The document provides an up-to-date recommendations made to WHO by the experts of WHO consultations on discriminating concentrations of insecticides for monitoring resistance in adult mosquito vectors. It is an outcome of a WHO multi-centre study (2017–2021) performed by 23 laboratories in different regions and the WHO expert consultations that made recommendations to WHO on insecticide discriminating concentrations for monitoring resistance in Anopheles and Aedes spp. The document describes a new WHO bottle bioassay method for testing susceptibility of mosquitoes to insecticides that are not suitable for impregnation on filter papers and makes recommendations for future scientific research on development of methods and procedures for testing resistance against insecticides with new, novel or distinct modes of action. Making use of the recommendations made to WHO by the experts, WHO will soon update current WHO test methods and procedures and publish standard operating procedures for testing insecticide resistance in mosquitoes, which in turn will be useful to the national vector-borne disease control programmes, in particular the entomological surveillance units, and the research community for monitoring insecticide resistance in field populations of mosquito vectors of disease. The document will also be useful to academia, the pesticide regulatory agencies and the pesticide industry for further innovation in this area and to address the research questions.

Bruce E. Tabashnik and Richard T. Roush Pesticide resistance is an increasingly urgent worldwide problem. Resistance to one or more pesticides has been documented in more than 440 species of insects and mites. Resistance in vectors of human dise8se, particularly malaria-transmit ting mosquitoes, is a serious threat to public health in many nations. Agricultural productivity is jeopardized because of widespread resistance in crop and livestock pests. Serious resistance problems are also evident in pests of the urban environ ment, most notably cockroaches. Better understanding of pesticide resistance is needed to devise techniques for managing resistance (Le. , slowing, preventing, or reversing development of resistance in pests and promoting it in beneficial natural enemies). At the same time, resistance is a dramatic example of evolution. Knowledge of resistance can thus provide fundamental insights into evolution, genetics, physiology, and ecology. Resistance management can help to reduce the harmful effects of pesticides by decreasing rates of pesticide use and prolonging the efficacy of environmentally safe pesticides. In response to resistance problems, the concentration or frequency of pesticide applications is often increased. Effective resistance management would reduce this type of increased pesticide use. Improved monitoring of resis tance would also decrease the number of ineffective pesticide applications that are made when a resistance problem exists but has not been diagnosed. Resistance often leads to replacement of one pesticide with another that is more expensive and less compatible with alternative controls.

The sterile insect technique (SIT) is an environment-friendly method of pest control that integrates well into area-wide integrated pest management (AW-IPM) programmes. This book takes a generic, thematic, comprehensive, and global approach in describing the principles and practice of the SIT. The strengths and weaknesses, and successes and failures, of the SIT are evaluated openly and fairly from a scientific perspective. The SIT is applicable to some major pests of plant-, animal-, and human-health importance, and criteria are provided to guide in the selection of pests appropriate for the SIT. In the second edition, all aspects of the SIT have been updated and the content considerably expanded. A great variety of subjects is covered, from the history of the SIT to improved prospects for its future application. The major chapters discuss the principles and technical components of applying sterile insects. The four main strategic options in using the SIT — suppression, containment, prevention, and eradication — with examples of each option are described in detail. Other chapters deal with supportive technologies, economic, environmental, and management considerations, and the socio-economic impact of AW-IPM programmes that integrate the SIT. In addition, this second edition includes six new chapters covering the latest developments in the technology: managing pathogens in insect mass-rearing, using symbionts and modern molecular technologies in support of the SIT, applying post-factory nutritional, hormonal, and semiochemical treatments, applying the SIT to eradicate outbreaks of invasive pests, and using the SIT against mosquito vectors of disease. This book will be useful reading for students in animal-, human-, and plant-health courses. The in-depth reviews of all aspects of the SIT and its integration into AW-IPM programmes, complete with extensive lists of scientific references, will be of great value to researchers, teachers, animal-, human-, and plant-health practitioners, and policy makers.

Blood-sucking insects are the vectors of many of the most debilitating parasites of man and his domesticated animals. In addition they are of considerable direct cost to the agricultural industry through losses in milk and meat yields, and through damage to hides and wool, etc. So, not surprisingly, many books of medical and veterinary entomology have been written. Most of these texts are organized taxonomically giving the details of the life-cycles, bionomics, relationship to disease and economic importance of each of the insect groups in turn. I have taken a different approach. This book is topic led and aims to discuss the biological themes which are common in the lives of blood-sucking insects. To do this I have concentrated on those aspects of the biology of these fascinating insects which have been clearly modified in some way to suit the blood-sucking habit. For example, I have discussed feeding and digestion in some detail because feeding on blood presents insects with special problems, but I have not discussed respiration because it is not affected in any particular way by haematophagy. Naturally there is a subjective element in the choice of topics for discussion and the weight given to each. I hope that I have not let my enthusiasm for particular subjects get the better of me on too many occasions and that the subject material achieves an overall balance.

