Table 1. Percentage mortality realized when each strain was exposed to dry residues of the label rate (0.075% a.i.) of Temprid SC application for an exposure time targeting 80% mortality (ET80), and thus expected to impose strong selection.
Strain | Replicate | % Mortalitya (number treated) | |

aGroups of bugs were treated with the strain respective ET80 (LA1 0.1 h, CIN1 1 h, NY1 19 h; Supplemental Fig. S1).
bMore females were exposed than males to achieve a sex ratio of 5:2 ♀:♂ to reduce the deleterious impact of excessive traumatic matings.
