Earthworms as pests and benefactors

Abstract

Certain of the habits of earthworms make them potential pests of crops. The habit of certain species of seizing fallen leaves and pulling them down through the mouth of their burrows, means that if they seize the leaves of growing plants in this way, they damage the plant, sometimes sufficiently to kill it. Zicsi (1954) reported such damage to various crops, and Edwards (unpublished) noted that earthworms destroyed a large part of a lettuce crop in this manner.
