Infra-red Receptors in Melanophila acuminata DeGeer

  title={Infra-red Receptors in Melanophila acuminata DeGeer},
  author={W. G. Evans},
A NUMBER of insects of different orders have been reported swarming near various sources of fire and smoke, although the families Buprestidae (Coleoptera), Platy-pezidae and Empididae (Diptera) have received the greatest attention. The most well-known insect associated with fires, however, is a species of Buprestid, Melanophila acuminata, which has been reported as being attracted over long distances to a variety of burning materials such as wood, oil, mill refuse, smelter products and trash in… Expand
Melanophila unicolor Gory, 1841 (Buprestidae), the Furnace Beetle, in Southern Africa
Recently, large numbers of Melanophila unicolor Gory, 1841 were attracted to furnaces and cooling copper at a smelter at Tsumeb, Namibia, where the beetles are colloquially known asExpand
Fluorescence of the “fire-chaser” beetle Melanophila acuminata
Abstract Melanophila acuminata beetles are attracted to forest fires over long distances by a pair of specialized infrared sensory organs. To date, there is no knowledge of their ability to detect orExpand
Mechanism of infrared detection and transduction by beetle Melanophila Acuminata
Mathematical calculations showed that the physical properties of the sensilla are such that the expected temperature rise is insufficient for transduction of the infrared signal through mechanical means or as a thermal receptor as previously thought; hence the protein plays the pivotal role in perception of single photons and transmission of the signal within the sensillas.

Concept of an Active Amplification Mechanism in the Infrared Organ of Pyrophilous Melanophila Beetles
The theoretical concept of an active amplification mechanism in a photon receptor innervated by highly sensitive mechanoreceptors is presented in this article and it is proposed that flying beetles make use of muscular energy coupled out of the flight motor to considerably increase the sensitivity of their IR sensilla during intermittent search flight sequences.

The complete mitochondrial genome of the pyrophilous jewel beetle Melanophila acuminata (Coleoptera: Buprestidae)
Abstract The complete mitochondrial of genome Melanophila acuminata (DeGeer 1774) is a typical double-stranded circular molecule of 15,853 bp (GenBank accession number: MW287594). All tRNA genes,Expand
The infrared receptor of Melanophila acuminata De Geer (Coleoptera: Buprestidae): ultrastructural study of a unique insect thermoreceptor and its possible descent from a hair mechanoreceptor.
It is concluded that the infrared sensilla of Melanophila acuminata are probably derived from hair mechanoreceptors, and a model of the possible function of the infrared receptor is presented. Expand
The ability of Rhodnius prolixus (Hemiptera; Reduviidae) to approach a thermal source solely by its infrared radiation.
The results show that Rhodnius prolixus can use infrared stimuli to find a host and is able to approach a pure IR source only by its long-wave infrared radiation. Expand
Diversity and Ecology of Saproxylic Hemiptera
