Phenotypic differences between NP and TP locusts. (A) Femur length. Data was represented as Mean ± SD (Student’s t-test, ***p < 0.001, n = 30). (B) Stupor ratios of locusts under different levels of partial oxygen pressure (p O₂). Square roots of stupor ratios were calculated and then were arcsine-transformed to conduct Student’s t-test. Data were presented as Mean ± SD (Student’s t-test,*p < 0.05, **p < 0.01, n = 6). (C) Recovery time. Data were presented as Mean ± SD (Student’s t-test, **p <0.01, n = 30). (D) CO₂ production rate of locusts under a series of p O₂, or 1.6 kPa, 3.2 kPa, 6.5 kPa, 13 kPa and 21 kPa. Data were presented as Mean ± SD (Student’s t-test, *p < 0.05, n = 36).
