Horizontal transfer of diatomaceous earth, DE 51 in C. lectularius adults through a single exposed bed bug.

*LC50 values (concentration causing 50% mortality; in mg) were calculated based on 4 concentrations (5–20 mg) for each sample when an exposed bed bug was placed with 5 unexposed adult bed bugs.− not calculated due to low mortalityThere were 5 replicates of 6 bugs each. Exposed bed bug was excluded from the data (N = 25)LC50 values for the dye were not calculated due to low mortality; there was no mortality in the control group.
