Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The California Species of Mealy Bugs The systematic literature dealing with certain groups of the Coccidae or scale insects is extremely unsatisfactory, this condition being especially pronounced in the case of those groups commonly called the "soft scales." The present author (4) has stated in an earlier paper that ." . . of the nearly 100 species of mealy bugs thus far described from North America, including some 35 from California, not more than three or four are recognizable at all on the basis of the published descriptions if taken apart from their typical host and their type locality," nor at the time of the present writing does this statement need any extensive modification. A few species have been described since the statement was originally made and to some of these it may not apply, but so far as the species known at that time arc concerned, the additional claim may safely be made that even under the optimum conditions cited, the identification of many of our species can not be accomplished with reasonable certainty. The actuating motive of the present paper has been the hope of remedying this condition as far as may be for those species of mealy bugs occurring in California. However, progress toward this goal has been made possible only by the utilization of certain methods not ordinarily employed, at least by American entomologists, and by the emphasizing of certain morphological features of which some have been entirely overlooked and of which the full significance of none seems at any time to have been realized. The scope of the paper has therefore been extended to include an explanation of these methods and a description of these morphological features. The restriction of the paper to those species occurring in California has not been due to any desire to keep within the boundaries of some artificially defined political unit nor to any belief that the California mealy-bug fauna is at all separable as a group from that of the rest of North America. The limitations imposed have been purely those of convenience. It so happens that most of the species known from west of Colorado and New Mexico have been described from California and that the types of these are for the most part in western collections.

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 24 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." -- p. [2]

This book was released on 2009-08-28 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: For nearly 50 years, pest control was mostly based on broad-spectrum conv- tional insecticides such as organochlorines, organophosphates, carbamates and pyrethroids. However, the severe adverse effects of pesticides on the environment, problems of resistance reaching crisis proportions and public protests led to stricter regulations and legislation aimed at reducing their use. Ways to reduce the use of synthetic pesticides in plant protection and to use more alternative and novel me- ods for pest control or biorational control are the challenges of pest control for the twenty-first century. The term biorational (biological + rational) pesticides can be defined as the use of specific and selective chemicals, often with a unique modes of action, that are compatible with natural enemies and the environment, with minimal effect on n- target organisms. Biorational control is based on a diversity of chemical, biological and physical approaches for controlling insect pests which results in minimum risk to man and the environment.

Download or read book The Humane Gardener written by Nancy Lawson and published by Chronicle Books. This book was released on 2017-04-18 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this eloquent plea for compassion and respect for all species, journalist and gardener Nancy Lawson describes why and how to welcome wildlife to our backyards. Through engaging anecdotes and inspired advice, profiles of home gardeners throughout the country, and interviews with scientists and horticulturalists, Lawson applies the broader lessons of ecology to our own outdoor spaces. Detailed chapters address planting for wildlife by choosing native species; providing habitats that shelter baby animals, as well as birds, bees, and butterflies; creating safe zones in the garden; cohabiting with creatures often regarded as pests; letting nature be your garden designer; and encouraging natural processes and evolution in the garden. The Humane Gardener fills a unique niche in describing simple principles for both attracting wildlife and peacefully resolving conflicts with all the creatures that share our world.
Download or read book Polyphagous Pests of Crops written by Omkar and published by Springer Nature. This book was released on 2021-01-04 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polyphagous pests are primarily agricultural pests that feed on economically important agricultural and horticultural crops of wide taxonomic diversity across the globe. They cause immense damage across different crop varieties owing to their generalist and voracious food habits. The advent of mono-crop culture in a huge area and the massive use of pesticides post green revolution have massively increased pest outbreaks all over the world. The Middle Eastern countries, African continent and even the Indian subcontinent is increasingly facing resurgences of polyphagus pests. This book compiles an inclusive account of polyphagous pests. It covers locusts, termites, aphids, whiteflies, mealybugs, scale insects, gram pod borer, fall armyworm, thrips, mites and rodents. The book discusses mode of spread, enormity of losses caused, mechanism of action, and also means to reduce the crop losses. It brings together a unique perspective for researchers to learn effective pest management practices across all crops. This book is a reference guide to researchers and also useful for academicians and students of entomology.
