I had the pleasure to chair the #kickoff meeting of #CLARITY new project funded by @EFSA_EU about #Colletotrichum #plantpathogenic species, coordinated by the #plantpathology group of @unito @DISAFA_INT and with expert partners from @Unibo @PlantPathology_ and @isagronomia

The #psyllid #Trioza #urticae is tied to a specific group of #hostplants. They are sometimes perceived by other #insects in shades of #gray and can harbor #plantpathogenic #bacteria. Enemies are predatory insects, like lady beetles. Depending on the predator taxon, the prey is #perceived differently in terms of its #color. The #wavelengths that insects can perceive begin with the UV spectrum and extend below the color red. Therefore, as a small #artistic project, I have presented a specimen in the color that our vertebrate eyes can perceive, a further specimen in which the #reddish parts that are not visible to insects are highlighted, and a third specimen in shades of gray, as it is at least partially seen by various insect predator species. Trioza urticae (#Sternorrhyncha, #Hemiptera) is #hostspecific for stinging nettles (#Urticaceae). The adults overwinter (at least in Central Europe). The nymphs that hatched after mating in the following year induce #galls to their host plant, in which they develop and which cause the leaves to curl and bend, thereby interfering with the growth of the nettle shoots. #Jumpingplantlice can harbor and spread plant pathogenic #microorganisms. Psyllid species spread the bacterium #Candidatus #Liberibacter #solanacearum as an important plant pathogen native to North America that there infects apiaceous and solanaceous #crops. However, the bacterium could already be found in Finland in the form of the so-called #haplotype U on Trioza urticae and U. dioica. The authors M. J. Sjölund et al. (2018) provided the first evidence for the bacterium CLso in Trioza urticae in #Germany. It was found with an unknown haplotype on a T. urticae specimen from a population near the city Quedlinburg (Saxony-Anhalt, Germany). Now I would like to return to the #colorimpression that predators and other insects in general get from T. urticae. This is difficult to define in detail and across insects, as the preferred #colorspectrum can vary from species to species, depending on the ecology, morphology and physiology. The authors Bo-Mi Song & Chi-Hon Lee (2018) dealt with the general “Mechanistic Understanding of #ColorVision in Insects”. Their studies showed at least one commonality in insects, namely that insects have an #oppositionbased processing for “#truecolorvision”. Thus this affects insects as well as vertebrates. Ecology, physiology and eye morphology initially play no role on that general level. © StefanFWirth Berlin Sources : M. J. Sjölund et al.
