Microbial control agents targeting soildwelling organisms need to be compatible with commonly used fertilisers The bacterium Serratia entomophila is used as a microbial control agent for control of the New Zealand grass grub Costelytra zealandica and Beauveria bassiana is an entomopathogenic fungus used to control a range of insect pests These biocontrol agents were formulated into granules and applied to pots together with five fertilisers commonly used on pastures throughout New Zealand Compatibility with S entomophila was also assessed in a field trial where treatments were applied by direct drilling and surface application There appeared to be no deleterious effect from the application of the fertiliser treatments on the establishment and survival of either S entomophila or B bassiana On the contrary there was a suggestion that some nitrogenous fertilisers may lead to an increase in numbers of the bacterial biocontrol agent

Storage Characteristics

A granular formulation of Serratia entomophila has been developed to improve shelflife and storage characteristics of this bacterium which is used as a microbial control agent of the New Zealand grass grub Bacterial establishment and survival of bacteria released from the granular and liquid formulations were assessed in a laboratory experiment Bacteria were enumerated by dilution plating onto Serratia selective agar Serratia entomophila populations in soil inoculated with granules remained stable in soil for up to five months at a range of soil moisture levels Bacterial numbers declined more rapidly when soil was inoculated with the liquid formulation High numbers of bacteria remained viable in the granules throughout the experiment demonstrating the potential for sustained release of inoculum after application of the biopesticide granules

Our collaboration involves groups in Denmark, the U.S.A. Spain and of course New Zealand. Combining ground-based and satellite (IUEandHST) observations we aim to determine accurate and precise stellar fundamental parameters for the components of Magellanic Cloud Eclipsing Binaries as well as the distances to these systems and hence the parent galaxies themselves. This poster presents our latest progress.

The Type I simple cold block device was described by Bullivant and Ames in 1966 and represented the product of the first successful effort to simplify the equipment required to do sophisticated freeze-cleave techniques. Bullivant, Weinstein and Someda described the Type II device which is a modification of the Type I device and was developed as a collaborative effort at the Massachusetts General Hospital and the University of Auckland, New Zealand. The modifications reduced specimen contamination and provided controlled specimen warming for heat-etching of fracture faces. We have now tested the Mass. General Hospital version of the Type II device (called the “Type II-MGH device”) on a wide variety of biological specimens and have established temperature and pressure curves for routine heat-etching with the device.

This cytochemical study was designed to investigate early metabolic changes in the aortic wall that might lead to or accompany development of atherosclerotic plaques in rabbits. The hypothesis that the primary cellular alteration leading to plaque formation might be due to changes in either carbohydrate or lipid metabolism led to histochemical studies that showed elevation of G-6-Pase in atherosclerotic plaques of rabbit aorta. This observation initiated the present investigation to determine how early in plaque formation and in which cells this change could be observed.Male New Zealand white rabbits of approximately 2000 kg consumed normal diets or diets containing 0.25 or 1.0 gm of cholesterol per day for 10, 50 and 90 days. Aortas were injected jin situ with glutaraldehyde fixative and dissected out. The plaques were identified, isolated, minced and fixed for not more than 10 minutes. Incubation and postfixation proceeded as described by Leskes and co-workers.
