Cediopsylla simplex

(Baker, 1895)

Cediopsylla simplex is a in the Pulicidae. Its reproductive is tightly coupled to hormonal cycles, with female maturation occurring specifically on pregnant rabbits and nestlings rather than on estrous does. The species has been described as " bound," indicating that its breeding cycle is controlled by and synchronized with the breeding cycle of its host. This physiological dependency represents a specialized among fleas.

Diet

Blood-feeding on rabbits; specific dietary details beyond not documented.

Host Associations

Sylvilagus floridanus - Eastern cottontail rabbit; identity inferred from source mentioning "hare " parasitizing this
Oryctolagus cuniculus - European rabbit; inferred from description of reproductive on pregnant does and nestlings

Life Cycle

Female maturation occurs on pregnant rabbits and nestlings, but not on estrous does. If matured fleas are transferred to estrous does, ovarian resorption occurs. The breeding cycle is controlled by and synchronized with the breeding cycle.

Similar Taxa

Spilopsyllus cuniculiBoth described as " bound" with reproductive tied to hormonal cues; share similar reproductive strategies involving responses and spring-time breeding acceleration

More Details

Hormone-bound reproduction

Cediopsylla simplex exhibits a rare physiological among fleas where its reproductive cycle is directly controlled by sex . Female fleas only mature when feeding on pregnant hosts or nestlings, and mature fleas transferred to non-pregnant (estrous) hosts undergo ovarian resorption. This represents an extreme form of host- physiological integration.
