Seasonal Populations of Armyworms and Loopers at Hastings, Florida
Abstract
Seasonal populations of the fall armyworm, Spodoptera frugiperda (J. E. Smith), beet armyworm, S. exigua (Hubner), soybean looper, Pseudoplusia includens (Walker), and cabbage looper, Trichoplusia ni (Hubner), were surveyed in the Hastings, Florida area with pheromone-baited cylindrical electric grid traps. All 4 species survive the relatively mild winter temperatures (@?60@*F) occurring there most years; therefore, the Hastings area may act as a reservoir for overwintering populations of these pest species. Populations that build up in the spring may contribute to the numbers that migrate into other areas of the South and Northeast each spring and summer.Downloads
