This list acts as a Supplementary Appendix for an article submitted in 2020 to the journal BioControl, entitled "Summary of classical biological control introductions of entomopathogens and nematodes for insect control" (Hajek, Gardescu, & Delalibera). This list provides a brief summary of information on releases of non-native pathogen or nematode biological control agents, as reported in the scientific literature, from the 1800s to early 2000s. The list is organized by agent species and the target insect/mite pest species, and includes the country/region and year of each release. This list summarizes the information presented in a format organized by target pest Orders in "Classical biological control of insects and mites: A worldwide catalogue of pathogen and nematode introductions" (Hajek, Gardescu & Delalibera, 2016) USDA FHTET-2016-06.
