Editing Bombyx mori (section)

== Diseases ==
*''[[Beauveria bassiana]]'', a fungus, destroys the entire silkworm body. This fungus usually appears when silkworms are raised under cold conditions with high humidity. This disease is not passed on to the eggs from moths, as the infected silkworms cannot survive to the moth stage. This fungus, however, can spread to other insects.
*[[Nuclear Polyhedrosis Virus|Grasserie]], also known as nuclear polyhedrosis, milky disease, or hanging disease, is caused by infection with the ''Bombyx mori nucleopolyhedrovirus''<!--ICTV MSL 2018b.v2--> (aka ''Bombyx mori nuclear polyhedrosis virus'', genus ''[[Alphabaculovirus]]''). If grasserie is observed in the chawkie stage, then the chawkie larvae must have been infected while hatching or during chawkie rearing. Infected eggs can be disinfected by cleaning their surfaces prior to hatching. Infections can occur as a result of improper hygiene in the chawkie rearing house. This disease develops faster in early instar rearing.
*[[Pébrine]] is a disease caused by a parasitic microsporidian, ''[[Nosema bombycis]]''. Diseased larvae show slow growth, undersized, pale and flaccid bodies, and poor appetite. Tiny black spots appear on larval integument. Additionally, dead larvae remain rubbery and do not undergo putrefaction after death. ''N. bombycis'' kills 100% of silkworms hatched from infected eggs. This disease can be carried over from worms to moths, then to eggs and worms again. This microsporidium comes from the food that the silkworms eat. Female moths pass the disease to the eggs, and 100% of silkworms hatching from the diseased eggs die in their worm stage. To prevent this disease, eggs from infected moths are ruled out by checking the moth's body fluid under a microscope.
*[[Flacherie]] infected silkworms look weak and are colored dark brown before they die. The disease destroys the larva's gut and is caused by viruses or poisonous food.
*Several diseases caused by a variety of funguses are collectively named [[Muscardine]].
