Diatraea saccharalis is the principal pest of sugarcane in Brazil and found throughout crop.Information about its population genetics scarce, but genetic analysis particular importance as a basis for successful control program.Pest requires constant evaluation variability so that appropriate strategies can be employed.In this study, structure D. populations crops was analyzed with PCR-RAPD (Polymerase Chain Reaction-Random Amplified Polymorphic DNA) markers.Samples were collected from four fields ParanáState one São PauloState.Twelve primers used.The produced 216 fragments, 99.54% polymorphism rate.The Shannon index averaged 0.3797 (± 0.1729), average value G ST five 0.0909.These results showed are differentiated.An molecular variance 92% occurs within populations.The high rate these shows insects have potential to develop resistance insecticides.The management should conducted cautiously integrated using chemical biological control.
