Spectral sensitivity of the dorsal compound eye of Simuliid males (Nematocera) shows a maximum in the u.v. at 340 nm, and a shoulder or second, smaller maximum around 430 nm. The visual pigment--based on retinal and therefore a rhodopsin--has its absorption maximum at 430 nm. The 340 maximum is due to a sensitizing pigment that transfers energy to the visual pigment. The properties of the Simuliid-photoreceptor hence are similar to most of the photoreceptors in higher flies (Musca, Calliphora, Drosophila), that also have a u.v.-absorbing sensitizing pigment. The difference is that in Simuliids the sensitizing pigment is not 3-hydroxyretinol as in the higher flies but a different substance, most likely retinol.
蚋科雄性(双翅目长角亚目)复眼背侧的光谱敏感性在紫外光区340纳米处有一个最大值,在430纳米左右有一个肩峰或第二个较小的最大值。基于视黄醛因而属于视紫红质的视觉色素,其吸收最大值在430纳米处。340纳米处的最大值是由于一种敏化色素将能量传递给了视觉色素。因此,蚋科光感受器的特性与大多数高等蝇类(家蝇、丽蝇、果蝇)的光感受器相似,这些高等蝇类也有一种吸收紫外光的敏化色素。不同之处在于,在蚋科中,敏化色素不像在高等蝇类中那样是3-羟基视黄醇,而是一种不同的物质,很可能是视黄醇。
