  1. Yersinia strains were orally fed to first-instar M. sexta neonates. Each experiment was independently performed at least three times with a minimum of six larvae, and the average dead rates are shown. Y. enterocolitica W22703: biotype 2, serotype O:9; Y. enterocolitica 2594: biotype 2, serotype O:9; Y. enterocolitica 4466: biotype 1B, serotype O:21. 1) according to the genome sequence, 2) according to PCR analysis performed in this study.
