- eggs are produced 24-36 hours after first blood meal
- eggs are laid on host
- eggs are white and oval shaped
- eggs slip off host into enviroment
- eggs hatch within 1-10 days depending on humidity and temperature
explain the larva stage of the flea life cycle
- larvae are slender and white and resemble maggots
- larvae ear organic debris, especially flea dirt
- larvae need high humidity to survive and are sensitive to heat and light
- larvae go through 2 moults or 3 instars in 5-11 days
- larvae produce a sticky cocoon in which they pupate
explain the pupae stage of the life cycle
- cocoon is white and oval shaped
- cocoon is sticky and collects debris to camouflage
- pupae are resistant to chemicals and drying out
- emergence occurs in 3-9 days depending on pressure heat and Co2
- if conditions are not met can be dormant for 2 years
- cocoon holds pre emerged adult which pops out quickly
explain the adult stage of the flea life cycle
- emerged adult immediatly lands on host
- adult uses proboscis to find blood vessel
- flea saliva prevents coagulation of blood
- flea saliva causes FAD
- flea feces causes cat scratch disease in humans
- fleas are usually scratched or groomed off host before reaching its lifespan of 100 days
- fleas are obligate external parasites and do not jump of the host
