Cordyceps militaris uses an insect-like protein to manipulate its silkworm host into feeling like it’s starving, plumping it up to benefit fungal reproduction.



Summary

The Cordyceps militaris fungus employs a cunning strategy to exploit silkworms. It produces a protein mimicking insect hormones, tricking the silkworm into experiencing extreme hunger. This induced starvation prompts the silkworm to consume more, leading to significant weight gain. This increased biomass then serves as a nutrient reservoir for the fungus. By manipulating the silkworm’s appetite, C. militaris ensures optimal conditions for its own growth and reproduction, effectively turning its host into a living pantry.
