Beauveria bassiana mankhwala othana ndi tizirombo amakupatsani mtendere wamumtima

Beauveria basianandi njira yothanirana ndi tizilombo ndi mabakiteriya. Ndi bowa wochuluka wa tizilombo toyambitsa matenda omwe amatha kuwononga matupi a mitundu yoposa mazana awiri ya tizilombo ndi nthata.

Beauveria bassiana ndi amodzi mwa bowa omwe ali ndi dera lalikulu lomwe amagwiritsidwa ntchitokuwononga tizilombopadziko lonse lapansi. Itha kugwiritsidwa ntchito pothana ndi tizirombo ta Coleoptera ndipo zotsatira zake ndi zabwino kwambiri. Alimi akapopera mankhwala a Beauveria bassiana, njerezo zimakumana ndi tizilombo tomwe timatha kumera pamalo abwino. Beauveria bassiana imamera timachubu tating'ono kwambiri ndikutulutsa poizoni kuti asungunuke khungu la tizilombo. Machubu a Mphukira pang'onopang'ono amalowa m'thupi la tizilombo ndikukula kukhala michere ya mycelium, kupanga matupi ambiri a mycelium, omwe amathanso kuyamwa michere m'madzi am'thupi la tizilombo. Ndi kubereka kwakukulu kwa tizilombo toyambitsa matenda, kagayidwe kake ka tizirombo kadzasokonezeka. Sipanangopita masiku 5 mpaka 7 mutagwiritsa ntchito mankhwalawa kuti tizirombo tiphedwe. Thupi la tizilombo limakhala lolimba ndipo limakutidwa ndi white, downy mycelium. Pambuyo pa masiku awiri, mycelium yotuluka kunja kwa thupi imakula conidia. Izi spores akhoza kufalitsidwa ndi mphepo ndi kupitiriza kupatsira tizilombo, kupanga mliri pakati tizirombo, potero kukwaniritsa zabwino kulamulira tizilombo.

Popeza kuti bowa wouma moyera uli ndi zizindikiro zomwe tazitchula pamwambapa, alimi amathanso kusonkhanitsa mitembo ya tizilombo toyambitsa matenda yomwe inafa chifukwa cha matenda a bowa woyera wouma, kuwaphwanya ndi kuwaza mu ufa kuti agwiritse ntchito. Zotsatira za kuwononga tizilombo ndi zabwino ndithu. Chifukwa chimagwiritsa ntchito mabakiteriya polimbana ndi tizilombo, sichidzawononga chilengedwe. Ngakhale mankhwala ophera tizilombo a Beauveria bassiana atagwiritsidwa ntchito kwa nthawi yayitali, tizirombo sitingakane. Izi ndichifukwa choti matenda a Beauveria bassiana amasankha. Ikhoza kupha tizirombo taulimi monga nsabwe za m'masamba, thrips, ndi nyongolotsi za kabichi, koma sizingawononge tizilombo topindulitsa monga ma ladybugs, lacewings, ndi ntchentche zomwe zimadya nsabwe za m'masamba.

Beauveria bassiana mankhwala ophera tizilombo ndi opanda poizoni, otetezeka komanso okhalitsa. Ikhoza kukwaniritsa cholinga chogwiritsa ntchito nthawi imodzi komanso kupewa nthawi yayitali. Itha kupha tizirombo taulimi popanda kuwononga tizirombo topindulitsa m'minda. Komabe, chifukwa cha kuchepa kwake, sichinavomerezedwe ndi alimi ambiri a masamba. Koma ndikusintha kwazomwe anthu amafuna pazamasamba komanso kufunikira kwazakudya zobiriwira komanso zachilengedwe, Beauveria bassiana idzakhala ndi tsogolo labwino, monga mankhwala ophera tizilombo monga matrine omwe amagwiritsidwa ntchito kwambiri ndi alimi amasamba masiku ano.
