Download or read book Factors Influencing Pesticide Resistance in Psylla Pyricola Foerster and Susceptibilty in Its Mirid Predator Deraeocoris Brevis Knight written by Hugo E. Baan (van de) and published by . This book was released on 1988 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Factors influencing pesticide susceptibility and resistance were studied in Psylla pyricola Foerster, and its mirid predator, Deraeocoris brevis Knight in the Rogue River Valley, Oregon. Factors studied were at the biochemical, life history, and population ecology levels. Studies on detoxification enzymes showed that glutathione S-transferase and cytochrome P-450 monooxygenase activities were ca. 1.6-fold higher in susceptible R. brevis than in susceptible pear psylla, however, esterase activity was ca. 5-fold lower. Esterase activity was ca. 18-fold higher in resistant pear psylla than in susceptible D. brevis, however, glutathione S-transferase and cytochrome P-450 monooxygenase activities were similar. Esterases seem to be a major factor conferring insecticide resistance in P. Pvricola. Although the detoxification capacities of P. pyricola and D. brevis were quite similar, pear psylla has developed resistance to many insecticides in the Rogue River Valley, whereas D. brevis has remained susceptible. Biochemical factors may be important in determining the potential of resistance development, however, they are less important in determining the rate at which resistance develops. Computer simulation studies showed that life history and ecological factors are probably of greater importance in determining the rate at which resistance develops in P. pvricola and D. brevis. High fecundity and low immigration of susceptible individuals into selected populations appear to be major factors contributing to rapid resistance development in pear psylla compared with D. brevis. Implications of this study for pesticide resistance management of pear psylla are discussed.

Download or read book Biological Control of Insect and Mite Pests in Iran written by Javad Karimi and published by Springer Nature. This book was released on 2021-04-28 with total page 621 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book provides a reference to biological control of arthropod pests in agriculture and of public health importance in Iran. A quick glance over the literature shows a long history of biocontrol attempts in the country. Some historically important events highlighting the interest of Iranian academic, research and extension fields to the natural enemies and their applied aspects are provided. Iran, with an exception of the former USSR, was a pioneer in both basic and applied biocontrol in West Asia. The book consists of four parts: three parts for predators, parasitoids and pathogens, and last part for other approaches and analyses of the current state of biological control in Iran. The book provides the most up-to-date information on pest control and related topics of entomology in Iran. The chapters are written by scholars from major Universities and research centers in Iran.

Download or read book Prospects for Biological Control of Plant Feeding Mites and Other Harmful Organisms written by Daniel Carrillo and published by Springer. This book was released on 2015-04-30 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: The history of biological control of harmful organisms by mites is marked by outstanding achievements with a few premiere natural enemies. Early works concentrated on the use of predatory mites for the control of synanthropic flies, More recently, the focus has been mostly on mites of the family Phytoseiidae for the control of plant feeding mites. This is an important family of acarine predators of plant pest mites, which are effectively used in agriculture worldwide. Besides the vast knowledge in several species in this family, there are as well many opportunities for biological control, represented in an array of organisms and through the improvement of management techniques, which are constantly explored by researchers worldwide. This has resulted in an increasing interest in predatory mite species within the families Stigmaeidae, Ascidae, Laelapidae, Rhodacaroidea, Macrochelidae, Erythraeidae and Cheyletidae, among others. This book will compile important developments with predatory mite species within these families, which are emerging as important tools for integrated pest management. New developments with predatory insects and pathogenic organisms attacking mites will also be a subject of this book. Finally, the potential and gaps in knowledge in biological control of acarine plant pests will be addressed.
Download or read book The Pear Genome written by Schuyler S. Korban and published by Springer. This book was released on 2019-07-03 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Addressing the pear genome, this book covers the current state of knowledge regarding genetic and genomic resources, breeding approaches and strategies, as well as cutting-edge content on how these tools and resources are being / soon will be utilized to pursue genetic improvement efforts that will combine fruit quality, high productivity, precocious fruit bearing, and long postharvest storage life, along with elevated levels of resistance to various major diseases and insect pests. Throughout, the book also explores potential opportunities and challenges in genomic analysis, sequence assembly, structural features, as well as functional studies that will assist in future genetic improvement efforts for pears. The pear (Pyrus), an important tree fruit crop, is grown worldwide, and has several economically relevant cultivars. In recent years, modern genetic and genomic tools have resulted in the development of a wide variety of valuable resources for the pear. In the past few years, completion of whole genome assemblies of ‘Dangshansuli’, an Asian pear, and ‘Bartlett’, a European pear, have paved the way for new discoveries regarding for example, the pear’s genomic structure, chromosome evolution, and patterns of genetic variation. This wealth of new resources will have a major impact on our knowledge of the pear genome; in turn, these resources and knowledge will have significant impacts on future genetic improvement efforts.
