Experiments were carried out to investigate the influence of different temperatures (27℃ and 15℃) on the behavioural interaction between two harbouring final instars and/or adults in each of four species of cockroaches, Periplaneta fuliginosa. P. americana, P. japonica, and Blattella germanica. Rectangular paper-pipes of 12cm×14cm×different heights (2cm, 1cm) or those of 3cm×2cm×different heights (1cm, 0.5cm) were used as harbourage shelters. These shelters were placed side by side in a test container and two insects of the same stage were released into the container. Each test was replicated eight or ten times. The results of the experiments can be summarized as follows. I. Periplaneta species : When tested at 27℃ with 1cm and 2cm shelters, adults, as well as final instar nymphs, tended to enter into separate shelters. At 15℃, however, they were usually found in couples in one of the two shelters, mostly in 1cm one. This suggests that the rejecting behaviour of Periplaneta species is suppressed through some mechanism under cooler conditions. II. Blattella germanica : More than 50% of adults were found in separate shelters or out of them irrespective of temperature conditions, suggesting that the harbouring behaviour of this species is different from that of the Periplaneta species.
