Fall Armyworm Symposium: Sugarcane Resistance to Stalkborers (Lepidoptera: Pyralidae) in South Texas
Abstract
Evaluation of 5 commercial sugarcane clones (cultivars) and 54 noncommercial clones which are part of the Texas A&M University sugarcane breeding program indicated that there were significant differences among clones to injury by the Mexican rice borer, Eoreuma loftini (Dyar). The commercial clone CP 70-321 was among the most resistant clones in all tests. However, the clones TCP 83-3196 and TCP 83-3180 were significantly less injured than CP 70-321, and 7 other clones exhibited levels of resistance similar to CP 70-321. Eoreuma loftini injury levels averaged 29.4% bored internodes; the sugarcane borer, Diatraea saccharalis (F.) population levels were low in both years causing less than 1.0% bored internode injury to sugarcane.Downloads
