Phototoxicity of porphyrins toward drosophila melanogaster

    Abstract
  •   Objective   To investigate the phototoxic activity of tetra-(4-methyl)phenyl-porphine(TMPP)toward drosophila melanogaster.
      Methods   The flies were randomly grouped with 20 flies in each by ether anesthesia.The response of flies to irradiation was determined as by the following par ameters: TMPP concentration in the bait(0.5-2.0 g/L); irradiation time(1-2 h); and irradiation intensity(one or two 40 W electric incandescent lamps).
      Results   It was showed that the mortality of the TMPP-fed flies to light was increased with the increase of TMPP concentration in the bait, the extending of irradiation time and the elevating of irradiation intensity.Under the same condition, TMPP showed stronger phototoxic activity than Pa.
      Conclusion   TMPP was a favorable photosensitizer and can be used for insect control.Light played an important role in its phototoxicity.
