During the past two decades, onion thrips, Thrips tabaci Lindeman (Thysanoptera: Thripidae), has become a global pest of increasing concern in commercial onion (Allium cepa L.), because of its development of resistance to insecticides, ability to transmit plant pathogens, and frequency of producing more generations at high temperatures. T. tabaci feeds directly on leaves, causing blotches and premature senescence as well as distorted and undersized bulbs. T. tabaci can cause yield loss Ͼ50% but can be even more problematic when it transmits Iris yellow spot virus (family Bunyaviridae, genus Tospovirus, IYSV). IYSV was identiÞed in 1981 in Brazil and has spread to many important onion-producing regions of the world, including several U.S. states. IYSV symptoms include straw-colored, dry, tan, spindle-or diamond-shaped lesions on the leaves and scapes of onion plants and can cause yield loss up to 100%. Here, we review the biology and ecology of T. tabaci and discuss current management strategies based on chemical, biological, and cultural control as well as host resistance. Future directions for research in integrated pest management are examined and discussed.RESUMEN En las ultimas dos dé cadas, el trips de la cebolla, Thrips tabaci Lindeman (Thysanoptera: Thripidae), se ha convertido en una plaga mundial de alto interé s en cebolla, Allium cepa L., debido a su desarrollo de resistencia a insecticidas, capacidad para transmitir pató genos en plantas, y producció n de mayor numero de generaciones a altas temperaturas. T. tabaci se alimenta directamente sobre las hojas causando manchas, senescencia prematura, asṍ como bulbos pequeñ os y desformados. T. tabaci puede causar perdidas en rendimiento mayores al 50%, pero esta plaga puede ser aun más problemática cuando transmite Iris yellow spot virus (family Bunyaviridae, genus Tospovirus, IYSV). IYSV fue identiÞcado en Brasil en 1981 y desde entonces se ha propagado a importantes regiones productoras de cebolla a nivel mundial, incluyendo diferentes estados en los Estados Unidos. Los sṍntomas del IYSV incluye lesiones secas en forma angular o de diamante, de color café claro en las hojas y tallos de la cebolla y puede producir hasta 100% de perdidas en rendimiento. En este articulo nosotros revisamos la biologṍa y ecologṍa de T. tabaci y presentamos los actuales mé todos de manejo basados en control quṍmico, bioló gico y cultural asṍ como el mé todo de resistencia de plantas a insectos. Las direcciones futuras para investigació n en manejo integrado de esta plaga son analizadas. KEY WORDS Thrips tabaci, Allium cepa, Iris yellow spot virus, managementOnion thrips, Thrips tabaci Lindeman (Thysanoptera: Thripidae), has been the subject of considerable research and extension publications since it was Þrst described in 1888 (Lindeman 1889). Some aspects of its biology, ecology, and management have been summarized in T. LewisÕ highly regarded 1997 book, Thrips as Crop Pests, but a considerable amount of detail important for its management on onion (Allium cepa L.)...

“…For instance, Bt rice has been field tested extensively in China and other countries (Huang et al 2005, Cohen et al 2008. Different Bt vegetables-including eggplant, cauliflower, and cabbage-are likely to be commercialized soon in India and other countries in Asia and Africa (Krishna & Qaim 2007, Shelton et al 2008. HT rice is also in a relatively advanced phase within the research and development (R&D) pipeline (Hareau et al 2006).…”

Genetically modified (GM) crops have been used commercially for more than 10 years. Available impact studies of insect-resistant and herbicide-tolerant crops show that these technologies are beneficial to farmers and consumers, producing large aggregate welfare gains as well as positive effects for the environment and human health. The advantages of future applications could even be much bigger. Given a conducive institutional framework, GM crops can contribute significantly to global food security and poverty reduction. Nonetheless, widespread public reservations have led to a complex system of regulations. Overregulation has become a real threat for the further development and use of GM crops. The costs in terms of foregone benefits may be large, especially for developing countries. Economics research has an important role to play in designing efficient regulatory mechanisms and agricultural innovation systems.
