She and her team wondered if moths \u2014 which could theoretically hear in the high frequency range of the clicks \u2014 might use that information to their advantage when selecting plants to host their young.<\/p>\n\n\n<aside class=\"sn-conversion rich-text rich-text--with-sidebar\">\n<style><![CDATA[\n.email-conversion {\n  border: 1px solid #ffcccb;\n  color: white;\n  margin-top: 50px;\n  background-image: url(\"\/wp-content\/themes\/sciencenews\/client\/src\/images\/cta-module@2x.jpg\");\n  padding: 20px;\n  clear: both;\n}\n\n]]><\/style>\n\n\n\n<div class=\"rich-text embedded-conversion-content is-layout-flow wp-block-group-is-layout-flow\">\n<a href=\"https:\/\/docs.google.com\/forms\/d\/e\/1FAIpQLSf83OekELCTbhuYw3Iu-p8OWiE9-uE56ZFNbeTapotBaa1rIg\/viewform?usp=sf_link\">\n  <\/a><\/div><a href=\"https:\/\/docs.google.com\/forms\/d\/e\/1FAIpQLSf83OekELCTbhuYw3Iu-p8OWiE9-uE56ZFNbeTapotBaa1rIg\/viewform?usp=sf_link\">\n<\/a>\n\n<style><![CDATA[\n#dynamic-conversion {\n  border: 1px solid #ffcccb;\n  max-width: 100%;\n  height: auto;\n  clear: both;\n}\n]]><\/style>\n\n\n\n\n<\/aside>\n\n\n<p>The researchers placed fertile female Egyptian cotton leafworm moths (<em>Spodoptera littoralis<\/em>) in an arena with speakers playing the sounds of a dehydrated tomato plant on one side and silence on the other. The moths preferentially laid their eggs near the speaker making the distressed clicks, the team found.<\/p>\n\n\n\n<p>\u201cHowever, the plot thickened when we introduced actual plants into the setup,\u201d Seltzer says.\u00a0<\/p>\n\n\n\n<p>When the team ran experiments with no speakers, but a hydrated tomato plant on one side of the arena and a thirsty one on the other, the moths switched their preference, opting for the silent hydrated plant. In one experiment, the team placed a hydrated plant on each side of the arena and a speaker on one of those sides playing distressed clicks. The moths laid more eggs on the plant on the silent side.\u00a0<\/p>\n\n\n\n<p>With no actual plants present for moths to identify with other senses, the researchers write, the sounds of a drying plant are sole indicators of vegetative life, suggesting only one option for raising caterpillars. But with access to plants that the moths can see and smell, the insects can now choose between plants, avoiding those that sound stressed and opting for a potentially healthier host.<\/p>\n\n\n\n<p>\u201cFemale moths not only recognize these sounds as being made by plants but also connect them to the physiological state of the plants,\u201d Seltzer says. \u201cIt\u2019s fascinating to consider how much information exists below the threshold of human hearing.\u201d<\/p>\n\n\n\n<p>Notably, these moths had no prior exposure to plants, being reared entirely in the lab. So being attuned to the plants\u2019 clicking is deeply rooted in their genetics, Seltzer says.<\/p>\n\n\n\n<p>Bj\u00f6rn Thorin Jonsson, a biologist at the University of Graz in Austria, notes: \u201cIf you can detect an acoustic cue that is widespread, reliable and can be beneficial for selecting better food or more suitable [egg-laying] sites, why not use it?\u201d<\/p>\n\n\n\n<p>Sensory biologist Fernando Montealegre-Zapata of the University of Lincoln in England wonders if there could be agricultural applications of the plants\u2019 noise. \u201cCould the playback of stress acoustic cues be implemented in integrated pest management programs to discourage moths from [laying eggs] on healthy plants?\u201d<\/p>\n\n\n\n<p>Seltzer thinks this kind of response to plant noises may be widespread among insects and plants. Many insects have ultrasonic hearing capable of hearing plant clicking.<\/p>\n\n\n\n<p>\u201cI believe that this discovery is just the beginning of understanding the acoustic interactions between animals and plants,\u201d she says.<\/p>\n\n\n\n\t\t\t<\/div>\r\n<br>\r\n<br><a href=\"https:\/\/www.sciencenews.org\/article\/thirsty-plant-screams-moths-lay-eggs\">Source link <\/a>","protected":false},"excerpt":{"rendered":"<p>If you\u2019re a female moth, finding the best plant to host your young may be as simple as taking a close listen.\u00a0 When low on water, some plants make high-pitched clicking noises, inaudible to humans.
