Method for realizing three-dimensional propagation of Aphidius gifuensis Ashmaed by means of cuttage plant

The invention discloses a method for realizing three-dimensional propagation of Aphidius gifuensis Ashmaed by means of a cuttage plant. The method comprises the following steps of 1) cultivating Gynura japonica as a host plant; 2) breeding aphids; 3) breeding the Aphidius gifuensis Ashmaed; and 4) collecting mummy aphids for manufacturing an Aphidius gifuensis Ashmaed egg aggregate. The method has advantages of short period, small space requirement and easy mummy aphid collection. The method can greatly reduce an Aphidius gifuensis Ashmaed propagation cost and can promote large-scale propagation and commercial production of the Aphidius gifuensis Ashmaed.
