Within some 125 years in the development of the natural sciences, insect management passed through a number of distinguishable phases of increasing complexity and sophistication., Lobesia botrana management can serve as an example. Biochemical physiologists, classical entomologists, toxicologists, analytical and chemical ecologists, as well as engineers both at the molecular and field level, had about equal merits in achieving today's high state of knowledge and perfection. Although the golden age of all-round pest management is by no means in our hands, we collectively reached at least a status where we could claim considerable progress towards environmentally sound pest management unthinkable only 50 years ago [1-4]. In detail, we might briefly distinguish 7 major phases of accomplishments, leading to today's technical level:
