Available in PDF, EPUB and Kindle. Book excerpt: Planthoppers include some of the most devastating pests of major agricultural crops throughout the world. One species, the rice brown planthopper, is among the most economically important pests in Asia. In past decades, government policies encouraged the control of rice planthoppers with synthetic pesticides, a tactic which promoted insecticide resistance and often led to the pesticide-induced resurgence of pest populations. To deter planthopper outbreaks, a more ecologically sound management strategy is being implemented, one based on a thorough investigation of population dynamics, natural enemies, and the genetics of host plant and insecticide adaptation. In the natural habitats of North America and Europe, scientists have also used planthoppers as model organisms to test ecological and evolutionary theory. The consequence of these diverse studies is an extremely scattered literature on planthoppers that has never been synthesized from an ecological perspective. This volume summarizes what is known about planthopper ecology and biological control. It takes a theoretical approach yet is deeply concerned with the application of theory to the practical problems of pest management.

This book was released on 2011-09-24 with total page 554 pages. Available in PDF, EPUB and Kindle. Book excerpt: This issue of ZooKeys celebrates the 75th birthday of Alexandr P. Rasnitsyn, a pioneer in the palaeontology and phylogeny of Hymenoptera, as well as a leader generally in insect systematics and evolution. Born in Moscow, Russia, on 24 September 1936, he developed his passion for Hymenoptera at an early age. After completing his degrees in 1960 he joined the Arthropoda Laboratory in the Paleontological Institute of the USSR (now Russian) Academy of Sciences, Moscow, and worked his way from Technician to the Head of the laboratory, in this capacityÿ leading the most productive group of paleoentomologists for 28 years. He has co-authored and edited several keystone books on insect paleontology and evolution, including History of Insects (2002), the first large-scale work of its kind in English. Rasnitsyn served as the first President of the International Palaeoentomological Society, and was bestowed Honorary Membership by the Russian Entomological Society and in 2008 with the Distinguished Research Medal of the International Society of Hymenopterists. Herein colleagues from around the world have presented original contributions to the systematics of diverse insect orders, living and fossil, as a tribute to this pioneer of Hymenoptera and paleoentomological research. Numerous new taxa are described and their phylogenetic implications explored. A biographical sketch and a list of Rasnitsyn?s more than 360 scientific publications (spanning 52 years) are provided.

Download or read book Parasitoid Wasps of South East Asia written by Buntika A. Butcher and published by CABI. This book was released on 2023-12-22 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: Parasitoid wasps are cosmopolitan, numerous and enormously diverse with probably one million or more species worldwide, most of which occur in the moist tropics. Their ecological importance is enormous although perhaps most evident in their major roles in the control of insect pest populations. In natural ecosystems they are integral in regulating populations of a vast number of insects, and therefore are key players in terrestrial food webs. Knowledge of their biology is still very poor because the current state of taxonomy is still in its infancy in most parts of the world.In this book, we provide an overview of the more than 30 families of parasitoid wasps that occur in the 11 countries in South East Asia. Particular emphasis is given to those most commonly encountered and reared, as well as to those used in biological control programmes. Outlines of the morphology, biology, ecology and behaviour of each family, as well as of various important subfamilies are presented. The current state of taxonomy in the region is summarised. Other chapters cover basic biology, behaviour, morphological terminology, phylogeny and methods of specimen collecting, preparation and rearing with particular relevance to the tropics. Modern molecular approaches to speeding taxonomic description of hyperdiverse taxa are considered in depth. All groups are illustrated with colour photographs. This book will be of value to professional entomologists, academics, entomology students and the growing body of amateur entomologists and insect photographers.

Download or read book Sustainable Management of Phytoplasma Diseases in Crops Grown in the Tropical Belt written by Chrystel Y. Olivier and published by Springer Nature. This book was released on 2020-02-05 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: With 160+ countries and islands, the tropical belt is the geographical region centered on the equator and limited by the tropics of Cancer and Capricorn. Tropical agricultural production is mostly for local consumption but cash crops are also present. Tropical agriculture is characterized by a significant lack of capital in research and agricultural systems and by a high prevalence of insect pests and diseases. Phytoplasma diseases are associated by bacteria-like pathogens living in plant sap and spread by sap-feeding insects. They are emerging diseases and are difficult to control, mostly because their epidemiology is not known. This book will focus on detection and prevention of phytoplasma diseases in field and horticultural crops grown in the tropical belt. The book will review current prevention methods used in small and large-scale farms, and present research results aiming at developing sustainable management of phytoplasma diseases in the tropics.
