“…In natural areas where environmental conditions are similar to those observed in its original area in Africa, Z. indianus dominates drosophilid assemblages during the wet season (Tidon et al, 2003). It also predominates in fig plantations: among 125,00 drosophilids captured in São Paulo State, 83,339 were identified as Z. indianus (Roque et al, 2017). This species is highly adaptable (Mata et al, 2010) and deserves to be monitored.…”

Thirteen species of drosophilid exotic to the Neotropical Region are recorded in Brazil, and some of them are highly invasive and threaten significantly fruit cultures. We provide an illustrated key for identifying these species, and briefly discuss their taxonomic status, distribution, and occurrence in the Neotropics. The key should not only support newcomers to the study of Drosophila but also facilitate their identification by those interested in insects associated with cultivated areas.

“…Z. indianus is a generalist and uses multiple hosts in its original range in Africa (Yassin and David 2010) and both crops and native fruits where it has been introduced (Leão and Tidon 2004, van der Linde et al 2006). In many of these hosts across the globe, Z. indianus are found at high numbers compared to other drosophilids (Silva et al 2005, Roque et al 2017, Pfeiffer et al 2019). Z. indianus is primarily a secondary pest that largely infests damaged or decaying fruit, except in figs, but could become a pest of other crops (Bernardi et al 2017, Pfeiffer et al 2019).…”

The African fig fly, Zaprionus indianus (Gupta), has spread globally from its native range in tropical Africa, becoming an invasive crop pest in select areas such as Brazil. Z. indianus was first reported in the United States in 2005 and has since been documented as far north as Canada. As a tropical species, Z. indianus is expected to have low cold tolerance, likely limiting its ability to persist at northern latitudes. In North America, the geographic regions where Z. indianus can thrive and seasonal fluctuations in its abundance are not well understood. The purpose of this study was to characterize the temporal and spatial variation in Z. indianus abundance to better understand its invasion of the eastern United States. We sampled drosophilid communities over the growing season at two orchards in Virginia from 2020-2022 and several locations along the East Coast during the fall of 2022. Virginia abundance curves showed similar seasonal dynamics across years with individuals first detected around July and becoming absent around December. Massachusetts was the northernmost population and no Z. indianus were detected in Maine. Variation in Z. indianus relative abundance was high between nearby orchards and across different fruits within orchards but was not correlated with latitude. Fitness of wild-caught females decreased later in the season and at higher latitudes. The patterns of Z. indianus abundance shown here demonstrate an apparent susceptibility to cold and highlight a need for systematic sampling to accurately characterize the range and spread of Z. indianus.

“…In Africa, Z. indianus has been reported to use more than 70 host species in over 30 families ( Lachaise and Tsacas 1983 , Yassin and David 2010 ) plus additional species where it has been introduced ( Leão and Tidon 2004 , Van der Linde et al 2006 ). In many hosts, Z. indianus are found in high numbers compared to other drosophilids ( Silva et al 2005 , Roque et al 2017 , Pfeiffer et al 2019 ). Although Z. indianus is primarily a secondary pest that relies on damaged fruits, the possibility exists of unaided infestation in ripened peaches, strawberries, nectarines, plums, and grapes ( Joshi et al 2014 , Bernardi et al 2017 , Pfeiffer et al 2019 ).…”

The African fig fly, Zaprionus indianus (Gupta), is a generalist fruit fly that typically breeds in decaying fruits from over 70 plant species. The species has spread globally from its native range in tropical Africa, becoming an invasive pest on ripening figs in Brazil. First reported in the United States in 2005 in Florida, Z. indianus has since been documented as far north as Canada and is hypothesized to recolonize northwards from southern refugia each year. We sampled drosophilid communities over the growing season at 2 orchards in Virginia from 2020 to 2022 and 11 orchards along the East Coast during the fall of 2022 to quantify the abundance of Z. indianus relative to other drosophilids across locations, seasons, and fruit crops. Massachusetts had the northernmost population, with no Z. indianus detected in Maine and no correlation between latitude and relative abundance. Variation in Z. indianus relative abundance was high between nearby orchards and abundance was higher on peaches relative to apples within orchards. Comparisons of seasonal abundance curves between 2 Virginia orchards showed similar dynamics across years with individuals first detected around July and becoming absent around December, with peaks in late summer and mid-fall. The variation in seasonal and latitudinal abundance shown here highlights a need for broader sampling to accurately characterize the range, spread, and environmental tolerances of Z. indianus in North America.
