Available in PDF, EPUB and Kindle. Book excerpt: "No one method for the control of the common mealy bug can be recommended under all conditions. The remedy or remedies to be used will depend upon whether the trees are in house lots or orchards, whether few or many, and the infestation light or severe. In the case of sever infestation it will depend also upon the kind of fruit. This insect infects oranges of all varieties, grapefruit, lemons, and all other kinds of citrus fruit grown in California, causing deformity, weakening and dropping of much immature fruit, and the discoloration and weakening of the rind of the fruit maturing. This bulletin discusses the three remedies which have been widely used : namely, fumigation, spraying, and the artificial spread of insect enemies, points out the sphere of usefulness of each method, and shows, on pages 14-15, how they may be combined so as to secure complete control. An important part of the procedure recommended is the banding of trees with a mixture consisting of sulphur and a sticky material used to protect trees from insects. This keeps off the Argentine ant and other ants which attend and foster the mealybug and hinder or prevent the good work of insect enemies which otherwise might hold it in check. The method of preparing the mixture and applying the bands is described on pages 12-13. Where insect enemies are few or absent, or where they are themselves heavily parasitized, the trees should be sprayed or fumigated, and colonies of effective enemies should be introduced."--Page 2

Download or read book To Make a Spotless Orange written by Richard C. Sawyer and published by Wiley-Blackwell. This book was released on 1996 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: An Australian ladybug imported in the 1880s was a remarkable success against scale insects that had ravaged the orange groves of California. Subsequently, entomologists developed both theory and practice of biological control more fully in California than in any other state. In state government agencies, and later in the University of California, the biological control program grew, even as farmers and scientists elsewhere rushed headlong into chemical methods. Author Richard Sawyer shows that biological control thrived in California precisely because its practitioners had close ties to the citrus industry. They aimed to maximize profits by producing cosmetically perfect fruit. Entomologists, such as Harry S. Smith, a central figure of this study, saw themselves as pragmatists. Because of their position in applied science, biological control workers did not focus on making fundamental discoveries. Yet, as this study reveals, technological need led the Californians to "pure science" investigations in population dynamics, insect reproduction and development, and taxonomy. Sawyer supports the argument that technology often leads to science rather than always following science. Sawyer has mined a wealth of resources, including scientific publications; government documents; federal, state, university, and corporate archives; and interviews with key participants or their relatives. Scholars and students of agricultural history, history of science, environmental history, history of ecology and of biology, California history, and entomology will find common interests in this account of a minority approach to a major technological problem.
