Available in PDF, EPUB and Kindle. Book excerpt: The Central Valley produces the majority of California almonds. Navel Orangeworm, Anyelois Transitella (Walker), is the most critical pest of almonds in California. Management of Navel Orangeworm is primarily accomplished by cultural practices of mummy shaking and early harvest. Research on management practices that control Navel Orangeworm have been limited by the number of studies, replicates within the studies, the scope of the replicates and examined factors of control. This study looked at the effectiveness of multiple farm management practices on Navel Orangeworm, using egg counts as an indicator of pest population pressure. Sixty farms (11 organic, 49 conventional) were monitored from May 1st to October 5th in 2012. Egg counts were then analyzed by farm type, distance from organic farms, direction to organic farms, management practices and multiple environmental factors. This study found that there was no difference in egg counts between farm types, egg count differences were not correlated with the trapping distance, and nine management practices and environmental factors were identified as significant drivers of orchard egg counts. There were significant differences between farms as the number of chemical applications increased, and there was no significant difference in the percent of inedible nuts between organic and conventional farms. This study revealed that farmers who sprayed less for Navel Orangeworm, used less potent pesticides, did not use miticides and fungicides and mowed or disked their mummy nuts tended to have lower egg counts within their orchards.

Available in PDF, EPUB and Kindle. Book excerpt: A three-step, quasi-double-bind approach was used as a proof-of-concept study to screen twenty compounds for their ability to reduce oviposition of gravid female navel orangeworm (NOW), Ameylois transitella (Lepidoptera: Pyralidae). First, the panel of compounds, whose identity was unknown to the experimenters, was tested by electroantennogram (EAG) using antennae of two-day old gravid females as the sensing element. Of the twenty compounds tested three showed significant EAG responses. These three EAG-active compounds and a negative control were then analyzed for their ability to reduce oviposition via small-cage, two-choice laboratory assays. Two of the three compounds significantly reduced oviposition under laboratory conditions. Lastly, these two compounds were deployed in a field setting in an organic almond orchard in Arbuckle, CA using black egg traps to monitor NOW oviposition. One of these two compounds significantly reduced oviposition on black egg traps under these field conditions. Compound 9 (later identified as isophorone) showed a significant reduction in oviposition in field assays and thus has a potential as a tool to control the navel orangeworm as a pest of almonds.

Available in PDF, EPUB and Kindle. Book excerpt: The sterile insect technique (SIT) is an environment-friendly method of pest control that integrates well into area-wide integrated pest management (AW-IPM) programmes. This book takes a generic, thematic, comprehensive, and global approach in describing the principles and practice of the SIT. The strengths and weaknesses, and successes and failures, of the SIT are evaluated openly and fairly from a scientific perspective. The SIT is applicable to some major pests of plant-, animal-, and human-health importance, and criteria are provided to guide in the selection of pests appropriate for the SIT. In the second edition, all aspects of the SIT have been updated and the content considerably expanded. A great variety of subjects is covered, from the history of the SIT to improved prospects for its future application. The major chapters discuss the principles and technical components of applying sterile insects. The four main strategic options in using the SIT — suppression, containment, prevention, and eradication — with examples of each option are described in detail. Other chapters deal with supportive technologies, economic, environmental, and management considerations, and the socio-economic impact of AW-IPM programmes that integrate the SIT. In addition, this second edition includes six new chapters covering the latest developments in the technology: managing pathogens in insect mass-rearing, using symbionts and modern molecular technologies in support of the SIT, applying post-factory nutritional, hormonal, and semiochemical treatments, applying the SIT to eradicate outbreaks of invasive pests, and using the SIT against mosquito vectors of disease. This book will be useful reading for students in animal-, human-, and plant-health courses. The in-depth reviews of all aspects of the SIT and its integration into AW-IPM programmes, complete with extensive lists of scientific references, will be of great value to researchers, teachers, animal-, human-, and plant-health practitioners, and policy makers.

This book was released on 2008-10-08 with total page 654 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tree species are indispensable to support human life. Due to their long life cycle and environmental sensitivity, breeding trees to suit day-to-day human needs is a formidable challenge. Whether they are edible or industrial crops, improving yield under optimal, sub-optimal and marginal areas calls for uni?ed efforts from the s- entistsaroundtheworld. Whiletheuniquenessofcoconutaskalpavriksha(Sanskr- meaning tree-of-life) marks its presence in every continent from Far East to South America, tree crops like cocoa, oil palm, rubber, apple, peach, grapes and walnut prove their environmental sensitivity towards tropical, sub-tropical and temperate climates. Desert climate is quintessential for date palm. Thus, from soft drinks to breweries to beverages to oil to tyres, the value addition offers a spectrum of pr- ucts to human kind, enriched with nutritional, environmental, ?nancial, social and trade related attributes. Taxonomically, tree crops do not con?ne to a few families, but spread across a section of genera, an attribute so unique that contributes immensely to genetic biodiversity even while cultivated at the commercial scale. Many of these species in?uence other ?ora to nurture in their vicinity, thus ensuring their integrity in p- serving the genetic biodiversity.
