Book Description
"Besides describing this scale insect and its life history and habits, this bulletin shows how it is spread from orchard to orchard and from region to region, lists its numerous food plants, discusses the parasitic and other insect enemies which help in controlling it, and describes fully the preparation and application of the sprays which are used most successfully in the warfare against it."--Page 2

Book Description
This text presents an up-to-date account of the soft-scale insects, "Coccidae", and covers almost the entire spectrum of the knowledge of this insect family. It is divided into three sections, covering: soft scale insects; their natural enemies; and damage and control.

Book Description
The development of resistance to pesticides is generally acknowledged as one of the most serious obstacles to effective pest control today. Since house flies first developed resistance to DDT in 1946, more than 428 species of arthropods, at least 91 species of plant pathogens, five species of noxious weeds and two species of nematodes were reported to have developed strains resistant to on~ or more pesticides. A seminar of U. S. and Japanese scientists was held in Palm Springs, California, during December 3-7, 1979, under the U. S. -Japan Cooperative Science Program, in order to evaluate the status of research on resistance and to discuss directions for future emphasis. A total of 32 papers were presented under three principal topics: Origins and Dynamics of Resistance (6), Mechanisms of Resistance (18), and Suppression and Management of Resistance (8). The seminar was unique in that it brought together for the first time researchers from the disciplines of entomology, plant pathology and weed science for a comprehensive discussion of this common problem. Significant advances have been identified in (a) the development of methods for detection and monitoring of resistance in arthropods (electrophoresis, diagnostic dosage tests) and plant pathogens, (b) research on biochemical and physiological mechanisms of resis tance (cytochrome p450, sensitivity of target site, gene regulation), (c) the identification and quantification of biotic, genetic and operational factors influencing the evolution of resistance, and (d) the exploration of pest management approaches incorporating resis tance-delaying measures.
