The Effect of Introducing a New Species to the Indigenous Population in an Environment

The Effect of Introducing a New Species to the Indigenous Population in an Environment

There are numerous amounts of ways and examples of when people have

used Biological Control. This occurs when living organisms, such as

predators, pathogens and parasitism are used to control pest insects,

weeds, or diseases. This typically involves some human activity. There

are many different examples worldwide of how people have used

biological control. There are many advantages to using biological

control but also many disadvantages. It is not always the best idea to

move an animal from its habitat to another area. This is mainly

because it would not have its usual prey and would adjust to feed on

other living animals around it.

An example of biological control is the 'killer toad.' It was a

predator brought from Australia to South Ameria to feed on the sugar

cane beetle. Sugar canes fields were being destroyed by the sugar cane

beetles. To put an end to this, the killer toad was brought over. But

this was a terrible mistake. Although the killer toad destroyed of all

the sugar cane beetles, it also allowed itself to prey on other living

organisms. Even though the beetles had been wiped out by the toads,

the toads themselves were still

alive. They are spontaneous eaters and will eat anything they can fit

in their mouths, including insects, frogs, lizards, snakes and small

marsupials. They invaded wetland habitats and competed with the native

frogs. And their shoulders enable them to squirt a highly toxic venom

from a considerable distance, they poison anything that eats them,

including domestic pets.. For example, a dog can die 15 minutes af...

A minute wasp, Encarsia formosa, parasitizes white flies exclusively.

The wasps have been known to be very effective in greenhouses. White

flies are attracted to the color yellow. Large numbers of white flies

are trapped when a yellow board is sprayed or painted with any sticky

substance and placed in the vicinity of the pests.

These are just a few examples of how a new species added to an

indigenous population can prove change. In this case I have portrayed

the advantages and disadvantages of different species moving to other

environments and it can lead to the destroying of unappreciated

species however, they will eventually stay and another species

occupying the field. Therefore I conclude that the environment will

always be affected if a new species is introduced in and indigenous

population.
