Investigation of habitat for cockroaches in an outdoor urban environment XI Cockroaches captured in open spaces close to high-rise buildings and tree hollows in an urban park in Tokyo

Abstract

Cockroaches were collected with sticky traps in open spaces close to high-rise buildings and in tree hollows in an urban park, Minato-ku, Tokyo, from June to December 2011. The smoky-brown cockroach, Periplaneta fuliginosa, was captured in both places, and the Japanese cockroach P. japonica was captured only in the tree hollows in the urban park. More numbers of P. fuliginosa were collected than P. japonica. Up to 90% of specimens collected in open spaces were in nymphal stages, and 74% of specimens collected in tree hollows were P. fuliginosa.
