“…Previous studies have speculated that the photoreceptor types of thrips adults may include green, blue, and ultraviolet photoreceptors [17] , showing that these light spectra are recognized by insects, and can induce an optic nerve reaction, and may cause a phototactic response [18,19] . In this study, we found that under 120 lx, the spectral lights used in Experiment 1 all induced western flower thrips to show a selective visual response, and the response to blue light was the best, followed by UV, and green light ( Table 3), indicating that only under the appropriate illumination, does the optic nerve sensitivity spectrum result in a better selective response.…”

To understand how spectral light wavelength affects thrips visual sensitivity, the selective response and the approach sensitivity of western flower thrips were examined. The results showed that light intensity affected thrips selective sensitivity to different spectra, with good visual sensitivity to blue, ultraviolet (UV), and green light changes to UV, violet, and yellow light when illumination increased from 120 lx to 6000 lx. Red light was the sensitive spectral light driving thrips to respond to sensitive light. Under illumination, the best sensitivity response to spectra was violet, while under light energy, this changed to UV when light energy was increased to 120 mW/cm 2. However, the photo-stimulus properties (illumination or light energy) did not affect the optimal approach sensitivity to UV light. Furthermore, when illumination or light energy stimulated thrips to select two different spectral lights, the total response sensitivity to 12000 lx of UV and violet light were the best (83.27%), while at 60 mW/cm 2 of UV and yellow light was the best (82.15%). But different photo-stimulus properties influenced on the total approach sensitivity to the stimulation of two different spectral lights when the intensity of light increased, showing that to 12000 lx of violet and green light was the best (53.18%), while for 120 mW/cm 2 of UV and green light was the best (47.74%). The thrips visual selection response effects stimulated by illumination were different from that induced by light energy, and originated from the thrips different bio-regulatory effects caused by the intensity of light energy of illumination and the intensity of illumination of light energy. Therefore, different photo-stimulus effects can manipulate thrips visual sensitivity to enhance the phototactic effect.

“…Several studies in F. occidentalis demonstrate that increasing reflectance or a higher intensity of attractive colours like blue, yellow and white (−UV) increases attraction as determined by catch numbers, while increased intensity of other colours like green and white (+UV) do not change attraction levels [65,76–79,84] (electronic supplementary material, table S1). Red stimuli require intensities 100 times higher than yellow or blue to elicit positive phototaxis for F. occidentalis and T. palmi [48,66]. Furthermore, the response of thrips seems to reach a plateau at certain intensities, and the increase in attraction is not the same across the light spectrum, reinforcing the importance of colour composition [9,48,50,66].…”

“…Furthermore, the experiments are often biased towards a focus on blue and yellow stimuli, which have been heavily favoured historically and commercially as the attractant in trap design. Experiments that accurately test a wide spectrum of colour cues including UV are limited, though more recent efforts have improved in this regard due to the wide availability of spectrally flexible and narrow-wavelength light-emitting diodes (LEDs) [48][49][50]65,66].…”

Insects are an astonishingly successful and diverse group, occupying the gamut of habitats and lifestyle niches. They represent the vast majority of described species and total terrestrial animal biomass on the planet. Their success is in part owed to their sophisticated visual systems, including colour vision, which drive a variety of complex behaviours. However, the majority of research on insect vision has focused on only a few model organisms including flies, honeybees and butterflies. Especially understudied are phytophagous insects, such as diminutive thrips (Thysanoptera), in spite of their damage to agriculture. Thrips display robust yet variable colour-specific responses despite their miniaturized eyes, but little is known about the physiological and ecological basis of their visual systems. Here, we review the known visual behavioural information about thrips and the few physiological studies regarding their eyes. Eye structure, spectral sensitivity, opsin genes and the presence of putative colour filters in certain ommatidia strongly imply dynamic visual capabilities. Finally, we discuss the major gaps in knowledge that remain for a better understanding of the visual system of thrips and why bridging these gaps is important for expanding new possibilities for applied pest management strategies for these tiny insects. This article is part of the theme issue ‘Understanding colour vision: molecular, physiological, neuronal and behavioural studies in arthropods’.

“…Light intensity has a positive correlation with light wavelength. Increasing light intensity at each light wavelength will increase insect attraction to light (Murata et al, 2018). Therefore, this study aimed to investigate the attraction of S. incertulas to various LED colors.…”

The yellow rice stem borer (Scirpophaga incertulas Walker) is a major pests on rice. Light traps have been used for monitoring and controlling S. incertulas with white and ultraviolet color light sources. The purpose of this research was to invent trap which uses an effective color that attracts S. incertulas. This research begins by sampling female S. incertulas pre-oviposition from the field then tested in the laboratory. The experiment was designed with factorial randomized block design with light colors and light intencity as factors. Light-emitting diodes used in this research, consisted of normal red, normal yellow, normal green, superbright red, superbright yellow, superbright green, superbright blue, UV, and white. LED white, UV, and superbright blue were attractive colors to S. incertulas when exposure time was 15 minutes. Effective light intencity to attract S. incertulas was 1000 lux.
