Topic: Thyridopteryx


In the News (Sat 28 Nov 09)

  
  Eastern Red Cedar
Your cedar may be "decorated" with little silk sacks that have the cedar's own scaly foliage attached on the outside of them.
These are made by the larvae of a moth called the Bagworm Moth, [Thyridopteryx ephemeraeformis] which feeds on the foliage and uses its little sack as camouflage from predators.
If it was inhabited by a male, the remains of his pupal skin (a dark, crisp shell) may still be hanging out the bottom of the bag.

Cronin, J.T. Inverse density-dependent parasitism of the bagworm, Thyridopteryx ephemeraeformis (Lepidoptera:Psychidae).
Parasitism of Thyridopteryx ephemeraeformis by the Ichneumonid Itoplectis conquisitor was studied on eastern redcedar (Juniperus virginiana) in Virginia during 1986.
Case attachment behavior of final-instar larvae of Thyridopteryx ephemeraeformis on redcedar (Juniperus virginiana), white pine (Pinus strobus), and fl locust (Robinia pseudoacacia) was studied in the field in Virginia during September-October 1983 and 1984.

The four synonyms followed by their present status are as follows: (1) Thyridopteryx vernalis Jones = T. ephemeraeformis (Haworth); (2) Oiketicus bonniwelli Barnes and Benjamin = O. townsendi townsendi Townsend; (3) Oiketicus dendrokomos Jones = O. townsendi dendro-komos Jones; and (4) Platocoeticus jonesi Barnes and Benjamin = Crypto-thelea gloverii (Packard).
Thyridopteryx meadi H. Edwards and Oiketicus townsendi Townsend (with two subspecies) are not discussed because of the author's unf amiliarity with these two species.
Thyridopteryx ephemeraeformis (Haworth), the evergreen bagworm, is quite common over most areas of the eastern United States, frequently becoming a local economic pest on various species of evergreens.

 Bagworms
It is time to be thinking about dealing with bagworms (Thyridopteryx ephemeraeformis) in southern and central Illinois.
Bagworms attack a wide range of evergreen and deciduous trees and shrubs (128 plant species), including arborvitae, juniper, eastern red cedar, spruce, fir, pine, maple, box elder, linden, crab-apple, hackberry, oak, and fl locust.
Parasitism of male bagworms is generally greater than of females, as parasitic wasps tend to locate on the bottom of trees.

Damaging infestations of mimosa webworm (Hyphantria cunea) and the common bagworm (Thyridopteryx ephemeraeformis) occurred this season in various areas of Ohio, with bagworm populations being primarily concentrated in southern and central Ohio.
Although ailanthus webworms are capable of defoliating their odoriferous namesake, such damage is rare, and the insect is usually of little consequence.
The common bagworm, Thyridopteryx ephemeraeformis, once again developed damaging populations in many areas of Ohio this season.

Bagworm (Thyridopteryx ephemeraeiformis) is a serious defoliator of coniferous and deciduous landscape plants in the middle and southern portions of the Midwest.
Young caterpillars are especially difficult to detect on conifers because they live in a silken bag covered with freshly cut foliage.
Applying the nematodes during periods of high relative humidity is critical to this process.
