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
Over the years farmers have over relied on chemical pesticides as the main strategy for controlling pests in French beans. Consequently, there has been a pest resurgence, environmental damage, pest resistance as well as lethal effects on non target beneficial organisms. A shift to the more environment friendly biological control of pests is therefore prudent. This book explores and provides an insight on the potential of Entomopathogenic nematodes, Heterorhabditis bacteriophora, and Steinernema karii, as a biological control agent against flower thrips, Frankliniella occidentalis and Megalurothrips sjostedti in French beans.The book will be found especially useful to all proponents of biological pest control and more so to researchers and other professionals in search of biological pest control. All persons interested in exploiting the potential of EPNs as a biological Agent will also find the book useful

Book Description
The present research aimed to study efficiency of 41 isolates of entomopathogenic fungi, belonging to 25 species from 11 genera isolated from different hosts in Thailand, as biological control agents against Frankliniella occidentalis (PERGANDE) and Thrips tabaci LINDEMAN (Thys., Thripidae). Firstly, the efficiency isolates was screened in the laboratory for the following characteristics: pathogenicity, virulence degree and effectiveness. In further experiments, the isolates that displayed highly efficient were subjected to studies biological and ecological characteristics, mode of infection, their efficiency under abiotic and biotic factors as well as side effects on non-target arthropods. Finally, persistence on different host plants and efficiency for controlling thrips under greenhouse conditions were investigated. In the laboratory, the results showed that 37 isolates for F. occidentalis and 36 isolates for T. tabaci were found to be pathogenic. The 16 isolates were highly pathogenic. Fungi isolates varied significantly in term of virulence. Five isolates were superior to all other isolates according to the virulence degree. The efficiency against all stages of both thrips species showed that the susceptibility decreased from larvae over pupae to adults. Beauveria bassiana Bb.5335 and Metarhizium anisopliae Ma.7965 displayed the highest efficacy throughout the following series of screenings and were used for further experimentation. Biological characteristics of B. bassiana and M. anisopliae were dependent on environmental factors but they did not greatly affect. The process involving pathogenicity on thrips began from 12 h and was completed within 72 h after inoculation. However, temperature and life stage of thrips were found to have effects on the development of pathogenicity process. The efficacy of the two fungi was higher at 25 and 30°C than at 18 and 35°C. Those increased with increasing relative humidity and varied according to the host plant whether on crop or ornamental plants. Both thrips species reared on cucumber were highly susceptible to fungal infection but significantly less susceptible when reared on saintpaulia. B. bassiana and M. anisopliae had low side effects on non-target beneficial arthropods.

Book Description
The International Centre for Advanced Mediterranean Agronomic Studies (CIHEAM), established in 1962, is an intergovernmental organization of 13 countries: Albania, Algeria, Egypt, France, Greece, Italy, Lebanon, Malta, Morocco, Portugal, Spain, Tunisia and Turkey. Four institutes (Bari, Italy; Chania, Greece; Montpellier, France; and Zaragoza, Spain) provide postgraduate education at the Master of Science level. CIHEAM promotes research networks on Mediterranean agricultural priorities, supports the organization of specialized education in member countries, holds seminars and workshops bringing together technologists and scientists involved in Mediterranean agriculture and regularly produces diverse publications including the series Options Méditerranéennes. Through these activities, CIHEAM promotes North/South dialogue and international co-operation for agricultural development in the Mediterranean region. Over the past decade, the Mediterranean Agronomic Institute of Zaragoza has developed a number of training and research-supporting activities in the field of agroecology and sustainability of agricultural production systems. Some of these activities have been concerned with the rational use of pesticides and more particularly with the implementation of integrated control systems in order to gain in efficacy and decrease both the environmental impact and the negative repercussions for the commercialization of agricultural products.
