Exam III Flashcards
Hyperparasitoids
parasitoids of parasitoids!
Idiobionts
paralyze prey
kionobionts
ALLOW host to continue to mature and grow
Benefits of ectoparasites
Easy dispersal, Safe from Immune system
Downsides to ectoparasites
Vulnerable to natural enemies, exposed to environment, Harder time feeding
Upsides to Endoparasites
More often protected form natural predators, protected from external environment, easier feeding
downsides to Endoparasites
Harder dispersal, More susceptible to host’s immune system
