Document Summary
Queen ant and head of solider ant; ant has mermithids; screws up its morphology. Changes entire body parts; i don"t like that head, i"ll give you a new one! Babies and soft parts make the best things to plough through/ tear open. Always hatch in the alimentary tract of the insect; Loosely host-escape; motile insects find it hard to catch it, must be quick. Some holes just aren"t meant to be used. Melanization is better than encapsulation" insects may have limited supply. Go melanization- don"t use blood and keep it for itself. In some cases the host response includes the formation of a "giant cell" in the midgut epithelium which is then used by the parasite. Something about a giant cell; lives in the cell and protection. Nematodes enter nervous system of the host are protected from the immune response usually kill host eventually. Nervous system has no immune response, will kill eventually.
