AAphids

BSoft-bodied insects

CStorage pests

DInsects resistant to nerve poisons

Answer:

C. Storage pests

Read Explanation:

  • Physical poison - The pesticide or toxicant will not react chemically but kill the insect either by asphyxiation or desiccation.

  • Mineral oil closes the spiracles and causes asphyxiation. So mineral oil is used for soft bodied insects like aphids.

  • Activated clay exerts a physical effect on wax monolayer and create spaces so that depletion of moisture in insect cell occurs. Activated clay is used in storage pest management.

  • Eg: Mineral oil, Inert dusts - Ash, silicagel, activated clay.
