Chemical warfare between plants and their herbivores and pathogens
was first brought to our attention by the publication 25 years ago
of the paper by Fraenkel in Science. There, he pointed out that
most plants have similar nutritional characteristics so that the
selection of plants by insect herbivores must depend on the
relative toxicity of secondary compounds. This led, rather
gradually, to a host of papers on plant-herbivore interactions.
More or less at the same time, insect physiologists and ecologists
were starting to realise the importance of chemical communi cation
systems in determining sexual and other characteristics of insect
behaviour. Nine years ago the Phytochemical Society of North
America published their Symposium on 'Biochemical Interaction
Between Plants and Insects' in which the plant apparency theory was
expounded by both Paul Feeny and Rex Cates and David Rhoades. This
stated that plants which are apparent usually contain secondary
components which reduce digestibility (tannins and lignins) while
ephemeral plants have more toxic, and perhaps less costly,
compounds such as alkaloids. These papers stimulated much research
on biochemical ecology. The recognition of the importance of the
biochemical factors in such interactions is not just of scientific
interest. It is vitally important in programs for the production of
new varieties of cultivated plants, especially in tropical
countries where about one-third or more of the crops are lost to
predation or disease."
