ABSTRACT
Introduction and background “The more things change, the more they stay the same” is an appropriate quote for public health entomology in the 21st century. If one reads some of the oldest works on medical entomology and preventive medicine, e.g., Griscom’s speech before the New York Academy of Sciences (1855),1 the Bulletin of the Sanitary Commission (1863),2 Doan’s Insects and Disease (1910),3 and Pierce’s Sanitary Entomology (1921),4 the themes are exactly the same as those found in entomological, medical, and public health literature today:
1. Entomology bears a two-fold relationship with human health: helping provide adequate food supply and preventing disease transmission.
