Untersuchungen über die hämocytäre Abwehrreaktion der Puppe von Galleria mellonella L. (Lepidoptera) und über ihre Hemmung durch den Puppenparasiten Pimpla turionellae L. (Hym., Ichneumonidae)1, 2

Studies on the hemocytic defence reaction of the pupa of Galleria mellonella L. (Lepidoptera) and its inhibition by the pupal parasite Pimpla turionellae L. (Hym., Ichneumonidae). The pupa of Galleria mellonella is capable of encapsulating various kinds of dead foreign bodies. The violence of the defence reaction depends on numerous endogenic and exogenic factors. The encapsulation process causes an increase in the respiration of the host pupa. Eggs of Pimpla are enveloped only at a very low rate, which seems to be due to a surface effect of the eggshell, attained by a superficial layer of secretions from the oviducts and accessory glands of the female genital tract.
