Cockroaches are found as the most common urban pests of tropical countries, prompting economic and serious health risk problem for humans by carrying microbes and allergens, acting as vector for various pathogens of diseases. The present study was conducted from April 2013 to March 2014 in various human dwelling localities of urban area of district Lahore, Pakistan.
Cockroaches were collected randomly by hand, food baited and sticky traps throughout the year. Four species of cockroaches ( (), (), (), and () were collected and identified from the study site
was the most dominant indoor species with highest diversity indices in study areas. Overall cockroach species diversity was highest in July-September, 2013 with highest Simpson index of diversity and Shannon index as well. was found second broadly distributed in the study area followed by and were intermediately distributed in residential areas and narrowly distributed in hospitals. Residential areas and hospitals were highly infested with followed by . Population index of for hospitals was double than residential areas. was observed as displacing in outdoor habitat through competing with its habitat and food sources.
The infestation rate of different species depends on availability of food sources, sanitary conditions and climatic conditions. Cockroach infestation can be controlled with knowledge about their biology and behavior, attention to sanitation and effective use of commercial insecticides.
蟑螂是热带国家最常见的城市害虫，通过携带微生物和过敏原，成为人类疾病各种病原体的传播媒介，给人类带来经济和严重的健康风险问题。本研究于2013年4月至2014年3月在巴基斯坦拉合尔地区市区的各个居民区进行。
全年通过手工、食物诱饵和粘性陷阱随机收集蟑螂。从研究地点收集并鉴定出四种蟑螂（ 、 、 和 ）。
在研究区域是最主要的室内物种，具有最高的多样性指数。总体蟑螂物种多样性在2013年7月至9月最高，辛普森多样性指数和香农指数也最高。 在研究区域中分布第二广泛，其次是 ， 在居民区分布中等，在医院分布狭窄。居民区和医院蟑螂侵扰程度高，其次是 。医院中 的种群指数是居民区的两倍。观察到 在室外栖息地通过与 的栖息地和食物来源竞争而取代 。
不同物种的侵扰率取决于食物来源的可用性、卫生条件和气候条件。了解蟑螂的生物学和行为、注意卫生以及有效使用商业杀虫剂可以控制蟑螂侵扰。
