This　study　investigates　a　modified　Lotka–Volterra　commensalism　system　that　incorporates　the　weak　Allee　effect　in　prey　and　symmetric　(equal　harvesting　effort　for　both　species)　non-selective　harvesting,　addressing　a　critical　gap　in　ecological　modeling.　Unlike　previous　work,　we　rigorously　examine　how　the　interaction　between　the　Allee　effect　and　harvesting　disrupts　system　stability,　giving　rise　to　novel　bifurcation　phenomena　and　population　collapse　thresholds.　Using　eigenvalue　analysis　and　the　Dulac–Bendixson　criterion,　we　derive　sufficient　conditions　for　the　existence　and　stability　of　equilibria.　We　find　that　harvesting　destabilizes　the　system　by　inducing　two　saddle-node　bifurcations.　Notably,　prey　abundance　can　increase　with　greater　Allee　intensity　under　controlled　harvesting—a　rare　and　counterintuitive　ecological　outcome.　Moreover,　exceeding　a　critical　harvesting　threshold　drives　both　species　to　extinction,　while　controlled　harvesting　allows　sustainable　coexistence.　Numerical　simulations　support　these　analytical　findings　and　identify　critical　parameter　ranges　for　species　coexistence.　These　results　contribute　to　theoretical　ecology　and　offer　insights　for　designing　sustainable　harvesting　strategies　that　balance　exploitation　with　conservation.　©　2025　by　the　authors.
