Final answer:
Pediculosis is caused by head lice, body lice, and pubic lice that infest different parts of the body and lay their eggs in different locations.
Step-by-step explanation:
Pediculosis, which comes in three forms, is caused by three different types of lice associated with humans: the head louse (Pediculus humanus capitis), the body louse (Pediculus humanus corporis), and the pubic louse (Pthirus pubis).
Head lice and pubic lice infest hair, laying their eggs at the base of hair fibers, while body lice infest clothing and lay their eggs on fibers in the fabric.
The coevolution of humans and lice is a developing area of research, and studying lice variations provides insights into human evolution and migration.
