|Title:||Effective Use of Two Biological Insecticides for the Control of 'Helicoverpa armigera' on Cotton||Contributor(s):||Balfe, Marjorie Elaine (author); Gunning, Robin (supervisor); Gregg, Peter (supervisor) ; Stanley, John (supervisor); Jessop, Robin (supervisor)||Conferred Date:||2012||Copyright Date:||2011||Handle Link:||https://hdl.handle.net/1959.11/11384||Abstract:||Insecticide resistance in 'Helicoverpa armigera' (Hübner) (Lepidoptera: Noctuidae) poses a constant challenge to cotton production in Australia. This thesis focuses on resistance to two biological insecticides, pyrethrum and spinosad. Both could be highly effective insecticides if resistance in 'H. armigera' were not a problem. The purpose of this work was to investigate metabolic resistance mechanisms to pyrethrum and spinosad and to determine whether resistance could be overcome by temporal synergism using novel techniques of pre-spray synergist applications of the esterase inhibitor piperonyl butoxide (PBO).||Publication Type:||Thesis Masters Research||Field of Research Codes:||070603 Horticultural Crop Protection (Pests, Diseases and Weeds)||Rights Statement:||Copyright 2011 - Marjorie Elaine Balfe||HERDC Category Description:||T1 Thesis - Masters Degree by Research||Statistics to Oct 2018:||Visitors: 295
