Sugarcane variety produces natural biodefensive against sugarcane borer
Mar. 20, 2020
Metabolic analyzes have shown that the sugarcane variety SP791011, developed by the Centro de Tecnologia Canavieira and currently in the public domain, produced chlorogenic acid on its own when attacked by the sugarcane borer. In the same environment, plants of the same variety in the control group that were not subjected to an attack by the herbivore did not show elevated acid expressions.
This substance has a harmful effect on pests of different cultures, such as corn, coffee and tomatoes, affecting their development and neutralizing their economic impact on crops. In the study conducted with sugarcane, which also involved experiments with the addition of chlorogenic acid to the borer diet in its caterpillar phase, Diatraea saccharalis showed faster development in the pupa phase, however, it was associated with wing deformation in the moth phase when exposed to all acid concentrations.
Researchers pointed out that chlorogenic acid can be considered a natural biodefensive, and its production can be induced to develop sugarcane varieties more resistant to the sugarcane borer.
