Current Research-Vacuum
headline bar

It is possible to use low pressure environments to disinfest products of insect infestations.   The development of gas-tight, flexible containers for bulk product storage has made vacuum treatment more practical.   We are developing vacuum treatment schedules for dried fruit and nuts pests and testing the method in the field.

 

We are also working with our collaborators at Washington State University to develop low pressure - low temperature treatments for codling moth in fresh tree fruits.
