I-Beauveria bassianakuyindlela yokulawula izinambuzane ezinamabhaktheriya. Kuyisikhunta esibangela izifo ezinambuzaneni eziningi esingahlasela imizimba yezinhlobo ezingaphezu kwamakhulu amabili zezinambuzane nezibungu.
I-Beauveria bassiana ingenye yefungi enendawo enkulu kunazo zonke esetshenziselwaukulawulwa kwezinambuzaneemhlabeni jikelele. Ingasetshenziswa ukubhekana nezinambuzane zaseColeoptera futhi umphumela nawo muhle kakhulu. Ngemva kokuba abalimi sebefafaze lesi sidakamizwa saseBeauveria bassiana, ama-spores azohlangana nobuso besinambuzane, esivumela ukuba sikhule ngaphansi kwezimo ezifanele. I-Beauveria bassiana izokhula amashubhu amancane kakhulu amahlumela futhi ikhiphe ubuthi bokuncibilikisa isikhumba sesinambuzane. Amashubhu amahlumela kancane kancane angena emzimbeni wesinambuzane futhi akhule abe yi-mycelium yezakhamzimba, akha inani elikhulu lemizimba ye-mycelium, engamunca ngqo izakhamzimba eziketshezini zomzimba wesinambuzane. Ngokuzalana okukhulu kwegciwane, ukusebenza kwe-metabolism ezinambuzaneni kuzophazamiseka. Kuze kube yizinsuku ezi-5 kuya kweziyi-7 ngemuva kokusetshenziswa kwesibulala-zinambuzane lapho izinambuzane zizobulawa khona. Umzimba wesinambuzane uba lukhuni kancane kancane futhi umbozwe yi-mycelium emhlophe, ephansi. Ngemva kwezinsuku ezimbili, i-mycelium enwebeka ngaphandle komzimba ikhula ama-conidia amaningi. Lawa ma-spores angasakazwa umoya futhi aqhubeke nokuthelela isinambuzane, akha ubhubhane phakathi kwezinambuzane, ngaleyo ndlela kufezwe umphumela omuhle ekulawulweni kwezinambuzane.
Njengoba isikhunta esimhlophe esiqinisayo sinezimpawu ezishiwo ngenhla, abalimi bangaqoqa nezidumbu zezinambuzane ezifile ngenxa yokutheleleka kwesikhunta esimhlophe esiqinisayo, bazichoboze bese bezifutha zibe yimpuphu ukuze zisetshenziswe. Umphumela wokulawula izinambuzane nawo muhle impela. Ngoba isebenzisa amagciwane ukulawula izinambuzane, ngeke ingcolise imvelo. Ngisho noma izibulala-zinambuzane zaseBeauveria bassiana zisetshenziswa isikhathi eside, izinambuzane ngeke zikhule ukumelana nazo. Lokhu kungenxa yokuthi ukutheleleka kweBeauveria bassiana kuyakhetha. Kungabulala ngokukhethekile izinambuzane zezolimo ezifana nama-aphid, ama-thrips, kanye nezibungu zeklabishi, kodwa ngeke kubangele umonakalo ezinambuzaneni ezizuzisayo ezifana nama-ladybugs, ama-lacewings, kanye nezimpukane ezidla ama-aphid.
Isibulala-zinambuzane saseBeauveria bassiana asiyona into enobuthi, siphephile futhi sihlala isikhathi eside. Singafeza injongo yokusetshenziswa kanye kanye nokuvimbela isikhathi eside. Singabulala izinambuzane zezolimo ngaphandle kokulimaza izinambuzane ezizuzisayo ezindaweni zokulima. Kodwa-ke, ngenxa yomphumela waso ohamba kancane, asikamukelwa iningi labalimi bemifino. Kodwa ngokuthuthukiswa kwezidingo zabantu zekhwalithi yemifino kanye nesidingo esikhulayo sokudla okuluhlaza nokungokwemvelo, iBeauveria bassiana izoba nekusasa elithembisayo, njengemithi yokubulala izinambuzane efana ne-matrine esetshenziswa kakhulu ngabalimi bemifino kulezi zinsuku.
