Download or read book Briefe ber Blattminierer Letters on Leaf Miners written by E.M. Hering and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: My association with Prof. Hering extends over the past seventeen years, and during this period I have visited him at his home on more than forty occasions and received over 300 letters from him. These letters contain much detailed entomological information. They also throw considerable light on Prof. Hering's personality and character and the background against which he worked. The publication of at least part of these letters as a final tribute to Prof. Hering has been in my mind for many years. This original idea has now been somewhat extended by the inclusion of a number ofletters to Dr. H. Buhr, Dr. J. Klimesch, Dr. F. Groschke and G. C. D. Griffiths, all of whom shared Prof. Hering's interest in leaf-miners. Although Dr. Buhr is primarily a botanist, with Hering's encour agement he has taken an active interest in leaf-miners throughout his career and his remarkable collecting becomes apparent from Hering's letters to him. For many years Prof. Hering has written between two and three thousand letters annually. It has obviously been possible to consider here only a very small proportion of these. From many of the longer letters only isolated paragraphs have been included. Use of italics in the letters was not entirely consistent and has been reproduced as used by Prof. Hering. Selection of the letters has been based primarily on their entomolo gical interest but numerous passages have also been included illustra ting in some way Hering's personal qualities.

Available in PDF, EPUB and Kindle. Book excerpt: Fruit flies are enormously important economic pests, as California has learned over the past few years (remember the Mediterranean Fruit Fly?). The problem is expected to get worse, and issues of both basic research and control measures are very important for this pest. This book is the edited, camera-ready proceedings of a recent international symposium on fruit flies of economic importance. It covers current knowledge of fruit fly physiology, genetics, morphology and behavior. It discusses action programs for controlling and using fruit flies in agronomy, as well as the problem of fruit flies in the fruit growing industry.

Available in PDF, EPUB and Kindle. Book excerpt: Volume 5 of "Insect-Plant Interactions" is a volume in a series that presents research in the field. Topics covered include chemical changes in plants as a result of insects feeding on their leaves, dynamic elements of the use and avoidance of host plants by tephritid flies as a result of the presence of other flies, floral volatiles in insect biology, endophytic fungi as mediators of plant insect interactions, the cost of chemical defence against herbivory, and life history traits on insect herbivores in relation to host quality. The book also presents the first available review on physicochemical conditions of the gut lumen from an ecological perspective.

Available in PDF, EPUB and Kindle. Book excerpt: Here is a new single-volume guide that provides complete discussion of the use of electrophoresis in studies of agricultural pests. It includes contributions from many noted experts in this field, giving the latest information on the study of populations, structure and familial relationships, migration and gene flow, taxonomy, evolution, biotype discrimination and host adaption, resistance to pesticides, the use of electrophoresis to assess parasitism of insects by Hymenopterous parasitoids in biological control programs, and the diets of insect predators. This unique reference covers a wide range of pest organisms from insects, slugs and birds to mammals, and offers insights into such techniques as conventional slab electrophoresis of proteins and enzymes, isoelectric focusing, 2-D electrophoresis, and electrophoresis of DNA, including DNA fingerprinting techniques.
