| Abstract | ||
| Laboratory studies were conducted to evaluate the toxicity of seven systemic graminicides in addition to kelthane as a reference acaricide on the Tetpanychus urfica and T. cinnabarinus and their effects on the biometrics of T. urtica. All the tested graminicides were toxic to T. cinnabarinus than to T. uriica Both LC50 and LC95 values were lower on T. cinnabarinus than on T. urtica. The most toxic compound was Propequizafop (T7). Biological aspects of T.urtica such as the adult female longevity, oviposition period, number of deposited eggs and egg hatchability were significantly reduced by Propequizafop (T7) followed by Fluazifop-butyl. | ||
