Bactrocera dorsalis (oriental fruit fly).

Abstract

Abstract Bactrocera dorsalis is a highly invasive species. Native to Asia, Oriental fruit fly is now found in at least 65 countries, including parts of America and Oceania, and most of continental Africa (sub-Saharan countries). The potential risk of its introduction to a new area is facilitated by increasing international tourism and trade, and is influenced by changes in climate and land use. After introduction, it can easily disperse as it has a high reproductive potential, high biotic potential (short life cycle, up to 10 generations of offspring per year depending on temperature), a rapid dispersal ability and a broad host range. The economic impact would result primarily from the loss of the export markets and the costly requirement of quarantine restrictions and eradication measures. Furthermore, its establishment would have a serious impact on the environment, following the initiation of chemical and/or biological control programmes. Invasive B. dorsalis has been shown to be highly competitive with native fruit flies where it has established, quickly becoming the dominant fruit fly pest (Duyck et al., 2004; Vargas et al., 2007; Vayssières et al., 2015). Oriental fruit fly is of quarantine significance to EPPO (European Plant Protection Organization), APPPC (Asia and Pacific Plant Protection Commission), COSAV (Comité de Sanidad Vegetal del Cono Sur), CPPC (Caribbean Plant Protection Commission), IAPSC (Inter-African Phytosanitary Council) and OIRSA (Organismo Internacional Regional de Sanidad Agropecuaria) countries.
