1 A cloth cage with collecting bottles is described for trapping adult insects emerging from beneath tree bark in low densities. 2 The traps had little effect on temperature, although fluctuations tended to be slightly damped. They probably delayed emergence of adult codling moth, Cydia pomonella by a day or two only. 3 In a test of trap efficiency, all codling moths which developed to the adult stage inside the traps were recorded in the collecting bottles; a few larvae remained in diapause, and the proportion of these was greater in the traps than in an outdoor insectary, so that traps tend to provide a slight underestimate of adult numbers.
