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
[Truncated abstract] Integrated pest management (IPM) relies on the use of multiple tactics to reduce pest numbers below an economic threshold. One of the challenges for the implementation of IPM is using both insecticides and biological control. This is particularly difficult in horticultural crops where very little damage can be tolerated. Western flower thrips, Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae) is a worldwide pest of economic importance associated with cultivated crops, ornamentals and weeds. It is considered a major pest of strawberry, Fragaria x ananassa Duchesne (Rosaceae), and can be responsible for substantial yield loss. Insecticides are the main method of control for F. occidentalis in strawberry and other crops. Due to the rapid development of insecticide resistance and the limitations of existing biological control in Australia, there is a need to incorporate insecticides, natural enemies, and resistant host plants to keep the population below an economic threshold. This project sought to (i) evaluate commercial strawberry varieties for feeding and oviposition preferences of F. occidentalis, (ii) assess the compatibility of natural enemies with an insecticide currently used for F. occidentalis control in IPM programs, (iii) assess the effectiveness of the release of multiple species of natural enemies, (iv) determine the residual threshold of an insecticide which controls F. occidentalis effectively whilst having a reduced effect on natural enemies, and (v) assess the compatibility of natural enemies with an increased rate of an insecticide to manage an insecticide-resistant strain. Frankliniella occidentalis showed a distinctive olfactory preference in a choice trial evaluating the feeding preference of F. occidentalis to strawberry cultivars (Camarosa, Albion and Camino Real). Frankliniella occidentalis was attracted most to Camarosa for both feeding and oviposition, followed by Albion and Camino Real. Frankliniella occidentalis also preferred to feed on fresh leaves to those that had been fed upon by a conspecific. Of the three varieties tested, Camino Real was the least preferred cultivar for oviposition. The development period of F. occidentalis (from eggs to adult emergence) was shortest in Camarosa and longest in Camino Real. Overall, of the three varieties tested, Camarosa appeared the most favourable for F. iii occidentalis feeding, oviposition and population growth, and the other cultivars might be a better choice for growers seeking to reduce F. occidentalis populations...

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.
