Entomology in the twentieth century

A number of landmark events in applied entomology are Listed together with some insect-related studies that have had a major impact on biology in gene ral. In large part, however, advances in our understanding of insects have depended on technological advances, especially in the second half of the ce ntury. The exponential increase in the ease and extent of communication has been critical. Sometimes, as in the field of insect/plant relations, the i deas of a few individuals have been critical with technological advances ha ving a facilitating role. Elsewhere, as in the study of olfaction, major ch anges in understanding have been directly dependent on new technology. Very brief accounts of the impacts on insect-related science of developments in the fields of radio, radioactivity, immunology, imaging techniques, and ch emical analysis are given. Despite the importance of technology, the lovers of their insects continue to have a key role.
