May someone kindly advise as to what specific databases I could consult in regard to the above topic? Most databases such as EBSCOhost, GOOGLE Scholar, MedLine mainly have articles dealing with vector control from a "mosquito" perspective as this vector is a scourge in modern Public Health research. From an urban prespective where issues such as overcrowding, informal and squallor conditions, waste, sanitation etc. are rampant and thereby causing urban vector problem such as rodent infestation, flies, cockroaches, and to some extent mosquitoes.
