Efforts to control the mite are essential to safeguarding the industry. The mite causes erineum galls (hairy, abnormal growths) to form on the leaves of the tree. Retreat each lychee tree identified as positive for Lychee Erinose Mite with approved sulfur‐based miticide seven (7) times after the onset of bud/leaf break unless directed by FDACS, DPI to stop treatment. But even lovely lychee trees are not pest free. Lychee trees produce delicious fruit, but they are also beautiful, majestic trees in their own right.

The project did find that oil dips could exacerbate surface fungi (rots) from about 10 days after treatment, predominately around the stalk end of fruit, but this problem wasn’t found with the flood spraying approach. The mites are invisible to the naked eye and live on the underside of the leaves amongst the erinose. As part of their work, the project team established a prototype roller conveyer incorporating an in‐line water spray, oil flood spray and post-oil water spray, which significantly reduced the count of live mites. Further, the oil treatment was assessed in combination with irradiation, with no adverse interaction between the two seen – and during the project, a commercial shipment of lychees treated using oil and irradiation successfully entered the US. This project ran from 2016 to 2018 to help address a potential barrier to the export of Australian lychees: the presence of common pest the lychee erinose mite (Aceria litchii). Though oil alone didn’t completely eliminate the pests, the addition of pressure washing before, and two minutes after, the oil application further reduced their incidence. The researchers found that paraffinic oil at three per cent concentration applied as a 30 second dip or flood spray reduced mites and other surface insects on fruit. The researchers investigated simple postharvest treatments to reliably remove the mite from fruit destined for markets including the US and New Zealand. DPI, in partnership with UF-IFAS has conducted extensive research which will guide the eradication process. (Nicky Redl - ABC Rural) Map Rockhampton 4700. - If a negative tree becomes positive for lychee erinose mite, the tree will receive the positive tree treatment process.

This program is funded through the Plant Pest and Disease Management and Disaster Prevention Program in partnership with the USDA-APHIS. “We have eradicated this pest twice before in 1958 and 1993, and we are confident in our methods to eradicate LEM again.”. This process includes checking all lychee trees within a half-mile radius of any new find for the presence of the mite and resurveying previous negative sites. The lychee erinose mite is a pest of lychee fruit trees. While lychees heading to these export destinations are subject to an irradiation protocol to eradicate target quarantine pests, the non-target erinose mite is able to withstand current irradiation rates – and higher rates could damage the fruit. To find out more information or to track the eradication process visit FDACS.gov/LEM or contact the FDACS-DPI Helpline at 888-397-1517. Lychee tree pests can cause problems for the homeowner, given the size of the tree. After identification and an initial survey, the department quarantined movement of any lychee plant, plant parts or fruit from Lee County to any other Florida destination due to the dense population of the mite in the county. It causes erineum galls, or hairy abnormal growths, to form on the leaves of the lychee tree. Without treatment, an infestation of mites can severely damage the tree, fruit and flowers. Lychee trees are susceptible to erinose mite but a simple remedy will have them producing fruit again in no time. Key research provider: The Queensland Department of Agriculture and Fisheries, Publication date: Thursday, April 4, 2019, Treatment for mites on lychee fruit prior to irradiation for improved market access (LY16002). Without treatment, an infestation of mites can severely damage the tree, fruit and flowers. LEM has been successfully eradicated twice in Florida, first in 1958 in Sarasota County and then in Miami-Dade County in 1993. Other trees in the area are being surveyed and monitored for the presence of this mite. LY16002 Disinfestation of mites on lychee in conjunction with radiation for improved market access of lychee to the USA 6 Introduction Australian lychee (Litchi chinensis) was granted market access to the USA in 2013 under a trial protocol that included irradiation as the disinfestation treatment.
