“…This is especially true for pests that have developed resistance to most of the currently used pesticides. F. occidentalis is a serious greenhouse pest with a world-wide distribution and a high degree of pesticide resistance (Br0dsgaard, 1989a;Helyer & Brobyn, 1992). It is therefore important to develop optimal monitoring tools for this pest.…”

Sticky blue traps are a suitable and important tool for Western Flower Thrips population monitoring in greenhouses. They can be used in vegetables and in ornamentals, and provideimportant information on the current status of the pest population. However, such traps cannot be used in some susceptible plant species when they are flowering because at that stage the plants are more attractive to Western Flower Thrips than the traps. We therefore tried to increase trap attractiveness by combining the colour cue with an attractive odour cue. In laboratory experiments, we found a significant additive effect on attractiveness for two odours in traps provided with both the visual and the olfactory cues as compared to traps with either cue alone. However, these results could not easily be reproduced in greenhouses. The main factors responsible for this failure seem to be (1) the only moderate, additive increase of trap attractiveness when using combined visual and olfactory cues, and (2) the problems associated with odour diffusion. Unless a more attractive odour is found and a suitable odour dispenser is available, the use of odours to enhance sticky blue trap attractiveness for Western Flower Thrips cannot be recommended and, given the added cost for the trap, may not be affordable for growers.

“…Each test was replicated two to four times depending on the numbers of thrips available. Numbers tested always exceeded the 120 minimum individuals proposed by Robertson el Helyer and Brobyn (1992) used a similar method, but their process required separate treatments of leaf-discs and thrips. The thrips were immersed in insecticide emulsions, and the discs sprayed with a Potter spray tower before being set in agar.…”

“…Western flower thrips, Frankliniella occidentalis (Pergande), is a serious economic pest of horticultural crops in many countries (Nasruddin and Smitley 1991;Helyer and Brobyn 1992;Immaraju et al 1992) and has proved difficult to control because of its ability to develop insecticide resistance (Schreiber et al 1990;Immaraju et al 1992). F. occidentalis was first discovered in Australia (Western Australia) in April 1993 (Malipatil et al 1993), and was subsequently detected in New South Wales in September 1993 (P. Gillespie, pers.…”

Two field collected strains of western flower thrips, Frankliniella occidentalis, were tested against proprietary and experimental formulations of insecticide. Thrips were tested using a novel method whereby thrips were confined in testing units throughout all stages of the bioassay procedure. The bioassay technique proved to be quick and robust. Of the chemicals tested, the two non-registered compounds chlorfenopyr and fipronil were most active against field-collected F. occidentalis. The field-collected strains were tolerant to a range of organophosphate, carbamate and pyrethroid chemicals. Comparisons of dose-response curves with established field-use-rates indicate that only methiocarb and methamidophos are likely to be completely effective in the field. The theoretical implications of the data for management of F. occidentalis in Australia is discussed.

“…One of the factors that accelerates the infestations and makes thrips difficult to control is their dispersion and spatial distribution potential (Helyer & Brobyn, 1992). Understanding their spatial distribution may be one of the ways to improve chemical and biological controls, directing them toward areas of higher density and detecting the source of initial infestation (Carrillo et al, 2014).…”

-The objective of this work was to evaluate the spatial distribution of thrips in different crops, and the correlation between meterological parameters and the flight movements of this pest, using immunomarking. The experiment was conducted in cultivated areas, with tomato (Solanum lycopersicum), potato (Solanum tuberosum), and onion (Allium cepa); and non-cultivated areas, with weedy plants. The areas with tomato (100 days), potato (20 days), and weeds were sprayed with casein, albumin, and soy milk, respectively, to mark adult thrips; however, the areas with onion (50 days) and tomato (10 days) were not sprayed. Thrips were captured with georeferenced blue sticky traps, transferred into tubes, and identified by treatment area with the Elisa test. The dependence between the samples and the capture distance was determined using geostatistics. Meteorlogical parameters were correlated with thrips density in each area. The three protein types used for immunomarking were detected in different proportions in the thrips. There was a correlation between casein-marked thrips and wind speed. The thrips flew a maximum distance of 3.5 km and dispersed from the older (tomato) to the younger crops (potato). The immunomarking method is efficient to mark large quantities of thrips.Index terms: Alliaceae, dispersal pattern, Elisa, integrated pest management, Solanaceae, Thysanoptera. Movimento de voo e distribuição espacial de tripes imunomarcados em cebola, batata e tomateResumo -O objetivo deste trabalho foi avaliar a distribuição espacial de tripes em diferentes cultivos, e a correlação entre os parâmetros meteorológicos e o movimento de voo dessa praga, com uso de imunomarcação. O experimento foi conduzido em área cultivada com tomate (Solanum lycopersicum), batata (Solanum tuberosum) e cebola (Allium cepa); e não cultivada, com plantas daninhas. As áreas com tomate (100 dias), batata (20 dias) e plantas daninhas foram pulverizadas com caseína, albumina e leite de soja, respectivamente, para marcar os tripes adultos; no entanto, as áreas com cebola (50 dias) e tomate (10 dias) não foram pulverizadas. Os tripes foram capturados com armadilha adesiva de cor azul georeferenciada, acondicionados em tubos e identificados, por área de tratamento, com o teste de Elisa. Determinou-se a dependência entre as amostras e a distância de captura com uso de geoestatística. Os parâmetros meteorológicos foram correlacionados com a densidade de tripes em cada área. Os três tipos de proteína usados na imunomarcação foram detectados, em diferentes proporções, nos tripes. Houve correlação entre os tripes marcados com caseína e a velocidade do vento. Os tripes voaram uma distância máxima de 3,5 km e dispersaram dos cultivos mais velhos (tomate) para os mais jovens (batata). O método de imunomarcação é eficiente para marcar grandes quantidades de tripes.Termos para indexação: Alliaceae, padrão de dispersão, Elisa, manejo integrado de pragas, Solanaceae, Thysanoptera.
