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 | Fields of Research (FoR) 2008: | 070603 Horticultural Crop Protection (Pests, Diseases and Weeds) | Fields of Research (FoR) 2020: | 300804 Horticultural crop protection (incl. pests, diseases and weeds) | Socio-Economic Objective (SEO) 2008: | 820301 Cotton | Socio-Economic Objective (SEO) 2020: | 260602 Cotton | Rights Statement: | Copyright 2011 - Marjorie Elaine Balfe | HERDC Category Description: | T1 Thesis - Masters Degree by Research |
