The invention relates to an artificial Reticulitermes cultivation method with outdoor nest groups, which includes the steps of field nest group positioning, winged Reticulitermes collection, preparation of simulated chamber nesting units, installation of nest fixing pipes, artificial synchronous swarming, sex determination and dealation, dealate Reticulitermes pairing and settling, regular check and maintenance, anatomic observation and the like. The nest groups are maintained at 15 DEG C for one to two weeks so that all winged Reticulitermes in each nest is about to swarm, the nests are moved indoors, and net covers are used to collect the swarming Reticulitermes. A green land is divided into a plurality of plots, the nest fixing pipes are driven in, pine blocks are placed into the nest fixing pipes, one pair of the dealate female and the dealate male which pair successfully are placed into one nest fixing pipe of a corresponding number, and an opening of the nest fixing pipe is covered with a glass sheet and covered with a plastic barrel. Nesting conditions and temperature and humidity are observed every 2-3 days, the temperature and the humidity are kept, and part of the nests can be subjected to anatomic observation and statistics after five months. The artificial Reticulitermes cultivation method with outdoor nest groups is simple in operation and high in success rate, nesting success rate can reach 65%, ranks such as youths, soldiers and the like are generated, and the method is worthy of popularization and application.
