What is the Piezoelectric sprayer ?
  • The Piezoelectric sprayer is a new device for releasing semiochemicals that provides significant advantages over the passive substrates (i.e., filter paper, rubber septa, etc).

  • The Piezoelectric sprayer allows precise release of semiochemicals during the entire course of an experiment.

  • Release rate can be set to almost any value, i.e. pg/min, fg/min, etc.

  • The Piezoelectric sprayer can release a mixture of semiochemicals at constant ratios and rates.

  • The release rate of semiochemicals is not affected by factors such as the vapor pressures and mole percentages of the compounds, temperature, relative humidity, material surface area, and wind speed.

  • Can be used in the laboratory and field experiments.

  • Multiple Piezoelectric sprayer can be used to provide dynamic control over stimulus application.
Laboratories implemented the Piezoelectric sprayer in their experiments:
  • Unversity of California Riverside, Dept. of Entomology, Riverside, USA.
  • University of Ulm, Dept. of Experimental Ecology, Ulm, Germany
  • Lund University, Chemical Ecology group, Lund, Sweden.
  • Swedish University of Agriculture Sciences (SLU), Chemical Ecology group, Alnarp, Sweden.
  • Cornell University, Agriculture Experimental Station, Dept. Entomology, Geneva , NY, USA.
  • University of Alberta, Dept. of Biology, Edmonton, Canada.
  • Agriculture and Agri-Food, Vineland, Canada.
  • Agriculture and Agri-Food, Summerland, Canada.
  • Research Institute for Plant Protection, Wageningen, The Netherlands.
  • North Dakota State University, Department of Entomology, Fargo, USA.
