The soybean looper,Pseudoplusia includens(Walker), is a common pest of soybeans in South Carolina. Loopers contribute to a group of general defoliators which may reach population levels sufficient to cause economic damage. Working withP. includensin Alabama, Harper and Carner (1973) reported that larval populations often are infected with the fungus,Entomophthorasp., which under certain conditions may reduce or eliminate looper populations. Current opinion (MacLeod, personal communication) regards this pathogen as the same species (Entomophthora(Tarichium)gammae) described by Weiser (1965) infectingPlusia gamma(L.).
