Development of regulatory treatments for two recent invasive tortricids in California: Light brown apple moth and European grapevine moth

Unfortunately, when new invasive pests are detected and quarantine restrictions are put into place, treatments that will allow the movement of restricted commodities out of the quarantine areas are often lacking. This project was developed to establish post harvest treatments for fruit commodities to allow export from areas in California currently under quarantine for the European grapevine moth, Lobesia botrana and light brown apple moth, Epiphyas postvittana. We report on experiments to verify the current methyl bromide treatment schedules and evaluate gaseous phosphine and other alternatives to methyl bromide for use in post harvest treatment of fruit.
