The pupae work their way entirely out of their cocoons and drop to the ground before bursting their pupal cases, which may be found in abundance on the ground from which a brood has just issued.. Fig. 170.—Grapholitha interstinctana: a, larva; h, pupa; c, adult; all enlarged; d, adult—natural size. (After Osborn.) The remedies for the species are summed up as follows: 1. Rotation of crops, not keeping clover on the same ground over three years, and only two if the field becomes badly infested. 2. That the seed for a new crop be planted on land as remote as possible from old clover fields. 3. That infested fields from which seed is desired the following year be pastured in the fall to take up all late growths and leave the field free from vegetation, and that.
