It was
observed that the parasite was comparatively larger
when the intensity was less; also the parasites
recovered from the female host species were larger
than those recovered from the male host species;
accordingly the various internal organs of these
parasites were variable; larger in large specimens
and smaller in small specimens. Since the parasites
compete for food and shelter the parasites which get
plenty of food, when the number is less they become
large compared to the situation when the number is
high. One possible reason for large size of this
parasite in male hosts compared to those recovered
from the females could be that males have
comparatively strong immune system which could
have checked the growth of these parasites or it may
be due to some female hormonal effects or some
other physiological factors.
