Overwintering survival of Filipjevimermis leipsandra postparasitic adults ranged from 12 to 15% over 2 years. Nematodes recovered from biweekly samples oviposited within a week when exposed to warm temperatures, More nematodes were recovered from the lower portions of soil cores than from the upper. In laboratory tests of cold tolerance, the LD50 at -5 C was 5.5 hours, whereas exposure to -2 C for as long as 96 hours resulted in no mortality.
