In what ways are detrimental insects controlled? What is integrated pest management?

Expert Solution

Step 1

Detrimental insects are the species that cause damage to humans and their livestock, crops, and possessions worldwide. Some are direct pests which attack the body of the host or suck sap, suck blood, or eat the tissues. Some are an indirect pest that is concerned with the transmission of pathogens or parasites that causes diseases. Some detrimental insects are- Aphids, American oil beetle, Assassin bug, the bed bug, and many more.

Step 2

Detrimental insects need to be controlled to regulate and manage them as they impact adversely on human activities. There are various methods adopted to control the detrimental insects like:

The sterile male approach is used effectively in eradicating screwworm flies.
Using toxins that are produced by bacteria the Bacillus thuringiensis, a biological control method that is effective in controlling Lepidopteran pests.
The broad-spectrum insecticides can be used to kill detrimental insects.
Producing genetically modified crops that have genes and can express proteins toxic to specific insect pests, for example, Bt cotton.
