Our highly seasonal world restricts insect activity to brief portions of the year. This feature necessitates a sophisticated interpretation of seasonal changes and enactment of mechanisms for bringing development to a halt and then reinitiating it when the inimical season is past. The dormant state of diapause serves to bridge the unfavourable seasons, and its timing provides a powerful mechanism for synchronizing insect development. This book explores how seasonal signals are monitored and used by insects to enact specific molecular pathways that generate the diapause phenotype. The broad perspective offered here scales from the ecological to the molecular and thus provides a comprehensive view of this exciting and vibrant research field, offering insights on topics ranging from pest management, evolution, speciation, climate change and disease transmission, to human health, as well as analogies with other forms of invertebrate dormancy and mammalian hibernation.

Nontarget Effects of Biological Control is the first book of its kind. The environmental safety of biological control has come under scrutiny due to several areas of concerns: the irreversibility of alien introductions, the prevalence of host switching to innocuous native or beneficial species, dispersal of the biocontrol agent to new habitats away from croplands, and the lack of research on the efficacy and impact of biocontrol attempts. The debate has been strongly polarized between conservationists and biological control practitioners. Nontarget Effects of Biological Control proposes that retrospective analyses of systems in place in which nontarget effects are now documented or suspected provide the necessary information for planning and evaluating future releases to reduce risk. The book presents case histories of past biological control introductions from island and continental ecosystems.

Easily Use SAS to Produce Your Graphics Diagrams, plots, and other types of graphics are indispensable components in nearly all phases of statistical analysis, from the initial assessment of the data to the selection of appropriate statistical models to the diagnosis of the chosen models once they have been fitted to the data. Harnessing the full graphics capabilities of SAS, A Handbook of Statistical Graphics Using SAS ODS covers essential graphical methods needed in every statistician’s toolkit. It explains how to implement the methods using SAS 9.4. The handbook shows how to use SAS to create many types of statistical graphics for exploring data and diagnosing fitted models. It uses SAS’s newer ODS graphics throughout as this system offers a number of advantages, including ease of use, high quality of results, consistent appearance, and convenient semiautomatic graphs from the statistical procedures. Each chapter deals graphically with several sets of example data from a wide variety of areas, such as epidemiology, medicine, and psychology. These examples illustrate the use of graphic displays to give an overview of data, to suggest possible hypotheses for testing new data, and to interpret fitted statistical models. The SAS programs and data sets are available online.

Jointly published with INRA, Paris. Pesticide resistance is becoming more frequent and widespread with more than 500 insect species known to have become resistant to synthetic insecticides. On the other hand, consumers increasingly demand agricultural products without any pesticide residues. This book, for the first time, shows the alternative: solely physical methods for plant protection by means of thermal, electromagnetic, mechanical and vacuum processes. A glossary rounds up this extremely valuable book.
