Describes the various stages of a monarch butterfly's life, from egg to pupa to caterpillar to butterfly, as well as its migration and dangers that it faces.

Every spring and summer, youth and adults alike enjoy sweet-smelling flowers and listening to the buzzing sound that comes from the rapidly beating wings of busy bees. Through a series of seven lessons and multiple experiential activities, youth will learn how critical bees are to our agricultural industry and native ecosystems. They will explore different types of bees, their structures, and functions, how they forage for food, pollinate plants, and the ways bees share information. Youth will study native bees and the honey bee and discover the significant role they play in the production of delicious and healthy food that humans have been eating for centuries; such as apples, blueberries, cherries, watermelons, and almonds. Through hands-on and engaging exploration of habitat differences and diversity, youth will understand what honey bees, native bees, and other pollinators need in order to thrive. From creating a pollinator garden to building mason bee homes, youth will realize the importance of pollinator stewardship and ways they can support strong and vibrant ecosystems for pollinators. The curriculum concludes with an overview of how people can help bees. Youth will learn how to provide nesting habitats, use best management practices in beekeeping and building native bee homes. To share and engage others in caring about bees, youth will create an awareness campaign.

While silk derived from silkworm has been of economic importance for centuries, more recently silkworm has been found to have utility in biomedicine. This has attracted attention for expressing eukaryotic recombinant proteins, which require post-translational modifications. In 1985 Dr. Susumu Maeda demonstrated that silkworm larvae could produce a functional human-interferon. Since then various techniques have been developed to express recombinant proteins in silkworm. With the development of the Bombyx mori nucleopolyhedrovirus (BmNPV) bacmid system, which is capable of replicating in both Escherichia coli and Bombyx mori derived cell lines or silkworm, silkworm larvae or pupae have been used for the expression system for recombinant protein production. This method has the advantage of a bacmid, in that it can be easily prepared for sufficient bacmid DNA for subsequent expression in silkworm. It is potentially a big breakthrough in production of recombinant eukaryotic proteins and viruses, which will be a powerful tool in a new proteome era. This volume contributes to the advancement of our knowledge in the subject, for example gene expression systems and silkworm research, and focuses on silkworm biofactories for the recombinant protein production and commercial applications of proteins.

The history of pathogens and vectors, unique symptoms of diseases and economic importance of important viral diseases have been dealt with in the introductory chapter of this book. While highlighting the role of arthropods, nematodes, and fungi; other agents of the spread of plant pathogens have also been included. Important aspects of insect vectors with direct bearing on transmission, i.e. vector identification, biology, feeding apparatus, and mechanism of spread including control of pathogens through vectors are covered comprehensively. As aphids and other hemipterous insects are major insect vectors, the book stresses on this order. There is a focus on the transmission of determinants under different categories of the transmission mechanism. The transmission determinant paradigm comprising coat protein and helper component has been expounded with recent cases. A brief description of new diseases at least one from each genus of plant viruses has been included in this compendium to elucidate the interaction of vector and virus. Phytoplasmal etiology of pathogens has been detailed separately on account of their importance. The transmission of plant viruses through insects with biting and chewing type of mouth parts has been discussed in detail as separate chapter. The latest research in the field of mites, nematodes, and fungi as vectors of plant viruses has been included. How the phytotoxemia is different from other crop disorders, has been critically explained with support from suitable and common examples of crop disorders. The book also highlights the effects of plant viruses on their vectors. An account of classification of plant viruses has also been given for better understanding of subject matter. Likewise, the information on the electron microscope along with its use has been included so as to define the procedure of examining sub-microscopic entities. The latest developments in the management of plant pathogens through vector management have been discussed with special reference to the use of biotechnology, crop protection, and plant resistance. The book will be of value to the teachers and to researchers. It will also be useful for extension workers in managing crop disorders. Students and researchers of entomology, plant pathology, plant protection and virology disciplines will obtain the latest in the field, through this book.

Bee hives. They might look at first glance like seething anarchy, but the bees know exactly what they are doing. With astounding skill, precise expertise and impressive teamwork they carry out their plans. The Honey Factory plunges the reader into the life of a colony of bees and takes them on a tour of their 'factory'. This is a world inhabited by headstrong individuals with clever methods and an amazing set of rules. Why aren't male bees allowed to stay in their colony just as it is getting cosy? What lies behind the sexual excesses of a young queen bee? And how do all the bees in a hive come to collective decisions? The Honey Factory answers these questions and more. Combining the most fascinating discoveries and greatest secrets in bee research, it ultimately shows readers why bees are so precious and why humans and bees cannot survive without each other.

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.
