The implementation of Integrated Pest Management (IPM) has been a great success in temperate areas, but its role in tropical regions is less known. The tropics face specific challenges, namely weather that impacts insect life cycles and pesticide application. Beginning by reviewing the current state of pests, biological and chemical control and emerging technologies, this book then addresses specific crops, providing an up-to-date, research-oriented overview of IPM in tropical regions. This book will be a useful resource to entomologists, agronomists, horticulturists, and environmental scientists, nature conservation in tropics. The book is aimed to serve as reference book for students, teachers, researchers, extension functionaries and policy planners associated with insect pest management in tropics. This book can also be used as supplementary reading material in graduate and post graduate courses.

A catalogue of the soft-scale insects of the world (Homoptera: Coccoidea: Cocidae) with data on geographical distribution, host plants, biology and economic importance. This catalogue lists 162 genera comprising 1090 species and subspecies which have been described since Linnaeus (1758) until the cutoff date of December 1991. Extensive data are presented on taxonomy, nomenclature, synonyms, geographical distribution, host plants, biology, and economic importance of the species. New combinations are established for 40 species. One species, namely Filippia subterranea Gomez-Menor Ortega, is newly synonymized with Lecanopsis formicarum Newstead.

This book is dedicated to the scientists whose professional devotion and accomplish ments in research on scale insects of the area made the compilation of this book possible. This book has two primary objectives: (1) to enable interested workers, who are not specialists of scale insects, to recognize and indentify these to families, genera and species; and (2) to provide information on the life cycle, host-plant range, natural enemies, geographical distribution, economic importance for each known species from Central Europe, and to provide a bibliography on each taxa covered. Scale insects are important pests of fruit and nut trees, forest vegetation, woody ornamentals, greenhouse and indoor plants. World-wide losses and increased production costs attributed to scale insects are estimated to reach $5 billion annually. It is difficult to recognize them because of their microscopic size and hidden habits. Identification of pest species enables plant growers to check appropriate reference sources for biological information and to select control methods.

Polyphagous pests are primarily agricultural pests that feed on economically important agricultural and horticultural crops of wide taxonomic diversity across the globe. They cause immense damage across different crop varieties owing to their generalist and voracious food habits. The advent of mono-crop culture in a huge area and the massive use of pesticides post green revolution have massively increased pest outbreaks all over the world. The Middle Eastern countries, African continent and even the Indian subcontinent is increasingly facing resurgences of polyphagus pests. This book compiles an inclusive account of polyphagous pests. It covers locusts, termites, aphids, whiteflies, mealybugs, scale insects, gram pod borer, fall armyworm, thrips, mites and rodents. The book discusses mode of spread, enormity of losses caused, mechanism of action, and also means to reduce the crop losses. It brings together a unique perspective for researchers to learn effective pest management practices across all crops. This book is a reference guide to researchers and also useful for academicians and students of entomology.

The armoured scale insects comprise the largest family, Diaspididae, in the superfamily Coccoidea. Several species of armoured scale insects, for example the California red scale and the pernicious scale, are of great economic importance as they are destructive pests to crops such as cassava, citrus, avocado, sugarcane, pineapple, as well as various forest trees and ornamentals. This catalogue provides an up-to-date data on three subfamilies, namely Aspidiotinae, Comstockiellinae and Odonaspidinae, covering 864 species placed in 118 genera, which have been described in the family since Linnaeus (1758), until December 2002, the cut-off date. This book is a synthesis and catalogue of all of the information published on these genera and species worldwide up to December 2002, and gives information on their correct scientific name, taxonomy, common names, synonyms, host plants, geographical distribution, natural enemies, biology, economic importance, and published references. This catalogue will be of major importance to scale insect students, crop protection specialists, quarantine officers and any entomologist who requires information about armoured scale insects, either for research or for control projects.
