Research Article First record of soybean stem fly Melanagromyza sojae (Diptera: Agromyzidae) in Paraguay confirmed by molecular evidence.

Abstract

ABSTRACT. We provided the first scientific record of Melanagromyza sojae (Zehntner, 1900), through molecular characterization of partial mtDNA COI gene, that confirms the occurrence of this pest in Paraguay. Previously reported in Brazil, an outbreak of larvae of M. sojae known as the soybean stem fly (SSF) that belongs to the family Agromyzidae, was also noted in soybean fields from the Canindeyú, Alto Paraná and Itapúa Departments in Paraguay. This pest is highly polyphagous, attacking various host plant species from the family Fabaceae, such as soybean and other beans. The implications of SSF detection in 2 J.V.C. Guedes et al. Genetics and Molecular Research 16 (3): gmr16039707 Paraguay are discussed in relation to the current soybean cultivation practices from this agriculturally important South American region, including Brazil.

Research Article First record of the soybean stem fly <i>Melanagromyza</i> <i>sojae</i> (Diptera: Agromyzidae) in Bolivia

“…This insect pest has a wide distribution, mainly throughout much of the Asian continent, Africa and Australia (Spencer, 1973;Dempewolf, 2004). In recent years, its presence has also been recorded in Europe (Gil-Ortiz et al, 2010) and more recently in the Americas (Arnemann et al, 2016a;Guedes et al, 2017). Among the causes that have resulted in these accelerated changes in the geographic distribution of SSF we can include the intensification of trade that favors the colonization of new habitats and provides new and propitious environments for this pest (Régnière, 2009).…”

Population Status of Biological Control Agent: Sphegigaster spp (SPINO.) (Hymenoptera, Pteromalidae) as a Parasitoid on Soybean Stem Fly Melanagromyza sojae (ZEHNT.) (Diptera, Agromyzidae) in the Nubaria Region of Egypt

“…Soybean stem fly is one of the most important pests of soybean in Brazil and Africa (Arnemann et al, 2016a), parts of Russia (Strakhova et al, 2013), Asia (China and India) (Wang and Gai, 2001;Thapa, 2012). In Northern Australia, SSF was also recorded as the major pest in soybean, increasing percentage of infestation from 13% in 2007 to 30% in 2009 (Guedes et al, 2017;Singh et al 2013). Moreover, an outbreak of larvae of M. sojae in Paraguay was recorded as it infested 100% of soybean plants and tunneling in almost 70% of stems (Guedes et al, 2017).…”

First insights of soybean stem fly (SSF) Melanagromyza sojae control in South America

“…The soybean stem fly (SSF), Melanagromyza sojae (Diptera; Agromyzidae), is endemic to many regions in the old World (Dempewolf, 2004). In soybean fields, M. sojae was reported occurring in parts of Russia (Strakhova et al, 2013), Asia (e.g., China (Wang and Gai, 2001)); India and Nepal (Thapa, 2012), Southeast Asia (e.g., Indonesia (Van Den Berg et al, 1995)) and in the New World in Southern Brazil (Guedes et al, 2015;Arnemann et al, 2016a, b) and Paraguay (Guedes et al, 2017).…”
