Fig 2. Resistance Levels per each acaricide and bioassay.
Resistance Levels for Adult Immersion Test were divided in three categories i.e. Susceptible (<50%), Medium resistance (51 to 75%) and High resistance (>76%); for Larval Test, four categories were identified i.e. high (>51%), medium (21–50%) and low (11–20%) resistance and Susceptible (<10%). Larval Package Test and Larval Immersion Test were applied to assess resistance levels on larvae; no significant difference was found between bioassays (p > 0.05). For this reason, both bioassays were combined in one figure.
