Figure 5. Horizontal transfer of DE 51, neem, ryania and rotenone in C. lectularius through an exposed bug; N = 4 replicates of 6 insects each; one bed bug with prior exposure to 20 mg of DE 51, neem, ryania and rotenone was placed with 5 untreated bugs; control insects were not exposed to the dust.

There were 4 replicates of 6 bugs each. Exposed bed bug was excluded from the data (N = 20). ** Significantly different from all treatments including control. *Significantly different from control.
