Abstract
Tetranychus urticae Koch is the most harmful pest to 
many plants in the globe. This previously completed work may 
offer fresh perspectives on the use of Thuja orientalis, a plant 
extract, as environmentally beneficial acaricide. The 
effectiveness of various quantities of plant extract from T. 
orientalis against adult females of the two-spotted spider mite T. 
urticae, with LC50 values of 8.35, 6.310, and 4.48 after one day, 
two days, and three days, respectively. In addition to the 
abamectin (vertimec 1.8 EC) acaricide's acaricidal efficacy at 
various concentrations, where the LC50 values were 1.02, 2.74, 
and 1.65 after one day, two days, and three days, respectively. 
Furthermore, the adult fecundity, repellency, and hatchability of 
T. orientalis plant extract and vertimec varied substantially with 
concentration. The findings of this study suggested that the plant 
extract of T. orientalis might be used as a bio acaricide compared 
with vertimec to control spider mites.
