The function of insect blood cells has long puzzled scientists. This much-needed volume, first published in 1979, attempts to explain the forms and functions of insect hemocytes, creating a solid basis from which work in the field may proceed. Insect Hemocytes had its origins in a symposium held at the XV International Congress of Entomology (1976). It is a coherent presentation whose contributors were some of the most eminent specialists in the field.
