This study surveys the population genetic structure of Childers canegrub, Antitrogus parvulus, to elucidate its population dynamics and gene flow. Antitrogus parvulus is a pest of sugarcane in the Bundaberg region and this knowledge can be used to optimise integrated pest management practices. Here, base-pair differences in the cytochrome oxidase II gene (COII) were used to characterise haplotypic diversity, infer levels of gene flow, and phylogenetic relationships of alleles and their phylogeographical structure. There were 28 unique haplotypes among the 70 sequenced individuals from the seven locations. All three variance components (among regions, among populations, within populations) are highly significant, with highest genetic diversity among regions and lowest among populations within regions. A positive correlation between migration rates and geographical distance and significant phylogeographical structure between four main geographical regions. The main implication of these findings for pest management is that if a grower can eliminate an existing infestation within a field, then reinvasion will be slow and further outbreaks within that field are unlikely to occur. The low dispersal ability of females also means that any resistance to insecticides that develops is likely to remain localised, but will rapidly become dominant within the affected population.

This is the first book devoted exclusively to the analysis of the Nazis' radio effort against the United Kingdom during the Second World War. It traces the development of the German propaganda service and looks to erode the myth surrounding Lord Haw-Haw -the 'superpropagandist'. Propaganda is presented in context: the purposes behind it, the changing patterns, themes, styles, and techniques employed, and the impact upon the target audience and its morale. An analysis of the Nazi wireless broadcasts to Britain for the whole of the Second World War reveals a sophisticated and intelligent propaganda assault on the social and economic fabric of British society. In the end the British failed to succumb to the stupefying effects of Nazi propaganda and they traditionally congratulate themselves upon the national unity which immunised them against it. The author argues that this traditional view disguises a more complex, less appealing reality. Free CD Includes a CD of 24 German wartime broadcasts to Britain Key Features: *Exposition of organisational structure of Nazi wireless for the UK *Detailed analysis of style and content of propaganda broadcasts *Careful and critical re-appraisal of British domestic morale and national unity *CD insert of 24 recordings of Nazi broadcasters including William Joyce, John Amery, Edward Dietze, Norman Baillie-Stewart, Edward Bowlby and 'Black' propaganda broadcasts

A novel voltammetric method for simultaneous determination of the glucocorticoid residues prednisone, prednisolone, and dexamethasone was developed. All three compounds were reduced at a mercury electrode in a Britton-Robinson buffer (pH 3.78), and well-defined voltammetric waves were observed. However, the voltammograms of these three compounds overlapped seriously and showed nonlinear character, and thus, it was difficult to analyze the compounds individually in their mixtures. In this work, two chemometrics methods, principal component regression (PCR) and partial least squares (PLS), were applied to resolve the overlapped voltammograms, and the calibration models were established for simultaneous determination of these compounds. Under the optimum experimental conditions, the limits of detection (LOD) were 5.6, 8.3, and 16.8 g l-1 for prednisone, prednisolone, and dexamethasone, respectively. The proposed method was also applied for the determination of these glucocorticoid residues in the rabbit plasma and human urine samples with satisfactory results.
