A team of researchers from INTA Rafaela, Santa Fe, confirmed the presence of the soybean stem fly (Melanagromyza sojae), first reported by the Argentine National System of Surveillance and Pest Monitoring (Sinavimo) in soybean crops in Argentina.
The soybean stem fly is an insect native to Asia. Currently, it is present in Russia, Australia, Spain, Brazil and Paraguay. The insect can reduce both the size of plants and number of pods, affecting crop yield. In Argentina, this species was first reported in 2019 in chickpea crops in northern Crdoba.
Researchers from INTA Rafaela-Santa Fe warned of the presence of this species in soybean crops in central Santa Fe. “It was detected in various samplings carried out since January in the INTA Rafaela experimental field, during tests on various batches in the area,” said Marcia Trossero (Entomology Specialist at INTA).
