Abagadi begadi bafuna izinto ezitshintshiweyo zezitshabalalisi eziqhelekileyo.Abanye banexhala malunga nefuthe lekhemikhali ethile kwimpilo yabo.
Abanye bayatshintsha ngenxa yokuxhalabela iimpembelelo eziyingozi kwihlabathi elibangqongileyo.Kwaba balimi, i-biopesticides inokuba yinto ethambileyo kodwa esebenzayo.
Izibulali-zinambuzane zebhayoloji zikwabizwa ngokuba zizitshabalalisi zendalo okanye zebhayoloji.Ngokuqhelekileyo aziyotyhefu encinci kwizinto ezingajoliswanga kunye nokusingqongileyo.
I-Bacillus thuringiensis kunye ne-Spinosad zimbini ze-biopesticides eziqhelekileyo.Ngokukodwa, zizinambuzane ze-microbial.
Ngokubanzi, iintlobo ze-Bacillus thuringiensis zezona zitshabalalisi ngelixa i-Spinosad ibanzi ngakumbi.
Ziziphi izibulali-zinambuzane?
I-Microbe ligama elifutshane le-microorganisms.Ezi zinambuzane zincinane kangangokuba asinakuzibona ngeliso lenyama.
Kwimeko ye-microbial insecticide, sithetha ngee-microbes ezingenabungozi kubantu, kodwa zibulala izinambuzane.
Isithako esisebenzayo kwi-microbial insecticide yi-microbe ngokwayo.Isenokuba ziintsholongwane, umngundo, iprotozoa, inematode ethwala iintsholongwane, okanye kwanentsholongwane.
I-Bacillus thuringiensis (Bt) ikhona ngokwemvelo emhlabeni, emanzini, nakwimiphezulu yezityalo.ISaccharopolyspora spinosa (Spinosad) ihlala emhlabeni nayo.
Zisebenza njani izitshabalalisi zeMicrobial?
Njengabantu kunye nezityalo zabo zasegadi, izinambuzane zisengozini kwiintsholongwane.Amayeza okubulala izinambuzane asebenzisa ithuba lobu buthathaka.
Ziqulethe i-concentration ephezulu ye-microorganism efunyenwe kwindalo kwaye iyaziwa ngokuchaphazela izinambuzane ezahlukeneyo zezinambuzane.Intsholongwane ihlasela isitshabalalisi.
Ngenxa yoko, isitshabalalisi sigula kakhulu ukuba singaqhubeka sisitya okanye singakwazi ukuzala.
I-Bt ichaphazela isigaba sombungu (umbungu) wamaqela ezinambuzane ezininzi.Xa iimopane, njengeempondo, zitya i-Bt, iqala ukubila emathunjini abo.
Ityhefu eyivelisayo ibangela ukuba le mibungu iyeke ukutya ize ife kwiintsuku ezimbalwa kamva.
Iintlobo ezithile zeBt ezijolise kumaqela athile ezinambuzane ezitshabalalisayo.Bt var.i-kurstaki ijolise kwimibungu (ibhabhathane kunye nemibungu yenundu), umzekelo.
Bt var.I-israelensis ijolise kwimibungu yeempukane, kuquka neengcongconi.Qiniseka ukuba ukhetha uhlobo oluchanekileyo lwe-Bt yesinambuzane sakho.
I-Spinosad sisibulali-zinambuzane esibanzi esibanzi.Ichaphazela imibungu, abasebenzi basemgodini amagqabi, iimpukane, iithrips, ooqongqothwane, kunye namangolwane.
I-Spinosad isebenza ngokuhlasela inkqubo ye-nervous xa izinambuzane ziyityile.Njenge-Bt, izinambuzane ziyeka ukutya kwaye zife emva kweentsuku ezimbalwa.
