“…These results may indicate that thrips are maximally sensitive in the UV-B and short UV-A spectral region (between 290 and 330 nm) or that they are particularly attracted by these wavelengths under confinement conditions. Independent of the interpretation, the action spectrum demonstrates that (i) C. phaseoli is highly sensitive to wavelengths as short as 290 nm, and, (ii) in contrast with the observations in flower thrips (Frankliniella occidentalis; Matteson et al 1992), this insect appears to be blind to human-visible radiation.…”

“…In the flower thrips Frankliniella occidentalis, Matteson et al (1992) demonstrated the activity of two photoreceptors, one in the UV-A (the sensitivity peak was not determined) and the other in the visible (l max around 545 nm). Attraction of thrips of different species to UV-A radiation has been documented in many previous studies (Costa & Robb 1999;Kumar & Poehling 2006;Nguyen et al 2009).…”

A look into the invisible: ultraviolet-B sensitivity in an insect (Caliothrips phaseoli) revealed through a behavioural action spectrum

Caliothrips phaseoli, a phytophagous insect, detects and responds to solar ultraviolet-B radiation (UV-B; l 315 nm) under field conditions. A highly specific mechanism must be present in the thrips visual system in order to detect this narrow band of solar radiation, which is at least 30 times less abundant than the UV-A (315 -400 nm), to which many insects are sensitive. We constructed an action spectrum of thrips responses to light by studying their behavioural reactions to monochromatic irradiation under confinement conditions. Thrips were maximally sensitive to wavelengths between 290 and 330 nm; human-visible wavelengths (l ! 400 nm) failed to elicit any response. All but six ommatidia of the thrips compound eye were highly fluorescent when exposed to UV-A of wavelengths longer than 330 nm. We hypothesized that the fluorescent compound acts as an internal filter, preventing radiation with l . 330 nm from reaching the photoreceptor cells. Calculations based on the putative filter transmittance and a visual pigment template of l max ¼ 360 nm produced a sensitivity spectrum that was strikingly similar to the action spectrum of UV-induced behavioural response. These results suggest that specific UV-B vision in thrips is achieved by a standard UV-A photoreceptor and a sharp cut-off internal filter that blocks longer UV wavelengths in the majority of the ommatidia.

“…In addition, the impact of light on insect behavior varies both qualitatively and quantitatively depending on the light source (light bulb or light-emitting diode [LED]) and material (light-reflecting plate) (Antignus 2000;Coombe 1981Coombe , 1982Honda 2011;Johansen et al 2011;Matteson et al 1992;Nissinen et al 2008;Prokopy and Owens 1983;Smith 1976). In the remainder of this review, we discuss examples of technologies that are currently being used to control a variety of pests.…”

Insect reactions to light and its applications to pest management

Insects are able to see ultraviolet (UV) radiation. Nocturnal insects are often attracted to light sources that emit large amounts of UV radiation, and devices that exploit this behavior, such as light traps for forecasting pest outbreaks, and electric insect killers, have been developed. Some diurnal species are attracted to yellow; yellow pan traps are used for conducting surveys for pest outbreaks and yellow sticky plates are used for pest control. Lamps that give off yellow illumination have been used effectively to control the activity of nocturnal moths and thus reduce damage to fruit, vegetables, and flowers. Covering cultivation facilities with film that filters out near-UV radiation reduces the invasion of pests such as whiteflies and thrips into the facilities, thus reducing damage. Reflective material placed on cultivated land can control the approach of flying insects such as aphids. Future development and use of new light sources such as light-emitting diodes is anticipated for promoting integrated pest management.

“…Western flower thrips are attuned to spectral radiation in the ultraviolet range (~365 nm) and in the yellow-green range (~540 nm) (Matteson et al, 1992). The yellow-green sensitivity is thought to play a role in long distance orientation to plants, and the ultraviolet sensitivity is part of the visual system to distinguish flowers.…”
