“…Therefore, the pest controlling effect could be due to the long-wavelength component of the reflected 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 15 have reported on the effectiveness of red nets in controlling insects.…”

“…In 2015, an interesting phenomenon was discovered in insect behavior. It was observed that thrips density decreases when crops are irradiated with red light (wavelength 650–750 nm), which is invisible to these pests 11 . At that time, this phenomenon was not expected to lead to a completely new pest control technology.…”

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.

“…Similarly, blue sticky traps have been used to monitor populations of melon thrips, Thrips palmi (Karny) (Thysanoptera: Thripidae) [18] and bean flower thrips, Megalurothrips usitatus (Bagrall) (Thysanoptera: Thripidae) [19]. Recent analyses of the wavelength-specific behavior of insects revealed that thrips density was significantly suppressed in the presence of red light (600-660 nm) [18,20,21]. Based on these findings, Shimoda [22] noted the possibility that both red lighting and red-netting could be effectively used to control thrips species.…”

Our aim was to develop an electrostatic apparatus to lure and capture silverleaf whiteflies (Bemisia tabaci), vegetable leafminers (Liriomyza sativae), and western flower thrips (Frankliniella occidentalis) that invade tomato greenhouses. A double-charged dipolar electric field producer (DD-EFP) was constructed by filling water in two identical transparent soft polyvinyl chloride tubes arrayed in parallel with fixed separation, and then, inserting the probes of grounded negative and positive voltage generators into the water of the two tubes to generate negatively and positively charged waters, respectively. These charged waters electrified the outer surfaces of the opposite tubes via dielectric polarization. An electric field formed between the oppositely charged tubes. To lure these phototactic insects, the water was colored yellow using watercolor paste, then introduced into the transparent insulator tubes to construct the yellow-colored DD-EFP. This apparatus lured insects in a manner similar to commercially available yellow sticky traps. The yellow-colored DD-EFP was easily placed as a movable upright screen along the plants, such that invading pests were preferentially attracted to the trap before reaching the plants. Furthermore, pests settling on the plants were attracted to the apparatus, which used a plant-tapping method to drive them off the plants. Our study provided an experimental basis for developing an electrostatic device to attract and capture insects that enter greenhouses.
