A production surface for rearing and/or breeding of insects and/or larval forms of insects, comprising: a) at least one breeding surface for breeding insects for laying the feed thereon, wherein preferably the breeding surface comprises at least one storey, which constitutes an autonomous conveyor belt, preferably with profiled lateral sidewalls arranged bilaterally along the direction of movement of the conveyor belt, wherein preferably the edges of the lateral sidewalls are bent inwards, wherein the rearing and/or breeding of insects and/or larval forms of insects concern insects of the orders Coleoptera and/or Diptera, characterized in that the production surface further comprises: b) an underfloor feed heating and/or cooling system with a closed flow of heating-cooling medium for heating and/or cooling the feed on the breeding surface, wherein the underfloor feed heating and/or cooling system with a closed flow comprises at least one heating-cooling medium supply circuit and at least one heating-cooling medium return circuit connected to each other, wherein the heating-cooling medium supply circuit and the heating-cooling medium return circuit are fluidly connected to a heat exchanger for heating/cooling the heating-cooling medium, wherein the heating-cooling medium supply circuit and the heating-cooling medium return circuit comprise distributors for the heating-cooling medium, wherein heating-cooling pipes of thermally conductive material are connected are connected to the heating-cooling distributors via shut-off valves, wherein the heating-cooling pipes of thermally conductive material of the underfloor system for heating/cooling the feed on the breeding surface are permanently integrated directly into said at least one breeding surface for laying the feed for insect breeding thereon, wherein the heating-cooling medium supply circuit and the heating-cooling medium return circuit are connected via a three-way valve. a) at least one
