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.

This fully revised and updated second edition of Insect Pests of Potato now includes an opening section with a basic overview of agronomic and economic issues as they relate to potato production. It also features a new section that reviews potato production, as well as problems caused by insect pests and solutions to these problems, in all major potato-growing regions of the world. Further, a new section discusses theoretical foundations of potato pest management and includes chapters on ecological theory, evolutionary theory, and a case study on their applications to elucidate differences between Eastern and Western populations of Colorado potato beetle in North America. There is also a new chapter on the foundations of integrated pest management and their applications in controlling insect pests. The sections on the biology of main pests and on control methods now feature the latest information, including emphasis on recent advances in molecular biology and genomics. Information on the use of dsRNA technology for pest control is also included, as are new chapters on potato ladybirds and on hemipterous pests other than aphids and psyllids. This second edition provides improved integration and logical connections among chapters and expanded geographic scope of coverage making it the ideal reference on the topic. Fully revised and updated with new sections on potato-growing regions and theoretical foundations of potato pest management using ecological theory, evolutionary theory and relevant case study insights Contains improved integration and logical connections among chapters, expanded geographic scope of coverage, and scientific advances Emphasizes recent advances in molecular biology and genomics, including the use of dsRNA technology for pest control

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.
