The development and survival of egg, juveniles (parasitic), preovipositing and ovipositing stages of the parasitic mermithid Filipjevimermis leipsandra were determined at 8 temperatures. Infection of the chrysomelid host, Diabrotica balteata, peaked at 30 degrees C and fell off sharply at warmer or cooler temperatures. No development, oviposition or infection occurred at <20 degrees C. Fecundity was highest at 25 degrees C, and 50% of the eggs were laid in the first 4-7 days of oviposition.
