| description | Postharvest agricultural losses constitute a major food security risk. In contrast, postharvest protection is strongly linked with food safety. The present study aims to develop novel postharvest protection tools through a bioprospecting protocol utilizing edible essential oils (EOs) as grain coatings. For this purpose, six Mediterranean culinary plants were selected for evaluation. The EOs of juniper, <i>Juniperus phoenicea</i> L. (Pinales: Cupressaceae), marjoram, <i>Origanum majorana</i> L. (Lamiales: Lamiaceae), oregano, <i>Origanum vulgare</i> ssp. <i>hirtum</i> (Link) A.Terracc. (Lamiales: Lamiaceae), bay laurel, <i>Laurus nobilis</i> L. (Laurales: Lauraceae) and tarhan, <i>Echinophora tenuifolia</i> ssp. <i>sibthorpiana</i> (Guss.) Tutin (Apiales: Apiaceae) were retrieved through steam distillation, while lemon, <i>Citrus limon</i> (L.) Osbeck (Sapindales: Rutaceae) EO was retrieved through cold press extraction. All EOs were formulated to microemulsions (MEs) and applied uniformly as a coating on wheat against larvae and adults of <i>Tribolium castaneum</i> (Herbst) (Coleoptera: Tenebrionidae) and <i>Trogoderma granarium</i> Everts (Coleoptera: Dermestidae). All EO-based MEs have been evaluated for the first time as grain coatings. They caused moderate to high mortality to <i>T. castaneum</i> larvae (67.8–93.3% 14 days post-exposure) and <i>T. granarium</i> adults (70.0–87.8% after 7 days of exposure). <i>Citrus limon</i>, <i>O. majorana</i> and <i>E. tenuifolia</i> ssp. <i>sibthorpiana</i> EO-based MEs were the most efficient against <i>T. castaneum</i> larvae, by exhibiting 93.3%, 91.1% and 90.0% mortality 14 days post-exposure, respectively. <i>Origanum majorana</i>, <i>L. nobilis</i> and <i>J. phoenicea</i> EO-based MEs were the most efficient against <i>T. granarium</i> adults, exhibiting 87.8%, 84.4% and 83.3% mortality after 7 days of exposure, respectively. These results indicate that EO-based ME coating is a potent tool against the tested postharvest pests. |
