The utility model relates to a worm rearing box for cultivating soybean pod borers, which can solve the problem that no special worm rearing box for cultivating the soybean pod borers exists in the prior art. Grooves are correspondingly arranged on the front wall and the back wall in a box body along the height direction of the box body, partition boards are inserted in the grooves on the front wall and the back wall in the box body, a big through hole and a small through hole are arranged on a box cover, a gauze screen is mounted at the big through hole on the box cover, the lower end of a circular tube is fixedly arranged at the small through hole of the box cover, the partition boards divide the box body into a worm rearing chamber and an eclosion chamber, the eclosion chamber is positioned below the small through hole on one side of the partition boards in the box body, the worm rearing chamber is positioned on the other side of the partition boards in the box body, and the height of the partition boards is lower than that of the box body. The worm rearing box is applicable to cultivating a large number of larvae of the soybean pod borers and can simultaneously meet the purposes of leading the full-grown larvae of the soybean pod borers to go into the soil to make cocoons and pupation, and leading adult worms after eclosion to fly away and seek egg-laying host targets, thereby realizing high survival rate of the adult worms and high egg-laying rate.
