Apple growers in Israel appear to have unwittingly enlisted the help of super-powered nighttime avengers in their battle against pests. Insectivorous bats, which are an effective alternative to chemical insecticides, defend the apple orchards not out of a sense of justice, but mostly because they offer a more bountiful bug buffet than do natural forests, a recently published study shows.
