This book presents the discoveries made during nearly three decades of research on the parental shield bug, Parastrachia japonensis inhabiting Kyushu Island, Japan. P. japonensis has evolved a unique and fascinating life history, characterized by extreme behavioral and physiological adaptations that have culminated in a singularly dependent relationship with its lone host tree, Schoepfia jasminodora (Olacaceae), which is a generally scarce and unreliable resource. It is expected that the evolution of parental care behaviors in the strictly semelparous P. japonensis was more directly influenced by the benefit to females that arises from enhanced survivorship of current offspring, rather than any possible cost the females might incur in terms of reduced future reproductive success, because no future reproduction is possible. The authors explain how the different parental cares in this species enhance offspring survivorship in the context of the ecological conditions it has experienced over evolutionary time. The book begins with a recap of the earliest studies, the reports through 1991, and then introduces the many fascinating aspects of the life history, neurobiology, physiology and behavior of P. japonensis that have been newly discovered since, and those aspects that have been confirmed through experimentation over the past thirty years. This comprehensive review of information will be useful for comparative studies of parental care in other semelparous and iteroparous organisms experiencing both similar and different ecological constraints. The book will be of academic interest to undergraduate and graduate students of entomology, zoology, behavior, and behavioral ecology.

In his exploration of insect societies that don't fit the eusocial schema, James T. Costa gives these interesting phenomena their due. He synthesizes the scattered literature about social phenomena across the arthropod phylum: beetles and bugs, caterpillars and cockroaches, mantids and membracids, sawflies and spiders.

Insects display a staggering diversity of behaviors. Studying these systems provides insights into a wide range of ecological, evolutionary, and behavioral questions including the genetics of behavior, phenotypic plasticity, chemical communication, and the evolution of life-history traits. This accessible text offers a new approach that provides the reader with the necessary theoretical and conceptual foundations, at different hierarchical levels, to understand insect behavior. The book is divided into three main sections: mechanisms, ecological and evolutionary consequences, and applied issues. The final section places the preceding chapters within a framework of current threats to human survival - climate change, disease, and food security - before providing suggestions and insights as to how we can utilize an understanding of insect behavior to control and/or ameliorate them. Each chapter provides a concise, authoritative review of the conceptual, theoretical, and methodological foundations of each topic.

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.
