Parasitization of fall armyworm by the eulophid parasitoid Euplectrus platyhypenae. Florida Entomological Society Annual Meeting. Interpretive Summary: Technical Abstract: Fall armyworm, Spodoptera frugiperda (J. E. Smith), is attacked by parasitoids from several different families of Hymenoptera and Diptera. One species, Euplectrus platyhypenae Howard (Hymenoptera: Eulophidae), has been consistently recovered from larvae in whorl-stage corn and from larvae feeding in pasture grasses. This species is a gregarious larval ectoparasitoid attacking all stages of larvae except neonates. Parasitization rates for this species have been as high as 53% in spring-planted corn in Alachua Co., although the average rate for the last two years has been 22.3%. This parasitoid is easy to culture in the laboratory and future studies will determine if timely releases will help reduce fall armyworm populations. |
