We present the results of a search for leptoquark (LQ) pairs in (85.2±3.7)  pb-1 of pp̅ collider data collected by the D0 experiment at the Fermilab Tevatron. We observe no evidence for leptoquark production and set a limit on σ(pp̅ →LQLQ̅ →νν+jets) as a function of the mass of the leptoquark (mLQ). Assuming the decay LQ→νq, we exclude scalar leptoquarks for mLQ<98 GeV/c2, and vector leptoquarks for mLQ<200 GeV/c2 and coupling which produces the minimum cross section, at a 95% confidence level.
