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.

A number of species of Thysanoptera (thrips) are increasingly important crop pests in many parts of the world, as well as in some cases being vectors of plant disease. Communicating the known information about a species of organism is dependent on our ability to recognize or identify it accurately. This book is a completely revised and rewritten edition of the standard, widely used manual on these minute flying insects written by J.M. Palmer, L.A. Mound and G.J. du Heaume and published in 1989 as CIE Guides to Insects of Importance to Man 2. Thysanoptera, which provides a practical identification guide on a worldwide scale. The previous version posed problems for students in terms of fluency in English & knowledge of dichotomous keys. However, this thoroughly updated edition incorporates a new set of pictorial keys, which have been developed and used very successfully for training courses at the International Institute of Entomology and which will greatly enhance the ability of the non-specialist to identify thrips to species. Individuals of these insects can usually be identified only by examination under a microscope, often at high power. Within each species, individuals can vary in size, colour and shape and their appearance can be altered by techniques used in preparation. This booklet describes techniques used in the preparation of thrip specimens onto slides for identification and the means of identifying slide-mounted specimens most commonly encountered. It also introduces students to the biological diversity that is found amongst the Thysanoptera, their economic importance in terms of both damaging and beneficial effects, new identification techniques, additional information and taxa, glossary of technical terms, notes on each genus (described alphabetically within their families and subfamilies). Supplementary keys to species are also given within four genera that include several pest species (Caliothrips, Frankliniella, Scirtothrips and Thrips) along with new distribution records which have occurred since the publication of the first edition. It is an essential tool for applied entomologists and crop protection specialists involved in the control of crop pest thrips, and thrip taxonomists.

This is a textbook providing basic data about the crop pests and the damage they inflict throughout the tropics and sub-tropics. Each major pest is illustrated by either a line drawing or a photograph, and sometimes the damage can also be seen. A world distribution map is provided for each species. Control measures tend to be general rather than very specific. Most of the pests are insects and mites, but some nematodes, molluscs, birds and mammals are included.

This comprehensive handbook on economic entomology for Australian field crops and pastures is the first of its kind. It encompasses pests and beneficial insects as well as allied forms of importance in Australian agriculture. Organised by commodities – such as cereals, sugar and tropical pasture legumes – it examines all the pest species for a particular commodity across Australia. Identification, distribution, damage, host range, biology, risk period and monitoring techniques are described for each entry, accompanied by useful illustrations. The book also describes introduced biological control agents that effectively control crop pests. Pests of Field Crops and Pastures will be a useful tool in crop management for progressive farmers, agronomists, agricultural consultants and academics alike.

The main purpose of this book is to complement the hitherto largely descriptive works on the order Thysanoptera, by presenting thrips as living animals, stressing the behaviour of individuals and populations, their varied and complex relationships with plants, other animals and the physical components of their abundance in undisturbed and in cultivated habitats, and in cultivated economic importance as pests and beneficia. A considerable literature on thrips has accumulated over the last one hundred years. Unifortunately much of this information is fragmentary, scattered through obscure pamphlets, journales and accsesible only with difficulty.

Early season thrips damage to cotton can reduce yield and kill plant terminals. Control measures and the compounds used to control thrips vary widely. Thrips species, such as onion thrips, Thrips tabaci Lindman and western flower thrips, Frankliniella occidentalis (Pergande), are major contributors to the agricultural crop pest spectrum on numerous crops. The persistence of these two species as crop pests has led to the delineation of species-specific tactics for insecticidal control measures. The primary objective of this research was to characterize and compare attributes of five insecticides in different classes: anthranilic diamide (352-DPX), microcyclic lactone (spinosad, Tracer® 4 SC), neonicotinoid (thiomethoxam, Cruiser® 40 WG), carbamate (oxamyl, Vydate® L) and organophosphate (acephate, Orthene® 90 S) with thrips activity. Insecticidal potency, feeding/oviposition preference, reproductive effects and feeding damage were studied on T. tabaci and F. occidentalis . Adult potency data (LC50 or dose response mortality of each compound) showed that all compounds were more potent on T. tabaci than F. occidentalis . 352-DPX was 3823X less potent on F. occidentalis, followed by Orthene (411X), Vydate L (11X), and Tracer and Centric both with 6X lower potency on F. occidentalis . Results from the feeding and oviposition preference and reproductive effects bioassay indicated that adult T. tabaci and F. occidentalis tended to be equally distributed between treated and untreated leaves. Some exceptions are discussed where significantly more adults thrips were found on the untreated than treated leaves. The feeding and oviposition preference results indicate that in spite of the significantly lower potency on F. occidentalis, leaves treated with all compounds were less preferred over untreated leaves for feeding and oviposition, resulting in significantly lower larvae and feeding damage. Interestingly, only 352-DPX, Tracer and Vydate had this same effect on T. tabaci . Additional results indicate that sublethal concentrations (e.g. LC10 and LC50) had an effect on feeding and progeny reduction. Finally, treated leaves resulted in lower percent plant damage, caused feeding cessation, and subsequently influenced larval populations. An improved population assessment for thrips management and plant protection was developed based on these findings.
