The potato tuber moth Phthorimaea operculella (Lepidoptera: Gelechiidae) is the most important pest in potato production in the tropics and subtropics. Faced with serious and increasing problems due to the extensive use of chemical pesticides to control this pest, safer alternatives such as the use of entomopathogens are of growing interest. The research presented here focus on the efficient integration of the endemic granulovirus infecting the potato tuber moth (PoGV) as biopesticide into IPM strategies. The investigations include basic research on the granulovirus-host interaction and ecology which allows a comprehensive understanding of the system and how the system is influenced by environmental factors, and applied research to improve the virus mass propagation technique and the UV-stability of the virus. The results presented allow differentiation between conditions occurring in different agroecological regions for appropriate management of the virus.

This book contains four chapters. Chapter 1 is an introduction to moths. It describes their history, differences with butterflies and skippers, classification, camouflage, navigation, attraction to light, and migration. Moths are useful as bio-indicators, pollinators, dispersal of seeds and producers of useful products (silk). They are harmful as agricultural and stored-grain pests, but can be controlled biologically and with pesticides. Chapter 2 reports that among moth pests the potato tuber moth, Phthorimaea operculella Zeller, is considered one of the most important potato pests worldwide. In Chapter 3, the pathogenicity of three native isolates of the entomopathogenic fungus Beauveria bassiana were studied in different concentrations of P. operculella eggs. The most pathogenic isolate was determined on eggs in vitro. Chapter 4 highlights several case studies representing long-term field research results of moth pests in maize, Zea mays L., and sugar-beet, Beta vulgaris L.

Over the past 40 years, the SIP meetings have played a central role in the development of the field of insect-plant relationships, providing both a show-case for current research as well as a forum for the airing and development of influential new ideas. The 10th symposium, held 4-10 July 1998, in Oxford, followed that tradition. The present volume includes a representative selection of fully refereed papers from the meeting, plus a listing of the titles of all presentations. The volume includes reviews of major areas within the subject, along with detailed experimental studies. Topics covered include central neural and chemosensory bases of host plant recognition, integrative studies of insect behaviour, tritrophic interactions, plant defences, insect life histories, plant growth responses, microbial partners in insect-plant associations, and genetic bases of host plant associations. The book provides a key source for students and research workers in the field of insect-plant relationships.
