La gu\u00eape asiatique de la ch\u00e2taigne endommage les ch\u00e2taigniers en provoquant la formation de galles.<\/figcaption><\/figure>\n<\/figure>\n\n\n\n

Pendant pr\u00e8s de deux d\u00e9cennies Anthesis<\/a> a fourni des solutions de biocontr\u00f4le et de bionutrition aux producteurs, les aidant \u00e0 surmonter les probl\u00e8mes de r\u00e9sidus, \u00e0 g\u00e9rer la r\u00e9sistance des ravageurs aux ingr\u00e9dients actifs et \u00e0 contribuer de mani\u00e8re significative \u00e0 la lutte contre les ravageurs probl\u00e9matiques. La r\u00e9alisation la plus r\u00e9cente est le contr\u00f4le efficace de la gu\u00eape asiatique de la ch\u00e2taigne (Dryocosmus kuriphilus<\/em>) en utilisant la gu\u00eape parasito\u00efde Torymus sinensis.

La gu\u00eape asiatique de la ch\u00e2taigne est originaire de Chine et a \u00e9t\u00e9 introduite accidentellement en Europe par l'Italie. Elle endommage gravement les ch\u00e2taigniers en provoquant la formation de galles. Celles-ci apparaissent au printemps et interf\u00e8rent avec la croissance normale de la plante, r\u00e9duisant la fructification et provoquant un d\u00e9p\u00e9rissement progressif du ch\u00e2taignier.

La difficult\u00e9 de lutter contre la gu\u00eape asiatique du ch\u00e2taignier avec des m\u00e9thodes conventionnelles r\u00e9side dans le fait que la grande majorit\u00e9 du cycle de vie du ravageur se d\u00e9roule \u00e0 l'int\u00e9rieur des galles et sur les arbres de grande taille que l'on trouve g\u00e9n\u00e9ralement dans les ch\u00e2taigneraies traditionnelles, ce qui rend les applications de pesticides assez difficiles. Pendant de nombreuses ann\u00e9es, les producteurs se sont retrouv\u00e9s dans une impasse, voyant la d\u00e9gradation de leurs vergers s'accentuer ann\u00e9e apr\u00e8s ann\u00e9e.

En 2017, Anthesis a introduit, initialement \u00e0 titre exp\u00e9rimental, la gu\u00eape parasito\u00efde Torymus sinensis en collaboration avec la soci\u00e9t\u00e9 Pegaso et l'universit\u00e9 italienne de Turin. Cette gu\u00eape sp\u00e9cifique recherche activement les galles et y d\u00e9pose ses \u0153ufs, \u00e0 proximit\u00e9 des larves de la gu\u00eape asiatique de la ch\u00e2taigne. Apr\u00e8s l'\u00e9closion des \u0153ufs, les jeunes larves se nourrissent des larves ou des pupes de la gu\u00eape asiatique du ch\u00e2taignier et emp\u00eachent ainsi toute nouvelle infestation de la jeune v\u00e9g\u00e9tation. Progressivement, apr\u00e8s pr\u00e8s de 6 \u00e0 7 ans, elle r\u00e9duit la population au point de permettre la reprise des ch\u00e2taigneraies.

Sur la base de ce succ\u00e8s, en 2018 Torymus sinensis<\/em> a \u00e9t\u00e9 mis \u00e0 la disposition des agriculteurs qui, \u00e0 leur tour, ont commenc\u00e9 \u00e0 rel\u00e2cher le parasito\u00efde chaque ann\u00e9e, sous la supervision du d\u00e9partement technique d'Anthesis. L'\u00e9quipe d'Anthesis a collect\u00e9 des milliers de galles et a soigneusement examin\u00e9 leur contenu dans les zones de culture de ch\u00e2taigniers de toute la Gr\u00e8ce afin de v\u00e9rifier que les l\u00e2chers de parasito\u00efdes \u00e9taient bien effectu\u00e9s. Torymus sinensis<\/em> a donn\u00e9 les r\u00e9sultats escompt\u00e9s.

Au cours de chaque hiver, des journ\u00e9es de terrain et des pr\u00e9sentations concernant Torymus sinensis<\/em> Les avantages du l\u00e2cher et les progr\u00e8s de la lutte contre la gu\u00eape gallicole asiatique du ch\u00e2taignier dans diff\u00e9rentes zones ont \u00e9t\u00e9 r\u00e9alis\u00e9s. Peu \u00e0 peu, la majorit\u00e9 des cultivateurs ont commenc\u00e9 \u00e0 faire confiance \u00e0 cette m\u00e9thode et sont pass\u00e9s des m\u00e9thodes conventionnelles aux l\u00e2chers d'insectes. Torymus sinensis<\/em>.

De nos jours, le niveau de parasitisme et donc le r\u00e9tablissement des ch\u00e2taigneraies grecques que Torymus sinensis<\/em> appliqu\u00e9 est impressionnant. La mentalit\u00e9 des producteurs \u00e0 l'\u00e9gard des m\u00e9thodes de biocontr\u00f4le est tr\u00e8s positive et soul\u00e8ve des questions sur les utilisations traditionnelles des pesticides conventionnels. La majorit\u00e9 des producteurs sont maintenant convaincus de l'\u00e9norme potentiel des solutions de biocontr\u00f4le, car il existe de nombreux exemples o\u00f9 ces m\u00e9thodes sont le seul moyen de contr\u00f4ler les ravageurs probl\u00e9matiques.<\/p>\n\n\n\n
