The invention discloses a method for improving the eclosion rate of larvae or nymphs of macadamia nut juice-eating leaf insects, and belongs to the technical field of insect feeding. The invention discloses a method for improving eclosion rate of larvae or nymphs of macadamia nut juicy leaf insects, which comprises the following steps: covering the larvae or nymphs and newly-drawn tender shoots with a white nylon mesh bag with 200-300 meshes, and tightening the bag opening with a rope, so that the larvae or nymphs cannot escape. If the tender leaves are completely eaten or the tender shoot juice is completely sucked, larvae or nymphs need to be transferred to another newly-drawn tender shoot until the larvae pupate and eclosion, and adults are collected for research. By means of the method, the eclosion rate of larvae or nymphs can be increased to 80% or above.
