1.Pyrethrine ni ibikoresho by'ibanze byo gutegura imibavu y’imibu, kandi ni ibintu byica udukoko twica udukoko turimo pyrethrum, ibyatsi bimera mu muryango wa Asteraceae.Hariho pyrethrine I na pyrethrin II, kandi hariho na guaifenesin I na guaifenesin II zifite imiterere isa nubunini bwa Chemical Book.Kugeza ubu, ibice bitandukanye bisa na pyrethroide karemano byashizwe hamwe kandi bikoreshwa nkudukoko twica udukoko, hamwe bizwi nka pyrethroide.

2.Pyrethrine ni ibimera byindabyo za chrysanthemum zumye kandi zikoreshwa cyane nkudukoko twica udukoko kuko tuba duhagaze neza mugihe cy'ubushyuhe n'umucyo.Shampo zimwe zica ibisebe byumutwe nazo zirimo pyrethrine.Pyrethroide ikomatanyirizwa hamwe hashingiwe kumiterere ya pyrethroide nibikorwa byibinyabuzima, kandi ituze ryabo ryiyongereye.Bagabanijwe cyane mubwoko bwa I nubwoko bwa II, kandi ubwoko bwa II ni uburozi kurenza ubwoko bwa I. Imiti ya sintetike pyrethroide ikoreshwa cyane mubuhinzi ndetse n’ubuhinzi bw’imboga mu kwica udukoko twubaka (nka terite), inyo na flas.Pyrethroide na pyrethroide ya syntetique irashobora kwinjira vuba mubyonnyi no kubihagarika.Permethrin ni ubushakashatsi bwakozwe hakiri kare pyrethroid yica udukoko tutarimo imiterere ya cyano, kandi yari iyambere mu miti yica udukoko twitwa pyrethroid yagaragaye nkudukoko twangiza udukoko twangiza udukoko twangiza ubuhinzi.

3.Pyrethrum (izina ry'ubumenyi: Pyrethrum cinerariifolium Trev.) Ni umwe mu bagize umuryango wa Compositae.Kavukire i Burayi.Shaanxi, Shandong, Heilongjiang, Jilin, Liaoning, Jiangsu, Zhejiang, Anhui, Jiangxi, Hunan, Sichuan, Guangdong na Yunnan byose bihingwa mu Bushinwa.
Pyrethrum irimo 0,6-1.3% ya pyrethrin na grimethrine mu ndabyo zayo.Pyrethrin, izwi kandi ku izina rya pyrethrin, ni amavuta meza y'amavuta akunze gukoreshwa nk'udukoko.

Gusaba

1.Pyrethide ni imiti yagutse yica udukoko ishobora kurwanya udukoko dutandukanye.Indwara ya virusi yica udukoko iruta inshuro 10 kugeza ku 100 kurenza iy'ibihe byakera byica udukoko nka chlorine kama, fosifore kama na karbamate.Uburyo bwibikorwa byayo ni uguhungabanya physiologiya isanzwe yimitsi y’udukoko, bigatuma bapfa bazize umunezero, ubumuga nubumuga.Pyrethroide ifite umutekano ku bantu no ku nyamaswa bitewe na dosiye nkeya hamwe n’ubushakashatsi buke, kandi bifite ibidukikije bike.

2.Pyrethroide irashobora gutera depolarisiyasi yoroheje ya selile ya selile mu binyabuzima, kongera ibice nyuma yubushobozi, biganisha ku gusubiramo nyuma yo gusohoka, bigira ingaruka kumiyoboro ya Na + na K +, guhagarika moteri yumuriro wa moteri ya Chemical Book kandi bigatera uburozi bwimisatsi.Imbaraga za Pyrethroid zirashobora kubuza no gutinza metabolisme ya pyrethroide mumubiri, bikongera uburozi bwabyo kandi bikongerera igihe ibiyobyabwenge mumubiri kugirango byongere imbaraga.
