“…Chemical control measures are the most widely known form of control of thrips in cowpea; however, the rapid development of insecticide resistance in thrips populations has rendered the chemical treatments ineffective (Morse and Hoddle, 2006). Furthermore, in cases where cowpea leaves and green pods are eaten fresh as a vegetable, insecticides pose a threat to the consumers,in addition to other hazardous effects to the environment (Oyewale and Bamaiyi, 2013).…”

“…Así mismo, en todos los tercios se producen tejidos en crecimiento (terminales y botones florales) lo que genera la misma oferta de alimento en cada uno de ellos para el insecto. Esto último concuerda con Morse & Hoddle (2006), quienes mencionan que el ataque de trips no se reduce a ciertas áreas, sino que se extiende a todas las áreas con tejido en crecimiento de la planta. Este comportamiento del insecto en la planta sugiere que el muestreo del trips puede hacerse tomando cualquier terminal en la planta, debido a que existe la misma probabilidad de encontrar el trips en cualquiera de estos, independientemente de su ubicación.…”

Resumen -El objetivo de este trabajo fue desarrollar una propuesta de muestreo de Neohydatothrips signifer en el cultivo de maracuyá. Se correlacionó la infestación promedio del trips en el cultivo con las variables meteorológicas de humedad relativa, temperatura y precipitación, con uso del coeficiente de correlación de Pearson. Así mismo, se determinó el índice de agregación de la población en el cultivo, con la prueba chi cuadrado (X 2 ) para la distribución de Poisson, la prueba de la razón V²/μ, y la distribución de la binomial negativa. La única variable climática que se correlacionó significativamente con la densidad promedio del trips fue la temperatura. Se presentó mayor incidencia y densidad poblacional del insecto en los terminales vegetativos en comparación con los botones florales. El patrón de disposición espacial que se presentó en todos los estados de desarrollo fenológico del cultivo fue de tipo agregado. Con el índice de agregación y el tamaño promedio de la población, se calculó que se deben muestrear 22 terminales nuevos por hectárea, sin importar su posición en la planta. El muestreo del trips en el cultivo de maracuyá debe hacerse sobre los terminales vegetativos de la planta, sin importar la posición del terminal en ella.Términos para indexación: Passiflora edulis f. flavicarpa, distribución espacial, fluctuación poblacional, índice de agregación, trips. Proposed sampling for Neohydatothrips signifer (Thysanoptera:Thripidae) in passion fruit cropAbstract -The objective of this work was to develop a proposal for Neohydatothrips signifer sampling in the passion fruit crop. Average thrip infestation on the crop was correlated with the meteorological variables of relative humidity, temperature, and precipitation using Pearson correlation coefficient. Likewise, determinations were done for the aggregation rate of the growing population using chi square (X 2 ) for the Poisson distribution, the ratio test V²/μ and the negative binomial distribution. Temperature is the only climatic variable that significantly correlated with the mean density of the thrips. There were higher incidence and population density of the insects at the vegetative terminal buds, in comparison to the flower buds. The spatial distribution pattern for this insect, along all phenological stages of the plant, was aggregated. Using the aggregation index and the average population, a sample of 22 new vegetative terminal buds per hectare was determined as appropriate, regardless of its position within the plant. A thrip sampling method in the passion fruit crop should sample over terminal buds, without account their position on plants.

“…A critical question regarding C. fasciatus is: why has it failed to establish outside of its home range? Bean thrips is common in California, polyphagous, and infests a variety of commodities that are exported; qualities that could easily predispose it to an invasive lifestyle (Morse & Hoddle 2006). Similarly, Thrips imaginis and T. obscuratus, native to Australia and New Fig.…”

“…This is particularly true for Thysanoptera, whose adults and larvae are very small, highly thigmotactic, and often lay minute eggs within plant material (e.g. petioles, stems, leaves and fruit) making rapid visual detection impossible (Mound 2005;Morse & Hoddle 2006).…”

Caliothrips fasciatus is native to the USA and western Mexico and overwintering adults are regular contaminants in the ‘navel’ of navel oranges exported from California, USA to Australia, New Zealand and elsewhere. Due to the long history of regular interceptions of C. fasciatus in Australia, a survey for this thrips was undertaken around airports, seaports, public recreational parks and major agricultural areas in the states of Queensland, New South Wales, Victoria, South Australia and Western Australia to determine whether C. fasciatus has successfully invaded Australia. Host plants that are known to support populations of C. fasciatus, such as various annual and perennial agricultural crops, urban ornamentals and weeds along with native Australian flora, were sampled for this thrips. A total of 4675 thrips specimens encompassing at least 76 species from a minimum of 47 genera, and three families were collected from at least 159 plant species in 67 families. Caliothrips striatopterus was collected in Queensland, but the target species, C. fasciatus, was not found anywhere. An undescribed genus of Thripidae, Panchaetothripinae, was collected from ornamental Grevillea (var. Robyn Gordon) at Perth (Western Australia) Domestic Airport, and is considered to be a native Australian species. This survey has provided valuable information on the background diversity of thrips species associated with various native and exotic plant species around major ports of entry and exit for four of five states in Australia. We suggest that the major reason C. fasciatus has not established in Australia is due to high adult mortality in navels that are kept at low storage temperatures (2.78°C) during an 18‐ to 24‐day transit period from California to Australia.
