LSU Doctoral Dissertations
The Mexican rice borer, Eoreuma loftini (Dyar) (Lepidoptera: Crambidae) is an invasive stem borer pest of sugarcane, rice, corn, and sorghum, and poses a threat to the production of dedicated bioenergy feedstocks in the U. S. Gulf Coast region. Studies were conducted to assess insect-plant interactions between E. loftini and bioenergy and conventional cultivars of sugarcane and sorghum, including yield response, oviposition preference, and host suitability. In addition, the efficacy of select cultural and biological control tactics to manage E. loftini in these crops was assessed. Bioenergy sugarcane (energycane) and sweet sorghum exhibited reduced E. loftini injury; however, these crops …
