Abstract/Contents:"Fall armyworm, Spodoptera frugiperda (J. E. Smith), larval survival, weight at 10 days, developmental rate, and pupal weight were significantly greater on fertilized than on unfertilized 'Coastal' bermudagrass, Cynodon dactylon (L.) Pers. A combined analysis over three tests also showed that fecundity was significantly greater for moths that originated from larvae that fed on fertilized grass than for moths that originated from larvae that fed on unfertilized grass. Fall armyworm responses to bermudagrass regrowth were more varied, but in two of the three tests larval survival, weight at 10 days, and developmental rate were significantly greater on young regrowth than on older regrowth. Pupal weight and fecundity showed no consistent relationship with stage of bermudagrass regrowth. Increased 'Coastal' bermudagrass fertilization and younger regrowth primarily influenced larval development, with little influence on pupal development. Calculations showed that fall armyworm population could increase 45- to 225-fold in highly fertilized bermudagrass pastures compared with unfertilized bermudagrass."
