(1) However, when the pigmented eyespot is absent, the light penetrates the body and the front-to - back contrast is reduced.(2) The pathogen survives on corn debris, so reduced tillage and continuous corn create a high-risk environment for development of eyespot , especially if there is heavy residue and a history of it in that location.(3) For a second or two, the whale is so close that I can see its white eyespot , and then it dives.(4) Where eyespot is over threshold the preferred fungicide would be cyprodinil although Punch and Landmark both have some activity against eyespot and can give useful control.(5) The percentage of stems affected by damaging lesions of eyespot at 22.1pc was the highest on record.(6) Further, close observations of agonistic interactions revealed that individuals who were the first to display the eyespot were almost invariably the winners and ultimate social dominants.(7) A relationship between eyespot phenotype and N and Dll expression is demonstrated in a loss-of-eyespot mutant in which N and Dll expression is reduced at missing eyespot sites.(8) The eyespot fungus survives in the residue of infected plants for 3 or more years and is most severe under cool, wet conditions.(9) However, this eyespot probably cannot form an acute image but merely acts as a light sensor.(10) There have been reports of Physoderma brown spot, anthracnose, and eyespot developing in Illinois cornfields.(11) Its eyespots , located at the ends of the arms, sense light.(12) However, pigmented eyespots are visible in wild-type larvae and late-stage embryos.(13) Its wings are mottled brown, small eyespots dotting the scalloped edges here and there, small circles with tails on them.(14) The male's head is blue and brown, and both sexes have bold, black eyespots at the napes of their necks.(15) Butterfly eyespots have become a popular model system for the study of evolution and development.(16) The beautiful eyespots on butterfly wings are thought to rely on the principles described above, although involving more morphogens.
