“…From an electrophysiological point of view, the waveform of the ERG in L. sericata adults from Colombia (Figure 1) was similar to those reported for other Diptera like Musca domestica, Drosophila melanogaster, Lucilia caesar, Arachnocampa luminosa and Calliphora erythrocephala (Autrum, 1950;Naka & Kuwabara, 1959;Yinon, 1970;Heisenberg, 1971;Kugel, 1977;Meyer & Eguchi, 1984;Babrekar et al, 2004).…”

Lucilia sericata (Meigen, 1826) (Diptera: Calliphoridae) is a synanthropic fly with a worldwide distribution that pollinates plants and is relevant in medical, veterinary, and forensic sciences. L. sericata is a diurnal species whose vision plays an important role in spatial orientation. Here we evaluated the electrophysiological responses (ERG) of L. sericata’s compound eyes in adults of both sexes from Colombia and their behavioral attraction to LED lights with different wavelengths. The ERG revealed a dichromatic vision with peaks at blue (450 nm) and green (510-530 nm) wavelengths in individuals of both sexes. Behavioral experiments with a two-sided light tunnel showed that both sexes were mainly attracted to blue, white, and red lights of different intensities (0.34, 0.15, and 0.034 μW/cm2). Attraction to the lights decreased at lower intensities; however, attraction to blue, white, and red lights was still observed. The electrophysiological and behavioral results we obtained in the laboratory were complementary and explain how Colombian untrained L. sericata adults interact with their environment using mainly the sunlight wavelengths reflected under natural conditions.

“…Asterisks indicate significant differences among colors per day (one-way ANOVA: P<0.05). However, further experiments are required to test this hypothesis, e.g., analysis of peaks in the spectral sensitivity of the ommatidia of E. vitis in electroretinograms (Babrekar et al, 2004;Kirchner et al, 2005). However, humans cannot distinguish a polychromatic yellow from truly monochromatic yellow (Yang & Chen, 2008).…”

The tea leafhopper, Empoasca vitis (G€ othe) (Hemiptera: Cicadellidae), is a major pest of the tea plant, Camellia sinensis (L.) O. Kuntze (Theaceae). In this study, the RGB color model was used to describe the colors of sticky traps. The most effective color for attraction of E. vitis was investigated by orthogonal optimization. The selected color was verified in tea gardens and the most effective height for positioning of color sticky traps for capturing tea leafhoppers was investigated. After the determination of the effect of the three color parameters and their interactions by orthogonal optimization, the color gold (RGB: 255, 215, 0) was selected as the most effective color to trap tea leafhoppers. In tea gardens, more leafhoppers were captured using gold sticky traps (RGB: 226, 204, 4) than using commercially available yellow sticky traps. The most effective height of gold sticky traps for trapping leafhoppers was 40-60 cm above the tea canopy. Few lady beetles were captured at this height. We conclude that the orthogonal optimization method is a convenient and efficient method to screen digitally generated colors for attracting and trapping of pests.

Two thrips species-the yellow tea thrips (Scirtothrips dorsalis Hood) and the stick tea thrips (Dendrothrips minowai Priesner)-are serious pests affecting tea plants in southern China. Although the stick tea thrips is primarily restricted to southern China, the yellow tea thrips is gradually proliferating worldwide. Colored sticky card traps may be useful for monitoring and capturing these species, but a systematic analysis has not been conducted to identify the most effective trap color, height, and orientation. We performed indoor experiments using an orthogonal experimental design, as well as field tests in tea gardens, to identify the color most attractive to the two thrips species. Field tests were then conducted using color-optimized traps-lawngreen (RGB: 124, 252, 0) for yellow thrips and lime (RGB: 0, 255, 0) for stick tea thrips-to determine the most effective trap height and orientation. The greatest numbers of both yellow and stick tea thrips were captured on traps positioned 0-20 cm above the tea canopy in an east-west orientation. We also evaluated the performance of the color-optimized sticky card traps compared with commercially available yellow ones. Significantly more yellow and stick tea thrips and fewer natural enemies were captured on the color-optimized traps than on commercial ones. Although additional research is needed to explain the responses of the two different species and to increase trap effectiveness, our findings should assist in the control of these harmful insects.
