Vector biology has become a fast moving field. Spurred on by the recent exciting advances in the molecular biology, genomics and latterly proteomics of vector insects and their pathogens, researchers are using new approaches and our knowledge is rapidly increasing. The second edition of this volume very much reflects these advances. The editor, William Marquardt, has assembled a team of section editors to oversee the production of 57 short chapters, divided into 7 parts. With a few exceptions, these experts are drawn from the USA, a reflection no doubt of the history of the first edition which was produced to accompany the Biology of Vector Disease course, given at Colorado State University. The text is aimed at post-graduate and post-doctoral researchers, working in a range of areas associated with vector biology and vector-borne diseases. It provides an excellent opportunity to obtain an initial overview of a new area or to dip into a field that may be peripheral to the topic under investigation.

Ascaris suum and Ascaris lumbricoides exhibit an over-dispersed frequency distribution in their host populations in both the adult and larval stages. The impact of host factors on this observed distribution is still poorly understood and difficult to investigate in the natural host populations. The use of a mouse model has been supported by the observations that the larval migratory pattern, in this host, mimics the pattern observed in the pig. We explored the extrinsic factors that might affect the quantitative recovery of larvae during this migration in order to standardize a model system facilitating accurate future assessment of host genetic variation on this phase of the infection. In Exp. 1 larvae accumulated in the livers of both C57BL/6j and BALB/c mice up to and including days 4–5 p.i. and then declined in both strains until day 9. Loss of larvae from the livers corresponded to arrival in the lungs and maximum accumulation on day 7 p.i. but recovery was considerably higher in C57BL/6j mice. It was concluded that day 7 recoveries gave the best indication of relative resistance/susceptibility to this parasite. In Exp. 2 A/J, BALB/c, CBA/Ca, C57BL/6j, C3H/HeN, DBA/2, NIH, SJL, and SWR mice were compared. C57BL/6j mice were identified as the most susceptible strain and CBA/Ca mice as having the most contrasting phenotype, but with a similar kinetic pattern of migration. Finally, in Exp. 3, a strong positive correlation between the size of the inoculum and the mean worm recovery from the lungs was found in CBA/Ca and C57BL/6j mice, but the difference between these strains was highly consistent, 66·6–80%, regardless of the initial dose. These results demonstrate that, using our protocols for infection and recovery, between-experiment variation in A. suum worm burdens is minimal, and that C57BL/6j mice are highly susceptible to infection compared to other strains. The mechanistic basis of this susceptibility in relation to the resistance of other strains is unknown, but the possibilities are reviewed.

Trematodes (flukes or digeneans) are by far the most abundant group of parasitic flatworms (Neodermata), and their importance for human and animal health is indisputable. In addition, they exhibit a variety of unique adaptations to parasitism and, probably most remarkably, possess extraordinarily complicated life-cycles. Classification of trematodes represents a very difficult task due to the huge number of existing species and variety of morphological forms, sites of infection within invertebrate and vertebrate hosts and ability to infect a wide spectrum of animals. Therefore, identification of any trematode may represent a problem even for an experienced specialist. This is the reason why I appreciated so much the publication of the first volume of the Keys to the Trematoda in 2002.

Fish parasitology has become an enormous field. The preface to this volume explains that the scope has been trimmed by focusing on those parasites most likely to be encountered by aquarists, anglers and naturalists – the external parasites; this approach excludes tapeworms, nematodes and most protozoans. The examples are mainly taken from the British fauna, but readers from other regions will find the subjects familiar.

This book is dedicated to my Ph.D. advisor, Neil Croll (1941–1981), whose seminal text “The Behaviour of Nematodes” launched the field in 1970. The current effort is a thick, heavy tome when compared to Croll's slim and elegant little book, directly reflecting the explosion of interest in the topic, due in no small part to a single nematode Caenorhabiditis elegans. However, C. elegans is not the star of this book. The present effort is meant to be broad in its taxonomic scope, attempting to consolidate disparate nematode behaviours into a comprehensive up-to-date volume. Indeed, this is a formidable task in a world in which 4 out of every 5 metazoans is a nematode, and the end result is a bit uneven. To cover the taxonomic breadth, several chapters focused on simply describing proximate behaviours. Thus, Chapter 1 – Ecological and behavioural adaptations; Chapter 3 – Orientation; Chapter 4 – Feeding; Chapter 7 – Osmoregulation; and Chapter 8 – Physiological and biochemical basis of behaviour, were generally not synthetic, and read like catalogues of behaviour descriptors, often with little context on the natural history or biology of the responses. These chapters are not accessible to the non-specialist student, and their value lies primarily in their extensive literature searches. On the other hand, there are several wonderful pieces, including Chapter 5 – Reproductive behaviour and Chapter 6 – Ageing and development, whose compelling and clearly written stories cut across the artificial lines of plant, insect, animal, and parasite designations, to address the essence of our understanding of nematode behaviour. In this group, I particularly liked Chapter 2 – Locomotion, for the succinct incorporation of historical ideas into the growth of current thinking in this area. Chapter 9 – Molecular basis of behaviour, was an excellent presentation of behaviour in the C. elegans model system, and the authors did an outstanding job making the concepts and techniques in this high-tech area accessible to students of general biology. The remaining 4 chapters fell somewhere in the middle of the continuum. Overall, I think this a good effort, and I recommend this book for the shelves of every nematode biologist. It is valuable because of the sheer amount of information on nematode behaviour that it contains, and especially for the reference lists. For the 4 or 5 well-written chapters, this book is priceless!
