Transcriptomic profiling of the reproductive mode switch in the pea aphid in response to natural autumnal photoperiod
2012, Journal of Insect PhysiologyCitation Excerpt :Second, the spectrum used in controlled chamber tends to mimic the sun light, but it is known that the neon light we used covers essentially visible and ultra-violet waves, but not the entire spectrum of natural light. However, it is known that blue light is necessary for sexual morph production in aphids (Lees, 1981) suggesting that photoperiod detection and sensing might act through blue-light receptors. Thus, the artificial light used in our controlled rooms contains the 540 nm waves corresponding to blue light, insuring sexual morph production.
Deciphering time measurement: The role of circadian 'clock' genes and formal experimentation in insect photoperiodism
2011, Journal of Insect PhysiologyCitation Excerpt :The clock-counter system in these two species of aphid, therefore, might still be explained in terms of a single damping oscillator version of external coincidence. Evidence that light falling on a photoinducible phase, timed to occur at the end of the critical night, acts through a photopigment absorbing at longer wavelengths is provided by work on M. viciae by Lees (1981) and has been reviewed earlier (Saunders, 2009, 2010b). In the Lepidoptera, formal experiments designed to uncover a possible circadian involvement in the photoperiodic phenomenon have provided a variety of responses (reviewed in Saunders, 2002).
Insect photoperiodic calendar and circadian clock: Independence, cooperation, or unity?
2011, Journal of Insect PhysiologyCitation Excerpt :The early scotophase period was maximally sensitive to short wavelengths of 450–470 nm, while the late scotophase period showed considerable extension of sensitivity to longer wavelengths. A similar difference in the spectral sensitivity between the early and late parts of scotophase was also detected in the vetch aphid Megoura viciae (Lees, 1981). Collectively, the input pathways (photic and nonphotic) to the photoperiodic clock and counter appear to be multiple, highly probably redundant, and/or cooperative.
Controversial aspects of photoperiodism in insects and mites
2010, Journal of Insect PhysiologyCuticular proteins and seasonal photoperiodism in aphids
2010, Insect Biochemistry and Molecular BiologyCitation Excerpt :It is known that the cuticle filters the light signal in aphids (Hardie et al., 1981). As different wave lengths are involved in seasonal photoperiodism (Lees, 1981), cuticle modification in response to long-night photoperiods alter these filtering characteristics. We can thus expect that changing day length could lead to modifications in CP composition related to perception of a different quantity of light.
