The twospotted spider mite, Tetranychus urticae (Koch), is a significant economic pest of peanut, Arachis hypogaea L. In two to three days, a single adult, female T. urticae can oviposit an average of 38 eggs. Many acaricides are effective in managing the active forms of T. urticae, while not much is known about their ovicidal properties. Three acaricides were evaluated under laboratory conditions to determine their efficacy against T. urticae eggs. The three acaricides include fenpropathrin, propargite, and etoxozole, with multiple rates per acaricide. The acaricides were applied to T. urticae eggs and a hatch rate was determined over the course of ten days.
