NEMATOLOGY BOOKS
PLANT AND NEMATODE INTERACTIONS

An excellent monograph titled “Plant and Nematode Interactions” (Agronomy Monograph 36) has been prepared by K. R. Barker, G. A. Pederson, and G. L. Windham and published by the American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America. The first introductory chapter of this book provides a condensed history of Plant Nematology with an overview of the challenging research opportunities that the Science of Nematology offers for the future. The following 13 chapters of the book contain informative reviews of several aspects of Plant Nematology including biology and systematics, ecology, parasitism, population dynamics, interactions with other pests, and management of phytonematodes. The most effective nematode management strategies are clearly presented in these chapters and include cropping systems, chemical control approaches, classic breeding methods for the selection of resistant varieties with explanation of the genetic mechanisms regulating the resistance of plants to nematodes, and advanced biotechnolgies for bioengineering nematode resistant crops. Basic concepts of sustainable agriculture, integrated pest management, and information transfer conclude the first section on general Plant Nematology.
The second section of the book covers applied Plant Nematology and provides updated and detailed information on nematode problems, their diagnosis, and management practices for the major field, vegetable, and fruit crops grown in the United States. The efforts made by the authors (all from the United States) to cover the international literature is commendable; however, certain topics presented in these chapters focus mainly
on American nematode problems, which may differ from those in other parts of the world. Damaging nematode species for certain crops in regions other than the United States are missed or covered insufficiently. Nematode diseases of tropical crops and other crops of economic importance in the Middle East and in the Mediterranean areas are not included in the book. The quality of the illustrations is acceptable taking into consideration the low cost of the book. One figure is mislabeled. This monograph contains updated Plant Nematology information, which is extremely useful for teachers, students, agricultural specialists, and persons involved in pest management. “Plant and Nematode Interactions” can be obtained for US $ 55.00 + mailing costs from ASA, CSSA, SSSA Headquarters office; Attn: Book order Department; 677 South Segoe Road;

ATLAS ON ULTRASTRUCTURE OF INFECTIVE JUVENILES
OF THE SOYBEAN CYST NEMATODE, HETERODERA GLYCINES

A monograph titled “Atlas on Ultrastructure of Infective Juveniles of the Soybean Cyst Nematode, Heterodera glycines” (Agriculture Handbook Number 711) was prepared by B. Endo and published by the United States Department of Agriculture. This monograph provides detailed illustrations of the ultrastructural details of the external and internal anatomy of juvenile stages of the soybean cyst nematode, Heterodera glycines. The abstract that the author prepared for this outstanding publication follows: “This atlas shows the transition from preparasitic to parasitic juveniles and their relation to host tissues, which become modified to form syncytia as specialized feeding sites. The electron micrographs are grouped into subunits to emphasize various features of the nematode and host-parasite interactions. Subunits include the stomatal region, the anterior neurosensory organs, esophagus and associated glands, and the intestine. Illustrations also include changes in nematode
anatomy related to nematode development and early host responses. This handbook is a comprehensive compilation of previously published electron micrographs, combined with new data. The atlas is an educational tool for those interested in nematode morphology and a reference for researchers interested in applying physiological studies to functional units of the nematode”. The author informs that while supplies last, single copies of this publication may be obtained at no cost from: Nematology Laboratory, USDA-ARS, 10300 Baltimore Avenue, Building 011A, Room 165B, Beltsville MD 20705-2350. Copies may be purchased from the National Technical Information Service, 5285 Port Royal Road, Springfield VA 22161, phone (703) 605-6000.

BACK ISSUES OF JOURNAL OF NEMATOLOGY VOL. 1-26 &
ADVANCED TREATISE ON MELOIDOGYNE

Safia Siddiqi, Chairperson of the Communication and Information Exchange Committee of the International Federation of Nematology (IFNS) has provided the following information:The Society of Nematologists is offering the remaining back issues of the Journal of Nematology, Vol. 1-26. for the cost of shipping and handling. Also, North Carolina State University is offering the books titled “Advanced Treatise on Meloidogyne” volumes 1 and 2, which can be included in the same shipment. Because several issues of the early volumes of JON are out of print, early orders will be more complete than later orders. This offer will end on March 31st, 1999. The total shipping cost for the set of JON and the Advanced Treatise on Meloidogyne is US $70. The volumes will be sent uninsured and by surface mail. Delivery by surface mail may take 4 to 6 months in some areas of the world. Payment of US $70 by check (made payable to the Society of Nematologists and drawn on a U.S. bank) or credit card must accompany your order. Payments made by VISA or MasterCard should include the name as it appears on the card, card number, expiration date, and the signature. Invoices will not be provided. Order and accompanying payment are to be sent to the Society of Nematologists, P.O. Box 1897, Lawrence, KS 66044 – 8897 USA.
