Fig 2. Bars depicting average survivorship of late-instar Harlan nymphs (4^th–5^th instar) after each generation (F0 to F7) of selection or heat exposure at 45°C for 17.45 mins (LT₇₅ time).

Bars not connected by the same letter show statistically different survivorship rate (P<0.05; Tukey’s test).
