Iintsalela zezibulali-zinambuzane ekutyeni: injani imeko kwi-EU?
Kwingxelo yayo yonyaka yamva nje, i-European Food Safety Authority (EFSA) ithe umngcipheko kwimpilo yabantu ovela kwiintsalela zezibulali-zinambuzane ezisetyenziselwa ukubulala okanye ukulawula izinambuzane (kuquka izidalwa ezithwala izifo kunye nezinambuzane eziyingozi, izilwanyana kunye nezityalo) usaphantsi, ngokuhambelana neminyaka edlulileyo. I-EFSA ihlalutye ...Funda ngokugqithisileyo -
Khawubone impembelelo yezibulali-zinambuzane kumsebenzi wetshaneli ye-TRP kunye nokuhlanganiswa kwayo kwizinambuzane.
Izibulali-zinambuzane zidlala indima ebalulekileyo ekusombululeni ukunqongophala kokutya kwihlabathi liphela nasekulweni nezifo zabantu ezithwalwa zizilwanyana. Nangona kunjalo, ingxaki ekhulayo yokuxhathisa izibulali-zinambuzane ifuna ngokungxamisekileyo ukufunyanwa kweekhompawundi ezintsha ezijolise kwiithagethi ezingasetyenziswanga ngokwaneleyo. I-Insect transient receptor potential (TRPV) ...Funda ngokugqithisileyo -

Ifungi ebangela izifo zezinambuzane iBeauveria bassiana kunye neMetarhizium anisopliae zidlala indima ekukhuthazeni ukukhula kombona (iiZea mays).
I-Beauveria bassiana kunye ne-Metarhizium anisopliae zezona fungi zibalulekileyo nezisetyenziswa kakhulu ekulawuleni izinambuzane. Izifundo zakutshanje zibonise ukuba zinokukhuthaza ukukhula kwezityalo emva kokugonyelwa okwenziweyo. Ukuvavanya ngokuchanekileyo ukuhlanganiswa kwezityalo kunye nokukhula kwazo...Funda ngokugqithisileyo -
Iingxowa zelaphu ezinyangiweyo ngezibulali-zinambuzane 'ezingabizi kakhulu' zinokunciphisa imalariya kwiintsana | Impilo Yehlabathi
Uphando lubonise ukuba ngenxa yokuba ukulunywa ziingcongconi kwenzeka rhoqo emini, ukumanzisa amalaphu anezixovuli zezinambuzane eziqhelekileyo yindlela elula nesebenzayo. Ukusuka eAfrika ukuya eLatin America, uze uye eAsia, kangangeenkulungwane oomama bebesonga iintsana zabo ngelaphu baze bathwale...Funda ngokugqithisileyo -
Izinto eziphambili ezibangela ubuthi be-phytotoxicity
I. Izityalo Izityalo ezahlukeneyo zibonisa amanqanaba ahlukeneyo okuxhathisa kunye nobuthathaka kuhlobo ngalunye lwezinambuzane. Izityalo zinenqanaba elithile lokunyamezela izibulali zinambuzane. Xa uxinzelelo okanye idosi idlule umda othile, ngokubanzi ziya kujongana namanqanaba ahlukeneyo omonakalo ovela kwizinambuzane. ...Funda ngokugqithisileyo -
Iimpawu eziphambili kunye neendlela zokusebenzisa iChlorantraniliprole
I. Iipropati eziphambili zeChlorantraniliprole Le nkunkuma yokubulala izinambuzane yi-nicotinic receptor activator (yezihlunu). Ivuselela ii-receptor ze-nicotinic kwizinambuzane, ibangela ukuba imijelo ye-receptor ihlale ivulekile ngendlela engaqhelekanga ixesha elide, nto leyo ekhokelela ekukhutshweni okungenamkhawulo kwee-calcium ions ezigcinwe ngaphakathi...Funda ngokugqithisileyo -
