Resumo: | ABSTRACT Plant indirect induced defenses against herbivores are characterized by the production of plant volatiles that to attract natural enemies. The objective of this study was to evaluate whether the attack of the two-spotted spider mite Tetranychus urticae or the multiple herbivory of T. urticae together with the fall armyworm Spodoptera frugiperda are able to elicit indirect induced defense in conventional and Bt maize plants. The experiment was carried out in the laboratory using Y-tube olfactometer, evaluating the predatory mite Neoseiulus californicus olfactory preference for plant volatiles. The treatments involved: Clean Conventional Plant; Conventional Plant Infested with T. urticae; Clean Bt Plant; Bt Plant Infested with T. urticae; Conventional Plant Infested with T. urticae + fall armyworm; Bt Plant Infested with T. urticae + fall armyworm. For the chemical analyzes the Trace GC Ultra gas chromatograph was used, paired with the Polaris Q mass spectrometer, GC - MS system. Neoseiulus californicus was also unable to distinguish between volatiles from both conventional and Bt infested maize plants. Moreover, there was no discrimination of the predator mite between plants under single and multiple infestations, both in conventional and Bt maize. When comparing conventional and Bt plants, both with multiple infestation, the predator mite N. californicus had no preference among these sources of odors. However, there was observed chemical changes of the volatiles among the groups of plants studied. Thus, it is suggested that the groups of plants under study have chemical modifications, but they are not able to attract N. californicus. In addition, Bt plants response was similar to conventional plants on attracting N. californicus. |
