“…First introductions of G. a nis were in 1926 to Alexandria from a Corsican colony to arti cial waterbodies such as fountains and ponds (Welcomme, 1988;Amer, 2021). Introductions in the 1920s are also thought to have originated from Italy, Georgia, and United States (Walton et al, 2012).…”

Background. This review compiles and synthesises the existing information concerning non-native poecillid introductions to Africa. The recent upsurge in research on invasive poeciliids has revealed their widespread occurrence in Africa. Results. Within the 87 relevant articles, 74% reported on the presence Gambusia spp., 33% on P. reticulata, 19% on X. hellerii, 11% on X. maculatus, and 5% on other ornamental poeciliids. Overall, poeciliids have been introduced to 25 different countries in Africa, with Gambusia spp. being introduced to 16 countries and P. reticulata to 19 countries. Our results are representative of the current state of research on invasive poecilids in Africa. In particular there was a concentration of studies in South Africa, with limited research elsewhere. Current distribution data is relatively patchy, although widespread surveys of multiple river systems in Morocco and South Africa, confirmed widespread and abundant established poeciliid populations. The ecological impacts of invasive poeciliids in Africa remain understudied but evidence indicates deleterious effects on native fish, invertebrates, and amphibians, many of which are critically endangered or endemic species. Conclusion. An increased effort to monitor species composition in vulnerable waterbodies, especially in the many African countries where invasive poeciliids are reported should be completed and to reveal further established populations. Future research should prioritise quantifying the ecological impacts of invasive poeciliids in the field and identifying both vulnerable and resistant native ecosystems to guide future management decisions.

“…In Greece, alfalfa ( Medicago sativa L.) yields were suppressed 8% to 26% due to competition with S. elaeagnifolium (Travlos et al 2013). In Egypt, it caused a 30% reduction in barley ( Hordeum vulgare L.) yields (Amer 2021). In Tunisia, the weed was found in a very large area of irrigated crops (>2,300 ha) causing yield reductions in annual summer crops (Sayari et al 2021).…”

“…In northeastern Morocco, the spread was slow, because the weed was in uncultivated land, hence the pressure exerted under conditions of intense farming activity was not present (Chafik et al 2013). In Egypt, the spread has been rapid, and within 82 yr of first being reported, it has been detected 420 km west of the first site located near the eastern border of the country and has become established in cropland and perennial crops, across the railway network, along roadsides, and within abandoned sites (Amer 2021). In the El Alem region of Tunisia, where semiarid conditions prevail, S. elaeagnifolium covers about 40% to 60% of the soil in irrigated areas, occurring in scattered spots in 54% of surveyed zones and in uniform infestations in 30% of the zones (Sayari et al 2021).…”

The family Solanaceae lists about 1,400 species worldwide, of which 143 are considered weeds (Sheppard et al. 2006). The genus Solanum is the most numerous of the family Solanaceae. Solanum elaeagnifolium Cav. belongs to the clade Leptostemonum, commonly known as the “spiny solanum” clade. Solanum elaeagnifolium is native to northern Mexico and the American Southwest. A revision for the S. elaeagnifolium clade and analytic phytokeys are provided by Knapp et al. (2017). The silvery color of its leaves and their resemblance to the leaves of the olive tree (Elaeagnus) were the reasons for naming the species elaeagnifolium (Heap and Carter 1999). Nowadays, it is commonly known as silverleaf nightshade (Boyd et al. 1984). According to Krigas et al. (2021), in northern Greece S. elaeagnifolium is also called “Lernaean Hydra,” due to its intense regrowth after herbicide treatment. Solanum elaeagnifolium is known in South Africa as silverleaf bitter apple or Satansbos (Satan’s bush), indicating how harmful it is to the country (Wilson et al. 2013). In America and other parts of the world, it has received various names over the years, such as white horsenettle, bullnettle, tomatillo, meloncillo, and trompillo (Davis et al. 1945; Kwong et al. 2006). In Algeria, farmers call it echouka, which means thorn, because of the multiple spines on the stem (Adjim and Kazi Tani 2018). In South Korea, it received the name Eun-bit-kka-ma-jung, which is a combination of its silvery coloration and a common plant in the country (Hong et al. 2014).

“…Also, some African continent countries, including Mozambique, South Africa, Zimbabwe, Zambia, Botswana, Kenya and Congo, reported using indigenous vegetables [ 9 , 10 , 11 ]. Despite all these potentials, blackjack (Biden Pilosa) is underutilized in sub-Saharan Africa due to its classification as a weed or a wild plant [ 12 ], which creates a negative perception to the community concerning the consumption of wild or weed plants [ 13 , 14 ]. To date, no literature addresses consumer preferences for Biden pilosa for reported applications which is a serious omission in the literature .…”
