Absorption of Musca domestica Screening Pigment

چکیده
[Brief letters to the Editor that make specific scientific reference to papers published previously in THE JOtrRNAL OF GENERAL PHWSIOLOOY are invited. Receipt of such letters will be acknowledged, and those containing pertinent scientific comments and scientific criticisms will be published.] Dear Sir: The recent article entitled "Do Flies Have a Red Receptor?" by Goldsmith (1) answers this question very nicely in the negative. Further support for this conclusion is now available, as described below.

Microspectrophotometry of Arthropod Visual Screening Pigments
Absorption spectra of visual screening pigments obtained in vitro with a microspectrophotometer using frozen sections are given for the insects Musca domestica, Phormia regina, Libellula luctuosa, Apis mellifera (worker honeybee only), Drosophila melanogaster (wild type only) and the arachnids Lycosa baltimoriana and Lycosa miami. The spectral range covered is 260-700 nm for Lycosa and Drosophi...
متن کاملVisual acuity of fly photoreceptors in natural conditions--dependence on UV sensitizing pigment and light-controlling pupil.
The effect of the UV-absorbing sensitizing pigment of fly photoreceptors on absolute, spectral and angular sensitivity was investigated with a wave-optics model for the facet lens-rhabdomere system. When sky light was used as a UV-rich light source, one sensitizing pigment molecule per rhodopsin increased the photoreceptor absorption by 14-18% with respect to pure rhodopsin, whilst two sensitiz...
متن کاملبررسی پارازیتیسم تجربی مگس های سینانتروپ Musca domestica ، Lucilia sericata و Sarcophaga haemorrhoidalis توسط زنبورهای پارازیتوئید Nasonia vitripennis ، Pachycrepoideus vindemmiae و Spalangia nigroaenea
Background and purpose: One of the most popular methods to control the synanthropic flies is using parasitoid wasps. The aim of this study was to estimate the experimental parasitism rates of pupae of Musca domestica, Lucilia sericata, and Sarcophaga heamorrhoidalis by parasitoid wasps, including Nasonia vitripennis, Spalangia nigroaenea, and Pachycrepoideus vindemmiae. Materials and methods: ...
متن کاملFluorescence of photoreceptor cells observed in vivo.
Most rhabdomeres in the eye of the fly (Musca domestica) are fluorescent. One kind of fluorescent emission emanates from a photoproduct of the visual pigment, other kinds may be ascribed to photostable pigments. These phenomena provide not only a means of spectrally mapping the retina but also a new spectroscopic tool for analyzing the primary visual processes in vivo.

A case of myiasis due to Musca domestica describes in Pseudocerastes persicus for the first time. The snake was found in Bari Karafs, Kashan, Iran, with a lesion on its body. Fourteen live larvae of M. domestica removed from its wound. This is the first report of a new larval habitat of M. domestica.
