This book was released on 1999 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: The onion thrips, Thrips tabaci Lindeman (Thysanoptera: Thripidae) is a worldwide pest of onions and other crops. In New York it is an annual threat to the commercial onion industry where populations are managed with regular applications of insecticides. Two peaks of flight activity occurred during the period when T. tabaci infest onions in New York. These flights were composed of both female and males of this species, as well as a smaller number of other species. On-plant populations consisted of both female and male T. tabaci but no other species of thrips. Numbers of thrips on onion plants increased steadily through the growing season, exceeding the economic threshold of three thrips per leaf by mid to late summer in most fields. During the period of population increase, and especially during peaks of flight activity, airborne thrips were captured in equal numbers on traps placed throughout onion fields. Peaks of flight activity and proportions of T. tabaci of all thrips captured in onions did not correspond with peaks, harvest or ratio of thrips captured in neighboring field and forage crops, although T. tabaci was found to be a dominant species in areas outside onion fields. Sexually reproducing strains of T. tabaci were collected from onion fields. These were found to be highly resistant to pyrethroids, including l -cyhalothrin. By contrast, T. tabaci collected in areas adjacent to onions, such as alfalfa fields, reproduced asexually and had low resistance to l -cyhalothrin. It was concluded that neighboring field and forage crops are not the most significant source of T. tabaci that invade onion fields each year and become hard to manage in New York. High levels of insecticide resistance indicate that a resistance management plan and the promotion of integrated pest management in New York's onion industry should be high priorities in the near future.

Book Synopsis Transmission Efficiency and Life Table Parameters of Western Flower Thrips, Frankliniella Occidentalis (Pergande) Exposed to Tomato Spotted Wilt Virus-impatiens Serotype by : Diane M. Sether

Sether and published by . This book was released on 1991 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Peppermint, Mentha piperita 'Black Mitcham' was established as a host for tomato spotted wilt virus-impatiens serotype (TSWV-I). TSWV-I infection of peppermint, initially observed in a research greenhouse (Corvallis, OR), included stunting and downward curling of leaves accompanied by bronzing, and occasionally tip necrosis. Young leaves appeared either symptomless, deformed, or pale even under high nitrogen conditions. Older leaves had sunken, brownish-grey lesions. Bright yellow mottling was observed on newly mature deep green leaves. A begonia isolate of TSWV-I was transmitted to peppermint both mechanically and by western flower thrips, Frankliniella occidentalis (Pergande). Symptoms of TSWV-I infection were similar although only a faint yellow mottling was produced and only under cool temperatures (15°C). ELISA detection of virus distribution throughout the plant indicated infection was systemic. Bulked groups of thrips (5 thrips/sample) also tested positive for TSWV-I using ELISA. Transmission efficiency of 4, 6, 8, and 10 day old thrips adults given acquisition sources during the entire nymphal stage varied from 0-40% for thrips tested in pairs and 0-20% for single thrips (based on a 12 hour access feeding period). Adults 2 days old failed to transmit the virus. Western flower thrips exposed to TSWV-I had reduced survival and reproductive potential and slower development rates than unexposed thrips. Virusexposed thrips were 1.4 times as likely to die than unexposed thrips on a given day. Both individual and population reproductive potentials were significantly lower. Preoviposition period was extended in virus-exposed thrips. Development time from second instar to adult was 15% longer for virus-exposed thrips. This is the first report of altered population parameters in western flower thrips exposed to TSWV-I.

Book Synopsis Sustainable Management of Arthropod Pests of Tomato by : Waqas Wakil
Download or read book Sustainable Management of Arthropod Pests of Tomato written by Waqas Wakil and published by Academic Press. This book was released on 2017-11-19 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainable Management of Arthropod Pests of Tomato provides insight into the proper and appropriate application of pesticides and the integration of alternative pest management methods. The basis of good crop management decisions is a better understanding of the crop ecosystem, including the pests, their natural enemies, and the crop itself. This book provides a global overview of the biology and management of key arthropod pests of tomatoes, including arthropod-vectored diseases. It includes information that places tomatoes in terms of global food production and food security, with each pest chapter including the predators and parasitoids that have specifically been found to have the greatest impact on reducing that particular pest. In-depth coverage of the development of resistance in tomato plants and the biotic and abiotic elicitors of resistance and detailed information about the sustainable management of tomato pests is also presented. Provides basic biological and management information for arthropod pests of tomato from a global perspective, encompassing all production types (field, protected, organic) Includes chapters on integrated management of tomato pests and specific aspects of tomato pest management, including within protected structures and in organic production Presents management systems that have been tested in the real-world by the authors of each chapter Fully illustrated throughout with line drawings and color plates that illustrate key pest and beneficial arthropods associated with tomato production around the world
Download or read book The Potato Crop written by Hugo Campos and published by Springer Nature. This book was released on 2019-12-03 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is open access under a CC BY 4.0 license. This book provides a fresh, updated and science-based perspective on the current status and prospects of the diverse array of topics related to the potato, and was written by distinguished scientists with hands-on global experience in research aspects related to potato. The potato is the third most important global food crop in terms of consumption. Being the only vegetatively propagated species among the world’s main five staple crops creates both issues and opportunities for the potato: on the one hand, this constrains the speed of its geographic expansion and its options for international commercialization and distribution when compared with commodity crops such as maize, wheat or rice. On the other, it provides an effective insulation against speculation and unforeseen spikes in commodity prices, since the potato does not represent a good traded on global markets. These two factors highlight the underappreciated and underrated role of the potato as a dependable nutrition security crop, one that can mitigate turmoil in world food supply and demand and political instability in some developing countries. Increasingly, the global role of the potato has expanded from a profitable crop in developing countries to a crop providing income and nutrition security in developing ones. This book will appeal to academics and students of crop sciences, but also policy makers and other stakeholders involved in the potato and its contribution to humankind’s food security.
