Management of Pest Insects
Insects and other arthropods are found in nearly every terrestrial and freshwater habitat on the planet. Insect abundance dwarfs all forms of visible life, and makes up more than 75 percent of all known and named animal species. Worldwide, nearly one million insect species have been named, yet entomologists estimate the total number at 2.5-5 million. That means as many as 80 percent of the world’s insect species are undiscovered and yet to be named!
Insects, because of their diversity, display many different lifestyles. Certain insects spend their early life inside the body of another insect, some grow up attached to a river rock, while others spend their entire life in the grass of a front yard. This diversity also means
that some insects are known to consume or damage a wide variety of items important to people. It is not surprising that a few of those one million species can – and will – eat our food, clothing or the wood in our homes. Other insect species may be dangerous, especially those that bite, sting, transmit disease or cause allergies. Many more insects are a nuisance simply because they appear in our living space. Insects then are considered pests for a variety of reasons, and placing them into that subjective category also may justify our attempts at their elimination.
