Book excerpt: Excerpt from The Biological Control of Mealybugs Attacking Citrus Great difficulty has always been experienced in the attempt to control these insects on citrus trees. The ordinary methods of control for scale insects, fi.e., Spraying and fumigation, have uniformly failed to bring relief, even when applied at much greater strength than has been necessary to handle satisfactorily such pests as the black, red, and purple scales. Much experimental work has been carried out. By the United States Department of Agriculture, the Citrus Experiment Station, and the County Agricultural Commissioners, in the hope of discovering improved methods or more satisfactory insecticides for the purpose, but the resistance of these insects has been so great that it has seemed practically impossible to destroy them without seriously damaging the tree and fruit. The situation led entomologists to give consideration to radically different methods for the suppression of mealybugs, and out of this has come the biological method, the discussion of which is the pri mary object of this bulletin.

This book was released on 2018-03-18 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Natural Control of the Citrus Mealybug in Florida These entomogenous fungi are worth millions of dollars to the citrus industry. Owing to their excellent work, oranges and grape fruit are grown at a profit in many parts of the State where no money whatsoever is spent on artificial remedial measures. It should not be inferred that spraying to control citrus pests is not advised. A greater profit can be enjoyed when sprays are employed judiciously, particularly if they are utilized in a way to supplement the work of the fungi, but citrus fruits can be grown at a profit in the absence of any artificial measures, a condition probably not possible, for ih stance, in the apple industry. The inestimable value of the entomo genous fungi to the citrus grower of Florida is thus evident. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Download or read book The Common Mealybug and Its Control in California written by Russell Sage Woglum and published by . This book was released on 1917 with total page 20 pages. 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

This book was released on 2017-10-28 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Biology and Control of Citrus Insects and Mites Earlier bulletins published by the University of California on citrus insects have been out of print for several-years, and the aim of the present publication is to replace in part those earlier bulletins, for which there has been a constant demand, as well as to bring the subject Of citrus-insect control in California up to date. Since many of the requests call for detailed information on the biology of the pests, and because such information is least available, it seems desirable to cover that phase of the subject as adequately, as the limited space in this publica tion will allow. The order of discussion of the pests is more or less in accordance with their classification as they occur in the animal kingdom, and not necessarily in accordance with their relative importance as pests of citrus.

Available in PDF, EPUB and Kindle. Book excerpt: As well as examining successful biological control programmes this book analyses why the majority of attempts fail. Off-target and other negative effects of biological control are also dealt with. Chapters contributed by leading international researchers and practitioners in all areas of biological control afford the book a breadth of coverage and depth of analysis not possible with a single author volume. Combined with the use of other experts to review chapters and editorial oversight to ensure thematic integrity of the volume, this book provides the most authoritative analysis of biological control published. Key aspects addressed include how success may be measured, how successful biological control has been to date and how may it be made more successful in the future. With extensive use of contemporary examples, photographs, figures and tables this book will be invaluable to advanced undergraduate and postgraduate students as well as being a `must' for all involved in making biological control successful.
