The Distribution And Host Plants Of Fruit Flies Diptera Tephritidae In Australia

Throughout Asia, Australia and the Pacific, and increasingly in Africa, the primary horticultural insect pests are fruit flies belonging to the genera Bactrocera, Zeugodacus and Dacus (Diptera: Tephritidae: Dacini). The Dacini is a hugely diverse clade of nearly 900 species endemic to the rainforests of Asia, Australia and the western Pacific, and the savannas and woodlands of Africa. All these species lay their eggs into fleshy fruits and vegetables, where the maggots feed, therefore destroying the fruit. In addition to being crop pests, dacines are also invasive pests of major quarantine importance and their presence in production areas can significantly impact market access opportunities. This broad text provides a rapid introduction to this economically and ecologically important group, which includes species such as the Oriental fruit fly (B. dorsalis), Melon fly (Z. cucurbitae), Queensland fruit fly (B. tryoni) and the Olive fly (B. oleae). Broken into three primary sections, it first explores the evolutionary history, systematic relationships, taxonomy and species-level diagnosis of the Dacini flies. The following biology section covers their life history, population demography, behaviour and ecology, and natural enemies. The final section of the book covers the management of these flies, with chapters on pre-harvest, post-harvest and regulatory controls. Each chapter concludes with a list of key monographs, papers or book chapters for further reading. This book will be of interest to field entomologists, extension officers, quarantine officers and market access negotiators, as well as students of applied entomology and pest management.

The book is a taxonomic treatise of the tropical fruit flies of Papua New Guinea, Indonesian Papua, associated islands and Bougainville, the region of the world where speciation in the sub-family Dacinae has been most prolific. The book aims to provide readers with an updated record of all known species of Dacinae that occur in this geographic area including descriptions of 65 new species out of an entire list of 296 known species covered. It provides a discussion on the evolutionary origins of the Dacinae and a key to the genera and sub-genera recorded in the Australian-Pacific Region. Further, the major pest species and their biosecurity risks to other countries are discussed. Extensive field research by the authors and colleagues over many years has resulted in the accumulation of advanced knowledge of the tropical fruit flies in this region. A key reference for researchers of taxonomy, ecology and pest management in the family Tephritidae worldwide. Useful for biosecurity and horticulture workers in Agriculture Departments within government administration and universities around the world.

As global warming and species migration become more prevalent issues, there is an urgent need for a text that provides comprehensive taxonomic details and geographic distributions of Dacinae fruit flies within south-east Asia. In particular, some of the major pest species of this region are being introduced on a regular basis to new geographical areas, causing widespread food security issues and economic hardship. Quarantine and horticultural organizations require detailed information on these fruit fly species in order to detect and eradicate any new incursions. This major new reference work details the taxonomic research into the subfamily Dacinae, which contains the tropical fruit flies of south-east Asia, as well as many other regions of the world. While focusing on south-east Asian fauna, all known species are included, through a study of the type material available in museums around the world. Specimens collected in major surveys conducted across Asia from 1983 to present have also been used to ensure a complete, in-depth review of this subfamily. Providing complete descriptions and artwork of all species of Dacinae recorded from the south-east Asian region for the first time, this book is written and illustrated by experts with over 80 years' combined research experience. Areas covered include: India, Bhutan, Nepal, Sri Lanka, Myanmar, China, Taiwan, Japan, the Philippines, Palau, Vietnam, Thailand, Singapore, Malaysia and Indonesia. It is an essential reference for departments of agriculture, researchers and students of entomology and quarantine, horticultural and chemical industry personnel worldwide. Key features: - 120 recently discovered species - 500 detailed drawings - Revision of all known species - Updated geographical distributions and host records - Accurate list and detailed information of all known pest species This book will be followed by Keys to Fruit Flies of South-East Asia.

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.

Insects are by far the most diverse and abundant animal group with respect to the number of species globally, in ecological habitats and in biomass. The ecological and evolutionary success of insects depends in part on their countless relationships with beneficial microorganisms, which are known to influence all aspects of their physiology, ecology, and evolution. These symbiotic associations are known to: (a) enhance nutrient-poor diets, (b) aid digestion of recalcitrant food components, (c) protect from predators, parasites, and pathogens, (d) contribute to inter- and intraspecific communication, (e) affect efficiency as disease vectors and (f) govern mating and reproductive systems. Characterization, exploitation, and management of the insect-bacterial symbiotic associations can contribute significantly to the control of agricultural pests and disease vectors. Insects that depend exclusively on nutritionally restricted diets such as plant sap, vertebrate blood, and woody material, commonly possess obligate mutualistic endosymbionts involved in the provision of essential nutrients or in the degradation of food materials. These intracellular mutualists commonly have the following biological features: (a) they localize inside bacteriocytes, (b) are essential for fitness, (c) are maternally transmitted, and (d) display strict host-symbiont co-evolutionary patterns. In addition to obligate endosymbionts, many insects harbor bacteria that are not essential for their survival or fecundity and are typically maintained with a patchy distribution in host populations. Such symbionts can induce reproductive phenotypes in insect hosts, including male-killing, feminization, parthenogenesis or cytoplasmic incompatibility. Because these bacteria manipulate their host’s reproductive biology, they also likely accelerate host processes. As for essentially all animals, microbial communities are particularly prominent in the digestive tract, where they may be key mediators of the varied lifestyles of insect hosts. The contribution of microorganisms, particularly gut microorganisms, to insect function is highly relevant from several perspectives, linking to applications in medicine, agriculture, and ecology. Gut-associated microorganisms can include protists, fungi, archaea, and bacteria, but it is generally accepted that bacterial species dominate the microbial community in the guts of most insects. Gut-associated bacteria can influence: (a) vectoring efficiency, (b) developmental time, (c) decomposition of plant biomass and carbon cycle, (d) nitrogen fixation and nitrogen cycle, (e) mating incompatibilities, and (f) detoxification of pesticides leading to the acquisition of insecticide resistance.

The Handbook identifies all aspects of Regulatory Plant Biosecurity and discusses them from the standpoint of preventing the international movement of plant pests, diseases and weeds that negatively impact production agriculture, natural plant-resources and agricultural commerce.
