The Toxicity Testing of a Susceptible Strain of Tetranychus urticae to Spirodiclofen 240 g/L SC
[Aims] In order to forecast and monitor the resistance, log-dose probit-mortality data of spirodiclofen 240 g/L SC to the susceptible strain of Tetranychus urticae Koch in different stages was established. [Methods] The toxicity of spirodiclofen 240 g/L SC against Tetranychus urticae was tested using both leaf disk dip and leaf residue methods. [Results] The estimated LC50 for the eggs and larvaes were 3.1886 and 15.1252 mg/L, respectively. LC50 of eggs laid by treated female adults was 13.2495 mg/L. [Conclusions] Based on results of this study, eggs were more susceptible to spirodiclofen 240 g/L SC than larvaes. The compound colud control significantly reproductive capacity of female adults.
