FIG. 3.

Insecticidal activities of E. cloacae harboring the tcdA1B1 genes against the Formosan subterranean termite. Termites were exposed to the bacterial cultures for 29 days. A, E. cloacae harboring tcdA1B1 genes; B, E. cloacae harboring a transposon without any inserted genes; C, E. cloacae wild-type strain; D, double-distilled water control. The data are averages for three replicates. The error bars indicate standard deviations. Post hoc t tests were performed for each day. For each day bars labeled with different letters are significantly different (P < 0.05).
