PULLMAN, Wash. – No insect drew more gasps than the parasitoid wasp during a field trip of undergraduate entomology students at Washington State University’s organic farm. But it wasn’t the wasp’s sting that made some step away with their eyes wide. It was the insect’s bizarre attack on an aphid on the underside of a just-picked kale leaf.

Replacing chemical fumigation of fruit with low pressure

PULLMAN – Fruit consumers and growers will be delighted if Shaojin Wang, a WSU assistant research professor of biological systems engineering, can achieve his research goal. Wang is pursuing a method that could replace the chemical fumigation of apples and cherries grown in Washington with simple low-pressure treatments.

Low-pressure storage technology changes the normal composition of air, creating an environment inhospitable to pests that would otherwise attack the crop. While pests are controlled, fruit is kept fresh without over-ripening or senescing.

Wang is working on a technically effective and environmentally sound process to disinfest cherries and apples using low-pressure methods.
