“…16,32 , putting up red-colored nets at the openings of greenhouses and around the elds can also signi cantly reduce T. tabaci invasion. In this study, red-colored nets effectively kept the population of T. tabaci on leafs low, consistent with report in Ohya et al (2022) 15 . In addition, we found a lower rate of leaf damage (Fig.…”

“…Therefore, the pest controlling effect could be due to the long-wavelength component of the re ected light from the net stimulating the green photoreceptor cells in thrips. The pest control effect of other reported red light and materials on thrips 11,15,29,30 could also be explained by the blue-and green-sensitive photoreceptors as well, but further analyses are needed. Ohya et al ( 2022) 15 have reported on the effectiveness of red nets in controlling insects.…”

Development of advanced pest control methods that do not rely on insecticides is an important issue for sustainable agriculture. Particularly with regards to micro pests that are not only highly resistant to various insecticides but also because we are running out of options for which insecticide to use against them, resulting in enormous economic damage worldwide. Here we report that the effectiveness of the conventional insect net can be greatly advanced by changing their color to red that helps significantly reduce pesticide use. We demonstrate the red effect using Onion thrips, Thrips tabaci a main vector of Iris Yellow Spot Virus (IYSV) and Tomato Spotted Wilt Virus (TSWV) that cause serious damage to various vegetables. New red nets succeeded in suppressing the invasion rates and damages (white spots on the leaves) in a Welsh onion greenhouse with minimum use of pesticides. We discuss how red nets are compatible with labor-saving, sustainable agriculture and the future potential of “optical pest control” based on insect color vision and its behavioral response.

“…At that time, this phenomenon was not expected to lead to a completely new pest control technology. However, as a result of improvements over the years 12 – 15 , we have succeeded in developing a new concept with insect nets that effectively prevents pest invasion and crop damage in cultivation facilities. Since the mesh size can be larger than the size of pests, it is also possible to increase light transmittance and reduce incidence of mold diseases such as powdery mildew.…”

Sensory stimuli are essential for arthropod survival and reproduction. Given the widespread use of vibrational communication among diverse taxa, exploiting vibrational senses has great potential for successful pest management. In this review, we summarize our recent findings on vibration‐based pest management and future perspectives in the context of integrated pest management. We first examine the management of whiteflies – the tobacco whitefly, Bemisia tabaci (Gennadius) and the greenhouse whitefly, Trialeurodes vaporariorum (Westwood) (Hemiptera: Aleyrodidae) – in various facilities where tomatoes are cultivated. We then explore the recent application of vibration for the control of fungus gnats of the genus Neoempheria (Diptera: Mycetophilidae) infesting shiitake mushrooms. Finally, we discuss the control of the brown‐winged green stink bug, Plautia stali Scott (Hemiptera: Pentatomidae), a pest of fruit trees in Japan. Notably, our trials have demonstrated that vibrational treatments are profitable not only for reducing pest populations but also for indirect benefits such as increased crop yields or the enhancement of pest control effectiveness.
