Fig. 1

Enzyme assays in the two different developmental stages of T. urticae (nymphs and adults) after ethyl formate (EF) and phosphine (PH3) treatment, respectively. COX: cytochrome c oxidase; AChE: acetylcholinesterase; CE: carboxylesterase; GST: glutathione-S-transferase. The enzyme activities were expressed as μmol/mg min of the mite. Different letters on the bars indicate statistical differences between phosphine-treated samples and the control (p < 0.05). Treated concentrations were equivalent to LC10 (4.32 mg/L for EF; 0.042 mg/L for PH3) and LC50 (5.84 mg/L for EF; 0.059 mg/L for PH3) values
