Book Description
Numbering more than nine thousand described species, ants rank among the most abundant and widespread groups. The collective weight of ants in tropical forests and grasslands may constitute as much as 10 to 15 percent of the animal biomass. Ground-dwelling ants are major invertebrate predators in some areas, and they also have profound effects on flora because of their prodigious ability to consume plants, disperse seeds, and enrich the soil. Interacting with other organisms at every level, ants are ubiquitous, diverse, easy to collect, and sensitive to environmental change -- all attributes that make them well suited to biodiversity studies. Written by thirty leading ant biologists, this comprehensive book describes procedures for surveying the diversity of ground-dwelling ants. It introduces a standardized protocol for collecting ant samples in any part of the world and for conducting repeated sampling over time, which enables researchers to analyze global and longterm patterns. Chapters compare ant diversity to the diversity of other organisms and explain the value of ant studies in monitoring ecosystem change in diverse regions, including Madagascar, Malaysia, India, and Brazil. Covering aspects of ant ecology and taxonomy, species identification, specimen preparation, and sources of sampling equipment, this book provides the necessary foundation for readers from a wide range of backgrounds. It is indispensable not only to ant researchers but also to entomologists, conservationists, students, land managers, and others who assess biodiversity or environmental impacts.

Book Description
With this edition of the manual, FAO is establishing a new procedure for the development of pesticide specifications in a transparent manner. The specifications may be used to provide an international point of reference against which products can be judged, either for regulatory purposes or in commercial dealings, thereby helping to prevent the trading, sale and use of inferior products, and will contribute towards public and environmental safety throughout the world, especially in developing countries

Book Description
Ants have always fascinated the nature observer. Reports from ancient Egypt and Mesopotamia indicate that ants interested humans long ago. Myrmecology as a science had its beginning in the last century with great naturalists like Andre, Darwin, Emery, Escherich, Fabre, Fields, Forel, Janet, Karawaiew, McCook, Mayr, Smith, Wasmann and Wheeler. They studied ants as an interesting biological phenomenon, with little thought of the possible beneficial or detrimental effects ants could have on human activities (see Wheeler 1910 as an example). When Europeans began colonizing the New World, serious ant problems occurred. The first reports of pest ants came from Spanish and Portuguese officials of the fifteenth and sixteenth centuries in Trinidad, The West Indies, Central America and South America. Leaf-cutting ants were blamed for making agricultural development almost impossible in many areas. These ants, Atta and Acromyrmex species, are undoubtedly the first ants identified as pests and may be considered to have initiated interest and research in applied myrmecology (Mariconi 1970).
