First report of Bactrocera invadens in Botswana
In 2010, the presence of Bactrocera invadens (Diptera: Tephritidae – EPPO A1 List) was detected for the first time in Botswana. 42 specimens were caught in traps (baited with cuelure and methyl-eugenol) which were located in several farms of the Chobe district (north of Botswana) and also at the Kazungula ferry border post (Zambezi River, adjacent to the borders with Namibia and Zimbabwe). Phytosanitary measures were taken and included: 1) a delimiting survey; 2) eradication procedures; 3) tracing-back studies to identify the source of infestation and try to prevent any further re-infestation; 4) prohibition to move host fruits from delimited areas.
The pest status of Bactrocera invadens in Botswana is officially declared as: Transient, actionable, under surveillance.
