Question

Which of the following is a physical method of integrated pests management?
A. Humidity
B. Cold
C. Conservation of the native enemy population
D. Both A and B

Answer 1

Hint: Control pests with physical methods or mechanical devices such as knocking pests off of plants with a spray of water, using barriers and traps, cultivating soil solarization, or heat treatments.

Complete answer: Integrated pests management is a method that uses natural agents like microbes and insects to control the population of other harmful pests and insects. The different methods used to control pests contain physical methods, biological methods, chemical methods, mechanical methods, and cultural methods. The physical method involves controlling pests by physical parameters like cold, temperature, humidity, light, etc. Manipulation of these parameters helps in controlling pests using tools or machinery. Harvest practices, Tillage, Grazing, Trap strips, Fire are some types of physical pest control. For farmers, the fire has been a powerful technique used to destroy insect breeding grounds. They are covered in a substance that attracts insects but is actually very sticky or poisonous. These traps are commonly used for flies or leafhoppers.
Hence, the correct answer is Option D.

Note: To state in simple terms that the trap strips are grown for using them as bait for insects which attracts towards normal plants. The insects can be dealt with much more easily than if they were to have been spread throughout an entire field. The sawflies will go only as far as they need to in order to plant their eggs. If solid stemmed plants are planted around the crop field, then that's where the sawflies will go and the sawflies’ larvae can't survive in the solid stem.
