  1. Estimated incidence rate ratio (IRR); confidence interval (CI) and corresponding P-values based on comparison to the control (BG lure baited trap) following generalized linear model (GLM) with negative binomial error structure and log link in R 3.1.0 software. The IRR for the control is 1; values above this indicate better performance while values below indicate under performance relative to the control. Blend 1; propionic acid and 3-methylbutyric acid, Blend 2; nonanal + octanal. Blend 3; Blend 1 + Blend 2.
