Fig 4. The proportion of melanic morphs at different temperatures.

Fig 4

The proportion of melanic morphs increased with an increase in the temperature. The proportion of melanism at 30°C was significantly higher than that at 26°C, and the plant hoppers at 26°C showed a significantly higher proportion of melanism than those at 22°C. Our data demonstrated the relation between the proportion of melanism and temperature.
