This fourth volume of reviews of selected entomological subjects maintains the high standards and objectives of earlier volumes. Scientists from seven countries contribute 19 papers and each is a pertinent current review of worldwide studies on the subject. The reviewer would draw the particular attention of readers of this journal to three chapters: “Culture of Insect Tissues” by Day and Grace, “Fleas and Diseases” by Jellison, and “Insects and the Epidemiology of Malaria” by Russell.
The paper on insect tissue culture is most timely as it summarizes historical and current studies which have not been brought together previously. Current interest in the subject is dictated by the need for methods of maintaining pathogenic agents in vector tissues without intermediate passage through vertebrate or plant hosts. Factors which have limited the success of attempts to culture insect tissues are summarized as are the avenues which may lead to future success.
