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 by applying it on semicommercial scale 10 Nova mandarin orchards. Fruit were inspected at points production, packing, and simulated shipping process, assess performance approach. Additional data obtained 17 Valencia orange...
A systems approach was developed as an alternative to a standalone quarantine disinfestation treatment for Thaumatotibia leucotreta in citrus fruit exported from South Africa. The consists of three measures: pre and postharvest controls measurements, postpacking inspection, exposure low temperatures. Different cold conditions with range efficacy levels can be used this last measure. series trials reported here evaluated the seven temperatures ranging 0 5°C durations 14 d 26 d. Mortality most...
The use of protective netting is becoming an increasingly popular practice in the citrus industry South Africa. However, data on its effects biotic factors, particularly insect pests, are limited. This study focused effect nets have key pests Eastern Cape province. Orchards under and open orchards, similar cultivars, ages management practices, were monitored at several sites over two seasons for pest infestation damage. Weekly monitoring was conducted Thaumatotibia leucotreta infestation....
The use of protective netting is becoming an increasingly popular practice in the citrus industry South Africa. However, data on its effects biotic factors, particularly insect pests, are limited. This study focused effect nets have key pests Eastern Cape Province. Orchards under and open orchards, similar cultivars, ages (all mature) otherwise identical management practices, were monitored at several sites over two seasons for pest infestation damage. Nets erected start first season. Weekly...
False codling moth (FCM), Thaumatotibia leucotreta (Meyr) (Lepidoptera: Tortricidae) is endemic to southern Africa and an important pest in a number of fruit industries, most notably, the South African citrus industry, as it considered phytosanitary by many export destinations. Citrus packhouses have reported lower infestation T. leucotreta, from organically farmed orchards than conventionally orchards. Therefore, field surveys were conducted determine if was on organic farms compare natural...
The litchi moth, Cryptophlebia peltastica (Meyrick) (Lepidoptera: Tortricidae), is endemic to sub-Saharan Africa and certain Indian Ocean islands. It an important pest of litchis a lesser extent macadamias. Litchis are exported markets that consider C. as phytosanitary pest. Consequently, effective postharvest treatment required. This study sought develop cold disinfestation for this purpose. First, it was established the fifth instar most cold-tolerant larval stage, only which there still...
