Ingcaciso yeMveliso

Sisibulala-zinambuzane esisebenza ngebhayoloji kwi-hormone yolutsha yezinambuzane. I-hormone yolutsha yezinambuzane inokulawula ukukhula kwayo, uphuhliso, kunye nenkqubo yokutshintsha i-metamorphosis. Umsebenzi ophambili we-hormone yolutsha kukuthintela ukutshintsha kwe-larvae engavuthwanga, ukugcina iimpawu zesigaba solutsha lwezinambuzane, kunye nokuhlala i-larvae emva kokubola.

I-Methoprene, njengesixhobo sokukhusela amagqabi ecuba, iphazamisa inkqubo yokuxobuka kwezinambuzane. Ingaphazamisa inkqubo yokukhula nophuhliso lweencukuthu zecuba kunye neencukuthu ezithwala umgubo wecuba, ibangela ukuba izinambuzane ezindala zilahlekelwe ngamandla azo okuzala, ngaloo ndlela ilawula ngempumelelo ukukhula kwezinambuzane zecuba ezigciniweyo.

Isicelo

1. Ukuthintela nokulawula izinambuzane eziyingozi kwimpilo. I-Fenpropathrin inamandla amakhulu okulwa neempukane zaseJamani kwaye inokubangela ukungazali kubantu abadala abangabasetyhini nabesilisa. Ukunyanga rhoqo ngale mithi kunokuyiphelisa ngenxa yokungazali emva kweenyanga ezintandathu ukuya kunyaka, kwaye iyasebenza nakwiimpukane ezinkulu. Ukwenza i-methoprene ekhupha rhoqo i-arhente ye-methoprene ikwasebenza ekuthinteleni nasekunyangeni iimpukane, iingcongconi kunye neempukane.

2. Lawula izinambuzane zeHemiptera. I-Fenvalerate iyasebenza ekulawuleni ii-aphids zegreenhouse kunye neempukane ezimhlophe kwaye ibhalisiwe eMelika. Kodwa uzinzo alukho kakuhle xa isetyenziswa entsimini. I-Dioxycarb iyasebenza ekulawuleni iimpukane ezimhlophe zegreenhouse kunye neecrustaceans.

3. Ukuthintela nokulawula izinambuzane ezigcinwayo. Le hormone intsha inomsebenzi omkhulu wokulwa nezinambuzane ezihlala kwiLepidoptera ngexesha lokugcinwa kwayo, ezifana neenkozo, umgubo, kunye necuba. E-United States, ivavanyiwe ukuba iyasebenza kwizinambuzane ezininzi ezigcinwayo, ezifana ne-fenpropathrin kunye ne-carbendazim.

4. Ukuthintela nokulawula iimbovane. I-Fenpropathrin bait inokuthintela utshintsho oluqhelekileyo lwezibungu eziyingozi, yenze i-ant king ingabi nazintsholongwane, kwaye ilawule ngokufanelekileyo iimbovane zasekhitshini. Kukwakho neengxelo zokusebenzisa iihomoni ezincinci ukunyanga ii-termites.

5. Yandisa imveliso yesilika. Ukutshiza i-juvenile hormone okanye i-pseudojuvenile hormone efana ne-anti juvenile hormone kwisihlalo se-silkworm (2-4 micrograms/entloko) okanye kwi-5th instar silkworm body (1-3 micrograms/entloko) kunokuthintela utshintsho, kwandise inqanaba le-5th instar larval ngaphezu kosuku olunye, kwandise ukutya, kwandise ubungakanani bomntu ngamnye, kwaye kwandise imveliso yesilika. Ngokubanzi, inokunyusa inani le-10000 cocoons malunga ne-15%.

Ukusebenzisa Iindlela

1. Gcina amagqabi ecuba ukuze uthintele iincukuthu zecuba. Futha umgubo onyibilikayo oyi-41% izihlandlo ezingama-40000 ulwelo ngqo kumagqabi ecuba. Ukuqinisekisa ukuba amagqabi ecuba ayatshizwa ngokulinganayo kwaye agqunywe ngokupheleleyo, kungasetyenziswa izixhobo zokutshiza ezinomthamo omninzi okanye izixhobo zokutshiza ezinomthamo ophantsi kakhulu.

2. Uvakalelo lwezinambuzane kwiihomoni eziselula luyahluka kumanqanaba ahlukeneyo okukhula nophuhliso. Iingqakumba okanye iinymph zinovakalelo olukhulu kwinqanaba lokugqibela, ngelixa ezinye izigaba zinovakalelo oluncinci. Kwinkqubo yokukhula nophuhliso lwezinambuzane, kukhethwa ixesha elifanelekileyo kwaye iihomoni eziselula zangaphandle zisetyenziselwa ukuphazamisa ibhalansi yehomoni eqhelekileyo emzimbeni wezinambuzane, okubangela utshintsho olungaqhelekanga, ukungazali kwabantu abadala, okanye ukungakwazi ukuqandusela amaqanda, ngaloo ndlela kufezekiswa injongo yokulawula nokuphelisa izinambuzane.

3. I-IC50 fenvalerate yeCulex pipiens larvae yi-0.48 micrograms ngelitha, kwaye i-ID50 fenvalerate ye-wax moth pupae yi-2.2 micrograms nge-pupa.
