Phytosanitary Irradiation

چکیده
Phytosanitary treatments disinfest traded commodities of potential quarantine pests. Phytosanitary irradiation (PI) treatments use ionizing radiation to accomplish this, and, since their international commercial debut in 2004, the use of this technology has increased by ~10% annually. Generic PI treatments (one dose is used for a group of pests and/or commodities, although not all have been tested for efficacy) are used in virtually all commercial PI treatments, and new generic PI doses are proposed, such as 300 Gy, for all insects except pupae and adult Lepidoptera (moths). Fresh fruits and vegetables tolerate PI better than any other broadly used treatment. Advances that would help facilitate the use of PI include streamlining the approval process, making the technology more accessible to potential users, lowering doses and broadening their coverage, and solving potential issues related to factors that might affect efficacy.

Potential increase in fruit fly (Diptera: Tephritidae) interceptions using ionizing irradiation phytosanitary treatments.
Irradiation postharvest phytosanitary treatments are used increasingly and show further promise because of advantages compared with other treatments. Its chief disadvantage is that, unlike all other commercially used treatments, it does not provide acute mortality, although it prevents insects from completing development or reproducing. The objective of this research was to determine to what ex...

BACKGROUND The objective of this study was to determine whether irradiation could serve as a suitable phytosanitary treatment alternative to methyl bromide (MB) fumigation for blueberries and sweet cherry and also to determine the effect of phytosanitary irradiation treatment on survival of Salmonella spp. and Listeria monocytogenes on these fruit. 'Bluecrop' blueberries (Vaccinium corymbosum) ...
متن کاملFactors affecting ionizing radiation phytosanitary treatments, and implications for research and generic treatments.
Phytosanitary irradiation (PI) treatments are promising measures to overcome quarantine barriers to trade and are currently used in several countries. Although PI has advantages compared with other treatments one disadvantage bedevils research, approval, and application: organisms may remain alive after importation. Although this does not preclude their use as a phytosanitary treatment, it does...
متن کاملModified Atmosphere Storage May Reduce Efficacy of Irradiation Phytosanitary Treatments
Ionizing irradiation is a phytosanitary treatment that is increasing in application. The effect of low-oxygen, modified atmosphere storage on irradiation efficacy has not been addressed until recently. Hypoxia for 18 hours before irradiation until a couple of hours after irradiation reduced efficacy to varying degrees as measured by adult development or reproduction for four insects studied. It...
متن کاملLow-dose Irradiation Phytosanitary Treatment against Mediterranean Fruit Fly (diptera: Tephritidae)
The Mediterranean fruit fly, Ceratitis capitata (Wiedemann), is one of the most important quarantine pests in the world. Host commodities shipped from infested parts of the world to non-infested parts that might be susceptible to infestation should undergo a phytosanitary measure to render negligible the risk of shipping viable flies. Ionizing irradiation is a promising phytosanitary treatment ...
