← Nature & AnimalsWhich factor inhibits metamorphosis from pupae to adult in parasitoid infected insects?
A)Ecdysone biosynthesis suppression✓
B)Increased juvenile hormone secretion
C)Prothoracic gland apoptosis inhibition
D)Enhanced imaginal disc proliferation
💡 Explanation
When parasitoids infect pupae, toxins target and disrupt the insect's endocrine system, specifically inhibiting ecdysone biosynthesis because the parasitoid needs the host resources for own development. Therefore developmental arrest results by hormone deprivation, rather than continued juvenile hormone presence, gland disruption or imaginal disc propagation which drive larval development.
