Timed traps and visual observations were used to measure the distribution of activity of desert insects, principally tenbrionid beetles, in southwest Africa. Differences between species as regards seasonal and daily cycles were observed. Summer and winter faunas were almost entirely different. Measurements showed how hot and cold extremes may be avoided and how activity may be correlated with microclimatic variables. Daily activity of the tenebrionid Onymacris rugatipennis was bimodal in the summer, unimodal in the winter, and the difference could be correlated with the temperature regime.

The ability of Cytobrush and Papaplast to collect endocervical cells in vaginal smears was tested in a prospective randomized comparative study including 107 women. Endocervical cells were found more often and in greater numbers with Cytobrush, also in women over 50 years of age. Papaplast missed endocervical cells twice as often as did Cytobrush. The use of the latter instrument meant that the number of repeat smears necessitated due to the absence of endocervical cells could be considerably reduced, with consequent improvement in the cost/benefit ratio.
