Explore key strategies and challenges in managing sucking pests that affect cumin crops, including identification, prevention, and integrated approaches. Test facts about effective pest management using real-world agriculture scenarios.
Which of the following insects is a primary sucking pest known to attack cumin crops and cause significant yield loss?
Explanation: Aphids are recognized as major sucking pests of cumin, feeding on plant sap and weakening crops. Termites and cutworms are primarily soil pests targeting roots and stems, not sap. Red spider mites can attack cumin but are less common than aphids as major yield reducers.
If you observe curled, yellowing leaves and honeydew deposits on cumin plants, which pest infestation should you suspect?
Explanation: Aphid infestations typically cause curled/yellow leaves and sticky secretions (honeydew). Pod borers and armyworms mainly chew on pods and leaves, while root grubs affect underground parts without causing honeydew.
What is one effective cultural practice to help reduce sucking pest populations in cumin fields?
Explanation: Crop rotation with non-host plants disrupts the life cycle of sucking pests, limiting their buildup. Deep irrigation does not target pest populations, late sowing increases pest risk, and excess nitrogen can worsen pest attraction.
Which natural enemy is commonly recommended for biological control of aphids in cumin?
Explanation: Ladybird beetles feed on aphids and are effective biological control agents. Rice weevils, whiteflies, and fruit flies are not predators and are not used for aphid control.
Why is frequent use of broad-spectrum insecticides discouraged in the management of cumin sucking pests?
Explanation: Broad-spectrum insecticides can disrupt ecosystems by killing beneficials like predators and pollinators. They do not increase seed germination, improve flavor, or enhance soil nutrients, making those choices incorrect.
