The study was carried out during 2015-2016 in the Biological Control Researcher Center, Faculty of Agriculture, Damascus University.

It aimed to determine the changes of volatile emissions from almond leaves infested with Aporia crataegi (L.) (Lepidoptera: Pieridae) compared to the un-infested ones.

The study revealed 42 new compounds emitted from infested almonds.

The most important compounds were: (CIS-3- Hexenyl Acetate, CIS-3-Hexenyl Acetate, Limonene, Z -β-Ocimene, Linalool or allo-Ocimenol, Nonanal, (E)-4,8-Dimethyl-1,3,7-nonatriene, CIS (Z)-3-Hexenyl butyrate, Trans-2-hexenyl butyrate, 2-hexenyl tiglate, (E)-beta-farnesene, trans- α –Bergamotene, (E,E)-α-Farnesene, Limonene-6-ol, Methyl salicylate, isopropyl palmitate), that showed ability to attract parasitoids.
