Greek Pinus essential oils: larvicidal activity and repellency against Aedes albopictus (Diptera: Culicidae)
Parasitology Research 114 (2), 583-592
Abstract: The needle volatiles metabolites of seven Pinus spp.: Pinus nigra (3 samples), Pinus stankewiczii, Pinus brutia, Pinus halepensis, Pinus canariensis, Pinus pinaster and Pinus strobus from Greece were determined by gas chromatography and gas chromatography–mass spectrometry. P. nigra and P. canariensis essential oils were dominated by alpha-pinene (24.9–28.9 % and 15 %, respectively) and germacrene D (20.3–31.9 % and 55.8 %, respectively), whereas P. brutia and P. strobus by alpha-pinene (20.6 % and 31.4 %, respectively) and ß-pinene (31.7 % and 33.6 %, respectively). P. halepensis and P. pinaster oils were characterized by ß-caryophyllene (28.5 % and 22.5 %, respectively). Finally, ß-pinene (31.4 %), germacrene D (23.3 %) and alpha-pinene (17.5 %) were the most abundant compounds in the needle oil of P. stankewiczii. Additionally the larvicidal and repellent properties of their essential oils were evaluated against Aedes albopictus, a mosquito of great ecological and medical importance. The results of bioassays revealed that repellent abilities of the tested essential oils were more potent than their larvicidal activities. The essential oils of P. brutia, P. halepensis and P. stankewiczii presented considerable larvicidal activity (LC50 values 67.04 mgL-1 and 70.21 mgL-1, respectively), while the others were weak to inactive against larvae. The essential oils of P. halepensis, P. brutia, and P. stankewiczii presented a high repellent activity, even at the dose of 0.2 μL cm-2, while in the dose of 0.4 μL cm-2, almost all the tested EOs displayed protection against the mosquito.
