Book Description
While working upon the problem of wax-scale manipulation during the summer of 1911 the writer became convinced that the so-called wax shears or pinchers of the worker honey bee have nothing whatever to do with the extraction of the wax scales from their pockets, but rather that they are organs used in loading the pollen from the pollen combs of the hind legs into the corbiculæ or pollen baskets. Further observations made at that time disclosed the exact method by which the hind legs are instrumental in the pollen-loading process and also the way in which the middle legs aid the hind legs in patting down the pollen masses. During the summer of 1912 additional information was secured, more particularly that relating to the manner in which pollen is collected upon the body and legs of the bee, how it is transferred to the hind legs, how it is moistened, and finally the method by which it is stored in the hive for future use. In the present paper a complete account will be given of the history of the pollen from the time it leaves the flower until it rests within the cells of the hive. The points of more particular interest in the description of pollen manipulation refer to (1) the movements concerned in gathering the pollen from the flowers upon the body and legs, (2) the method by which the baskets of the hind legs receive the loads which they carry to the hive, and (3) the manner in which the bee moistens pollen and renders it sufficiently cohesive for packing and transportation.

Book Description
The Behavior of the Honey Bee in Pollen Collection by Dana Brackenridge Casteel: In this insightful study, Dana Brackenridge Casteel examines the fascinating behavior of honey bees during pollen collection. Through meticulous observation and scientific analysis, Casteel sheds light on the intricate processes and instincts that drive these industrious insects in their vital role as pollinators. Key Aspects of the Book "The Behavior of the Honey Bee in Pollen Collection": Pollen Collection Techniques: Casteel explores the techniques and methods employed by honey bees in collecting pollen from various flowers and plants. Social Organization of Bees: The book delves into the hierarchical structure and cooperation among bees within a colony during pollen collection. Ecological Significance: Casteel highlights the critical ecological role of honey bees as pollinators and their impact on plant reproduction and biodiversity. Dana Brackenridge Casteel was a distinguished entomologist and researcher, known for her groundbreaking work on honey bee behavior and pollination. Her contributions to the field of entomology continue to inspire and inform scientific studies on the behavior of bees and their vital role in ecosystems.

Book Description
Floral Biology attempts to show how floral biologists conduct their experiments and what techniques they employ in floral biology. The techniques employed include those of physics, chemistry, physiology, psychology, genetics, and ecology, and so constitute a broad training in biology that may be useful and acceptable in other fields. Organized into 11 chapters, this book begins with a discussion on sex in flowers; the biology of the floral parts; agencies of pollination; and the pollen, nectar, and nectaries. Some chapters follow on pollination by birds, bats, and insects. The features of entomophilous flowers and isolating mechanisms in flowers are also described. Some hints for students, such as the tools required, how to make them, and a schedule of procedure for examining the floral biology of a species, are given in the last chapter. This book will attract workers, who, armed with the techniques and stimulated by the findings of the investigators, can introduce the floral biology to other fields.

Book Description
Intraspecific communication involves the activation of chemoreceptors and subsequent activation of different central areas that coordinate the responses of the entire organism—ranging from behavioral modification to modulation of hormones release. Animals emit intraspecific chemical signals, often referred to as pheromones, to advertise their presence to members of the same species and to regulate interactions aimed at establishing and regulating social and reproductive bonds. In the last two decades, scientists have developed a greater understanding of the neural processing of these chemical signals. Neurobiology of Chemical Communication explores the role of the chemical senses in mediating intraspecific communication. Providing an up-to-date outline of the most recent advances in the field, it presents data from laboratory and wild species, ranging from invertebrates to vertebrates, from insects to humans. The book examines the structure, anatomy, electrophysiology, and molecular biology of pheromones. It discusses how chemical signals work on different mammalian and non-mammalian species and includes chapters on insects, Drosophila, honey bees, amphibians, mice, tigers, and cattle. It also explores the controversial topic of human pheromones. An essential reference for students and researchers in the field of pheromones, this is also an ideal resource for those working on behavioral phenotyping of animal models and persons interested in the biology/ecology of wild and domestic species.

Book Description
Seeley, a world authority on honey bees, sheds light on why wild honey bees are still thriving while those living in managed colonies are in crisis. Drawing on the latest science as well as insights from his own pioneering fieldwork, he describes in extraordinary detail how honey bees live in nature and shows how this differs significantly from their lives under the management of beekeepers. Seeley presents an entirely new approach to beekeeping--Darwinian Beekeeping--which enables honey bees to use the toolkit of survival skills their species has acquired over the past thirty million years, and to evolve solutions to the new challenges they face today. He shows beekeepers how to use the principles of natural selection to guide their practices, and he offers a new vision of how beekeeping can better align with the natural habits of honey bees.

Book Description
This book describes and illustrates the results of more than fifteen years of elegant experimental studies conducted by the author to investigate how a colony of bees is organized to gather its resources. The results of his research--including studies of the shaking signal, tremble dance, and waggle dance--offer the clearest, most detailed picture available of how a highly integrated animal society works.

Book Description
Excerpt from The Behavior of the Honey Bee in Pollen Collecting Although, as above noted, some unbranched hairs are located upon the body of the bee, they occur in greatest numbers upon the more distal segments of the appendages. They are quite diverse in form, some being extremely long and slender, such as those which curve over the pollen baskets, others being stout and stifl', as those which form the collecting brushes and the pecten spines. The mouth parts Of the bee are also essential to the proper col lection of pollen. T h e mandibles are used to scrape over the anthers Of flowers, and considerable pollen adheres to them and is later removed. The same is true of the maxillae and tongue. From the mouth comes the fluid by which the pollen grains are moistened. The legs Of the worker bee are especially adapted for pollen gath ering. Each leg bears a collecting brush, composed Of stiff, un branched hairs set closely together. These brushes are located upon the first or most proximal tarsal segment of the legs, known techni cally as the palmae of the forelegs and as the plantae of the middle and hind pair. The brush of the foreleg is elongated and of Slight width (fig. That of the middle leg broad and flat (fig. While the brush upon the planta of the hind leg is the broadest of all, and is also the most highly Specialized. In addition to these well-marked brushes, the distal ends Of the tibiae of the fore and middle legs bear many stiff hairs, which function as pollen collectors, and the distal tarsal joints Of all legs bear similar structures.
