I-Beauveria bassianaindlela yokulawula izinambuzane ngamagciwane. Iwukhunta olubanzi lwezinambuzane olungahlasela imizimba yezinhlobo ezingaphezu kwamakhulu amabili zezinambuzane nezibungu.
I-Beauveria bassiana ingenye yesikhunta esinendawo enkulu kunazo zonke esetshenziselwaukulawula izinambuzaneemhlabeni wonke. Ingasetshenziselwa ukubhekana nezinambuzane ze-Coleoptera futhi umphumela nawo muhle kakhulu. Ngemva kokuba abalimi befafaze lesi senzo se-Beauveria bassiana, izinhlamvu zizohlangana nengaphezulu lesinambuzane, lizivumele ukuthi ziqhume ngaphansi kwezimo ezifanele. I-Beauveria bassiana izokhula amashubhu amancane kakhulu futhi ikhiphe ubuthi ukuze incibilikise isikhumba sesinambuzane. Ama-bud tubes angena kancane kancane emzimbeni wesinambuzane futhi akhule abe i-mycelium enomsoco, akhe inani elikhulu lemizimba ye-mycelium, engakwazi futhi ukumunca ngokuqondile umsoco oketshezini lomzimba wesinambuzane. Ngokukhiqizwa okukhulu kwe-pathogen, i-metabolism ezinambuzaneni izophazamiseka. Ngeke kuze kube yizinsuku ezi-5 kuya kweziyi-7 ngemva kokufakwa kwesibulala-zinambuzane lapho izinambuzane zizobulawa khona. Umzimba wezinambuzane kancane kancane uba lukhuni futhi umbozwe i-mycelium emhlophe, ephansi. Ngemva kwezinsuku ezimbili, i-mycelium ephumela ngaphandle komzimba ikhula i-conidia eminingi. Lezi zinhlamvu zingasakazwa ngumoya futhi ziqhubeke nokuthelela izinambuzane, zenze ubhubhane phakathi kwezinambuzane, ngaleyo ndlela zithole umphumela omuhle ekulawuleni izinambuzane.
Njengoba isikhunta esimhlophe esiqinisayo sinezici ezishiwo ngenhla, abalimi bangakwazi futhi ukuqoqa izidumbu zezinambuzane ezifile ngenxa yokutheleleka kwesikhunta esiqinisayo esimhlophe, basichoboze bese sifafaza zibe yimpushana ukuze zisetshenziswe. Umphumela wokulawula izinambuzane nawo muhle impela. Ngenxa yokuthi isebenzisa amagciwane ukuze ilawule izinambuzane, ngeke ingcolise imvelo. Ngisho noma izibulala-zinambuzane ze-Beauveria bassiana zisetshenziswa isikhathi eside, izinambuzane ngeke zikwazi ukumelana. Lokhu kungenxa yokuthi ukutheleleka kwe-Beauveria bassiana kuyakhetha. Ingazibulala ngokukhetha izinambuzane zezolimo ezifana nezintwala, amathrips, nezibungu zeklabishi, kodwa ngeke idale umonakalo ezinambuzaneni eziwusizo njengama-ladybugs, ama-lacewings, nezibawu ezidla ama-aphid.
Isibulala-zinambuzane i-Beauveria bassiana asinabuthi, siphephile futhi sihlala isikhathi eside. Ingakwazi ukufeza injongo yokusetshenziswa kwesikhathi esisodwa kanye nokuvimbela isikhathi eside. Ingabulala izinambuzane zezolimo ngaphandle kokulimaza izinambuzane ezinenzuzo emapulazini. Nokho, ngenxa yomphumela wayo ohamba kancane, ayikamukelwa iningi labalimi bemifino. Kodwa ngokuthuthukiswa kwezidingo zabantu zekhwalithi yemifino kanye nesidingo esikhulayo sokudla okuluhlaza kanye nemvelo, i-Beauveria bassiana izoba nekusasa elithembisayo, njengama-biopesticides afana ne-matrine asetshenziswa kakhulu abalimi bemifino namuhla.
