Approaching BUDDE intersection and descending to capture the glideslope on the ILS Z RWY08; Tower advised us of traffic below at our 1-2 o'clock position. While looking outside for the traffic we received a TCAS TA ('Traffic; Traffic'). Unable to visually locate the aircraft; I briefly glanced back inside at my display and saw that the intruding aircraft was just off our right side at 800 feet below. I returned to scanning for the traffic and advised ATC that it was not in sight. A few moments later; we received an 'Adjust Vertical Speed' TCAS advisory; with the intruding aircraft now displayed in red at 500 feet almost directly beneath us. The captain shallowed our descent rate; and the other pilot subsequently advised ATC that they had us in sight; although I never visually acquired this aircraft.
We were cleared for an ILS Rwy 8 approach. Approaching BUDDE; ATC warned of traffic below us. I was about a half dot above glideslope and descending to capture it at about 1200 fpm. While looking for the traffic we got a monitor vertical speed and I believe I cut the descent rate to about 200fpm while looking for the traffic. I saw the TCAS traffic display in red 400 feet symbol at the closest point of the encounter. We never saw the traffic.
