  1. WLterm = Weight loss (%) due to termites degradation; TSR = Termite Survival Rates; EtOH = Ethanol; RR = Raw Resin; VS = Visual Score: "0" = No attack; "1" = Attempted attack; "2" = Light attack; "3" = Medium attack; "4" = Strong attack
  2. ± = The plus/minus values shown are the upper and lower limits of the 95% confidence interval
