A.

Sucking pest

B.

Leaf feeder

C.

Root feeder

D.

Pod feeder

Correct option is A

The correct answer is: (A) Sucking pest
Explanation:
Mustard aphid (Lipaphis erysimi) is a sucking pest that feeds by piercing the plant tissues and sucking sap from the leaves, stems, buds, and pods of mustard and other cruciferous crops.
This leads to curling of leaves, yellowing, stunted growth, and even reduction in yield and oil content in mustard crops.
Information Key Points:
  • It causes leaf curling, yellowing, and weakening of plants.

  • Heavy infestations can severely reduce pod formation and seed quality.

Additional Information:
  • Leaf feeders chew the leaf surface (e.g., caterpillars) and are different from sap-sucking pests.

  • Root feeders (like some grubs or nematodes) live in the soil and feed on roots.

  • Pod feeders directly damage the pods and developing seeds, whereas aphids feed externally on green parts.
