A – one of the first stages of trophont development after invasion, B – bigger uninuclear trophont adpresses the host cytoplasm, C – trophont with two food vacuoles and central vacuole, D – LM of the same stage as in C. E – host plasma membrane and food vacuole membrane (arrowheads) delimiting food vacuole. F – two membranes (arrowheads), bordering the parasitoid cell in the host.
