Figure 2. Susceptibility to Temprid SC in selected and unselected lines from CIN1, LA1, and NY1.

In the parental generation adult bed bugs were exposed to residues of Temprid SC for intervals expected to kill 80% at 24 h after exposure for selected lines. Unselected lines were treated in the same way but without insecticide exposure. In each replicate of each strain there was a significant decrease (each χ² analysis had 1 df) in offspring mortality from the same exposure as parents received (see text for log linear analysis).
