Linalool is a natural scent, found in essential oils (EOs) of several plants. It is widely used as a fragrant, also possessing toxic, oviposition deterrent, and repellent properties against many insect species. Ceratitis capitata (medfly) is one of the most notorious insect pests for international fresh fruit production. Despite the available information on the repellent effects of EOs on herbivorous insects, possible ovipositional deterrent effects of linalool against C. capitata remain unknown.
OBJECTIVES AND RESULTS:
We tested whether different linalool concentrations, application methods on fruit hosts and time since application elicited oviposition-deterrence on medfly, from bitter oranges, apples and nectarines, under constant laboratory conditions. We also tested possible repellent properties of linalool on adult medflies in field conditions. Females drilled less oviposition stings and deposited fewer eggs per fruit in all linalool-treated hosts. Spraying and topical-droplet application were the most efficient methods on bitter oranges, although spraying was the least effective one in apples. Bitter oranges and nectarines that were offered to females immediately after exposure to linalool received more oviposition stings and eggs than those offered three days post-exposure to linalool solutions. Conversely, apples tested three days following linalool application received significantly more oviposition stings and eggs than those tested immediately and one day post exposure. More adults in total and more females were captured in traps located on untreated-control than on linalool treated trees, especially in citrus hosts.
Linalool has a potential future use in environmental friendly control strategies against C. capitata. This article is protected by copyright. All rights reserved.

Linalool is a fragrance widely used in cosmetics and household products. Until recently, contact allergy to linalool was considered rare because positive patch tests to it were infrequently observed. In recent years, however, it has been demonstrated that exposure of linalool to oxygen (air) results in formation of a number of oxidation products, of which the hydroperoxides have a far stronger sensitizing potency than the pure compound. By routine testing of patients suspected of having contact dermatitis with hydroperoxides of linalool, high frequencies of positive reactions were found, indicating these chemicals are important fragrance allergens. It should be realized, however, that a number of “positive” reactions may well be false-positive, irritant responses.

Linalool is a main component in different naturally derived essential oils, and widely used in household, personal care, food and therapeutic formulations. However, the application is limited due to its high volatility and low stability. In this study, an effective encapsulation with high loading ratio was built up together with thermal-redox dual responsiveness and controlled release properties. The emulsified linalool droplets were modified with carbon-carbon double bonds, followed by the precipitation polymerization with thermal sensitive monomer, N-vinyl caprolactam. The average size and the loading ratio of the prepared linalool capsules were 1.4 μm and 50.41 wt%. The linalool capsules exhibited thermal-redox dual responsive properties and the antioxidant-antibacterial performance. Especially, responding to the stimuli mimicking practical circumstance, the synthesized capsules presented excellent bacteria inhibiting effect. This work may open a new path for fragrance and essential oil encapsulation, enlarging them as the green biological antibacterial agents in different applications.