Mosquitoes and black flies are a constant threat to health and comfort, yet the modern chemical pesticides used to control them have cre ated serious ecological problems. Populations of resistant mosquitoes and black flies have evolved, beneficial insects and natural predators have been destroyed, and environmental pollution has increased worldwide. Therefore, scientists have energetically sought new, environmentally safe technologies to combat mosquitoes and black flies and the diseases they carry. Among the most effective alternative means of controlling these pests are the highly spe cific microbial agents derived from Bacillus tburingiensis or Bacillus spbaericus. The microbial control of mosquitoes and black flies is a very important, rapidly developing area of science. Entomologists and microbiologists have already achieved spectacular successes using B. tburingiensis and B. spbaericus against these pests. Recent discoveries of new bacterial isolates specific to new hosts and recent genetic improvements in these isolates have created the potential for wide-scale use of these biological control agents. Efficient microbial control of mosquitoes and black flies can now be achieved, but a proper knowledge of factors relating to the safe and effective use of these biological control agents is necessary. The efficacy of B. tburingiensis and B. spbaericus is influenced by the inherent differential tol erance of the target mosquitoes or black flies, by the formulation technology and application of these agents, and by environmental factors, especially sun light and temperature.

The Third Edition of this popular reference work describes the methods and rationale for sampling mosquitoes. Originally written by Professor M. W. Service, the book has been updated by John B Silver. More than 1,000 new references have been added and out-of-date material has been removed. The book emphasizes the ecology and behavior of those species that play a role as vectors of human and animal diseases and infections. Designed to serve as a practical reference for field entomologists and mosquito control specialists, it describes sampling methods and trapping technologies and tools for the collection of mosquitoes from egg to adult.

This book gathers contributions by 39 international specialists on well-known but neglected mosquito-borne diseases. The authors highlight pathogens that are increasingly being spread worldwide by various mosquito species, a situation worsened further by migration and tourism. The book addresses significant agents of diseases like AIDS, dengue, Zika virus, malaria and even cancer, and the risk of transmission via mosquito-related vectors. In addition, it examines important means of preventing the outbreak of related diseases by using insecticides and/or repellents. A particular focus is on the unique and sophisticated mouthparts of bloodsucking species, which allow them to feed on blood in an undisturbed manner, and by means of which agents of disease can enter potential human and animal hosts. In brief, the book provides a broad range of information for a wide readership, including graduates, teachers and researchers in the fields of parasitology, virology, tropical medicine and microbiology, as well as practitioners and healthcare officials.

Over 98% of sprayed insecticides and 95% of herbicides reach a destination other than their target species, including non-target species, air, water and soil. The extensive reliance on insecticide use reduces biodiversity, contributes to pollinator decline, destroys habitat, and threatens endangered species. This book offers a more effective application of the Integrated Pest Management (IPM) approach, on an area-wide (AW) or population-wide (AW-IPM) basis, which aims at the management of the total population of a pest, involving a coordinated effort over often larger areas. For major livestock pests, vectors of human diseases and pests of high-value crops with low pest tolerance, there are compelling economic reasons for participating in AW-IPM. This new textbook attempts to address various fundamental components of AW-IPM, e.g. the importance of relevant problem-solving research, the need for planning and essential baseline data collection, the significance of integrating adequate tools for appropriate control strategies, and the value of pilot trials, etc. With chapters authored by 184 experts from more than 31 countries, the book includes many technical advances in the areas of genetics, molecular biology, microbiology, resistance management, and social sciences that facilitate the planning and implementing of area-wide strategies. The book is essential reading for the academic and applied research community as well as national and regional government plant and human/animal health authorities with responsibility for protecting plant and human/animal health.

The new series "Microbiology Monographs" begins with two volumes on intracellular components in prokaryotes. In this first volume, "Inclusions in Prokaryotes", the components, labeled inclusions, are defined as discrete bodies resulting from synthesis of a metabolic product. Research on the biosynthesis and reutilization of the accumulated materials is still in progress, and interest in the inclusions is growing. This comprehensive volume provides historical background and comprehensive reviews of eight well-known prokaryotic inclusions.
