Iqembu lamazwe omhlaba labaphenyi bathola ukuthi kungani i-pesticide esuselwa ezithani zokudla ezenziwe nge-safflower kanye namafutha ekotini iyasebenza ngokumelene nezinkulumo ze-spider ezimbili ezihlasela izinkulungwane zezitshalo eziyinkulungwane
Imiphumela yomsebenzi wesayensi oshicilelwe ku-Magazine Engineering eSciences Yempilo, khuluma ngobukhona bendawo enobukhona bemvelo yokubulala izinambuzane okwenziwe ngemvelo.
Izithako zokudla zisetshenzisiwe isikhathi eside njengezinye izindawo zokubulala izinambuzane eziphikisana nezinambuzane zeSegal, njengama-tick, ngoba zivame ukuba yingozi ezincelisayo futhi zingenawo umphumela olimazayo ophelele emvelweni. Ukusebenza kwe-BioPeatides kuvame ukuba khona ngenxa yezindawo ezibonakalayo, hhayi amakhemikhali, - futhi kunciphisa amathuba okuba inkathazo futhi athuthukise ukumelana ne-pesticide, nakho, kunciphisa isidingo sokusebenzisa ama-pesticide noma athuthukisa amasha.
Enye yama-biopeatides anjalo enziwe nge-safflower namafutha ekotini futhi akhiqizwa ngaphansi kophawu lwentengiso lwe-sufreeil linokuphambana okuphezulu ngokumelene nezinambuzane ezidumile - umaki wamaphuzu amabili (iTetranychus urticae), kodwa ngasikhathi sinye uzingela umfo wakho .
I-Web tight ivame ukubonwa ngokusika igobolondo noma "chorion" ngezinsimbi zabo lapho ijikeleza eqandeni. Ukujikeleza, nakho, kusiza ukusika ama-chorion amaningi futhi kusiza ukuqaqelwa. Ithikithi le-mbubro libuye lisebenzise imicu ye-silk ezungeze amaqanda, futhi alukiwe nomzali wakhe ukunamathisela amaqanda ngaphansi kwamaqabunga. Imicu yenza njenge-lever esiza lokhu kujikeleza.
Ukuze uqonde umgomo wokusebenza kwe-biopenateide, ososayensi baphoqa amaqanda esicabucabu bakhokha umuthi futhi wabaphenya ngama-microscopes anamandla, ngokuqhathaniswa namanzi alolayo.
Kutholakale ukuthi i-bioupolitide isemboza ingxenye yamaqanda omkha kasilika omuhle kanye nama-silk. Okubaluleke kakhulu, ukunyakaza okujikelezayo kombungu, okudingekayo ekubambeni, akukho noma kumiswa amaqanda ambozwe nge-biostocide.
Kubukeka sengathi uwoyela ubona amaqanda ngokusebenzisa ama-chorion asikiwe, okwenza ingxenye yangaphakathi ibushelelezi ukujikeleza umbungu, ovimbela ukubopha okufanele.
"I-Bionoyi lisebenza, ukuvimbela ukujikeleza kombungu we-mbubro ngaphakathi kwegobolondo leqanda lokubopha. Ivuselela amandla ama-karns silika futhi yehlisa umphumela wokuqinisa iqanda ebusweni, "kusho uTakeshi Suzuki, i-bionger evela eTokyo University of Agriculture neTechnology (Tuat) kanye nomlobi omkhulu wesifundo.
Imininingwane etholakele ikuvumela ukuthi uchaze ukuthi kungani le bioonoyide ingathinti izisulu zemvelo zemikhakha yewebhu - azisho nje ukuzungeza ukuhanjiswa kusuka kumaqanda.
