Figure 1. Calling bouts for attractive and unattractive males that were injected with either saline or LPS.

Mean (±SE) number of calls made by male G. texensis crickets during each of the ten 30 min observation periods. Regression lines for each factorial combination were fit using a mixed model (poisson family of errors) with male ID entered as a random effect. LPS-A, LPS-injected attractive males (n = 14); Saline-A, saline-injected attractive males (n = 14); LPS-U, LPS-injected unattractive males (n = 14); Saline-U, saline-injected unattractive males (n = 14).
