What is the Milfoil Weevil? Is it Found in Momeyer North Carolina


The eurasian water milfoil weevil (Euhrychiopsis lecontei) is known as an eco-friendly vegetation killer of some types of milfoil and has been take a look at carefully by research scientists as a natural control for water milfoil over of 2 whole years. Generally since weevils are generally found in Momeyer, North Carolina United States fish ponds having eurasian watermilfoil issues, the probabilities are great that they presently occupy your pond. Yet, as a result of the truth watermilfoil will certainly expand so rapidly, 100% natural populaces of weevils simply can not normally manage it. Therefore one method is to simply elevate the organic milfoil weevil population to lasting amounts enough to efficiently handle the eurasian water milfoil over the long-term.

What exactly is biocontrol? All-natural control, or biocontrol, is considered the procedure associated with breeding then releasing all-natural enemies (predators as well as parasites) of different other microorganisms which are considered as parasites (hosts). A reliable biocontrol representative is rather targeted to one or perhaps a few hosts which’s why, these natural control agents have the tendency to be completely safe to individuals and also do not cause harm to the real atmosphere. They merely enhance the all-natural balance of mother earth. Continue to keep in mind, nevertheless, that biocontrol does not completely remove these unwanted parasites; it keeps them at reduced degrees where they aren’t thought to be a nuisance.
Exactly how precisely does the milfoil weevil influence eurasian water milfoil in Momeyer?

Organic control microbes in fact decrease their host plants. Not only does the weevil rely on the vegetation for nutrients, but furthermore finishing every one of its living phases. Equivalent to a butterfly, the weevil’s life-span stages have an egg cell, larvae, pupa, then mature phase. When adults, they’ll eat the eurasian water milfoil, however additionally look for lively watermilfoil tips (referred to as the meristem) to lay eggs. When the eggs hatch out to larvae, the larvae passage down with the whole stem developing ports in the stem walls while it goes in and out and hollows out the stem tissue. This sort of indoor devastation hinders all the supply of nutrients throughout the plant as well as the origins, where power is preserved for following years’ growth. Furthermore, holes within the stem created by the larvae enable gas to leave as well as make the plant to lose buoyancy in the water. When the stem is struck by the weevil and afterwards dies, it starts to tip over as well as bear down nearby stems, pulling them additionally from the lake surface area. This opens the plant cover and also allows wanted indigenous plant to complete better, and also at some point replace the eurasian water milfoil beds.

Most of the times, 3 to 4 extra generations of milfoil weevil’s need to continue and multiply as well as spread out throughout the body of water in a season. Inevitably, as the watermilfoil reduces within the dealt with body of water, the beetle number gradually declines to a self-sufficient degree.

Precisely just what results can be expected while utilizing the eurasian watermilfoil weevil? On the whole, the objective is to construct a longer term people of the milfoil weevil’s which will persistently control the eurasian water milfoil for many years to come. Combating large milfoil troubles could be challenging with out a particular weevil-stocking strategies to optimize success. This includes stocking rather great deals of weevils in numerous places over 2-3 years usually, depending upon the range of infestation. We likewise understand that stocking additional weevils in the initial year raises the price related to lake-wide control.


Desired control using the weevil typically takes between 2 or 3 years usually. Control entails:

  • Significant reduction in water milfoil density, and in most cases reduction of mostly all eurasian watermilfoil beds;
  • Maintenance of the enduring plants listed below the water’s surface area at non-nuisance arrays;
  • Aid to enhance of indigenous plant life kinds and also re-establishment of a diverse native plant neighborhood within areas once covered with milfoil.
