Abstract
Thirty clonal selections of Bermudagrass, Cynodon
spp., were exposed in field cages to adults of the tropical
sod webworm, Herpetogramma phaeopteralis Guenée, in
two experiments. This webworm is a severe pest of turfgrasses
in the lower Southeastern United States, especially Florida,
and many islands of the Caribbean Archipelago. Fewer
larvae completed development to adults on PI-298750, PI-290884,
PI-290899, PI-289931, 'Tuffy', 'Ormond', 'Tufcote', 'U-3'
and 'Tiffine' relative to other commercial cultivars and genotypes.
Adult preference or larval antibiosis/tolerance was exhibited.
The four PIs exhibited cross resistance to the fall armyworm.
