Predicting Pests: A History of International Plant Pest Reporting and Risk Analysis
This thesis explores how plant protection experts have tried to work together across national borders to anticipate, and thus prevent, invasive pest problems in agriculture, largely focusing on developments since World War II. It shows how these experts characterised pest invasion as an …

Comparative studies of three aphelinid parasitoids of Trialeurodes vaporariorum (Westwood) (Hemiptera: Aleyrodidae) with emphasis on Eretmocerus eremicus Rose and Zolnerowich : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Plant Protection (Entomology) at Massey University, Palmerston North, New Zealand
… The parasitism study was performed on tomato plant leaf cuttings and the host-feeding study on tomato plant leaf disks. The leaf materials used in these studies were infested with 2nd instar greenhouse whitefly nymphs. To replicate the range of temperatures encountered in a glasshouse, these …

The development of azadirachtin as a soil-applied, granular insecticide
… for root uptake and subsequent systemic plant protection. A method was developed whereby azadirachtin could be rapidly isolated to approximately 95% purity using flash chromatography. This material was used in all subsequent chemical and biochemical studies. To increase the speed of crude …

Assessing the Effects of Chronic Neonicotinoid Insecticide Exposure on Aquatic Insects using Multiple Experimental Approaches
… insecticides are among the most widely used plant protection products in industrialized agriculture, and are hypothesized to be contributing to losses in non-target insect biodiversity. The lack of toxicological data evaluating the effects of neonicotinoids restricts the ability of regulators …

Efficacy of Administrative Monetary Penalties in Compelling Compliance with Federal Agri-Food Statutes
… with the Health of Animals Act and the Plant Protection Act. It does this by critically examining the purposes underlying the omnibus statute, which are to provide a fair and efficient alternative to the existing penal system and to supplement existing penal measures to enforce statutes …
