The subject area embraced by the term "biological control" in its
classical sense is very broad indeed. The term itself was
apparently first used in 1919 by the late Harry S. Smith, and was
then used specifically in reference to the suppression of insect
populations by the actions of their indigenous or introduced
natural enemies. The California school of biological control
specialists who followed in Smith's footsteps have traditionally
differentiated "natural" biological control (by indigenous natural
enemies) and "applied" biological control (by man-introduced
natural enemies). Subsequently, the philosophy broadened beyond the
original narrow concern with population suppression of insects (and
especially pest insects), to embrace directed activities against
mites or other arthropod pests, various invertebrate and vertebrate
pests, weeds, and organisms producing disease in humans or their
domestic animals and plants. The techniques used in these
activities also multiplied beyond the original concern with natural
enemies. The subjects area discussed in this book is, at the same
time, broader and more restricted than that covered in other books
on "biological control. " On the one hand, the treatment here is
restrictive in that, with rare exception, we have limited ourselves
to dealing only with ideas and examples involving the suppression
of insect pests through human activity or intervention in the
environment.
