Answer:

D. Fumigant

• Fumigant: The pesticide or toxicant enters into the tracheal system (respiratory poison) through spiracles in vapour form.

• Systemic poison - Pesticides applied on the plant parts or on soil are absorbed by the foliage (or) roots and translocated through vascular system. Such pesticides cause death of insect feeding on plant.
