for ease of travel through the hairs of the host. Bovicola bovis Scientific classification Kingdom: Abstract The spatial distribution of chewing lice Bovicola lvis on their hosts was examined in Polypay and Columbia ewes initially artificially infested on the midside or the neck.

The degree to which the fleece was bovicla was assessed 20 minutes after dipping and showed that the wettable powder dips penetrated the fleece less than the emulsifiable concentrate dips.
The main reason that these two industries are the ones affected is that the louse causes reduction in weight gain and milk production. Comparisons of lice per part with the numbers of lice extracted from clipped patches indicated that a sheep with wool bearing area of 1 m2 and a mean count of one louse per 10 cm fleece parting carried approximately lice.
