,HELMINTH/WORM TERMINOLOGY
• Adults: sexually reproductive life cycle stage
• Larvae: developmental or asexually reproductive life
cycle stage
• Eggs: stage protective of zygote &/or embryo
• Cysts: usually a larval stage encapsulated in tissues of an intermediate host
• Hypobiosis: worms in temporary developmental arrest.
• Monoecious/hermaphroditic: both sexes 1 body
• Dioecious: sexes separate; males & females
• Parthenogenesis: Ability to produce offspring without fertilization of eggs
, Worm-terms, continued
• Oviparous: production of eggs, discharged from uterus of fem
• Ovoviviparous: production of eggs which hatch prior to discha
from uterus of female
• Viviparous: production of embryos/L1 larvae, no rigid
encapsulation of embryo.
