Brazil is the most important sugarcane producer in the world. The main pest of this crop is the sugarcane borer, Diatraea saccharalis (Lepidoptera: Pyralidae)which injuries culms and cause enormous yield losses. It is known that the borer attack induces expression of several genes, however, little is known about the phenotype changes of herbivore-induced sugarcane. Therefore, this project aims to investigate the induced defense mechanisms in sugarcane against herbivory (the sugarcane borer, D. saccharalis, and the fall armyworm,Spodoptera frugiperda) and the infection by the red rot, Fusarium moniliforme, commonly associated with the borer culm damage. The proposal addresses questions of how the plant allocates defenses under multiple attack or fungus infection, hence it will determine how these changes affect herbivores and the third trophic level, represented by the parasitoid Cotesia flavipes (Hymenoptera: Braconidae). The methods used here comprise behavioral assays, olfactometry, plant volatile collection, phytohormone measurement, GC-FID, GC-MS and GC-EAD. The project will reveal sugarcane adaptive mechanisms under more complex interactions and closer to what happens in field.
