Abstract
In 7 out of 11 paired comparisons, 1 × 3 inch grease-coated slides were more efficient on a unit-area basis than 3 × 4 inch slides, and in 5 of these instances the smaller slides caught as many mites as did the larger ones. Trapping efficiency was not increased by mounting a funnel in front of the trapping surface. Statistical analysis showed that mite populations in volunteer wheat could be measured satisfactorily by the trapping method, and where a population was uniform a good estimate of it was provided by a single trap. The mean number of mites per day from 7 traps on margins of winter wheat fields was significantly greater than that of 13 traps in fields at some distance from the source of infestation in volunteer wheat; means of the individual trap collections did not differ significantly. The mean numbers of mites per day for 23 days from 8 traps in volunteer wheat were significantly correlated with those from 13 traps in winter wheat fields and field margins. This correlation should exist if the trapping method is efficient in measuring daily fluctuations in numbers of air-borne mites.
