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 yellow jackets windbreaker forms reduce the oxygenation of water by wind 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 Nwpss Sale ashore for the winter.Regardless, once there they survive even the harshest minnesota winters.
