- Abstract
The Mexican rice borer (MRB), Eoreuma loftini, is an invasive stalk borer which is the dominant pest of sugarcane in Texas and is expected to cause major economic losses to the Louisiana sugarcane industry. A replicated experiment conducted at the Texas A&M AgriLIFE research center in Beaumont which evaluated 19 cultivars for resistance to MRB showed that L 08-075 exhibited a trend to be superior to the resistant standard HoCP 85-845, and that HoCP 04-838 remained one of the most MRB susceptible. Energy cane cultivars showed intermediate levels of resistance. A study conducted to assess predation from the imported fire ant, Solenopsis invicta, showed high levels of apparent MRB mortality (approaching 80%) in plots with natural ant populations. Additionally, increased MRB injury (percent bored internodes) was detected in plots where ants were suppressed with insecticidal baits. MRB pheromone traps are widely used to collect and monitor MRB adult activity; however, the attractive distance of these traps is unknown. A study examined the attractive distance of pheromone traps by assessing the effect of intertrap distance on MRB capture. Results from this study indicate pheromone traps can attract male MRB moths from distances >100 meters.
