Milfoil weevil as a solution to invasive milfoil The milfoil weevil is a small
water bug that may be able to rescue suffering ecosystems.This little bug may be
very helpful because it eats the invasive plant known as milfoil and poses no
threat to humans. There are two types of milfoil to be found in the us.Eurasian
milfoil is invasive and non-Indigenous and the other is simple indigenous.Native
milfoil is merely annoying, but the offensive species is a menace to all bodies
of water in north america.Eurasian milfoil is the reason the milfoil weevil is
so important. Eurasian milfoil(from this point forward all milfoil will be
considered Eurasian milfoilunless otherwise noted)Was most in all probability
introduced to the united states sometime between the late 1800's to 1940's as
either a stowaway on a ships ballast or discarded shipping material.Milfoil can
easily travel on the undersurface of a boat and grow rapidly, which causes
damaging ecological changes and causes problems for humanity.Luckily this can
spread the milfoil weevil as well. This water flora grows quickly, devastating
local floras and limiting the food and living area for many aquatic beasts.The
large mats it nwpss north face online mens

that leads to stressed fish and algae blooms. For mankind, it cuts the
recreational uses of the water by bathers, boaters, and fisherman.Residential
areas are more adversely affected as the mats can clog intake and overflow pipes
resulting in flooding or droughts.In dams, they clog and break generators and
reduce electricity output. The milfoil weevil may well be the solution to this
flora epidemic.Eurasia milfoil is a favorite of the milfoil weevil rather than
the native kind;This results in the invasive species being step-By-Step
destroyed and indigenous plants slowly returning to their natural place.With a
high breeding rate and a taste for milfoil, the milfoil weevil and a smart and
safe way to remove the unwanted milfoil.The weevils are a clear answer to the
milfoil problem, peculiarly considering the rate at which the plant spreads.
Milfoil spread when a small section is broken off, sinks to the bottom and then
takes root, forming a new growth.Using large aquatic harvesters are not the
answer as the break up the milfoil too much and it grows right back.Vacuum
dredging works a little better because no broken pieces are left behind, but at
the same time the vacuum disrupts the water and may leave no flora nwpss north face online mens blue jackets
waterproof life at the bottom. The milfoil weevil will destroy the whole
flora by digging into the stem and eating from the inside out, which will kill
the plant.With only thirty days to live, the milfoil weevils will go through
three generations before coming ashore for the winter.Milfoil weevils do have
wings, but no one has ever seen them fly so no on knows precisely how the come
