THE IMPACT OF THE BOLL WEEVIL, 1892-1932. Fabian Lange, Yale University. Alan L. Olmstead, UC Davis. Paul W. Rhode, Univ. of Arizona & NBER. February 2008. Abstract: The boll weevil is Americaâs most celebrated agricultural pest.
The bacterium responsible for the infection, Bordetella pertussis, was not identified until 1906. In the pre-vaccination era (during the 1920s and '30s), there were over 250,000 cases of whooping cough per year in the U.S., with up to 9,000 deaths. In the 1940s, the pertussis vaccine, combined with diphtheria and tetanus toxoids (DTP), was introduced. By 1976, the incidence of whooping cough in the U.S. had decreased by over 99%.
