Download or read book Onions and Other Vegetable Alliums written by James L. Brewster and published by CABI. This book was released on 2008 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: This fully revised, expanded and updated edition of the successful text, Onions and Other Vegetable Alliums, relates the production and utilization of these familiar and important vegetable crops to the many aspects of plant science underpinning their production and storage technologies. Chapters cover species and crop types, plant structure, genetics and breeding, physiology of growth and development as well as pests and diseases, production agronomy, storage after harvest and the biochemistry of flavour, storage carbohydrates and colour and how this relates to nutritional and health benefits. From this wide perspective it is possible to see many examples where underlying scientific knowledge illuminates, explains and can improve agronomic practice. The reader will get an insight into how molecular methods are revolutionizing the study of taxonomy, genetics, pathology and physiology and how these methods are being applied in the breeding of improved crops.

This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Early season thrips damage to cotton can reduce yield and kill plant terminals. Control measures and the compounds used to control thrips vary widely. Thrips species, such as onion thrips, Thrips tabaci Lindman and western flower thrips, Frankliniella occidentalis (Pergande), are major contributors to the agricultural crop pest spectrum on numerous crops. The persistence of these two species as crop pests has led to the delineation of species-specific tactics for insecticidal control measures. The primary objective of this research was to characterize and compare attributes of five insecticides in different classes: anthranilic diamide (352-DPX), microcyclic lactone (spinosad, Tracer® 4 SC), neonicotinoid (thiomethoxam, Cruiser® 40 WG), carbamate (oxamyl, Vydate® L) and organophosphate (acephate, Orthene® 90 S) with thrips activity. Insecticidal potency, feeding/oviposition preference, reproductive effects and feeding damage were studied on T. tabaci and F. occidentalis . Adult potency data (LC50 or dose response mortality of each compound) showed that all compounds were more potent on T. tabaci than F. occidentalis . 352-DPX was 3823X less potent on F. occidentalis, followed by Orthene (411X), Vydate L (11X), and Tracer and Centric both with 6X lower potency on F. occidentalis . Results from the feeding and oviposition preference and reproductive effects bioassay indicated that adult T. tabaci and F. occidentalis tended to be equally distributed between treated and untreated leaves. Some exceptions are discussed where significantly more adults thrips were found on the untreated than treated leaves. The feeding and oviposition preference results indicate that in spite of the significantly lower potency on F. occidentalis, leaves treated with all compounds were less preferred over untreated leaves for feeding and oviposition, resulting in significantly lower larvae and feeding damage. Interestingly, only 352-DPX, Tracer and Vydate had this same effect on T. tabaci . Additional results indicate that sublethal concentrations (e.g. LC10 and LC50) had an effect on feeding and progeny reduction. Finally, treated leaves resulted in lower percent plant damage, caused feeding cessation, and subsequently influenced larval populations. An improved population assessment for thrips management and plant protection was developed based on these findings.

Available in PDF, EPUB and Kindle. Book excerpt: Thrips (fhysanoptera) are very small insects, widespread throughout the world with a preponderance of tropical species, many temperate ones, and even a few living in arctic regions. Of the approximately 5,000 species so far identified, only a few hundred are crop pests, causing serious damage or transmitting diseases to growing crops and harvestable produce in most countries. Their fringed wings confer a natural ability to disperse widely, blown by the wind. Their minute size and cryptic behavior make them difficult to detect either in the field or in fresh vegetation transported during international trade of vegetables, fruit and ornamental flowers. Many species have now spread from their original natural habitats and hosts to favorable new environments where they often reproduce rapidly to develop intense damaging infestations that are costly to control. Over the past decade there have been several spectacular examples of this. The western flower thrips has expanded its range from the North American continent to Europe, Australia and South Africa. Thrips palmi has spread from its presumed origin, the island of Sumatra, to the coast of Florida, and threatens to extend its distribution throughout North and South America. Pear thrips, a known orchard pest of Europe and the western United States and Canada has recently become a major defoliator of hardwood trees in Vermont and the neighboring states. Local outbreaks of other species are also becoming problems in field and glasshouse crops as the effectiveness of insecticides against them decline.

Download or read book Population Dynamics and Insecticide Resistance of Onion Thrips, Thrips Tabaci Lindeman (Thysanoptera: Thripidae) in Onions written by Jody Lynn Gangloff and published by . 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.
