Abstract:

Acetaldehyde (Aa), a volatile compound produced naturally in small quantities by fruits and other plant organs, was found to be toxic to Frankliniella occidentalis (Pergande) on strawberries. Fumigation of field-infested strawberries with 2.0% Aa for 4 h at 21°C caused 100% mortality in thrips and drying of the calyx. Fumigation with Aa in atmospheres that contained 50% CO2 or 1.0% O2 eliminated this injury to the calyx. Fumigation with Aa at concentrations as low as 1.5% in combination with 1.0% O2 caused 100% kill. Concentrations of 1.5 or 2.0% Aa also reduced decay of the strawberries by more than 50%. Thus, Aa has potential as a fumigant for postharvest control of the western flower thrips on strawberries shipped to Japan and other foreign countries with strict quarantines against this insect.
