Some Invasive species may not be entirely bad
alien species are established in the U.S., and a 2005 study put the
economic and environmental costs at $120 billion a year
Environmental scientists are using carefully selected predatory wasps,
beetles, flies, fungi and fish in hopes of controlling an increasing
number of invasive species threatening Connecticut's natural landscape.
Tens of thousands of wasps from China have been released to help control
the Emerald ash borer. One of the wasps being released lays its
parasitic eggs inside the emerald ash borer's larva, while the other
attacks the beetle's eggs directly. The two species of Chinese wasps had
to undergo years of screening and testing to make certain they would
only attack the emerald ash borer and not start slaughtering native
North American insects. The wasps are harmless as far as humans are
concerned. A Japanese fungus is being used to attack gypsy moths.
European parasitic techinid flies have been launched against a new
threat from winter moths. And Asian grass carp are mowing down invasive
watermilfoil in places like Candlewood Lake and Ball Pond in New
One of the most infamous examples involved Australia's cane
toad experiment. The poisonous toad was introduced from the Americas in
1935 to counter beetle infestations in sugar cane fields. The toxic
amphibians now number in the millions, have killed off various native
Australian reptiles and are considered a major pest.
loosestrife, an attractive flowering invasive introduced in North
America from Europe, has been crowding out native species for something
like two centuries. It wasn't until 1986 that scientists in Europe began
using the Galerucella leaf-eating beetle as a way to control purple
loosestrife, and it took another seven years before the beetle was allowed
to be released in the U.S.

Florida is home to an estimated 1.3 million
gators. They grow to an average adult size of 8.2 ft for female
alligators and 11.2 ft for males. There have only been 24 fatal
alligator attacks in Florida since the Florida Fish and Wildlife
Conservation Commission began keeping records in 1948. Alligators can
lunge towards you at speeds of more than 20 m.p.h..

Asian Carp Threat to the Great Lakes
keep invasive bighead, silver, and black carp out of the Great Lakes.
is an invasive species that has been established in
many Mediterranean climate areas, inadvertently introduced by humans to
many places, including South Africa, New Zealand, Japan, Easter Island,
Australia, Europe, Hawaii, and the continental United States.
Helicoverpa Armigera (Bollworm)
is part of the order of Lepidoptera and is the larval
(see caterpillar) life stage of a fall armyworm moth. It is regarded as
a pest and can wreak havoc with crops if left to multiply. Its name is
derived from its feeding habits. Native to Americas, these caterpillars
mainly attack maize crops. They will eat everything in an area, and once
the food supply is exhausted, the entire "army" will move to the next
available food source.
