Cette diversit\u00e9 est haute dans les sites o\u00f9 la PFF est absente, et chute s\u00e9v\u00e8rement \u00e0 la suite d&rsquo;infestations. D&rsquo;autres \u00e9tudes ont montr\u00e9 que la PFF peut avoir des impacts indirects sur la diversit\u00e9 des l\u00e9zards (Jourdan et al. 2001), des impacts directs sur les tortues et les oiseaux (Lowe et al. 2000, Wetterer &amp;Porter 2003) et sur les animaux domestiques tels que les chiens et les chats (Wetterer et al. 1999) et leurs homologues sauvages (Walsh et al. 2004)..<\/p>\n<p>Du fait du nombre \u00e9lev\u00e9 d\u2019individus de PFF pouvant se trouver dans une zone, les impacts sur la diversit\u00e9 et la densit\u00e9 des invert\u00e9br\u00e9s dans le milieu peuvent \u00eatre tr\u00e8s importants et provoquer des bouleversements majeurs (Clark et al. 1982).<\/p>\n<p>La PFF se nourrit notamment d\u2019invert\u00e9br\u00e9s, de miellat et de plantes en fonction des p\u00e9riodes de l\u2019ann\u00e9e. Bruneau de Mir\u00e9 (1969) a montr\u00e9 que dans des zones infest\u00e9es par <em>W. auropunctata<\/em>, les populations des autres insectes ont diminu\u00e9, \u00e0 l\u2019exception de celles des homopt\u00e8res comme les cochenilles ou les pucerons. Ceci s\u2019explique par le fait que les petites fourmis de feu se nourrissent de miellat, l&rsquo;excr\u00e9tion sucr\u00e9e produite par les homopt\u00e8res\u00a0; en \u00e9change, elles les prot\u00e8gent des parasites et des pr\u00e9dateurs.<\/p>\n<p>Elle modifie les ressources alimentaires disponibles pour les oiseaux insectivores et d\u00e9s\u00e9quilibre la cha\u00eene alimentaire.<\/p>\n<h3>Que peut-on faire contre cet insecte?<\/h3>\n<p>Pour limiter la prolif\u00e9ration de cet insecte, il est important d&rsquo;\u00e9liminer les zones propices \u00e0 son d\u00e9veloppement (recoins humides notamment, tas d&rsquo;herbe, zones ombrag\u00e9es&#8230;.). Il est \u00e9galement important de ne pas transporter de reines depuis le lieu infest\u00e9 vers une autre zone encore indemne (par le transport de v\u00e9g\u00e9taux et autres mat\u00e9riaux infest\u00e9s).<\/p>\n<p>Pour ce qui concerne les traitements, bien que nous pr\u00e9conisons autant que possible de r\u00e9duire la lutte chimique dangereuse pour la sant\u00e9 humaine et l\u2019environnement, il existe des produits dans le commerce pour lutter contre les fourmis.<\/p>\n<p>Il faut privil\u00e9gier l&rsquo;utilisation d&rsquo;app\u00e2ts \u00e0 effet retard de mani\u00e8re \u00e0 atteindre le couvain et les reines.<\/p>\n<p>Enfin il est possible de faire appel \u00e0 des professionnels du traitement de la m\u00eame mani\u00e8re que dans le cas
