Book Description
The 9th International Symposium on Insect-Plant Relationships (SIP-9) was once more, following the tradition established in 1958, a forum for investigators in both basic and applied entomology interested in the important and fascinating field of interactions between plants and insects. We were pleased and honoured to organise this symposium, which took place June 24--30, 1995 in Gwatt on the shores of the Lake of Thun in Switzerland. 168 participants from 26 countries from all over the world actively took part in the symposium by contributing 12 key-note lectures and a total of 141 oral presentations and posters. The favourable response and the lively interaction of the participants in all symposium activities is the clearest indication of the success of SIP-9. The organisers appreciated the enthusiasm and the willingness to collaborate shown by all participants. The following volume contains written contributions (72) of only half of all presentations. This is due to the fact that we decided to produce not only an account of the proceedings but also to publish all contributions as a special volume of the journal Entomologia Experimentalis et Applicata. This procedure was last adopted in 1978 for SIP-4, organised by Reginald F. Chapman and Elizabeth A. Bernays, and ensures a wide distribution of the papers within the scientific community and easy access through libraries. Inevitably we had to employ the same review procedure as applicable for the manuscripts regularly submitted to Entomologia.

Book Description
Thrips (fhysanoptera) are very small insects, widespread throughout the world with a preponderance of tropical species, many temperate ones, and even a few living in arctic regions. Of the approximately 5,000 species so far identified, only a few hundred are crop pests, causing serious damage or transmitting diseases to growing crops and harvestable produce in most countries. Their fringed wings confer a natural ability to disperse widely, blown by the wind. Their minute size and cryptic behavior make them difficult to detect either in the field or in fresh vegetation transported during international trade of vegetables, fruit and ornamental flowers. Many species have now spread from their original natural habitats and hosts to favorable new environments where they often reproduce rapidly to develop intense damaging infestations that are costly to control. Over the past decade there have been several spectacular examples of this. The western flower thrips has expanded its range from the North American continent to Europe, Australia and South Africa. Thrips palmi has spread from its presumed origin, the island of Sumatra, to the coast of Florida, and threatens to extend its distribution throughout North and South America. Pear thrips, a known orchard pest of Europe and the western United States and Canada has recently become a major defoliator of hardwood trees in Vermont and the neighboring states. Local outbreaks of other species are also becoming problems in field and glasshouse crops as the effectiveness of insecticides against them decline.

Book Description
It appears that a comprehensive and up-to-date book on the impact of virus diseases on the major crops in developing countries is now much needed, especially as there have been rapid advances in the biological and molecular characterization and detection of the pathogens and possible approaches for their control. On the other hand, the economic losses caused by many of these diseases are tremendous and much of the accumulated knowledge to diminish the crop losses has not filtered through, or cannot be applied. This book is focused on the important crops. Each chapter on a specific crop will include inter alia, geographical distribution, the viruses - symptoms, damage, detection - a brief description of the viruses concerned, and present and future ways for their control. Experts from India, Nigeria, UK, USA, France, Germany, Peru, Japan, Australia, Netherlands, Venezuela, Kazakhstan and Israel (many of them from the International Research Institutions) have contributed chapters to this book.

Book Description
In this book, 'state of art' situation in patterns of behaviour is presented by the authors, each with expertise in respective fields on diverse aspects such as pollination, predation and parasitism, forest and agricultural pests, besides the dynamics of aquatic insects in general and dragonflies in particular, in addition to insect vectors of diseases. The need for an appreciation of the differentiation processes controlling growth and development of plant galls has been adequately emphasised, these galls representing highly regulated growth manifestations of plants, ensuring nutrition and shelter for the insects concerned. Behavioural shifts of insects due to current climatic changes and their implications in insect conservation and control are also highlighted. This book will be relevant to the undergraduate and particularly graduate students taking courses in insect ecology and evolution, conservation biology and environmental management as well as to committed researchers in these fields in addition to conservation practitioners eager to have a comprehensive background of the multifaceted aspects of insect behavioural dynamics.

Book Description
This edited volume focuses on parasite-host relationships and the behavioral changes parasites may trigger in their hosts. Parasites have developed strategies which enhance their chances to find a host to survive inside its body and to become most easily transmitted to one another. Many of these parasites influence the host’s behavior by various mechanisms, so that the rate of their transmissions to further hosts becomes considerably enhanced in comparison to that of non-influenced specimens of the same host species. A broad number of recent studies elucidate more and more examples in an extreme spectrum of host-parasite relationships, where successful transmission and /or survival of a parasite inside a host is based on parasite-derived behavioral manipulations of the hosts. In the literature, an increasing numbers of papers appear which prove that these behavioral alterations are based on complicated psychoimmunologic, neuropharmacologic and genomically steered mechanisms. Researchers working in parasitology or behavioral sciences will find this work thought-provoking, instructive and informative.

Book Description
"The objectives of this thesis were to review the existing literature on predatory soil mites and alternative food sources in biocontrol systems, identify a suitable natural predator for controlling invasive thrips species Echinothrips americanus and Thrips parvispinus, and investigate the role of increased soil biodiversity in shaping plant phenology traits.The thesis starts with an overview of below-ground biocontrol systems using predatory soil mites to manage pests in the soil with the aim to consolidate existing studies, emphasizing the potential of these natural enemies which have had limited research in this area. Since the focus of the thesis is biological control, I next focused on the role of alternative food for natural enemies and its effects on predator and pest populations. Using a meta-analysis approach, I revealed that introducing natural enemies before pests and providing alternative food can enhance long-term biocontrol effectiveness.Moving towards the experimental chapters of the thesis, I started by testing predatory mites to control thrips on various plants and showed promising results for controlling T. parvispinus with certain predatory soil mites. Since biocontrol of E. americanus was not successful, I explored thrips' antipredator behaviours, which might hinder predator success. Echinothrips americanus displayed these behaviours most frequently of all the thrips investigated, making it challenging for predatory mites to prey on them. Lastly, I investigated the effects of increased soil biodiversity on plant performance, showing improved plant performance under suboptimal fertilization conditions when adding the predatory soil mite S. scimitus and its associated soil biota."--
