A pan-genomics approach linking genotype and phenotype in the mega-pest, Helicoverpa armigera
… attempts to control it, initially with synthetic pesticides and more recently with Bacillus thuringiensis (Bt) derived bio-toxins. Understanding the genetic mechanisms that drive pesticide resistance is crucial for effective monitoring of resistance but remains challenging. Recent advances in …

Morphological and Physiological Characteristics that Contribute to Insecticide Resistance in Bed Bug (Cimex lectularius L.) Eggs
… and physiology is potentially related to pesticide resistance in bed bug eggs. Bed bug egg morphological features were examined using scanning electron microscopy (SEM) and the chorion and respiration structures were identified. Scanning electron microscopy photographs and bed bug egg …

Spotted-wing Drosophila: Investigating the Efficacy of Innovative and Alternative Management Techniques
… frequent spraying can contribute to insecticide resistance and may even fail to adequately protect fruit from infestation. Organic pesticide application for SWD management is particularly difficult for growers due to fewer chemical options and increased cost compared to conventional products. …

Investigating the potential of South African Entomopathogenic nematodes for the management of Ceratitis capitata (Wiedemann)
… alone. Increasing regulatory pressure, pesticide resistance and the environmental damage associated with synthetic chemicals highlight the need for alternative, sustainable management options that can be integrated into existing integrated pest management (IPM) programs. Among the most …

Adaptation and hybridization in Helicoverpa crop pests
… hybridization, an allele conferring insecticide resistance was introduced into the native Brazilian H. zea population through adaptive introgression. I use this as a system with which to investigate the outcome of secondary contact between native and invasive species. In Chapter 1, I assess the …

Using selected acaricides to manipulate Tetranychus urticae Koch populations in order to enhance biological control provided by phytoseiid mites
… many ornamental plants (Johnson and Lyon, 1991). Pesticide resistance, the high cost of pesticides and loss of production time have raised interest by growers to introduce predatory phytoseiid mites to manage twospotted spider mites and reduce their need for acaricide applications (Sabelis, 1981). …
