Can I use dual time for the 10 night takeoffs and landings required in 61.129?
No being under the hood does not count as &quot;night flying&quot; see this question for the FAA's definition of night flight.
You dont need to be alone in the aircraft for these TO/LD's while the FAA definition of &quot;solo flight&quot; which this question covers could apply it does state that an instructor can be present

(4) Ten hours of solo flight time in a single engine airplane or 10 hours of flight time performing the duties of pilot in command in a single engine airplane with an authorized instructor on board (either of which may be credited towards the flight time requirement under paragraph (a)(2) of this section), on the areas of operation listed under § 61.127(b)(1) that include -


(ii) 5 hours in night VFR conditions with 10 takeoffs and 10 landings (with each landing involving a flight in the traffic pattern) at an airport with an operating control tower.
