Article Synopsis
- A systems approach was created to replace traditional quarantine methods for treating Thaumatotibia leucotreta in South African citrus exports, involving pre and postharvest controls, postpacking inspections, and low-temperature exposure.
- Trials tested the effectiveness of seven cold temperatures (0-5°C) for 14 to 26 days, finding that temperatures of 0, 1, 2, and 3°C could achieve 100% mortality in the pest after specific durations.
- Efficacy varied significantly among different temperatures, with lower temperatures leading to higher mortality rates, suggesting that a combination of cold treatments and other preventive measures can be effective while minimizing fruit damage.
A systems approach was previously developed for mitigating phytosanitary risk of Thaumatotibia leucotreta (Meyrick) in citrus fruit exported from South Africa, as an alternative to a standalone cold disinfestation treatment. The present study first tested the original systems approach by applying it on a semicommercial scale in 10 Nova mandarin orchards. Fruit were inspected at points in the production, packing, and simulated shipping process, to assess performance of the systems approach.

It is an important pest of litchis and to a lesser extent macadamias. Litchis are exported to certain markets that consider C.
