Horticultural sector presents many opportunities for economic development and improving livelihood of growers but several factors constrain production and limit the potential for trade of fruits and vegetables. Tephritid fruit flies constitute a major constraint. They cause enormous losses through direct feeding damage and loss of market opportunities through imposition of quarantine restrictions by importing countries to prevent entry and their establishment. In Africa, several native (Ceratitis and Dacus spp) and exotic (Bactrocera and Zeugodacus spp.) species inflict considerable losses to horticulture causing losses ranging from 30-90%. Over the past 10 years of R&D, extensive information has been generated on bioecology and management of several native and exotic fruit flies in Africa. While several specific reviews have addressed various aspects of the biology, ecology and management of economically important tephritid fruit flies; coverage of African native species has been limited largely to Bactrocera oleae and Ceratitis capitata – which are not economically important species in many Africa countries. Indeed, no book exist that have explicitly addressed economically important African fruit flies and none of the various reviews, have specifically focused on the status of the bioecology, economic impact and management of exotic and native fruit flies – including several potentially invasive Dacus species attacking vegetables - in Africa. This book consolidates this status of knowledge and socio-economic impact of various intervention techniques that are currently being applied across Africa. The timing of the book is especially pertinent due to the changing fruit fly landscape in Africa – caused by arrivals of the highly destructive alien invasives (Bactrocera dorsalis, B. zonata, and B. latifrons) - and the priorities African countries have placed recently on export of fruits and vegetables to international markets. This is an important reference material for researchers, academics and students that are keen at improving horticulture and enhancing food and nutrition security in Africa and beyond.

Chronobiology is the study of timing mechanisms in biological systems as diverse as plants, animals and some micro-organisms. It includes rhythmic phenomena ranging from short period (ultradian) through daily (circadian) to long period (monthly, annual) cycles of behaviour, physiology and biochemistry. In recent years spectacular advances have been made, particularly in the field of circadian rhythms, and hardly a week passes without important papers appearing in the major scientific journals. The third edition of Insect Clocks , like its predecessors, deals with the properties and functions of clock-like processes in one of the planet's most abundant groups of organisms. The first half of the book is concerned with circadian rhythmicity, the second with annual responses such as over-wintering diapause, seasonal morphs and cold hardiness. Insect Clocks puts modern developments in these fields into a secure framework of the 'classical' literature that has defined the subject. The book is directed at active researchers in the field as well as newcomers and scientists working in many other areas of modern biology. It will also serve as a textbook for advanced and less advanced students and should find its way into university libraries wishing to keep abreast of the times.

Finally, two new species, Neoblastobasis laikipiae and Blastobasis mpala, are known only from black light samples. DNA barcodes augmented the ability to discriminate between some closely related species within several genera. Male specimens of Blastobasis kenya, B. acirfa, and B. aynekiella and some associated female conspecifics, in particular, had distinctly different barcodes but were not initially diagnosed using standard morphological features. Subsequently, corroborative morphological features were found to support the DNA barcode data, and both data are discussed herein. Lectotypes are designated for Blastobasis arguta Meyrick, 1918; B. byrsodepta Meyrick, 1913; B. egens Meyrick, 1918; B. eridryas Meyrick, 1932; B. extensa Meyrick, 1918; B. indigesta Meyrick, 1931; B. industria Meyrick, 1913; and B. trachilista Meyrick, 1921.

Insect trapping is a basic field research tool for many biologists, whether they are studying insect pests, disease vectors or insect ecology for its own sake. Any field entomologist contemplating a new insect trapping program or looking to improve or develop an existing scheme will benefit from this broad review of flying insect traps, in which the author draws on a wide variety of methods used by different research projects from all over the world. Over the years a great many traps have been developed and endlessly modified to suit particular species, habitats, and research requirements. In virtually every case the design of the trap interacts with the specific behavior of the insects involved to bias trap efficiency. In addition, the limited dialogue between workers in different subject disciplines and habitats has caused a shortage of new information available to field entomologists as a whole. Describes and evaluates the main methods of trapping flying insects Brings together results from agricultural/forest/pest studies and those from medical entomology

FROM THE PREFACE: The idea of Integrated Pest Management (IPM) is not a new one, and since the term was first coined, it has come to achieve a range of different meanings. In its simplest form it is accepted as being a control strategy in which a variety of biological, chemical and cultural control measures are combined to give stable long term pest control. In its recent renaissance, IPM has more often been taken to describe more biologically oriented pest control strategies that have arisen following problems with purely chemical control. It is the purpose of the first six chapters of this book to consider fundamental principles for IPM development, and to outline current research progress and future research needs, in the light of technological developments and agricultural requirements. The final seven chapters of the book deal with the practical aspects of IPM implementation. The range of crop types considered represent the diversity of crop production and storage systems in Western Europe, with different ecological backgrounds, against which IPM might operate, and within which IPM has developed to differing extents.
