n African Entomology - The host status of lemons for the false codling moth, (Meyrick) (Lepidoptera : Tortricidae) with particular reference to export protocols




The South African citrus industry is dependent on export of fresh fruit to many markets around the world, with approximately 70% of South Africa's citrus crop being exported (CGA 2013). The false codling moth, (Meyrick) (Lepidoptera : Tortricidae), is recorded as a pest of citrus fruit in southern Africa (Newton 1998; Grout & Moore 2015). As a result of its endemism to sub-Saharan Africa (Moore 2002), certain export markets of importance for the South African citrus industry, such as Peoples Republic of China, U.S.A. and South Korea, regulate it as a quarantine pest.Control of the pest in the field can be highly effective, using a suite of integrated control options, applied with diligent management (Moore & Hattingh 2012). These can succeed in reducing infestation by 97% or more (Moore 2015). Such an integrated system, using the sterile insect technique as the mainstay of the programme, has succeeded in reducing moth catches by 99%, fruit infestation by 96% and export rejections by 89% in the Western Cape Province of South Africa, since the inception of the programme in 2007 (Barnes 2015).
