Medical and veterinary entomology encompasses the study of the insects which are vectors, transmit disease, cause wounds, inject venom and create nuisances together with their application as useful providers of drugs, and model systems for genetic studies. Thus the study on insects and how they affect the human and animal lives have gained importance in recent times. Insect Genomics involving the studies of the whole genome sequences are being developed and gene expression and regulation studies are elucidating their roles in regulating the vector competence. This finds importance in deducing strategies for vector control thereby preventing disease spread that is fatal to man and animal life. In this review we have studied the medical entomology (i) from historical perspective (ii) diverse role of arthropods in causing diseases (iii) common pathogens transmitted by arthropod vectors (iv) major arthropod borne diseases (v) pharmaceutically important insects. The future scope of this review remains to study in depth insects under Diptera that are causative agents of diseases.
