Chemical Composition and Insecticidal Potential of Six Essential Oils from Morocco against Dactylopius opuntiae (Cockerell) under Field and Laboratory Conditions

The carmine cochineal Dactylopius opuntiae (Cockerell) is the major insect pest of the prickly-pear cactus Opuntia ficus-indica (L.) in Morocco. The present study investigated the insecticidal activities of six essential oils (EOs) against nymphs and adult femal...

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.Chaimae RamdaniKarim El FakhouriMohamed SbaghiRachid BouharroudRachid BoulamtatAbderrahim AasfarAbdelhalim MesfiouiMustapha El BouhssiniMDPI AGarticlewild cochinealessential oilsblack soaptoxicitychemical compoundcactus pearScienceQENInsects, Vol 12, Iss 1007, p 1007 (2021)
