The Department of Agriculture, Land Reform and Rural Development (DALRRD) recently officially declared the presence of spotted wing drosophila (Drosophila suzukii) in South Africa.
A single male fly was first identified from a trap at Misgund in the Langkloof, Eastern Cape, in late 2023, after which grower organisation Berries ZA, in collaboration with Hortgro, deployed traps in most berry-growing regions in the country to monitor the situation.
Since then, spotted wing drosophila (SWD) had been caught in Tzaneen in Limpopo; Curry's Post in the KwaZulu-Natal Midlands; various locations in the Langkloof, which falls in the Eastern and Western Cape; and Barrydale, George, Montagu, Napier, Worcester, Wolseley, Riviersonderend, Hemel-en-Aarde, Villiersdorp, Paarl, Simondium, Stellenbosch and Somerset West in the Western Cape.
