Parrot feather plants grow in fresh water areas from rhizomatous roots. Verdc.]. 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]. Although several insects have been suggested as potential control agents for parrot’s feather (e.g. Baton Rouge, LA 70803 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. Draining a pond in the summer achieved control in one instance, but draining may not achieve control in winter. Within several days, these adults will begin mating and laying eggs, starting the cycle anew. Adult feeding damage on the stem results in characteristic black or dark brown circular scars (see Figure 8). Box 10748, White Bear Lake, MN 55110. (2003). The condition of the building “envelope” directly affects its structural integrity, the degree to which pests can infiltrate it, and the overall condition of the collections housed within. Figure 9. Emersed foliage is bright green. More research needs to be done to determine the full host range, or the range of plant species an insect will feed on, of this weevil before the insect can be used as a biological control agent. (In preparation). The active ingredients that have been successful in treating parrot’s-feather include: 1. 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]. Vicksburg, Mississippi: The Aquatic Plant Management Society, Inc. https://www.apms.org/pdf/1985proceedings.pdf, [12] Wersal, R.M. Little is known about the distribution of Phytobius vestitus. There are many species of watermilfoil found throughout North America [1]. This is a sharp contrast with the other weevil found feeding on parrot feather, Pelenomus canaliculatus, which is uniformly black and does not have this lightly colored spot (Figures 11, 12 of the “Plant Biology and Issues” section) (Dr. Robert Anderson, personal communication, January 22, 2019). Novel host association of Phytobius vestitus (Coleoptera: Curculionidae) on the invasive aquatic weed Myriophyllum aquaticum. Figure 5. Once these eggs hatch, the larvae begin to feed on young, tender leaves on the buds. Mechanical Control Parrot Feather can be removed by cutting and raking from the pond. Being planted either fully submerged or as a marginal plant works just fine for Brazilian watermilfoil. Once an invasive species has established itself in a suitable environment with no natural predators, it is nearly impossible to eradicate the species from the area. Figure 3. Herbicides are the most common and effective means of controlling Parrot feather, but it is difficult to achieve complete control. Figure 7. Checklist.

Adult females of P. vestitus lay yellow eggs on the leaves and buds of the plant (Figure 2). These insects will often pupate below the waterline and might utilize the oxygen stored within the buoyant, air-filled stems of the plant to avoid drowning. Oecologia 90: 474-482. However, there is a possibility that this weevil could feed on other heterophyllous species of watermilfoils, such as cutleaf watermilfoil [10]. If using glyphosate formulated for aquatic use plus a surfactant, apply during the low water levels of summer and fall for more complete coverage. Best results are seen this way due to the availability of space as compared to rapid growth. Late impacts of weevil damage on parrot feather in Gramercy, Louisiana (May 2019). 59-71.

Once they have found the perfect pupation site, the larvae will create a chamber within the stem and begin to pupate (Figure 3). While no bird is immune to this disease, it is more common in African gray parrots, eclectus parrots, cockatoos, ringneck parakeets and macaws. Introductory History Originally native to the waterways of the Amazon Basin, the plant has been distributed to many parts of the world, as an indoor or outdoor aquatic cultivar, for over 100 years. (Eds.) 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%).
