Zeziphi izinambuzane ezinokuthi zilawulwe yiChlorbenzuron?

I-Chlorbenzuronsisithinteli sokwenziwa kwe-chitin yohlobo lwe-benzoylurea. Sinemisebenzi kunye nokusebenza oku kulandelayo:

1. Indlela yokusebenza:

Ngokuthintela umsebenzi we-chitin synthase ye-cuticle yezinambuzane kunye ne-uridine diphosphate coenzyme, ithintela ukwenziwa kwe-chitin kwizinambuzane. I-Chitin yinxalenye ebalulekileyo ye-cuticle yezinambuzane. Ukungabikho kwe-chitin kuya kuthintela ukwakheka kwe-cuticle entsha kwi-larvae, okubangela ukuba izinambuzane zingakwazi ukubola ngendlela eqhelekileyo kwaye ekugqibeleni zife ngenxa yokungaphumeleli ukugqiba inkqubo yokukhula nophuhliso eqhelekileyo.

Ichaphazela imetabolism yokuphefumla kwamaqanda kunye nemetabolism ye-DNA kunye neproteni ngexesha lenkqubo yophuhliso lwe-embryonic, nto leyo ebangela ukuba iimbungu ezingaphakathi kwamaqanda zingabi na-chitin kwaye ngaloo ndlela zingaqanduseli okanye zife kwangoko emva kokuqanduselwa.

2. Iimpawu zesenzo:

Ikakhulu ubuthi besisu: Xa izinambuzane zisitya ukutya okuneChlorbenzuron, isibulali-zinambuzane sisebenza emizimbeni yazo. Nangona sikwanomphumo wokubulala abantu abadibanayo, asinawo amandla okufunxa umzimba.

Ukukhetha okuphezulu: Inamandla aphezulu okubulala izinambuzane ngokuchasene nezinambuzane ezibolayo, ingakumbi izinambuzane ze-lepidopteran, kodwa ayinabungozi kangako kwizinambuzane eziluncedo kunye neenyosi zosapho lwe-hymenoptera kunye neentaka zasehlathini (nangona inempembelelo kwi-ladybeetles).

Ixesha elide lokusebenza: Izinga lokuwohloka kweChlorbenzuron licotha, liyamelana nokukhukuliseka kwemvula, kwaye linokugcina ukusebenza okuhlala ixesha elide kwindalo esingqongileyo. Ngokubanzi, ixesha lokusebenza linokufikelela kwiintsuku ezili-15 ukuya kwezingama-20.

3. Izinambuzane ezijoliswe kuzo:

Isebenza kakhulu kwizinambuzane ezahlukeneyo ze-lepidopteran, ezifana ne-peach tree leafminer, i-tea black moth, i-tea eelworm, i-cabbage caterpillar, i-rape night moth, i-wheat stickworm, i-corn borer, i-American white moth, i-pine caterpillar, i-dancing moth, i-boat moth, kunye ne-treetop moth.

Ukutshiza ingxube ethile yesisombululo se-methomyl kwiingcambu zemifuno yetswele negalikhi kunokubulala ngokufanelekileyo amagcuntswana omhlaba; kukwanefuthe elihle ekulawuleni izibungu zeempukane ezindlini zangasese kunye neengcongconi ezikwiidama zamanzi ezimileyo.

4. Ukusebenza kakuhle: Isiphumo sale chiza sibonakala kancinci kancinci emva kweentsuku ezi-3 ukuya kwezi-5 emva kokusetyenziswa, kwaye incopho yokufa iyenzeka malunga neentsuku ezi-7.

Xa usebenzisa iChlorbenzuron, kuyimfuneko ukukhetha ixesha elifanelekileyo lokufaka (ngesiphumo esihle ngexesha lesigaba se-larval), sebenzisa indlela echanekileyo kunye noxinzelelo, kwaye uphephe ukuxubana nezinto ze-alkaline. Ukongeza, ukusetyenziswa kweChlorbenzuron kubonisa neengenelo zayo zokusingqongileyo. Njengesibulali-zinambuzane esinengqondo ngokwebhayoloji, iChlorbenzuron inokulawula inani lezinambuzane ngelixa inempembelelo encinci embi kwindalo esingqongileyo. Ayichaphazeli ulwakhiwo lweentsholongwane zomhlaba, ayiqokeleli emanzini, kwaye inetyhefu ephantsi kakhulu kwizinto eziphilayo ezingajoliswanga njengeentlanzi kunye nezilwanyana zasemanzini ezingenamqolo, nto leyo enceda ekugcineni ulungelelwaniso lwendalo. Ke ngoko, ekukhuthazeni ezolimo eziluhlaza kunye neengcamango zophuhliso oluzinzileyo namhlanje, iChlorbenzuron ibe lukhetho olubalulekileyo lokulawula izinambuzane kwiindawo ezininzi.

Ukuze kuphuculwe ngakumbi isiphumo sokusebenzisa iChlorbenzuron, izazinzulu zihlala zihlola imiphumo yayo yokusebenzisana nezinye izibulali-zinambuzane okanye iindlela zokulawula izinto eziphilayo. Umzekelo, ukudibanisa iChlorbenzuron neepheromones zesini kunokuphazamisana nokuziphatha kokudibana kwezinambuzane, ngaloo ndlela kunciphisa ngempumelelo izinga lokuzala kwezinambuzane; okanye ukuyidibanisa neearhente zokulawula izinto eziphilayo ezifana neebhaktheriya kunye neefungi ukwenza indlela yolawulo yamanqanaba amaninzi, nto leyo ephucula isiphumo solawulo ngokubanzi.

Kwangaxeshanye, ngokuqhubela phambili kwetekhnoloji, ukuvela kweenkqubo zokutshiza ezikrelekrele kwenze ukuba kube nokwenzeka ukusetyenziswa ngokuchanekileyo kwe-methomyl. Ngezixhobo zezolimo zanamhlanje ezifana needrone kunye nezitshiza ezikrelekrele, indawo yokufaka isicelo, ixesha kunye nomthamo wokutshiza kunokulawulwa ngokuchanekileyo, kuncitshiswe inkunkuma yezibulali-zinambuzane, kuphuculwe ukusebenza kakuhle kolawulo, kwaye kuqinisekiswe ngakumbi ukhuseleko lweemveliso zezolimo kunye nomgangatho wokusingqongileyo.

Ukuqukumbela, iChlorbenzuron, njengomthinteli wokwenziwa kwe-benzoylurea chitin osebenzayo, ongenabungozi kangako kwaye onobuhlobo nokusingqongileyo, idlala indima ebalulekileyo ekulawuleni izinambuzane kwezolimo. Ngokukhula kophando kunye nophuhliso lwetekhnoloji, amathuba okusetyenziswa kwayo aya kuba maninzi nangakumbi, anegalelo kuphuhliso oluzinzileyo lwezolimo.
