Chemical Composition and Insecticidal Potential of Six Essential Oils from Morocco against <i>Dactylopius opuntiae</i> (Cockerell) under Field and Laboratory Conditions
The carmine cochineal <i>Dactylopius opuntiae</i> (Cockerell) is the major insect pest of the prickly-pear cactus <i>Opuntia ficus-indica</i> (L.) in Morocco. The present study investigated the insecticidal activities of six essential oils (EOs) against nymphs and adult femal...

| description | The carmine cochineal <i>Dactylopius opuntiae</i> (Cockerell) is the major insect pest of the prickly-pear cactus <i>Opuntia ficus-indica</i> (L.) in Morocco. The present study investigated the insecticidal activities of six essential oils (EOs) against nymphs and adult females of <i>D. opuntiae</i> applied singly or in combination with a detergent under laboratory and field conditions. Under laboratory conditions, <i>M. pulegium</i> and <i>O. vulgare</i> L. essential oils showed a high level of insecticidal activity at 5%, with 98% and 92% females’ mortality, respectively, 5 days after treatments. The <i>M. pulegium</i> and <i>O. vulgaris</i> oils at 5% applied in combination with black soap at (60 g/L) induced the highest toxic activity on adult females, 100% and 96% at 5 days after treatments, respectively. Under field conditions, <i>M. pulegium</i> and <i>O. vulgare</i> oils at 5% in combination with black soap (60 g/L) showed the highest adult female mortalities with 96.33 and 92.56%, respectively, 7 days after the first application. The double application of <i>M. pulegium</i> oil at 5% significantly increased the mortality of adult females up to 91%, 5 days after the second spray. GC-MS analysis revealed that the most abundant constituent of <i>M. pulegium</i> and <i>O. vulgare</i> oils was pulegone (84.69%) and durenol (76.53%), respectively. These findings showed that the use of <i>M. pulegium</i> and <i>O. vulgare</i> in combination with black soap or in double sprays could be incorporated in the management package for the control of the wild cochineal <i>D. opuntiae</i>, as a safe and natural alternative to chemical insecticides. |
