title: Infestation of cockroaches (Insecta: Blattaria) in the human dwelling environments: A systematic review and meta-analysis.
abstract: Periplaneta americana, Blatta orientalis, Blattella germanica and Supella longipalpa are the most common worldwide cockroaches that mentioned in the "22 common pest" or "22 dirty" species named as "group I". They are able to infest any type of buildings. A meta-analysis review was conducted between January 2015 and July 2016 on any literature published about infestation of cockroaches. Scientific reports and papers about infestation of cockroaches and relevant topics were collected from various specific scientific websites such as PubMed, Web of Science, ScienceDirect, Springer, Elsevier, Scopus, and Google Scholar. About 271 scientific reports and papers were collected and after a preliminary review, 63 were selected to become part of the detailed synthesis review and meta-analysis. Results showed that the global world mean infestation trend of cockroaches, and B. germanica and P. americana cockroach species ranged 49.0-55.0, 40.0-70.0 and 60.0-70.0%, respectively suggests that their infestation trend are increasing. The global world mean infestation of cockroaches, and B. germanica and P. americana cockroach species were 52.3, 55.2 and 65.4, respectively. There was a significant difference between the global world mean infestation of cockroaches and P. americana cockroach species (P=0.019). The global mean infestation trend of cockroaches in the human dwelling environments and world ranged 55.0-65.0 and 50.0-70.0%, respectively suggests that their infestation trend are increasing. The global world mean infestation of cockroaches in the human dwelling environments and world were 60.4 and 57.7%, respectively. Although some factors affect the infestation of cockroaches and the sanitation and quality structure of the buildings are also being improved. While as present study reveal that the globally the world infestation trend of cockroaches are being increased and recent studies also indicate that the prevalence of asthma has increased dramatically over the decades suggest that infestation of cockroaches can directly affect the development of asthma.
