Assessing the safety of weed biological control : a case study of the cinnabar moth Tyria jacobaeae

Creator:: Fuller, Jason L.
Abstract:: The cinnabar moth, Tyria jacobaeae (L.) (Lepidoptera:Arctiidae), was released in 1959 to control the grassland weed tansy ragwort, Senecio jacobaea L. (Asteraceae), despite evidence that caterpillars of this species can feed on native plants within the genera Senecio and Packera. Previous studies confirmed the moth's ability to develop on the...

An evaluation of biological control of Linaria dalmatica with Mecinus janthinus in Oregon

Creator:: Park, Alexander
Abstract:: Dalmatian toadflax (Linaria dalmatica) has become a prolific invasive plant of rangelands in Oregon since its arrival in the early 20th century. In 2001, the Oregon Department of Agriculture initiated a release program promoting the distribution of the stem-boring weevil, Mecinus janthinus as classical biological control agent to reduce densities...

Biotic barriers to colonizing new hosts by the cinnabar moth Tyria jacobaeae (L.)(Lepidoptera: Arctiidae)

Creator:: Karacetin, Evrim
Abstract:: The cinnabar moth (Tyria jacobaeae (L.), Lepidoptera: Arctiidae) is an icon in population ecology and biological control that has recently lost its shine based on evidence that (1) it is less effective than alternatives (such as the ragwort flea beetle Longitarsus jacobaeae (Waterhouse) (Coleoptera: Chrysomelidae) for controlling ragwort Senecio jacobaea...

Biotic and Abiotic Factors Affecting the Presence of Beneficial Insects on Oregon Christmas Tree Farms

Creator:: Cain, Alyssa B.
Abstract:: Beneficial insects could provide valuable pest control services on Oregon Christmas tree farms, but a limited amount of data exist that quantifies the type and abundance of beneficial insects on farms. This study surveyed beneficial insects on two farms that differed in their management strategies as well as other abiotic...

Evaluating Leucopis species (Diptera: Chamaemyiidae) from the Pacific Northwest as potential biological control agents of the hemlock woolly adelgid (Hemiptera: Adelgidae)

Creator:: Grubin, Sarah M.
Abstract:: Hemlock woolly adelgid, Adelges tsugae Annand, is a destructive introduced pest of hemlock trees in eastern North America, and management has focused on the use of natural enemies through classical biological control. Two species of chamaemyiid flies, Leucopis argenticollis Zetterstedt and Leucopis atrifacies (Aldrich) have been collected previously from western...

Ecology and biological control of an apomictic invasive plant, Chondrilla juncea (Asteraceae)

Creator:: Campanella, Donald M.
Abstract:: A study consisting of three parts was undertaken to investigate how variation in species interactions, population genetic structure, epidemiological parameters, and plant breeding system may influence the ecology and biological control of an apomictic invasive plant, Chondrilla juncea (Asteraceae). Interactions between natural enemy species may modify their net effect on...

Habitat management for beneficial insects on Willamette Valley vegetable and berry farms

Creator:: Russell, Michael C.
Abstract:: Conservation biological control involves manipulating farm landscapes or management systems to enhance populations of beneficial predators of agricultural pests. Farmscaping is one aspect of conservation biological control where predators of important pests are identified, the availability on the farm landscape of resources and habitat components needed by the beneficials to...
