Project Type: Specific Cooperative Agreement
Start Date: Jun 1, 2012
End Date: May 31, 2015
1. Develop a media type of "patch or rod" containing embedded basil oil and determine the rate of diffusion during storage, evaluating the effect of the release of oil aroma on the mortality rate, feeding rate and repellency to insects. An insect such as Sitophilus oryzae (rice weevil) will be used because it is an important a contaminant of cereals and easy to raise in the laboratory. 2. Characterize the physicochemical properties of the broadcast medium and evaluate the rate of diffusion of active compounds during storage.
The physical matrix or patch will be developed by polymer engineers at the University of Quebec. Various concentrations of basil or other essential oils will be embedded in the polymer matrix. The patch emitting basil oil aroma in various concentrations will be tested for their effects on rice weevil mortality, repellency and feeding in a series of bioassays.
