← Nature & AnimalsWhich endocrine disruption negatively affects holometabolous larval development during metamorphosis?
A)Premature activation of the Corpus allatum✓
B)Reduced competence of the imaginal discs
C)Inhibition of prothoracic gland activity
D)Upregulation of juvenile hormone receptors
💡 Explanation
When endocrine disruptors activate the Corpus allatum prematurely, excessive juvenile hormone (JH) is produced because JH suppresses metamorphosis until larva has reach ideal size and nutrient capacity, blocking pupation. Therefore premature activation affects pupae development, rather than disc apoptosis, prothoracic inhibition, or receptor expression which lead to different developmental failures.
