Bud borer (Crocidosema aporema) is an insect pest of soybeans and other fabaceous plants. It is a native of Brazil, Uruguay, Chile and Argentina.
Lower pods are significantly reduced as a result of its attack on terminal buds. Attacked plants may be recognized by the rolled young leaflets, which contain the larvae. The larvae also tunnel along the main and secondary stems and bore into pods.
