“…The results obtained in the experiment with D. melacanthus indicated that the activity of Spn LC 50 was similar to that of either the associated or pure Spn LC 25 , and more efficient than the control treatment (Table 3). It is known that Spn may negatively affect the levels of natural enemies (Firake et al, 2017;Hill & Foster, 2000;Liu et al, 2007) and other beneficial insects (Mayes et al, 2003), where we can find some different results (Fernández et al, 2017;Ishaaya et al, 2005;Rimoldi et al, 2012). However, several authors have reported its efficiency in the control of several pests in urban areas (Khan, 2018;Santos et al, 2019;Valcárcel et al, 2015), stored grains (Athanassiou et al, 2008;Vayias et al, 2009), horti-fruticulture (F. Huang & Subramanyam, 2007;Stark et al, 2004), and even of major agricultural pests (Aydin & Gürkan, 2006;Pineda et al, 2007;Wang et al, 2009).…”
