Metrics of bed bug orientation to heated or cooled targets. The effect of target coil temperature on (A) velocity, (B) angular speed, (C) average distance to the wall and (D) total distance traveled by HH strain bed bugs. Only bugs that contacted the coil during the 5 min experiment were included in the analysis. Means±s.e.m. are plotted and equations describing these relationships are as follows:
where angular speed is in rad s
−1, distance to the wall is in mm and distance traveled is in mm. A minimum sample size of N=14 was used for each temperature.
