Impact Of Predators On Hemlock Woolly Adelgid (Hemiptera: Adelgidae) In The Eastern And Western United States, Ryan Crandall
Impact Of Predators On Hemlock Woolly Adelgid (Hemiptera: Adelgidae) In The Eastern And Western United States, Ryan Crandall
Masters Theses
Hemlock woolly adelgid, Adelges tsugae, native to Asia and the Pacific Northwest of North America (Pacific Northwest), has devastated eastern hemlock (Tsuga canadensis) in a major portion of its range in the eastern U.S. After many years and much effort directed towards rearing and releasing biological control agents to manage HWA, one of these agents, Laricobius nigrinus, native to the Pacific Northwest, is now well-established in sites from the southern to the mid-Atlantic states of the eastern U.S. However, there have yet to be studies of its efficacy in lowering A. tsugae densities, and there has …

Insights From Population Genomics To Enhance And Sustain Biological Control Of Insect Pests, Arun Sethuraman, Fredric J. Janzen, David W. Weisrock, John J. Obrycki

Biological control—the use of organisms (e.g., nematodes, arthropods, bacteria, fungi, viruses) for the suppression of insect pest species—is a well-established, ecologically sound and economically profitable tactic for crop protection. This approach has served as a sustainable solution for many insect pest problems for over a century in North America. However, all pest management tactics have associated risks. Specifically, the ecological non-target effects of biological control have been examined in numerous systems. In contrast, the need to understand the short- and long-term evolutionary consequences of human-mediated manipulation of biological control organisms for importation, augmentation and conservation biological control has only recently …
Arcola Malloi (Pastrana), The Alligatorweed Stemborer, A New Synonym Of Macrorrhinia Endonephele (Hampson) (Lepidoptera: Pyralidae: Phycitinae), James E. Hayden, Jean-François Landry
Arcola Malloi (Pastrana), The Alligatorweed Stemborer, A New Synonym Of Macrorrhinia Endonephele (Hampson) (Lepidoptera: Pyralidae: Phycitinae), James E. Hayden, Jean-François Landry
Insecta Mundi
Arcola malloi (Pastrana, 1961) is a junior subjective synonym of Macrorrhinia endonephele (Hampson, 1918) syn. nov. (Lepidoptera: Pyralidae). The species is a biological control agent introduced in United States and Australia to control alligatorweed, Alternanthera philoxeroides (Mart.) Griseb. (Amaranthaceae). The synonymy is recognized by comparison of type specimens, genitalic dissections, and DNA COI barcoding. Vogtia Pastrana, 1961 syn. nov. and Arcola Shaffer, 1995 syn. nov. are synonymized with Macrorrhinia Ragonot, 1887. Macrorrhinia megajuxta (Neunzig and Goodson, 1992) comb. nov. is transferred from Ocala Hulst, 1892. Lectotypes are designated for Divitiaca ochrella Barnes and McDunnough, 1913, and Divitiaca simulella Barnes and …

Stink bugs (Hemiptera: Pentatomidae) are agricultural pests of increasing significance in the North Central Region of the United States, posing a threat to major crops such as soybean. Biological control can reduce the need for insecticides to manage these pests, but the parasitism of stink bugs byTachinidae (Diptera) is poorly characterized in this region. The objective of this study was to evaluate the rate of parasitism of stink bugs by tachinids over 2 yr from nine states across the North Central Region. Parasitism was assessed by quantifying tachinid eggs on the integument of stink bug adults. Parasitism rates (i.e., percent …
Improving The Biological Control Of Persicaria Perfoliata (Polygonaceae) Using Rhinoncomimus Latipes Korotyaev (Coleoptera: Curculionidae), Jaewon Kim
Graduate Theses, Dissertations, and Problem Reports
Persicaria perfoliata (L.) H. Gross (Polygonaceae; Mile-a-minute weed) is a rapid-growing invasive vine introduced from eastern Asia to northeastern United States in the 1930s. This vine has been invaded in disturbed areas and reforestation sites in 15 states in the U.S. and forms dense, monocultural patches that may inhibit natural forest regeneration. To control this weed, a host-specific biocontrol agent, Rhinoncomimus latipes Korotyaev (Coleoptera: Curculionidae) has been released in the P. perfoliata invaded states in the U.S. during the past 15 years. Currently, R. latipes is released by hand to the invaded area where the presence of the weed is …
Identification And Characterization Of Epigenetic Regulators In The Yellow Fever Mosquito, Aedes Aegypti, Shankar C. R. R. Chereddy
Identification And Characterization Of Epigenetic Regulators In The Yellow Fever Mosquito, Aedes Aegypti, Shankar C. R. R. Chereddy
Theses and Dissertations--Entomology
Due to the increased interactions between the sylvatic and urban cycles of Aedes aegypti life cycle, there has been an increase in the incidence of vector-borne diseases. The risk involved through the transmission of viruses like Dengue, Zika, Yellow-fever and Chikungunya calls for an effective control method for the deadly vector. The possibility of pesticide resistance and the costs involved in producing new pesticides have pushed Sterile Insect Technique (SIT) into prominence. However, current methods used to sterize insects for SIT are not highly efficient. This study tackles current issues in mosquito control by identifying and characterizing epigenetic regulators that …
