Abstract/Contents: | "Black cutworm (Agrotis ipsilon Hufnagel) is a destructive pest of golf course turf. Previous work suggests that Poa pratensis 'Midnight' is resistant to black cutworm, but it is not known if resistance also exists among other Poa species and cultivars. This study compared preference and performance of black cutworm on Poa species and cultivars to a susceptible host plant, creeping bentgrass (Agrostis stolonifera L. 'Penncross') in laboratory choice feeding assays and rearing experiments. Seven-and 14-day-old larvae were used in performance feeding tests. Larvae reared on all Poa spp. exhibited significantly lower development and survival rates than larvae fed creeping bentgrass. Young (7 days old) larve did not survive to pupation. Although older (14 days old) larvae pupated and eclosed[enclosed] on Poa, larval weight gain was significantly lower than those reared on creeping bentgrass. In choice feeding bioassays, regardless of larval stage, black cutworm preferred creeping bentgrass over all Poa species and cultivars. The results of this research suggest that although Poa species are generally resistant to black cutworm, the resistance varies among cultivars and insect growth stage." |
