There are three primary methods of using biological control in the field: 1) conservation of existing natural enemies, 2) introducing new natural enemies and establishing a permanent population (called “classical biological control”), and 3) mass rearing and periodic release, either on a seasonal basis or inundatively.
Often, the natural enemies are found in the home range of the invasive pest. Some notable examples of classical biological control include the use of decapitating flies (several Pseudacteon species) against red imported fire ants, and a group of flea beetles, thrips, and stem borers used against alligator weed.
Biological control (biocontrol) involves the reduction of pest populations through the use of natural enemies such as parasitoids, predators, pathogens, antagonists, or competitors to suppress pest populations.
Do you think preventing the introduction of invasive species is preferable than trying to control them? Why or why not? Yes because if u prevent it in the first place u will never have to control it.
In fact, the study, published by the journal Nature, finds that for much of human history on the continent, human populations grew like an invasive species, which are regulated by their environment as they spread into new places.
Are invasive species always bad? Maybe not, according to an increasingly common point of view among ecologists. A non-native species is defined as invasive if it causes substantial harm in its new range; just because a species is introduced by human action does not automatically make it invasive.
Invasive species are sometimes trapped, poisoned, and shot in large numbers to save native species from extinction. Some scientists say the bloodshed isn’t worth it.
We should avoid speeding up the extinction of wild species because of the ecosystem and economic services they provide, because it can take millions of years for nature to recover from large-scale extinctions, and because many people believe that species have a right to exist regardless of their usefulness to us.
Biodiversity. Habitat loss and invasive plants are the leading cause of native biodiversity loss. Invasive plant species spread quickly and can displace native plants, prevent native plant growth, and create monocultures.
Here are someways to accomplish this.
The fastest, most effective way to kill roots is with chemical herbicide, as soon as the tree has been cut down.

How to Cut Tree Roots Without Killing the Tree
Glyphosate is best for herbaceous vines. The more serious commercial mixes with 2,4-D and Banvel can eradicate the vine but are more dangerous to work with and can possibly harm the soil. Herbicides are non-selective, so cover any healthy plants you want to keep with a tarp before you apply it.
Select a herbicide made with glyphosate, imazapyr, triclopyr, or some combination of these chemicals, all of which target the ivy roots. Ortho GroundClear Vegetation Killer (view on Amazon) works well for the purpose. If you prefer a more natural approach, you can substitute vinegar in a large spray bottle instead.
Cut perennials off at their roots with a hoe. Remove all plant foliage, and then cover the ground with landscape fabric or black plastic. Weigh the material down with stones or bury the edges under soil to keep it in place on windy days.
Dip a paintbrush in glyphosate herbicide. Paint the exposed lengths of invasive ground cover with the herbicide. Monitor the vines over the next few weeks looking for new growth to emerge. Cut new growth with the pruning shears and apply glyphosate to the vine.
Dispose of all plant debris in trash cans or above the waterline on dry land. Utilize invasive species disposal stations when possible. Dried plant material can be burned. If you need to remove the plant material off site, bag and dispose of it at your local landfill.
