Genetics, Evolution, and Biological Control

Genetics, Evolution, and Biological Control PDF Author: Lester E. Ehler
Publisher: CABI
ISBN: 9780851998671
Category : Biological pest control agents
Languages : en
Pages : 280

Book Description
Annotation. This book has been developed from the keynote addresses delivered at the third IOBC International Symposium (co-organized with CILBA) that was held in Montpellier in October 2002, to address recent developments in genetics and evolutionary biology as applied to biological control. Chapters are organized around the following themes: Genetic structure of pest and natural enemy populations Molecular diagnostic tools in biological control Tracing the origin of pests and natural enemies Predicting evolutionary change in pests and natural enemies Compatibility of transgenic crops and natural enemies Genetic manipulation of natural enemies. The authors identify new issues for each of the major approaches in applied biological control. These include the (1) use of molecular genetics to trace the origin of target pests in classical biological control, (2) potential of mass-reared, transgenic agents in augmentative biological control, and (3) compatibility of transgenic crops and natural enemies in conservational biological control.

Pesticide Chemistry

Pesticide Chemistry PDF Author: G. Matolcsy
Publisher: Elsevier
ISBN: 0080874916
Category : Technology & Engineering
Languages : en
Pages : 809

Book Description
This book provides an overview of the major chemical aspects of pesticides giving detailed descriptions of the various groups of pesticides in current use - insecticides, acaricides, nematocides, rodenticides, fungicides and herbicides. The organic syntheses are discussed in detail, as are the biochemical aspects of the effectiveness and mechanisms of action of these chemical agents. The ecological aspects of the use of pesticides - nowadays an important consideration - are also discussed.The main trends of development in the field are also dealt with, e.g. the development of insecticides which present less of a threat to human beings and animals than the ones presently used, whose point of attack is the nervous system. Research is now concentrated on developing chemical compounds which affect the biochemistry or the special behavioural features of insects, instead of acting upon their nervous system. Newly discovered chemicals with selective action which are still in the developmental and experimentational stages are also described.Because of its comprehensive character, the book will be a useful source of information to those engaged in practical work in this field, as well as to researchers in the agricultural sciences.

Insecticide Biochemistry and Physiology

Insecticide Biochemistry and Physiology PDF Author: Wilkinson
Publisher: Springer Science & Business Media
ISBN: 1489922121
Category : Medical
Languages : en
Pages : 777

Book Description
Only four short decades ago, the control of insect pests by means of chemicals was in its early infancy. The pioneers in the area consisted largely of a group of dedicated applied entomologists working to the best of their abilities with a very limited arsenal of chemicals that included inorganics (arsenicals, fluorides, etc.), some botanicals (nicotine), and a few synthetic organics (dinitro-o-cresol, organothiocyanates). Much of the early research was devoted to solving practical problems associated with the formulation and application of the few existing materials, and although the discovery of new types of insecticidal chemicals was undoubtedly a pipe dream in the minds of some, little or no basic research effort was expended in this direction. The discovery of the insecticidal properties of DDT by Paul Miiller in 1939 has to be viewed as the event which marked the birth of modern insecticide chemistry and which has served as the cornerstone for its subse quent developement. DDT clearly demonstrated for the first time the dramatic potential of synthetic organic chemicals for insect control and provided the initial stimulus which has caused insecticide chemistry to become a field not only of immense agricultural and public health importance but also one that has had remarkable and unforseeable repercussions in broad areas of the physical, biological, and social sciences. Indeed, there can be few other synthetic chemicals which will be judged in history to have had such a broad and telling impact on mankind as has DDT.

Chalcidoidea of Iran

Chalcidoidea of Iran PDF Author: Hassan Ghahari
Publisher: CABI
ISBN: 1789248469
Category : Science
Languages : en
Pages : 446

Book Description
The superfamily Chalcidoidea (Insecta, Hymenoptera) contains in excess of 26,000 described species worldwide, but with an estimated total diversity of more than 500,000 species the vast majority of species have yet to be discovered and described. Most chalcidoid species are parasitoids of hosts in at least 12 different insect orders, attacking the egg, larval or pupal stages, though phytophagy and other life cycles and hosts are known. Iran is the 18th largest country in the world and has a rich and diverse insect fauna, including Chalcidoidea. It is extremely interesting from a biogeographic point of view, and a paradise for an entomologist. This book summarizes the results of all prior research concerning species diversity of Iranian Chalcidoidea, including host records and distribution records by province in Iran as well as world distribution by country for 1,351 species of Chalcidoidea recorded from Iran through the end of 2019.
