| Abstract | ||||
| In the present study, insecticidal Activity of essential oils (lemon grass Cymbopogon citratus, thyme Thymus vulgaris and geranium Pelargonium graveolens) and silver nanoparticles (AgNPs) synthesized by using tested essential oils were evaluated against female of P. solenopsis Tinsley. At high concentration (40µl/l), the percentages of p. solenopsis mortality recorded 100, 100 & 86.70%, for thyme, lemon grass and geranium EOs, while it recorded 100, 90 and 83.3 % at (400ppm) of AgNPs-thyme, AgNPs-lemon grass, and AgNPs-geranium after 72hrs of treatment. All essential oils and AgNPs were proved to be very toxic to female of p. solenopsis. However, thyme essential oil and AgNPs-thyme recorded the highest mortality percentage with LC50 = 8.094 μl/l & 86.645 ppm, respectively, followed by lemon grass (bulk & AgNPs- lemon grass oil) and geranium oil (bulk & with AgNPs- geranium oil). | ||||
