摘要: Several studies have shown that herbivore-induced plant volatiles act directly on herbivores and indirectly their natural enemies. However, little is known about the effect of herbivore damage resistant susceptible cultivars its Thus, aim this study was to evaluate attraction herbivorous pentatomid bug Euschistus heros egg parasitoid Telenomus podisi two one soybean with different types (herbivory, herbivory+oviposition, oviposition). In a Y-tube olfactometer, parasitoids were attracted herbivory herbivory+oviposition damaged plants when compared undamaged for cultivars, but did not show preference cultivar Silvânia in any treatments. The emitted by oviposition-damaged three attract parasitoid. four-arm-olfactometer bioassays, E. females odors or studied. Principal Response Curves (PRC) analysis showed consistent variability over time chemical profile between treatments Dowling. compounds most contributed divergence (E,E)-α-farnesene, methyl salicylate, (Z)-3-hexenyl acetate, (E)-2-octen-1-ol.
