DOWNLOAD EBOOKOf the natural enemies used in insect pest control, the parasitic Hymenopterahave been the most successful. Within this group, the Encyrtidaeare one of six families that have been employed in this way. In the past 10 years, two species of encyrtids have been used successfully against two severe pests in agriculture in Africa, the cassava mealybug and the mango mealybug. Among the encyrtids, almost all species of the tribe Anagyrini are primary endoparasitoids of mealybugs and are thus of potential importance in biological control. Within this context, recognition of Oriental anagyrini species should greatly facilitate their future use in biocontrol. In this volume, the 20 genera belonging to the Anagyrini, known to occur in the Oriental region, are defined by means of a dichotomous key and brief generic diagnoses. Biology and use in biocontrol are summarized for every genus and identification keys to the known Oriental species are provided. All species are defined by means of illustrations and brief diagnoses or full morphological descriptions, with 65 species being described as new. The known distribution and host range for every species is also provided, together with an annotated citation list. Two substantial appendices summarize the worldwide use of Encyrtidae in classical biological control and the species recorded as parasitoids of mealybugs.

DOWNLOAD EBOOKSoft Scale Insects is intended to be a further step towards providing comprehensive information on soft scale insects. Four or five decades ago, entomologists embarking on a study on soft scale insects would have encountered a scarcity of general text books or comprehensive treatise of the family, as a starting point for their research. At the time, the available knowledge and data were either scattered among numerous articles or regional monographs or were in obsolete books. It is hoped that this volume will cover almost the entire spectrum of the knowledge on the soft scale insect family, Coccidae. This book comprises six chapters and begins by discussing the natural enemies of soft scale insects, such as pathogens like entomopathogenic fungi; predators like coccineilidae and other coleoptera; and parasitoids like encyrtidae. It then discusses issues of damage and control, including pest status of soft scale insects and coccid pests of important crops. This book will be of interest to entomologists, horticulturists, zoologists, biologists, and those involved in general agricultural research.

DOWNLOAD EBOOKThis publication presents illustrated keys to the 19 families and 706 described genera of Chalcidoidea known to occur in the Nearctic region (minimally America north of Mexico, but also including those areas of Mexico generally considered as having a Nearctic insect fauna). The first three chapters provide an introduction to this superfamily of wasps, most of whose members are parasites of other insects; a review of chalcidoid morphology as related to terms used in the keys & diagnoses; and an overview of the superfamily, including a 41 couplet key to families. Each of the remaining 19 chapters reviews one family & includes sections on recognition, systematics & relationships, biology, literature, an annotated key to the Nearctic genera, and for larger families an index to genera based on couplet number. Over 1,800 line drawings & electron micrographs illustrate the keys. Annotations include references to existing keys to species, estimated number of species, and known distribution & host range in the region.

DOWNLOAD EBOOKThe Hymenoptera is one of the largest orders of terrestrial anthropods and compromises the sawflies, wasps, ants, bees and parasitic wasps. This book examines the current state of all major areas of research for this important group of insects, including systematics, biological control, behaviour and use in education.
