Abstract
Summary The developmental stage of the host pupae has a considerable effect on the intensity of their siphonogenic reactions. This intensity also depends on other factors: the penetration site of the planidium, the temperature, the fact that the planidium will or will not die during its fixed period, the forward-moving behaviour of the planidium, and the superparasitism. Even when all other things are equal, the intensity of the siphonogenic reaction still varies extensively from one host-parasite pair to another. This results in part from the individual variability of the host pupae but, without a doubt, mainly, from the large individual variability of the planidia. Furthermore, a group variability within hosts and within parasites from different origins may be observed.
