Citrus thrips, Scirtothrips citri (Moulton), is a plant-feeding pest most widely recognized for damage caused to citrus and mango fruits. Citrus thrips have also become a significant pest in California's blueberries. Avocado thrips, Scirtothrips perseae Nakahara, is a pest of avocados (Persea americana Mill. [Lauraceae]) in California. Pesticides are often used to manage these two species of thrips and therefore, the likelihood of resistance development is high. There is increasing pressure in the United States to move away from broad-spectrum insecticides and focus on alternative methods of control, e.g., genetically modified crop plants expressing Bt (Bacillus thuringiensis) toxins, use of biorational insecticides such as toxic Bt protein sprays and entomopathogens (such as various strains of Beauveria bassiana Balsamo, and other agents). Integrated pest management programs are essential for any agricultural commodity. The goal of the work described here is to add to the foundation of knowledge to improve the integrated pest management of citrus thrips and avocado thrips. The research conducted for this disseration (1) examined alternatives to traditional insecticides (Bt protein sprays and several strains of B. bassiana) to control both avocado and citrus thrips in the laboratory and resulted in no efficacy of the Bts tested but one strain of fungus, the commercially available strain was able to infect citrus thrips at field obtainable levels, (2) tested the commercially available strain in different formulations and water regimes against citrus thrips in blueberry fields which resulted in some control but not enough to strongly recommend this as an alternative to traditional pesticides, (3) evaluated the impact of some of the insecticides registered for avocado thrips management on the beneficial native predaceous mite Euseius hibisci Chant in avocado orchards and found that each of the pesticides harmed the mite but at varying levels and durations, (4) assessed citrus thrips oviposition on blueberry varieties with choice and no-choice tests and it was determined that citrus thrips likely oviposit to differing degrees in some plants over others, and finally (5) determined that citrus thrips in the Americas was actually a complex of species that were nearly morphologically identical but molecularly quite distinct.

Download The Future Role of Pesticides in US Agriculture Book in PDF, ePub and Kindle
Although chemical pesticides safeguard crops and improve farm productivity, they are increasingly feared for their potentially dangerous residues and their effects on ecosystems. The Future Role of Pesticides explores the role of chemical pesticides in the decade ahead and identifies the most promising opportunities for increasing the benefits and reducing the risks of pesticide use. The committee recommends R&D, program, and policy initiatives for federal agriculture authorities and other stakeholders in the public and private sectors. This book presents clear overviews of key factors in chemical pesticide use, including: Advances in genetic engineering not only of pest-resistant crops but also of pests themselves. Problems in pesticide useâ€"concerns about the health of agricultural workers, the ability of pests to develop resistance, issues of public perception, and more. Impending shifts in agricultureâ€"globalization of the economy, biological "invasions" of organisms, rising sensitivity toward cross-border environmental issues, and other trends. With a model and working examples, this book offers guidance on how to assess various pest control strategies available to today's agriculturist.
