| Abstract/Contents: | "The fall armyworm, [Spodoptera frugiperda (J. E. Smith)] (Lepidoptera: Noctuidae), feeds heavily on many species of cool- and warm-season turfgrass in the Americas and the Caribbean Basin. Severe outbreaks do not occur each year but rather every 2-3 years, and sometimes it may be up to 5 years between outbreak cycles. 2010 appears to be one of the severe outbreak years with damaging populations occurring across much of the U.S. Forty-six cultivars and genotypes of Kentucky bluegrass, (Poa pratensis L.), were characterized for their resistance or susceptibility to fall armyworm larvae in no-choice laboratory experiments. Results include: The majority of the Kentucky bluegrasses cultivars (32) provided 100% mortality before adult emergence. An additional seven cultivars provided greater than 90% mortality, and two more produced greater than 80% mortality. The most susceptible cultivars was 'Glade' with 8% mortality, followed by PTDF22B2 (25%), 'Kenblue' (29%), 'Connie' (58%), and H86-386 (67%). 'Reveille', a Texas bluegrass O Kentucky bluegrass (Poa arachnifera O P. pratensis) hybrid, was 100% resistant, characteristic of 'Huntsville' its Kentucky bluegrass parent, as opposed to 'Tejas', the Texas bluegrass parent. Analysis of the group of Kentucky bluegrass genotypes shows a gradation of resistance, with 'Wabash' killing 100% of larvae within 3 days feeding, an additional nine cultivars killing 100% within 9 days, and 22 additional cultivars killing 100% before the adult emerged. The data indicates 'Wabash', 'Adelphi', 'Eagelton', and 'Monopoly' (each producing greater than 92% mortality within 3 days feeding) present the greatest potential for transferring fall armyworm resistance in hybridization of future cultivars." |
