With　more　and　more　loss　caused　by　forest　biological　disasters　(FBDs)　in　China,　forest　farmers,　as　one　of　the　most　important　stakeholders,　are　participating　in　the　control.　In　this　study,　the　ordinary　least　squares　model,　simultaneous　equation　model,　and　propensity　score　matching　method　were　used　with　the　data　from　818　surveys　conducted　in　the　typical　FBD　outbreak　provinces,　to　reveal　the　FBD　control　behaviors　of　forest　farmers　and　their　differences　between　western　and　eastern　regions　of　China.　The　results　indicated　the　following.　(1)　Household　factors:　forest　farmers　could　timely　take　control　measures.　An　increase　of　1　ha　in　the　area　of　occurrence　would　increase　the　control　measures　by　3.26　ha.　However,　the　control　measures　can　only　reduce　50%　of　the　economic　loss　caused　by　FBDs　and　cannot　effectively　control　the　spread　trend　of　FBDs.　There　are　issues,　including　an　insufficient　and　old　labor　force,　insufficient　technology　support,　and　low　consciousness　of　ecology　protection.　(2)　External　factors:　forest　farmers　would　increase　control　when　the　temperature　rises,　and　reduce　control　when　rainfall　increases.　After　village　committees　unify　organizing　the　control,　their　participation　enthusiasm　would　increase,　which　would　have　a　substitution　relationship　with　the　household　investment.　(3)　Regional　difference:　the　eastern　region　of　China　has　higher　figures　than　the　western　in　terms　of　outbreak　area,　economic　losses,　control　measures,　and　pesticide　cost.　If　the　western　forest　farmers　have　the　control　funds　as　the　eastern　forest　farmers　have,　and　the　eastern　forest　farmers　have　the　control　intensity　as　the　western　forest　farmers　have,　the　overall　FBD　control　effect　would　be　better.
