In establishing the extermination plan for cockroaches and evaluating its effect, the so-called "cockroach index (number of cockroaches captured per trap, per day)" is useful for observing the population changes of cockroaches in the field. In order to obtain the reliable cockroach index, we investigated the most appropriate way for estimating the population of German cockroaches, Blattella germanica (L.) in the field, using sticky traps at a restaurant, and the following results were obtained. 1. Set point: A pre-test is indispensable for selecting the appropriate set point in which many traps had to be widely set for capturing stable numbers of cockroaches. Based on the result of the pre-test, sticky traps were set at the selected points. 2. Duration of trap setting: At cockroach-infested points, the sticky traps should be set for a short period because the surface of the trap might be fully covered by cockroaches in a relatively short time, while at low population points, the traps should be set for a long period to give chance for cockroaches to contact with the traps.
