“…Additionally, overall yield losses due to SSF damage and ecological aspects of the insect in the New World remain poorly understood, including the potential existence of native or invasive beneficial insects that could target this pest, as reported by Beche et al (2018). Currently, containment and eradication measures would be expensive and unachievable, due to the M. sojae high reproduction rate and short generation time (four to five generations per year; Wang, 1979); moreover, early infestations are difficult to detect due to the small size of the flies, inconspicuous oviposition scars, and larval damage similar to that caused by other soybean stem-boring pests.…”

“…Future research directions on alternative control methods for SSF might include the breeding of resistant soybean varieties (see Wang and Gai, 2001) and biological control (e.g. by parasitoid Syntomopus parisii; see Beche et al, 2018), as well as detailed modeling of its potential economic impact in South American soybean fields. The findings from this study contribute to a better understanding of potential incursion pathways of M. sojae, and assist in the development of more efficient management strategies for this important agricultural pest.…”

This is the first scientific record of Melanagromyza sojae in Bolivia, confirmed through molecular characterization of the mtDNA COI gene. Commonly known as the soybean stem fly, M. sojae belongs to the family Agromyzidae and is a highly polyphagous pest, attacking several plant species of the Fabaceae family, such as soybeans and other beans. Previously reported in Brazil and Paraguay, the soybean stem fly presence was confirmed in soybean fields of the municipalities of Fernández Alonso, Cuatro Cañadas, Santa Cruz de la Sierra, Yapacani and Santa Rosa del Sara, which are located in Santa Cruz Department, Bolivia. This soybean stem fly detection in Bolivia will affect soybean crop practices in South America.

Highly diverse and rapidly spreading: Melanagromyza sojae threatens the soybean belt of South America

et al. 2021

The soybean stem fly, Melanagromyza sojae, an Asian native insect, has successfully established in Brazil, Argentina, Paraguay and Bolivia. These countries are among the lead global soybean producing nations, being collectively known as the soybean belt of South America. Infestation levels of M. sojae grow by the year, facilitated by the lack of efficient management strategies. Previous studies have revealed a high number of maternal lineages in M. sojae populations from Southern Brazil and Paraguay, but a comprehensive survey on genetic diversity combining samples from all countries within the South American soybean belt remains absent. We used the mitochondrial DNA cytochrome oxidase I partial gene (mtCOI) to characterize specimens of M. sojae collected in fourteen Brazilian sites and one Argentine site, and then combined our mtCOI data with previously published data from Australia, Bolivia, Paraguay, and other Brazilian sites, to investigate genetic diversity in this invasive agricultural pest species. Based on the molecular characterisation of the mtCOI gene, haplotypes Msoj-COI-01 and Msoj-COI-02 have the highest frequencies in the continent. The

“…Generally, the management strategies result in early sowing dates. However, biological control is done in some part of the world, as it was emphasized as an important remediation strategy to control pest outbreaks by many entomologists (Singh et al, 1991;Shanower et al, 1998;Tiwari et al, 2006;Beche et al 2018). The most abundant biological control is parasitism by the parasitoid wasp Syntomopus parisii (Hymenoptera: Pteromalidae) in Brazil and Paraguay, but this beneficial insect is not already mass cultured (Beche et al, 2018).…”

The soybean stem fly (SSF), Melanagromyza sojae (Zehntner) (Diptera: Agromyzidae), is highly polyphagous and attacks various host plant species in the family Fabaceae, such as soybean and other beans. A field survey was conducted during the 2016 and 2017 seasons at the Nubaria Agriculture Research Station, Egypt, to follow populations of the SSF on soybean cultures. The parasitoid Sphegigaster spp was identified and recorded for the first time as a solitary parasitoid on SSF pupa. The parasitoid's morphology was studied by using The scanning electron observations of the morphology confirms the genus of the parasitoid. The insect injurious stage of SSF on soybean plantations was larva that feeds inside the plant stem then convert to pupa during Jun.-Sept. (2016-2017). The level of SSF infestation was severe compared with insect pests orders Hemiptera and Lepidoptera. The infested plants by M. sojae and the level of parasitism (non-parasitized and parasitized SSF pupae) were estimated during 2016 and 2017 seasons. The results indicate that the exit hole of M. sojae is associated with the entry of the parasitoid into a pupa. The Parasitism percentages on SSF pupae by Sphegigaster parasitoid increased gradually up to 38.7% in August 2016, while it is 34.3% in August 2017. In September 2016 and 2017, respectively and then started to decrease in September where it was 16.7%, 22.2% in two successive seasons. Finally, the average of parasitism percentages on SSF pupae by their parasitoids Sphegigaster spp was 23.4% in 2016, while it is 26.7% in 2017. The Sphegigaster spp sex ratios were male biased, being respectively 52% (14 females and 15 males) in 2016 and 62% (12 females and 20 males) in 2017. The result point to the first record of the parasitoid Sphegigaster spp in Egypt on SSF pupae offers a promising opportunity for a biocontrol of soybean stem fly under local agronomic and climate conditions. Therefore, the presence of the parasitoids of M. sojae in Egypt was useful for the development of biocontrol methods to limit its impact on regional soybean production.
