Kufunikira kwa fipronil
Mu agalu ndi amphaka, Fipronil amagwiritsidwa ntchito monga malo oyambilira akugwira bwino ntchito motsutsana ndi utoto ndi mitundu ingapo. Koma osati kwa mafupa onse ndi nsabwe zamtundu wa nsabwe zomwe zingafanane ndi agalu ndi amphaka. Kuthana ndi thaluti ndikofanana ndi zidutswa zina za tizilombo toyambitsa matenda monga imidacloprid, pyroprole, spintosad kapena spinnosad. Kukula kwa chitukuko cha tizilombo (mwachitsanzo methoprene, pyriproxyfen) nthawi zambiri amawonjezeredwa ndi mawonekedwe omwe akupanga magawo a utoto womwe umakupangitsani kunyama zam'munda.
Mu Livistock Fipronil ndi yosagwiritsidwa ntchito motsutsana ndi nkhupakupa nkhupakupa (ma mainga a Boophlulus) ndi nyanga (Hematobia Suntul). Ndi njira ina yotchuka kwambiri m'madera omwe majeremutu awiri ofunikira apanga kukana kwambiri pyrethroids ndi erctophosphates.
Pharmacokinetics of Fipronil
Fipronil ndi lipophilic ndipo ikagwiritsidwa ntchito kwambiri kwa nyama zimayikidwa mu sebaceous wa khungu, kuchokera komwe amamasulidwa pang'onopang'ono. Izi zimathandiza kuti zikhale zosakanika kwanthawi yayitali ku majeremusi angapo akunja, mwachitsanzo atcheru ndi nkhupakupa.
Mayamwidwe a Fipronil omwe amaperekedwa kwambiri ndi otsika kwambiri kwa agalu ndi amphaka, nthawi zambiri osapitilira 5% ya mlingo wovomerezeka. Fipronil yopepuka imapezeka makamaka m'mafuta onenepa. The metabolite ndi sulfane wochokera ku sulfone, womwe ndi woopsa kwambiri, zonse za majeremusi komanso zinyama.
Kuchulukitsa kwa fipronil yoyamwa kumachitika makamaka kudzera ndowe. Poyatsira nyama mpaka 5% ya mlingo woyamwa amatha kufutulidwa mkaka.
