A two-year cooperative study of the LSU Agricultural Center and Texas A&M Stations at Beaumont and Weslaco was conducted to determine the relative susceptibility to the Mexican Rice Borer, Eoreuma loftini (Dyar), of the four commercially grown Louisiana sugarcane varieties at two sites in Texas. Based on percent bored internodes under both moderate and heavy infestation pressures and other biological parameters, varieties HoCP 91-555 and LCP 85-384 were significantly (P<0.05) more susceptible than HoCP 85-845 and NCo 310, the most susceptible commercially grown sugarcane variety in Texas. CP 70-321 had an intermediate level of susceptibility. The candidate Louisiana variety HoCP 96-540 is also being studied.
