摘要：
Fall armyworm, Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae), has resistance to many groups of synthetic insecticides. Our objective was to evaluate the efficacy of Steinernema carpocapsae (Weiser) (Nematoda: Steinernematidae) in combination with low-toxicity insecticides at low and high dosages to control fifth-instar larvae in bioassays. The use of S. carpocapsae + chlorantraniliprole or spinetoram caused larvae mortality of over 90% at 72 h at the high dose and should be included as a least toxic strategy to control fall armyworm. © 2018 Florida Entomological Society.
