This study aimed to investigate the species distribution of indoor cockroaches in dwellings in Bangkok. Commercial sticky traps were used to catch cockroaches in 128 private residences (40 single houses, 49 townhouses, 39 apartments), 34 offices, and 30 small groceries. The cockroaches were identified as Periplaneta americana, Supella longipalpa, Blattella germanica, Neostylopyga rhombifolia, P. brunnea, P. australasiae, Pycnoscelus surinamensis, and B. lituricallis; two were unidentified species. The most common species were P. americana, S. longipalpa and B. germanica--most of which were nymphal stages. P. americana and S. longipalpa infested all kinds of buildings, especially private residences (50.0% and 17.2%, respectively) and offices (61.8% and 58.8%, respectively); they were also found mostly (15.1%) in mixed infestation and with no predominant species. B. germanica (26.7%) were significantly predominant in groceries. Air conditioners have no influence on cockroach distribution.
本研究旨在调查曼谷住宅内室内蟑螂的种类分布。使用商业粘虫板在128处私人住宅（40栋独栋房屋、49栋联排别墅、39套公寓）、34间办公室和30家小杂货店捕捉蟑螂。这些蟑螂被鉴定为美洲大蠊、长翅污斑蠊、德国小蠊、褐斑大蠊、黑胸大蠊、澳洲大蠊、拟裸蠊和亮斑扁角水虻；有两种为未鉴定物种。最常见的物种是美洲大蠊、长翅污斑蠊和德国小蠊——其中大多数处于若虫阶段。美洲大蠊和长翅污斑蠊侵扰各类建筑，尤其是私人住宅（分别为50.0%和17.2%）和办公室（分别为61.8%和58.8%）；它们也大多（15.1%）出现在混合侵扰且无优势物种的环境中。德国小蠊（26.7%）在杂货店内显著占优势。空调对蟑螂分布没有影响。
