DOWNLOAD EBOOKInsects as a group occupy a middle ground in the biosphere between bacteria and viruses at one extreme, amphibians and mammals at the other. The size and general nature of insects present special problems to the student of entomology. For example, many commercially available instruments are geared to measure in grams, while the forces commonly encountered in studying insects are in the milligram range. Therefore, techniques developed in the study of insects or in those fields concerned with the control of insect pests are often unique. Methods for measuring things are common to all sciences. Advances sometimes depend more on how something was done than on what was measured; indeed a given field often progresses from one technique to another as new methods are discovered, developed, and modified. Just as often, some of these techniques find their way into the classroom when the problems involved have been suffi ciently ironed out to permit students to master the manipulations in a few lab oratory periods. Many specialized techniques are confined to one specific research laboratory. Although methods may be considered commonplace where they are used, in another context even the simplest procedures may save considerable time. It is the purpose of this series (1) to report new developments in methodology, (2) to reveal sources of groups who have dealt with and solved particular entomo logical problems, and (3) to describe experiments which may be applicable for use in biology laboratory co~rses.

DOWNLOAD EBOOKThe Decision Between Us combines an inventive reading of Jean-Luc Nancy with queer theoretical concerns to argue that while scenes of intimacy are spaces of sharing, they are also spaces of separation. John Paul Ricco shows that this tension informs our efforts to coexist ethically and politically, an experience of sharing and separation that informs any decision. Using this incongruous relation of intimate separation, Ricco goes on to propose that “decision” is as much an aesthetic as it is an ethical construct, and one that is always defined in terms of our relations to loss, absence, departure, and death. Laying out this theory of “unbecoming community” in modern and contemporary art, literature, and philosophy, and calling our attention to such things as blank sheets of paper, images of unmade beds, and the spaces around bodies, The Decision Between Us opens in 1953, when Robert Rauschenberg famously erased a drawing by Willem de Kooning, and Roland Barthes published Writing Degree Zero, then moves to 1980 and the “neutral mourning” of Barthes’ Camera Lucida, and ends in the early 1990s with installations by Felix Gonzalez-Torres. Offering surprising new considerations of these and other seminal works of art and theory by Jean Genet, Marguerite Duras, and Catherine Breillat, The Decision Between Us is a highly original and unusually imaginative exploration of the spaces between us, arousing and evoking an infinite and profound sense of sharing in scenes of passionate, erotic pleasure as well as deep loss and mourning.

DOWNLOAD EBOOKCommon among moths is a mate-finding system in which females emit a pheromone that induces males to fly upwind along the pheromone plume. Since the chemical pheromone of the domesticated silk moth was identified in 1959, a steady increase in the number of moth species whose pheromone attractants have been identified now results in a rich base for review and synthesis. Pheromone Communication in Moths summarizes moth pheromone biology, covering the chemical structures used by the various lineages, signal production and perception, the genetic control of moth pheromone traits, interactions of pheromones with host-plant volatiles, pheromone dispersal and orientation, male pheromones and courtship, and the evolutionary forces that have likely shaped pheromone signals and their role in sexual selection. Also included are chapters on practical applications in the control and monitoring of pest species as well as case studies that address pheromone systems in a number of species and groups of closely allied species. Pheromone Communication in Moths is an invaluable resource for entomologists, chemical ecologists, pest-management scientists, and professionals who study pheromone communication and pest management.

DOWNLOAD EBOOKInsects are seldom mentioned in discussions surrounding human history, yet they have dramatically impacted today's societies. This book places them front and center, offering a multidisciplinary view of their significance. Diseases vectored by insects have killed more people than all weapons of war. Fleas are common pests, but some can transmit illnesses such as the bubonic plague. In fact, three pandemics can be traced back to them. Epidemics of typhus have been caused by lice. Conversely, humans have also benefitted from insects for millennia. Silk comes from silkworms and honey comes from bees. Despite the undeniably powerful effects of insects on humans, their stories are typically left out of our history books. In The Silken Thread, entomologists Robert. N. Wiedenmann and J. Ray Fisher link the history of insects to the history of empires, cultural exchanges, and warfare. The book narrows its focus to just five insects: a moth, a flea, a louse, a mosquito, and a bee. The authors explore the impact of these insects throughout time and the common threads connecting them. Using biology to complement history, they showcase these small creatures in a whole new light. On every page, the authors thoughtfully analyze the links between history and entomology. The book begins with silkworms, which have been farmed for centuries. It then moves to fleas and their involvement in the spread of the plague before introducing the role lice played in the Black Death, wars, and immigration. The following section concerns yellow fever mosquitos, emphasizing the effects of yellow fever in the Americas and the connection to sugar and slavery. After discussing the importance of western honey bees, the authors tie these five insects together in an exciting closing chapter.
