Parasitism by natural enemies of all larval instars of the fall armyworm (FAW), Spodopterafrugiperda, was quantified in 5 Honduran maize fields during the 1984 growing season. Overall, 42.0 % of the host larvae were killed by the natural enemy complex. The braconid parasitoid Chelonus insularis was the most common natural enemy accounting for 36.8 % of the complex and causing 15.5 % mortality of FAW larvae. Other important natural enemies included the nematode Hexamermis sp., the tachinid Lespesia sp. and the imperfect entomopathogenic fungus Nomuraea rileyi. Distinct ranges of larval instars were attacked by several natural enemy species. Chelonus insularis was an important FAW natural enemy at all larval densities observed.
