Volatile Chemicals of Adults and Nymphs of the Eucalyptus Pest, Thaumastocoris peregrinus (Heteroptera: Thaumastocoridae)

Table 2

Quantification (μg) of esters identified in whole body extracts of Thaumastocoris peregrinus (Heteroptera: Thaumastocoridae) virgin and mated males and females of different ages; 3–9 days (1) and 22–33 days (3). For each ester identified, ns: not statistically different, and *: statistically different; SE: standard error. Statistical comparisons: GLM (generalized linear model) with Gaussian distribution (𝑃>0.05).
