“…In research conducted from 2001 to 2002 in Canada, MacIntyre-Allen et al (2005a) studied the sex ratio of T. tabaci in onion Þelds by using water pan and sticky traps and found that 100% of the T. tabaci captured were females. In addition, T. tabaci populations collected from the Þeld in 2000 and reared in laboratory conditions until 2004 did not produce males.…”

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.

“…The majority of users apply sticky traps without knowledge of monitoring validity for actual pest or beneficial densities on crops. Nevertheless, meaningful correlations of trapped insects with population densities in the crop were described already for thrips, whiteflies and parasitoids (Gerling and Horowitz 1984;Macintyre-Allen et al 2005;B€ ockmann et al 2014). But there are also examples with parasitoids and whiteflies, where no such correlation could be recognized so far (Karut and Kazak 2007;Hoelmer and Simmons 2008) or where correlation was only valid in the close proximity of traps (Gillespie and Quiring 1987).…”

Sticky trap monitoring of a pest–predator system in glasshouse tomato crops: are available trap colours sufficient?

Monitoring of pest presence and population development in the crop during the season is essential for integrated pest management. Although many tools, for instance coloured sticky traps, have been developed, the full advantage of available information is rarely taken into account in decision‐making. The reasons behind include high workload in practice but also the poorly studied relationships between trap catches and populations in the crop. Here, we investigate whether commercially available coloured sticky traps can be used as tool to monitor population densities of a pest–predator system in glasshouse tomato. The response of Macrolophus pygmaeus (Rambur) (Hemiptera, Miridae) to blue and yellow sticky traps was tested in laboratory and glasshouse experiments. The results indicate that M. pygmaeus can be monitored equally well with both trap colours. The number of trapped insects showed good correlation with the population densities on the crop. Under growing conditions, more M. pygmaeus were trapped on blue compared with yellow sticky traps. However, due to the known preference of Trialeurodes vaporariorum (Westwood) (Hemiptera, Aleyrodidae), yellow traps should be used for a combined pest–predator monitoring.

“…Various kinds of trap without chemical attractants have also been tested, and several studies have reported the effects of trap attributes such as type, colour, orientation and size on attraction and capture of thrips . Thrips monitoring and ecology studies have commonly been carried out using water or sticky panel traps of various colours as the attractant, and NZFT have been shown to be most attracted to white and yellow water traps in the field when compared with green, blue and red . However, ethyl nicotinate has been shown to be significantly more attractive to NZFT than coloured traps, host fruit and other compounds such as cis ‐jasmone, ethyl isonicotinate and benzaldehyde .…”

Delta traps containing 6-pentyl-2H-pyran-2-one in a polyethylene bag at 2 m above the ground is the recommended method for monitoring NZFT, significantly improving the sensitivity, accuracy and labour input compared with prior methods. Long-term monitoring of NZFT could lead to more accurate economic damage thresholds and timing for when to apply insecticides. © 2014 Society of Chemical Industry.
