“…Furthermore, they attract a great diversity of insects and natural enemies (Supriyadi, Wijayanti, Arniputri, Puspitarini, & Dwiyatno, 2019;Tavares et al, 2010). They are also able to control phytonematodes, benefiting antagonists and producing secondary compounds that are toxic or inhibitory to them, such as the monocrotaline pyrrolizidine alkaloids, which reduce the hatching of juveniles and motility (Galbieri, Fuzattoii, Ciaii, Welteri, & Fanan, 2011;Osei, Gowen, Pembroke, Brandenburg, & Jordan, 2010;Ratnadass, Fernandes, Avelino, & Habib, 2012;Santana et al, 2012). However, despite the literature demonstrating its nematicidal effect, the results presented here show that C. spectabilis maintained the highest and most stable number of viable EPNs on the 3rd day after inoculation, in relation to the other plants evaluated (Figure 2), with no effect on their infectivity (Figure 1).…”
