The Ecology of insect populations in theory and practice. by Clark, L. R.(CARDINAL)322937;
Includes bibliographical references (pages 209-224)."This book seeks to fulfill the need for a concise and inexpensive text on population ecology. It presents general principles derived from demographic studies of insects in various parts, of the world, and shows how those principles bear upon the practice of ecology both in research and in the management of biological resources. The book is aimed at a wide audience including students and teachers of ecology, and economic entomologists. After reviewing the development of ecological thought since Darwin, the authors discuss the views advanced by modern theorists to explain how animal numbers are determined, and describe a comprehensive and functional way of envisaging the dynamics of insect populations, suited to the problems confronting most ecologists today and to modern methods of work. The authors show how their generalized model can serve for the derivation of explanatory synthesis of population dynamics in a number of cases ranging from investigations pursued under laboratory conditions to large-scale field studies. Recognized approaches to the study of numerical determination in insect populations are presented synoptically according to the characteristics of the information sought. In addition, the authors present a comprehensive discussion of pest control, in which they test the practical efficacy of their views and analyze the relation of demographic ecology to the management of pests. The book is concluded by outlining the ecological research needed to advance our understanding of insect behavior." BOOK JACKET.

The insect crisis : the fall of the tiny empires that run the world / by Milman, Oliver,author.;
Includes bibliographical references (pages 223-241) and index.Prologue -- An intricate dance -- Winners and losers -- "Zero insect days" -- The peak of the pesticide -- In the teeth of the climate emergency -- The labor of honeybees -- A monarch's journey -- The inaction plan -- A human emergency."A devastating exploration of how the collapse in insect populations around the world threatens everything from wild birds to the food on our plate. From the ants scurrying under leaf litter to the bees able to fly higher than Mount Kilimanjaro, insects are seemingly everywhere. Three out of four of the planet's known species are insects, but a torrent of recent evidence suggests this kaleidoscopic group of creatures is suffering the greatest existential crisis in its remarkable 400-million-year history. Oliver Milman delves into why insect numbers are plummeting and outlines the dire consequences of losing the tiny empires that hold life aloft on Earth. Along the way, readers encounter a researcher who collects insect guts from the windshields of cars, the bees sent on long-haul truck journeys to prop up our food supply, and a desperate attempt to move trees up mountains to save an iconic butterfly. The mounting losses threaten to unpick the web of life we rely upon. Illuminating and inspiring, The Insect Crisis is a wake-up call for all of us"--

Buzzkill : a wild wander through the weird and threatened world of bugs / by Maloney, Brenna,author.(CARDINAL)499147; Mottram, Dave,illustrator.(CARDINAL)350792;
Includes bibliographical references and index.Scope and scale -- Feeding the world -- Insects as food -- Cleanup on aisle four -- And everything else -- How insects suck -- E is for extinction -- How it matters -- Reproduction and resilience -- Doing our part."The praying mantis is the only animal on Earth with one ear--and it's in the middle of its chest. Aphids are born pregnant. Moths can't fly during an earthquake. If you didn't know these things, you soon will. Packed full of jaw-dropping facts, Buzzkill presents the big picture on bugs. You might think ew, gross. Insects are icky. Or scary. Or dangerous. They can be. But there's so much more you need to know. Insects play a critical role on our planet, from sustenance to pollination to medicines and more. Brenna Maloney tackles both the wacky and weird, as well as threats to insects and their habitats, their possible extinction, and ways that everyday people, like you, can prevent their decline." -- Amazon.com.Grades 7-9Ages 10-14930L

Extinct & endangered : insects in peril / by Biss, Levon,photographer.(CARDINAL)836915; Biss, Levon,photographer.(CARDINAL)836915; Grimaldi, David A.,writer of foreword.(CARDINAL)330752; American Museum of Natural History.(CARDINAL)138269;
"Extraordinary images by master macro photographer Levon Biss capture a vanishing world of insects from the collections of the American Museum of Natural History in New York. This joint project of photographer Levon Biss and the American Museum of NaturalHistory contains indelible images of 40 extinct or endangered species in the museum's collection, selected from its vast holdings by a team of scientists. All were sent to Biss's studio, where he created commanding portraits that can be enlarged 300-times lifesize to reveal vivid full-page details of form and color -- a world invisible to our naked eyes" --
