“…In general, in South America most records of M. sojae have been reported in Argentina (Saluso, 2020; Trossero et al, 2020; Pozebon et al, 2021; Vera et al, 2021), followed by the states of Santa Catarina and Rio Grande do Sul in Brazil (Guedes et al, 2015; Arnemann et al, 2016a,b; Czepak et al, 2018; Pozebon et al, 2021), then Alto Paraná in Paraguay (Guedes et al, 2017), and finally in Santa Cruz, Bolivia (Vitorio et al, 2019) (Table 3).…”

“…In South America, the first record of M. sojae was in Brazil and its occurrence has been reported from the 1980s (Gassen et al, 1985) to the present (Guedes et al, 2015; Arnemann et al, 2016a; Czepak et al, 2018). Recently, the species was also confirmed in Paraguay (Guedes et al, 2017) and Bolivia (Vitorio et al, 2019). In these countries, M. sojae was detected causing damage on soybean crops.…”

The Asian soybean stem borer Melanagromyza sojae (Zehntner) (Diptera: Agromyzidae) represents a threat to soybean and chickpea crops in South America. It is known that in the region its population has increased, in part, due to the difficulty in its agronomic management. This is due to the lack of knowledge regarding its biology and the environments that are favorable for its establishment. In this study, we provide a comprehensive database of records of M. sojae, as well as an updated list of its host plants from field surveys, bibliographic review, and online databases. We estimated the suitability and potential distribution of the pest considering environmental information from remote sensors and bioclimatic variables and contrasted these against land‐use cover across South America. In Argentina, M. sojae was found developing on Tithonia tubaeformis (Jacq.) Cass. (Asteraceae), surviving in chickpeas and volunteer soybeans that were affected by winter frost. The most informative models and highest suitability were predicted from vegetation indices and bioclimatic variables, and coincided with sites having a high proportion of arable land. Regarding climate, the greatest suitability occurred in eastern South America, including the southern states of Brazil and Paraguay, where the final models recovered the current known distribution of the species on the continent. However, its extension may be even greater than predicted, due to the wide distribution range of its hosts. This characterization of suitability for M. sojae could be a useful resource to anticipate the regions that are most favorable for its presence and supports the need to consider the distribution of crops and host plants that could act as natural reservoirs to identify sites and streamline efforts to reduce the incidence of the pest.

“…Although individuals belonging to the genus Melanagromyza were previously recorded in soybeans fields in Brazil in 1983 (Gassen & Schneider, 1985) and 2009 (Link et al, 2009), the presence of M. sojae was only confirmed in the country in 2015 based on specimens collected in the states of Santa Catarina and Rio Grande do Sul, southern Brazil (Anermann et al, 2016). Subsequently, M. sojae was found in the Brazilian Cerrado, in the state of Goiás (Czepak et al, 2018), and in Paraguay (Guedes et al, 2017), Bolivia (Vitorio et al, 2019), and Argentina (Vera et al, 2021), indicating the potential of this species spreading to the major soybean‐producing areas in South America.…”

The soybean stem fly, Melanagromyza sojae (Zehntner) (Diptera: Agromyzidae), is an example of an insect pest with a restricted distribution that in the last few decades has been spreading to regions beyond its native range and causing economic losses. We evaluated whether M. sojae shifted its niche during biological invasion and used ecological niche models to estimate its global distribution under current and future climate conditions. In addition, we assessed whether the soybean stem fly represents a risk for major soybean‐producing countries, using Brazil as an example. Our analyses suggest that M. sojae has expanded its niche to new environments. Suitable habitats were predicted in all continents, including regions where this species has not yet been reported. Several soybean‐producing countries and all Brazilian growing areas are within the suitable ranges estimated for M. sojae. Also, most areas estimated as suitable under current climate conditions will remain so until at least 2080. These findings are important for invasion risk assessments aiming to prevent the spread of this species to major soybean‐producing areas.

“…Soybean stem fly, Melanagromyza sojae Zehntner (Diptera: Agromyzidae), is native to eastern Asia and was recently detected in South America in 2015 (Arnemann et al, 2016), but it is suspected to have been present in southern Brazil since the 1980s (Gassen & Schneider, 1985). Since its detection in Brazil, M. sojae has spread across the South American soybean belt, reaching Paraguay (Guedes et al, 2017), Bolivia (Vitorio et al, 2019) and Argentina (Trossero et al, 2020). In Southern Brazil, outbreaks of M. sojae have been repeatedly observed on late-season soybeans, which are planted after maize (Zea mays L.) harvest beginning in late December (Folmann et al, 2017;Pozebon et al, 2020).…”

Soybean stem fly, Melanagromyza sojae Zehntner (Diptera: Agromyzidae), is an important soybean (Glycine max) pest in Eastern Asia that has recently colonized South America. The region colonized by M. sojae includes Brazil and several other major soybean growing countries. Management strategies for this pest remain largely undeveloped due to lack of information regarding its potential to injury soybeans. The objective of this study was to quantify soybean yield reduction caused by M. sojae injury. One experiment was carried out during two summer crop seasons (2020 and 2021) at Santa Maria, RS state, Brazil. Soybean was planted during late-season to ensure that high pressure of M. sojae adults were present in the fields. The number of seeds, 1,000-seed weight, seed yield and number of pods were quantified for the lower, middle and upper canopy, and plant height was compared to the amount of stem injured to determine percentage of injured stem. Each 1% of injured stem in the lower, middle and upper canopy segments significantly reduced the number of seeds per plant, 1,000-seed weight, and yield. Across all canopy segments, yield reduction reached 0.9 g per plant for every 1% of injured stem. Treatments where insecticide applications started during the vegetative phase presented the lowest damage by M. sojae. These data suggest that M. sojae is an economically important herbivore of soybeans under Brazilian growing conditions and highlight the need to develop efficient and sustainable management strategies for this pest.
