| Title : | EFFECT OF WARIONIA SAHARAE EXTRACTS ON THE TWO‐SPOTTED MITE TETRANYCHUS URTICAE (ACARI: TETRANYCHIDAE) |
| Abstract : | This study evaluated the acaricidal and repellent effects of Warionia saharae extract on the two-spotted spider mite, Tetranychus urticae. Using five ethanolic concentrations (50%, 25%, 12.5%, 6%, and 1% (v/v), designated as C1, C2, C3, C4, and C5, respectively), the extract's efficacy was tested on adult mites. The results showed a significant increase in mortality over time and with higher concentration. At 72 h, all concentrations achieved 86-100% mortality. The highest concentrations (C1 and C2) were particularly fast-acting, causing over 69% mortality within 24 h. The extract also exhibited a repellent effect at the higher concentrations. The calculated LC50 values were 37.99% at 48 hours and 41.89% at 72 h. These findings suggest that W. saharae extract is a potent natural alternative for controlling T. urticae. |
