    Notizen: Summary Intercolonial differences in raiding activity were investigated in the field on 9 colonies of the slavemaking antPolyergus samurai. Duration of raiding season, the mean start time of the first raiding trip in a day, the mean speed of outbound and inbound trips, and the mean distance to target nests varied significantly among colonies. The variance in start time of raiding was correlated with that in soil temperature and diurnal change pattern in soil temperature at the nest sites. The speed of trips and the first day with trips in the season also correlated with soil temperature at the nest site. Simple environmental factors well explained the observed variances in raiding activity among colonies. Therefore, raiding behaviour ofP. samurai seemed to be a stereotyped behaviour that is regulated through simple environmental factors.

    Notizen: Summary Raiding behavior of the Japanese slave-making antPolyergus samurai was investigated in the field. Raiding trips occurred from early June to early September. A raiding column of several hundreds workers would rush into a target nest and rob mainly worker pupae of the host species,Formica (Serviformica) japonica. Most trips occurred on sunny days. Air temperature, soil temperature, relative humidity, and radiation energy at the ground surface were significantly different between days with and without raiding trips. Nuptial flights occurred on hot, sunny days, and mostPolyergus colonies released alates simultaneously. Behaviors of newly mated queens are also provided and are compared with otherPolyergus species.
