“…The negative effect of kaolin clay treatments on T. tabaci was conÞrmed in a Þeld trial, where it decreased the abundance of thrips adults and larvae at peak population times (Larentzaki et al 2008). However, what seemed to be a promising tool against T. tabaci in onion did not work in cabbage.…”

Onion thrips (Thrips tabaci Lindeman) has become a signiÞcant pest of cabbage (Brasssica oleracea L.) in regions with a dry continental climate. Thrips-resistant cabbage varieties have been developed in breeding programs, but the mechanisms of resistance remain largely unknown. Antixenosis, one of the three resistance mechanisms, may play a role but no plant trait has been identiÞed as a source of antixenosis. A series of studies were conducted to identify resistance mechanisms in this insectÐ crop interaction and to seek plant traits that were correlated to resistance. In this Þrst article of the series, the result of studying antixenosis and overall resistance of cabbage and the correlation between antixenosis and light reßectance characteristics are reported. There were distinct differences in the overall resistance to thrips between the six cabbage varieties studied. There were more pronounced differences between varieties based on the number of damaged head leaves compared with the use of damage ratings as a measure of overall resistance. Varieties also differed in their level of antixenosis; proportional abundance of thrips adults on head-forming leaves was more closely correlated to overall resistance of cabbage than actual thrips numbers. Some of the variables computed from the recorded reßectance spectra of cabbage were correlated to thrips abundance on head-forming leaves only in the Þrst but not in the second year of this study, suggesting that either spectral characteristics do not affect antixenosis or other variables may affect thripsÕ responses to spectral cues. Furthermore, multiple spray applications of a kaolin particle-based product signiÞcantly changed the light reßectance characteristics of cabbage, but it did not reduce the actual thrips abundance on head-forming leaves.

“…Larentzaki et al (2008a) studied the effect of kaolin particle Þlm on T. tabaci in onion and found that it had signiÞcant negative effects on oviposition, feeding and development of T. tabaci under laboratory conditions and thrips populations were signiÞcantly lower on kaolin-treated plots in Þeld conditions. Lu (1990) observed that silver mulches more effectively repelled T. tabaci when shallots, Allium cepa var.…”

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.)...

“…Their application method visibly does not provide a full and continuous coverage of plant material with kaolin particle film. Therefore, failure of kaolin to control aphids in their study may be attributable to the application method they have used, since better application methods and frequent treatments are required to cover newly expanding foliage [14].…”

Abstract:Infestations of the aphid Lipaphis erysimi Kalt.cause a mean yield loss of cabbage that varies from 35.4% to 73.3% depending from agro-climatic conditions. To control this pest insect in Sub-saharan Africa, synthetic chemical insecticides are usually applied. Kaolin is a white, non-abrasive, inert aluminosilicate mineral that has been shown to effectively protect host plants from insect pests including lepidopterans, sucking insects and mites. The present work is aimed to study the effects of kaolin on the population dynamics of L. erysimi for the Integrated Management of this insect pest in cabbage. To carry out the present study, kaolin powder was dissolved in water to obtain a concentration of 5% kaolin. The plants were sprayed with kaolin suspension every week and every 4-days in 2 respective experiments. Results showed that kaolin sprays significantly reduced aphid populations density. Nevertheless, more frequent applications (every 4 days) did not improve kaolin efficacy. It is concluded that kaolin technology should be combined with another plant protection measure in order to keep aphids population under control in cabbage.
