If there is an excessive amount of "muck" or dead vegetationat the bottom of the lake or pond, which can sometimes occur in settings that are conducive to the parrot feather growth, you can use AquaClear Pellets in conjunction with the Aquacide Pellets to help clear the sediment from the treatment site.  If you decide to use the AquaClear Pellets, they can counteract the Aquacide so we recommend waiting three weeks after treating the parrot feather before switching to weekly applications of the AquaClear. Though very little research has been done on the matter, it is believed that prior to the introduction parrot feather in the 19th century, Phytobius vestitus, a native species, fed on variable leaf milfoil (Figures 5, 6) due to similarities in the growth form between this plant species and parrot feather [4, 10]. Adult females of P. vestitus lay yellow eggs on the leaves and buds of the plant (Figure 2). Little is known about the distribution of Phytobius vestitus. [11] Sutton, D.L. Invasive Species - (Myriophyllum aquaticum) Watch List - Prohibited in Michigan Parrot feather has spikes of stiff, feathery leaves that grow in whorls of 4-6. Another method of controlling Parrots feather is by the usage of herbicides. Proceeding, First International Symposium on Watermilfoil (Myriophyllum spicatum) and Related Haloragaceae Species.

Influence of Myriophyllum aquaticum cover on Anopheles mosquito abundance, oviposition, and larval microhabitat. However, reports of this weevil from museum records and in literature suggest that these weevils are found throughout the temperate regions of eastern North America, with these insects being reported as far west as Oklahoma, as far north as Michigan and New Brunswick, Canada, and as far south as central Florida (Figure 4) [6, 8]. Natural control of parrot’s feather through insects such as Lysanthia flavipes and Listronotus marginicollis are known to damage the plant in its native range and have had some success in South America. web@agcenter.lsu.edu, 106 Martin D. Woodin Hall Aquatic weeds in Africa and their control. 161-178. Control with herbicides is difficult because the emergent stems and leaves have a waxy cuticle that repels herbicides. U.S. Geological Survey, Nonindigenous Aquatic Species Database. Once the weevils have pupated, they chew small holes through the side of the stem to exit the pupation chamber as fully formed adults (Figure 3). Learn about all the Commonwealth's breeding bird species in the Breeding Bird Atlas 2. [5] Couch, R., and Nelson, E. (1985). Biological Control in IPM Systems in Africa. When they preen, these feathers break down into a white or grey powdery dander. Although several insects have been suggested as potential control agents for parrot’s feather (e.g. Though this is a promising discovery, more research needs to be done to determine the host range of the weevil, its efficiency as a biological control agent, and other factors influencing the survival of parrot feather throughout the growing season before this weevil can be used as a management tool for this invasive aquatic weed.

They will tunnel through the stem while they feed and search for an adequate pupation site (Figure 3). Pond Dye can be used to limit sunlight into the pond. (1954). Psittacine beak and feather disease, caused by the circovirus, directly affects the feathers of a parrot. In Neuenschwander, P., Borgmeister, C., and Langewald, J. Phytobius vestitus is a small beetle native to North America that feeds on watermilfoils. One of the most distinguishing features of this weevil is a small, oval-shaped, lightly colored marking on its back near the head [10] (Figure 1).

During the spring of 2019, feeding damage from these weevils seemed to drastically reduce the density of parrot feather, nearly eradicating all emergent stems by midsummer (Figure 11). If using glyphosate formulated for aquatic use plus a surfactant, apply during the low water levels of summer and fall for more complete coverage. the stem-boring weevil Listronotus marginicollis has been found to show a feeding and host preference for parrot’s feather, often killing its terminal bud (Oberholzer et al. This species differs from other Milfoils by having its foliage partially out of the water. [13] Wersal, R.M., Baker, E., Larson, J., Dettloff, K., Fusaro, A.J., Thayer, D.D., and Pfingsten, I.A. Thirty-six days after application, control of parrot’s feather plants by 2,4-D (4–100%, visual assessment with 0% corresponding to no control and 100% to complete control) was higher than control by diquat (53–54%) in 11 out of 12 comparisons, control by glyphosate (34%), and control by imazapyr (8.5%).

Parrot Feather scientific name is Myriophyllum aquaticum. Once they have found the perfect pupation site, the larvae will create a chamber within the stem and begin to pupate (Figure 3). They have been kept as cage birds since ancient times, and they have always been popular because they are amusing, intelligent, and often affectionate.
