Abstract

Raziskali smo anatomske in funkcionalne lastnosti sestavljenih oči in ocelov bojevniške muhe (Hermetia illucens, Linnaeus, 1758). Uporabili smo makroskopsko fotografijo, svetlobno in elektronsko mikroskopijo, spektrofotometrijo in elektrofiziološke meritve. Ugotovili smo, da ima muha oči z odprtim rabdomom z nevralno superpozicijo. Periferni fotoreceptorji imajo tri tipe spektralne občutljivosti: UV-moder, moder, ter zelen. Spektralni tipi so regionalizirani tako, da so kratkovalovni receptorji nameščeni ventralno, dolgovalovni pa dorzalno. V sestavljenem očesu smo našli tudi centralne fotoreceptorje, občutljive na UV in zeleno svetlobo, z visoko polarizacijsko občutljivostjo. Kornea sestavljenih oči je obarvana s strukturnimi barvami, vendar te ne vplivajo na spektralno občutljivost fotoreceptorjev. ERG ocelov nakazuje, da jih sestavljajo tri spektralni razredi fotoreceptorjev, UV, moder in zelen. Podatke smo uporabili pri izdelavi svetil za izboljšanje svetlobnih pogojev za gojenje bojevniške muhe v notranjih prostorih

Secondary title: Color vision in the black soldiers fly (Hermetia illucens)
Secondary abstract: We investigated the anatomical and functional properties of compound eyes and ocelli of the black soldier fly (Hermetia illucens, Linnaeus, 1758). We used macro photography, light and electron microscopy, spectrophotometry and electrophysiological measurements. The compound eyes have open rhabdom and neural superposition. The peripheral photoreceptors have three types of spectral sensitivity: UV-blue, blue, and green. The different spectral types are regionalized so that the short-wavelength receptors are located ventrally, and long-wavelength receptors dorsally. The central photoreceptors were sensitive to UV and green and some had high polarization sensitivity. The cornea of compound eyes is iridescently colored with structural colors, but the coloration does not affect the spectral sensitivity of the photoreceptors. ERG of ocelli suggests that they contain three spectral classes of photoreceptors, UV, blue and green. The data were used to design the optimal lamps for indoor rearing of the black soldier flies.
