Pourquoi ? Explications sur ce mutualisme entre deux esp\u00e8ces d&#8217;insectes. <br>Les pucerons se nourrissent de s\u00e8ve riche en sucre. Leurs <strong>d\u00e9jections sont ainsi liquides, translucides et sucr\u00e9es<\/strong> : c&#8217;est le miellat. Les <strong>fourmis sont tr\u00e8s friandes de ce miellat<\/strong>, qui peut constituer une source de nourriture importante pour elles.<br>Les fourmis ont donc tout int\u00e9r\u00eat \u00e0 prot\u00e9ger les pucerons, voire \u00e0 les soigner, pour pouvoir b\u00e9n\u00e9ficier de ce miellat. On peut m\u00eame dire qu&#8217;elles les \u00e9l\u00e8vent pour les traire, comme l&#8217;homme le fait avec le b\u00e9tail. Elles <strong>repoussent les pr\u00e9dateurs des pucerons<\/strong>, notamment les<a href=\"https:\/\/www.gerbeaud.com\/jardin\/jardinage_naturel\/syrphe,1990.html\"> larves de syrphes<\/a> et les <a href=\"https:\/\/www.gerbeaud.com\/faune\/coccinelle-insecte-auxiliaire,1071.html\">coccinelles<\/a> (elles sont en revanche inefficaces contre les insectes parasito\u00efdes), et <strong>nettoient la colonie de pucerons<\/strong> en \u00e9liminant les d\u00e9p\u00f4ts de miellat sur les feuilles ainsi que les exuvies (cette &#8220;toilette&#8221; freine le d\u00e9veloppement de champignons n\u00e9fastes pour les pucerons). Elles peuvent m\u00eame <strong>d\u00e9placer les pucerons d&#8217;une tige \u00e0 une autre<\/strong>, voire d&#8217;une plante \u00e0 une autre, quand la s\u00e8ve commence \u00e0 manquer.<\/p><\/blockquote>\n\n\n\n<div class=\"wp-block-buttons is-layout-flex wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link\" href=\"https:\/\/www.gerbeaud.com\/reponses-experts\/fourmis-elevent-pucerons,35.html\" target=\"_blank\" rel=\"noreferrer noopener\">La suite ici&#8230;<\/a><\/div>\n<\/div>\n\n\n\n<!--more-->\n","protected":false},"excerpt":{"rendered":"<p>Fable du jour au jardin. <\/p>\n<p class=\"continue-reading-button\"> <a class=\"continue-reading-link\" href=\"https:\/\/www.rezeau.org\/wp-garden\/fr\/la-fourmi-et-les-pucerons\/\">Continue reading<i class=\"crycon-right-dir\"><\/i><\/a><\/p>\n","protected":false},"author":2,"featured_media":20274,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[677],"tags":[2330],"class_list":["post-20280","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-journal-du-jardin","tag-insectes"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.rezeau.org\/wp-garden\/wp-json\/wp\/v2\/posts\/20280","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.rezeau.org\/wp-garden\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.rezeau.org\/wp-garden\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.rezeau.org\/wp-garden\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.rezeau.org\/wp-garden\/wp-json\/wp\/v2\/comments?post=20280"}],"version-history":[{"count":0,"href":"https:\/\/www.rezeau.org\/wp-garden\/wp-json\/wp\/v2\/posts\/20280\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.rezeau.org\/wp-garden\/wp-json\/wp\/v2\/media\/20274"}],"wp:attachment":[{"href":"https:\/\/www.rezeau.org\/wp-garden\/wp-json\/wp\/v2\/media?parent=20280"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.rezeau.org\/wp-garden\/wp-json\/wp\/v2\/categories?post=20280"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.rezeau.org\/wp-garden\/wp-json\/wp\/v2\/tags?post=20280"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
