Multiple choice

Neonicotinoid pesticides bind to receptors and have which of the following effects on insects:

  1. Activate synaptic transmission at cholinergic synapses

  2. Activate synaptic transmission at adrenergic synapses

  3. Block synaptic transmission at cholinergic synapses

  4. Block synaptic transmission at adrenergic synapses

C Correct answer
Explanation

Neonicotinoids are agonists that bind to nicotinic acetylcholine receptors. By binding to these receptors, they cause overstimulation and eventually block synaptic transmission at cholinergic synapses in insects.
