“…In regions where M. sojae is endemic, control measures involve mainly the use of resistant cultivars and sowing outside population peaks (Guedes et al, 2017), but biological control with endemic beneficial insects is often mentioned as a potential control strategy against this pest (van den Berg, 1995;Fand et al, 2017). In fact, native natural enemies were reported parasitizing M. sojae in South America (Salgado-Neto et al, 2017) and other regions (Fand et al, 2017), but the role of these parasitoids in regulating pest populations is still unknown. Also, chemical insecticides have been used as the main strategy for controlling M. sojae, but outbreaks recorded in Paraguay suggest that chemical control is not always effective against this pest (Guedes et al, 2017).…”
