The objective of this study was to test the preferences of E.
platyhypenae towards two fall armyworm host strains fed different
host plants and to determine how plant type affects the
performance of parasitoid wasps. We compared parasitoid
host-preference, brood size, parasitoid larval survival and brood
sex ratio in corn and rice strain larvae fed either corn Zea mays L.
(‘Trucker’s Favorite’) or stargrass (Cynodon nlemfuensis var.
nlemfuensis Vanderyst, (‘Florona’). The results of this study lead
to a discussion of parasitod-host behavior for biological control
