Linalool insect repellent

Linalool Insect repellent, predator attractant, pathogen resistance... 

Studies into the method of action of essential oils as insect repellents are currently underway that may further help in the development of new products. Recently, the results of an investigation were reported on the method of action of the acaricidal properties of Lavandula angustifolia Miller essential oil and of linalool (60), one of its main components, against Psoroptes cuniculi [195]. The study confirms the anti-mite properties of lavender essential oil and of linalool (60) by inhalation, indicating an additional route for possible use of these substances both for prophylactic and therapeutic purposes. Also, the method of action of the toxicity of citrus peel oils to several insect species has recently been investigated [196]. The results indicated that an efficient way to use citrus peel essential oils to control insects would be as a fumigant in relatively enclosed or air-tight systems. 

Other. Lavaudiu oil is sometimes used as a source of linalool and linalyl acetate. Lavender oil is sometimes used externally as an insect repellent (martindale). 

The sugarcane rootstalk borer weevil is attracted to aggregate by food, others of its kind, and by their frass.161 If the pheromones involved can be identified, they can be used in traps. Insects interact with the terpenes in plants in a variety of ways.162 The insect may find the host plant in this way, either to eat it, or to lay eggs in it. Terpenes such as pulegone (11.34),163 thujone, camphor, and citronellal repel insects (11.35). Linalool has been used as an insecticide on house plants. 

Repellencv. A number of other plant-derived terpenoids have been demonstrated to be repellent to various insects. Many compounds in this class have been proven to be attractants to certain insects (1). Limonene at 1 or 10 mg/box repelled the cockroaches, to the untreated box, in significantly (p<0.05) greater numbers than the 0.001 mg rate or the controls (4). Pulegone and linalool at the 10 mg/box rate repelled significantly more individuals than the 0.0001 mg rate or the controls. Myrcene and a-terpineol did not demonstrate any repellency. Natural pyrethrins were significantly different from the controls at the 0.1 mg/box rate.
