Spectral properties of the visual system of leptinotarsa decemlineata coleoptera chrysomelidae


, : Spectral properties of the visual system of leptinotarsa decemlineata coleoptera chrysomelidae. Zoologische Beitraege 27(2-3): 319-334

ERG [electro retinogram] records of Galeruca tanaceti, Cassida viridis and L. decemlineata (Chrysomelidae) show spectral sensitivities typical of insects. The sensitivity ranges from long wave UV (tested from 318 nm) to short wave red. At .apprx. 650 nm, it is < 1% of the maximum. The sensitivity functions in the 3 spp. have maxima at .apprx. 360 and 510 nm. Optomotor turning reactions were induced in the stationary walking response with a Y-maze globe in Leptinotarsa by moving spectral patterns. The stimulus efficiency was analyzed at different intensity contrasts in white light, in the range of the spectral sensitivity maxima and in 2 color contrast (UV green). The Colorado potato beetle showed quantifiable responses. The heterochromatic contrast function has a minimum near .DELTA. W = 0. Leptinotarsa is color-blind in the context of optomotorics.
