Milfoil Weevil as a Barrier to Invasive Milfoil

September 4th, 2009 by bestmortgageratetips Leave a reply »

The Milfoil  weevil is a little water bug that could be able to rescue suffering ecosystems. This stems  from the fact that it only eats milfoil and is harmless to humanity).
 
In the U.S., there are  two sorts of milfoil. One is indigenous and the other  invasive (Eurasian Milfoil). indigenous milfoil is simply bothersome, but the predatory species is a menace to all  bodies of water in North America. Eurasian Milfoil is the reason the milfoil weevil is so significant.  
 
Eurasian Milfoil (the primary milfoil that will be referenced from  this point on) probably came to America between the 1800’s and the 19404’s as an unwanted  passenger on some large ship. Milfoil can easily travel on the undersurface of a ship and  grow quickly, which causes damaging ecological changes and causes problems for mankind.   Gratefully the milfoil weevil can be spread the same way.
 
  Milfoil spreads fast, which results in less growth for native plants, less food for  some beasts and less living habitat for small marine creatures.  The large mats it forms reduce the oxygenation of water by wind that leads  to stressed fish and algae blooms.
 
For humanity, it reduces the recreational uses of the water by swimmers, boaters, and  fisherman.   Communities are more adversely affected  as the mats can foul intake and overflow pipes ensuing in flooding or droughts.   The mats can be particularly damaging to dykes by breaking or clotting generators and  reducing power yield.  
 
The milfoil weevil may  well be the answer to this plant epidemic.   The milfoil weevil favors Eurasian milfoil to the indigenous variety, which  means that the invasive species are destroyed over time and native floras are allowed to  gradually recover. Coupled with a high breeding rate, the  weevil is the safe and ideal solution to the milfoil problem.   The weevils are a clear solution to the milfoil problem, peculiarly considering the rate  at which the flora spreads.  
 
This water flora spread quickly because broken bits can sink to the bottom and easily form new floras. Aquatic  harvesting devices are not successful because they break the plant and bits come off and  replant themselves elsewhere. Vacuum dredging is a  small better in that it gets the small pieces, but cause a great deal of water  disruption and leaves the bottom bare, so it will need replanting with native species.
 
  With a taste for Eurasia milfoil rather than the indigenous milfoil, the weevil eats the flora  from the inside out, finally destroying the whole plant. Weevils  have a short life, living no more than thirty days, so before the winter comes, three  generations will live and die before they come ashore for the winter. Although they have wings they have rarely been know to fly so no one know if milfoil weevils fly to land or swim.   Once based in a habitat, the milfoil weevil will live even through the coldest Minnesota winters.
