Les pucerons<\/h2>\n

Les pucerons <\/strong>sont des insectes nuisibles aux cultures maraich\u00e8res, certaines esp\u00e8ces d\u00e9veloppent des colonies importantes sur la pomme de terre. Parmi les esp\u00e8ces qui s\u2019attaquent \u00e0 la culture de la pomme de terre, on y trouve le puceron vert et rose de la pomme de terre Macrosiphum euphorbiae<\/em>, le puceron tachet\u00e9 de la pomme de terre Aulacorthum solani <\/em>et puceron vert du p\u00eacher Mysus persicea<\/em>, le puceron vert de la f\u00e8ve Aphis fabae solanella<\/em>.<\/p>\n<\/div>

Cycle de d\u00e9veloppement des pucerons<\/h2>\n

Les pucerons hivernent sous forme d\u2019\u0153ufs sur les plantes h\u00f4tes. \u00c0 une temp\u00e9rature comprise entre 15 et 28 \u00b0C, les \u0153ufs \u00e9closent et donnent des larves fondatrices. Ces derni\u00e8res se reproduisent par parth\u00e9nogen\u00e8se pour donner des pucerons apt\u00e8res et ail\u00e9s. Ce sont ces pucerons ail\u00e9s qui vont assurer la dispersion sur d\u2019autres plantes h\u00f4tes de la m\u00eame esp\u00e8ce. \u00c0 des temp\u00e9ratures favorables, plusieurs g\u00e9n\u00e9rations se succ\u00e8dent par parth\u00e9nog\u00e9n\u00e8se.
\nEn automne, les femelles produisent des m\u00e2les ail\u00e9s et des femelles apt\u00e8res ovipares qui s\u2019accouplent pour que les femelles f\u00e9cond\u00e9es pondent les \u0153ufs d\u2019hiver.<\/p>\n<\/div>

Sympt\u00f4mes et d\u00e9g\u00e2ts<\/h2>\n

Sur feuilles et jeunes pousses : des ponctuations chlorotiques dues aux piqueurs nutritionnelles, les larves et les adultes sont observ\u00e9s \u00e0 la face inf\u00e9rieure des feuilles. Le miellat s\u00e9cr\u00e9t\u00e9 favorise le d\u00e9veloppement de la fumagine qui influence la capacit\u00e9 de la plante \u00e0 effectuer la photosynth\u00e8se.
\nCertaines esp\u00e8ces sont vecteurs de maladies \u00e0 virus. C\u2019est le cas de Myzus persicea<\/em> qui transmet efficacement le virus de l\u2019enroulement et le virus de la mosa\u00efque jaune.<\/p>\n<\/div>

Strat\u00e9gie de lutte<\/h2>\n

Mesures prophylactiques :<\/strong>
\n\u2022 D\u00e9truire les r\u00e9sidus de cultures pr\u00e9c\u00e9dentes.
\n\u2022 D\u00e9sherber la parcelle et les bordures pour \u00e9liminer la source de l\u2019infection.
\n\u2022 Apporter une fertilisation \u00e9quilibr\u00e9e en azote.
\n\u2022 Une surveillance r\u00e9guli\u00e8re des populations le long du cycle permet d\u2019intervenir \u00e0 temps.<\/p>\n

Lutte chimique :<\/strong>
\nLev\u00e9e :<\/strong> \u00c0 ce stade, si les conditions sont favorables pour l\u2019\u00e9closion des \u0153ufs et l\u2019apparition des larves, nous recommandons l\u2019utilisation de Wide\u00ae<\/sup><\/strong>, \u00e0 la dose de 0,3 kg\/ha<\/strong>.<\/p>\n

Croissance active :<\/strong> \u00c0 ce stade, les conditions sont propices au d\u00e9veloppement du puceron. Nous recommandons un traitement avec Wide\u00ae<\/sup><\/strong>, \u00e0 la dose de 0,3 kg\/ha<\/strong>.
\nCe traitement poss\u00e8de une bonne persistance d\u2019action et assure la protection int\u00e9grale de la plante ainsi que des nouvelles feuilles qui apparaissent, gr\u00e2ce \u00e0 une syst\u00e9mie ascendante et descendante.<\/p>\n

V\u00e9g\u00e9tation stabilis\u00e9e :<\/strong> \u00c0 ce stade, si les conditions restent favorables au d\u00e9veloppement du puceron, nous recommandons l\u2019application de Wide\u00ae<\/sup><\/strong>, \u00e0 la dose de 0,3 kg\/ha<\/strong>, puis de revenir avec un traitement avec Deltharin\u00ae<\/sup><\/strong>, \u00e0 la dose de 0,5 L\/ha<\/strong> en cas de r\u00e9-infestations par le ravageur.
\nCe traitement assure \u00e9galement le contr\u00f4le des noctuelles et de la teigne.<\/p>\n<\/div><\/div><\/div><\/div><\/div>
