At concentrations between 0.020 and 0.600 μL/cm2, therewere statistical differences between the antifeedantproperties of tested EOs against A. fusca (0.020 μL/cm2, F=16.15; P=0.000 2; 0.200 μL/cm2, F=22.26; P<0.000 1;0.400 μL/cm2, F=21.53; P<0.000 1; 0.600 μL/cm2, F=34.67; P<0.000 1; Table 1). However, for E. elaeasa, thesedifferences occurred only at 0.600 μL/cm2 (F=20.57; P<0.0001; Table 1). Post-test analysis revealed that forsome concentrations at which there were statisticaldifferences between EOs, for A. fusca, C. martinii showedsignificant differences against C. nardus and C. flexuosus;whereas for E. elaeasa, the only detected difference wasobserved between C. martinii and C. flexuosus at 0.600 μL/cm2. On the other hand, when comparing A. fusca vs. E.elaeasa, only the EO of C. martinii presented greater activityon the first, and this happened at 0.020, 0.400 and 0.600 μL/cm2 (T=3.54; P=0.005; T=2.97; P=0.01; T=4.29; P=0.002; Table1). The activities of tested EOs were compared to that elicitedby the commercial repellent IR3535. For A. fusca, only theoils from C. martinii and C. nardus were significantly greaterthan the positive control at concentrations greater than0.002 μL/cm2, whereas for E. elaeasa, such difference wasregistered for C. martinii at the greatest tested concentration.Finally, based on the FI-values (Table 2), the antifeedantproperties of the EOs against A. fusca decreased in the order C. martinii≈C. nardus>C. flexuosus, whereas for E. elaeasait was C. martinii≈C. nardus>C. flexuosus. In both cases, theEO isolated from C. flexuosus was the least potent.
