This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The citrus leafminer (CLM), Phyllocnistis citrella Stainton (Lepidoptera: Gracillariidae) is an invasive herbivorous insect. CLM damage results in decreased sales of horticultural production for garden centers and homeowners. Nursery citrus growers in California treat for CLM several times per season primarily with the insecticide imidacloprid. The limitations and high cost of chemical control, in addition to toxicological problems such as insecticide persistence and resistance, justify the adoption of alternative management tactics. One non-chemical option for insect pest management is entomopathogenic nematodes (EPNs). Recent studies have shown greater EPN efficacy when applied with Barricade® gel, a fire retardant gel. Barricade® temporarily maintains moisture on the leaf surface, facilitating nematode survival. We sought to determine if UV protectants added to the Barricade® gel increase the efficacy of EPNs, to quantify the retention and survival of EPNs applied with gel, and to assess whether the gel facilitated nematode movement on an exposed surface The addition of UV protectants to the gel enhanced the protective properties of the formulation. Furthermore, we conclude that low concentration gel solution extends IJ survival up to 8 hours. Bottom-up methods of insect population management focus on modifying the host plant, often by strengthening plant defenses through nutrient management. Preliminary studies by our lab found a reduction in CLM feeding damage following treatment with soluble silicon. To expand on these results we sought to determine CLM oviposition preference, host acceptance, and preference for host volatiles. CLM adults were given a choice between a soluble silicon treated plant and a control. Adults were allowed to oviposit, then citrus leaves were inspected for eggs. CLM adults were also offered a dual choice in a glass Y-tube olfactometer. CLM adult females laid significantly fewer eggs on plants treated with soluble silicon. The evidence strongly suggests a silicate-induced change in the tactile or chemical profile of the leaf occurred. We also aimed to examine whether soluble silicate fertilizer could affect CLM population growth. To that end we sought to determine CLM larval feeding performance, quantify differences in rate of development and mortality of the larvae and pupae. The development of CLM from larvae to adult was observed and compared on soluble silicon fertilized plants vs. controls. We calculated net replacement rate (R[subscript]0) of CLM. CLM on soluble silicon fertilized plants had significantly lower survivorship than CLM on controls. The lower survivorship of CLM on soluble silicon plants suggests the possibility of induced plant defensive chemicals in the plants. The lower R[subscript]0 of the treated group is a strong indication that CLM population growth is reduced under the fertilizer regime. Our results show that the enhanced survival and mobility provided by the anti-desiccant and anti-UV materials have the potential to make EPNs more efficient at targeting foliar pests. Thorough testing of the combined results of soluble silicon and EPNs on CLM populations will determine the utility of these techniques in integrated pest management programs for CLM.

This book was released on 1997 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new pest has started to threaten the citrus industry in Lebanon, since summer 1994. This pest is the citrus leafminer. Pkyllocnistis citrella Stainton. The objective of" this study was to manage the citrus leafminer infestation by the use of biorational insecticides and compare their effect to other synthetic chemicals. The research work was divided into two parts: field experiments and laboratory experiments. In the field experiments, four different orchards were allocated in the South of Lebanon during summer 1995. In each orchard, only 50% of the trees received ammonium sulfate fertilizer. The insecticide treatments included the following: Paraffinic oil. abamectin. azadirachtin. Bacillus thuringiensi.s var. kurstaki, imidacloprid and cyromazine. The first insecticide application was during July 1995. Only two of the orchards received a second spray at the end of August due to the delay in summer flush in the other two locations. Sampling was done at six different dates including two initial sampling counts and four other samplings 10 and 20 days after each spray. Infestation was assessed by counting the number of eggs, live larvae and pupae per leaf. The same chemicals were tested against the last larval instar and the pupa in the laboratory, under controlled conditions. In the field experiments, both paraffinic oil and imidacloprid significantly decreased the number of live larvae per leaf compared to the control. Azadirachtin didn't result in an average low number oflarvae per leaf significantly different from control: but it was comparable to abamectin in its effect. However. B.t. didn't affect the citrus leafminer larvae. None of the tested chemicals had an effect on the eggs. Laboratory bioassays emphasized the effect of imidacloprid and abamectin in increasing the larval mortality. However, the paraffinic oil didn't succeed in causing a comparable high larval mortality. Therefore, oil can be considered a protective insecticide that hinders the insect from attacking the new flush. Fertilizer application has tended to increase the infestation level in most instances. Therefore, an integrated pest management program could be developed where oil could be a useful alternative to broad spectrum insecticides and where summer fertilization would be reduced to a minimum.

Download or read book Soil Organic Matter in Sustainable Agriculture written by Fred Magdoff and published by CRC Press. This book was released on 2004-05-27 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recognition of the importance of soil organic matter (SOM) in soil health and quality is a major part of fostering a holistic, preventive approach to agricultural management. Students in agronomy, horticulture, and soil science need a textbook that emphasizes strategies for using SOM management in the prevention of chemical, biological, and physical problems. Soil Organic Matter in Sustainable Agriculture gathers key scientific reviews concerning issues that are critical for successful SOM management. This textbook contains evaluations of the types of organic soil constituents—organisms, fresh residues, and well-decomposed substances. It explores the beneficial effects of organic matter on soil and the various practices that enhance SOM. Chapters include an examination of the results of crop management practices on soil organisms, organic matter gains and losses, the significance of various SOM fractions, and the contributions of fungi and earthworms to soil quality and crop growth. Emphasizing the prevention of imbalances that lead to soil and crop problems, the text also explores the development of soils suppressive to plant diseases and pests, and relates SOM management to the supply of nutrients to crops. This book provides the essential scientific background and poses the challenging questions that students need to better understand SOM and develop improved soil and crop management systems.
