Or pr\u00e8s de la moiti\u00e9 des esp\u00e8ces connues sont des insectes. Les <strong>insectes forestiers<\/strong> repr\u00e9sentent donc un objet d\u2019\u00e9tude essentiel pour \u00e9valuer la <strong>biodiversit\u00e9 en for\u00eat<\/strong>, suivre son \u00e9volution, pr\u00e9dire sa r\u00e9ponse aux effets de la gestion.<br>Les insectes participent \u00e9galement au fonctionnement de l\u2019\u00e9cosyst\u00e8me forestier en affectant la croissance et la survie des arbres (phytophages), en r\u00e9gulant les populations de phytophages (parasito\u00efdes et pr\u00e9dateurs), ainsi qu\u2019en recyclant la mati\u00e8re organique (saproxyliques).<\/p>\n\n\n\n<p class=\"has-black-color has-text-color\">Au-del\u00e0 de ces fonctions multiples, les insectes forestiers partagent des traits de vie communs en termes de reproduction, dispersion et nutrition, dont la connaissance nourrit des disciplines aussi vari\u00e9es que l\u2019\u00e9thologie, la biologie \u00e9volutive, la biologie de la conservation ou l\u2019\u00e9cologie. Cette connaissance est fond\u00e9e sur l\u2019observation in natura, le suivi de r\u00e9seaux syst\u00e9matiques et le d\u00e9veloppement d\u2019exp\u00e9rimentations. Elle renseigne sur l\u2019\u00e9tat de la biodiversit\u00e9 et la sant\u00e9 des for\u00eats, et permet de pr\u00e9dire leur \u00e9volution et de proposer des solutions pour leur gestion.<\/p>\n\n\n\n<p class=\"has-black-color has-text-color\">Or cette <strong>connaissance des insectes forestiers <\/strong>est diffuse, partag\u00e9e entre naturalistes, scientifiques ou gestionnaires, dispers\u00e9e entre associations, institutions ou p\u00f4les g\u00e9ographiques vari\u00e9s. Il nous est donc apparu qu\u2019un <strong>cadre d\u2019\u00e9change<\/strong> entre tous les <strong>passionn\u00e9s d\u2019entomologie foresti\u00e8re<\/strong> permettrait de mieux partager cette connaissance et donc de progresser ensemble dans notre compr\u00e9hension du fonctionnement des communaut\u00e9s d\u2019insectes forestiers. Ce cadre n\u2019existait pas, nous l\u2019avons cr\u00e9\u00e9 en fondant le Groupe des Entomologistes Forestiers Francophones (GEFF).
