Understand the Problem
The question paper consists of various topics related to pest management and agricultural science, focusing on concepts such as pest plant resistance, insect-pest management, and integrated pest management (IPM). It requires comprehensive understanding and explanation of specific concepts.
Answer
Host plant resistance reduces pesticide use and promotes sustainability. Allomones and kairomones are chemicals in species interactions. Ecdysone guides insect development, crucial for pest management.
Host plant resistance involves plants naturally deterring or tolerating insect pests, reducing reliance on chemical pesticides, and promoting environmental sustainability. Allomones benefit the emitter in interspecies communication, while kairomones benefit the receiver. Ecdysone regulates molting and metamorphosis in insects, influencing pest control strategies. Attractants lure pests away from crops, aiding in pest management. Chaffy ear refers to a malformed ear in grains due to pest infestation. Economic threshold level is the pest density at which control measures should be implemented to prevent economic damage. Transgenic plants engineered for pest resistance reduce pesticide usage. Ecological control involves using natural predators or habitat management to manage pests. IPM is knowledge-intensive due to its reliance on understanding pest biology and ecology. Cultural control alters farming practices to reduce pest establishment, while mechanical control uses physical methods to remove pests. Pest Risk Analysis assesses potential risks associated with pests moving through trade. Monitoring involves tracking pest populations to implement timely control measures.

More Information
Host plant resistance is a key strategy in integrated pest management (IPM), providing a sustainable alternative to chemical methods. Allomones and kairomones play important roles in ecological interactions among different species.
Tips
Common mistakes include confusing the definitions of allomones and kairomones and overlooking the role of host plant resistance in reducing environmental impact.
