Pathogenesis, signs and symptoms of Protozoal infection in insects

Have low virulence (chronic infection) that often does not kill an insect.
Infected insect frequently does not exhibit marked external signs and symptoms (e.g. color changes and abnormal movement or behavior).
Infected insects become chlorotic or whitish, are reduced in size, and remain in the immature stages much longer than the uninfected individuals.
Turn to milky white and integument of dead insects remains firm and does not readily disintegrate.
Nosema bombycis: causes discase in silkworm
Malpiagnamoeba locustaeecauses: cause disease in Grasshopper
Glusea mesnili: attack on Pieris rapae
