Abstract

Abstract : Essential oils (EOs) from Schinus molle, Helichrysum gymnocephalum, Cedrelopsis grevei and Melaleuca viridiflora, four aromatic and medicinal plants, are commonly used in folk medicine. EOs were characterized by gas chromatography/mass spectrometry (GC/MS) and quantified by gas chromatography‐flame ionization detection (GC‐FID); then evaluated for their behavioral effects on adults of the green pea aphid Acyrthosiphon pisum (Harris ) using a Perspex four‐armed olfactometer in order to test the compatibility of their use as phytoinsecticides to control this insect pest. Our results showed that the EOs from the leaves of S . molle, M . viridiflora and C . grevei did not change aphids' behavior. However, S . molle fruits EO seemed to be attractive while H . gymnocephalum leaves EO exhibited repellency towards aphids at a dose of 10 μl. The major compounds in S . molle fruits EO were 6‐ epi ‐shyobunol (16.22%) andd ‐limonene (15.35%). While, in H . gymnocephalum leaves EO, 1, 8‐cineole was the main compound (47.4%). The difference in aphids' responses to these two EOs could be attributed to the differences in their compositions. Our findings suggest that these two EOs have potential applications for the integrated pest management of A . pisum (Harris ). Abstract :
