How many insect species are necessary for the biological control of insects?
Environmental Entomology 18 (4), 541-547
Abstract: The authors analyzed 50 published successful classical biological control programs in which an average of 3 species of beneficials were introduced against insect pests. 32% of the successes were credited to a complex of introduced agents (in these cases an average of 2.7 species were introduced). However, twice as many successes were credited to only one of several introduced species (in these cases an average of 3.6 species were introduced).
