Promising Results in USDA Disinfestation Trials Using RipeLockers to Control Spotted-Wing Drosophila

Seattle, WA, September 6, 2022 – RipeLocker broadens the use of its innovative system for senescence control and decay suppressant of perishables, to eliminate invasive fruit flies without the application of postharvest fumigants such as methyl bromide or required cold treatments at the port of loading.

Disinfestation trials are being conducted by RipeLocker’s research partners in the United States and Australia to control these pests and eliminate their development and reproduction while being stored inside the RipeLockers.

The USDA has been searching for a chemical-free alternative to reduce the time highly perishable items must remain at the port of loading for quarantine before being exported.  Successful trial results have been seen at the USDA ARS research lab in Parlier, CA testing the efficacy of RipeLocker’s hypobaric system as a solution for control of Spotted-Wing Drosophila (SWD) on blueberries.

Dr. Spencer Walse, Research Chemist in USDA ARS’s Commodity Protection and Quality Research Unit exclaims, “This low-pressure vacuum technology is a game-changer in the fight against SWD infesting fresh fruit. We’ve achieved 100% kill of all life stages of SWD when infested blueberries were stored in the RipeLockers for just 6 days.”

“Six days might not sound like a long time but for highly perishable items like blueberries, table grapes, and cherries, adding six days to the time it takes to get the fruit to market is an eternity,” said George Lobisser, Co-Founder & CEO of RipeLocker.

Ultimately these results could allow for a grower/packer/shipper to immediately ship their fruit to the port of entry without the extra 6-day cold treatment inside the packing house or at the port if this fruit is being transported via the RipeLocker.

To further test RipeLocker’s technology overseas, New South Wales Primary Industries fruit fly research laboratory in Australia has received the RipeLocker system and will soon conduct fruit fly postharvest disinfestation trials.

 

The Technology Behind RipeLocker Chambers

RipeLocker chambers offer a unique, patented system to manage the atmospheric pressure, and gas composition (oxygen and CO2) within the chambers to extend the life of fresh produce and flowers. Based on the specific needs of each type of fresh produce or flower, RipeLocker tailors operating parameters, such as internal pressure, oxygen, and CO2 levels, to optimize longevity and freshness. The system continuously reports operating data enabling real-time decision-making to senescence and decay.

RipeLocker designed its pallet-sized chambers so that they can easily be deployed and used in the existing cold chain. Produced using novel materials and highly scalable manufacturing processes, the RipeLocker chamber is the first solution that can be delivered cost-effectively in mass volume. RipeLocker has patents on both chamber design and method of operation.

About RipeLocker

RipeLocker has patented a radical innovation designed to disrupt existing postharvest technologies and processes of preserving the life and freshness of perishables. The company’s dynamic, low-atmosphere chambers are used for storing and shipping fresh produce and flowers to extend their after-harvest life by weeks, often months. When RipeLocker chambers are used, shippers and retailers reduce food loss and consumers benefit from a better taste and longer shelf-life.  RipeLocker, founded in 2016 and based in Seattle, WA, US, is a science-based and data-driven company. It continues to conduct efficacy trials of its RipeLocker chambers for a variety of different crops with the largest growers in the world. For more information, go to www.ripelocker.com.
