[Hemocytic reactions in lepidoptera pupae. Intensity of the reaction as a function of its localization in Pieris brassicae].

Quantitative studies were made on cellular capsules formed in diapause pupae of Pieris brassicae. A simple procedure is to implant pieces of nylon thread in hemocoele. Differences have been noticed in the vigour of the reaction at different regions of the pupae : the haemocytic reaction was less vigorous in the central region of pupae than in the distal ones.
