In the fall armyworm, Spodoptera frugiperda (Lepidoptera, Noctuidae), two
sympatric strains have been recognized that have been termed corn strain
(C) and rice strain (R), referring to their most common host plants. Both
strains are reproductively isolated via a distinct prezygotic barrier as
well as via an intriguing postzygotic phenomenon: when R females have
mated with C males, the resulting RC hybrid females exhibit dramatically
reduced fertility independent of their mating partner. Here we demonstrate
that the reduced fertility is caused by the fact that these females
refrain from mating, i.e. females are behaviorally sterile. We identified
a Z-chromosomally linked sterility locus that is most likely incompatible
with yet-to-be-identified autosomal (or cytoplasmic) factors leading to
the observed sexual abstinence. Within-chromosome mapping revealed the
sterility locus to be located in an area of strongly reduced inter-strain
recombination.
