Intengo Yemboni I-Methoprene 95% Tc Mosquito Material S I-Methoprene 20% CS Mosquito Larva Killer Larvacide Isibulala-zinambuzane i-CAS 40596-69-8

Incazelo Yomkhiqizo

Kuyisibulala-zinambuzane esisebenza ngamakhemikhali ekilasini lama-hormone ezinambuzane ezincane. I-hormone yezinambuzane ezincane ingalawula ukukhula kwayo, intuthuko, kanye nenqubo yokuguquka kwesimo. Umsebenzi oyinhloko we-hormone yezingane ezincane ukuvimbela ukuguqulwa kwesimo sezibungu ezingakavuthwa, ukugcina izici zesigaba sezinambuzane ezincane, kanye nokuhlala izibungu ngemva kokubola.

I-Methoprene, njengesivikelo samaqabunga kagwayi, kuphazamisa inqubo yokuhlubuka kwezinambuzane. Kungaphazamisa inqubo yokukhula nokukhula kwezimbungulu zikagwayi kanye nezimbobo zempuphu kagwayi, okubangela izinambuzane ezindala ukuba zilahlekelwe amandla azo okuzala, ngaleyo ndlela kulawulwe ngempumelelo ukukhula kwezinambuzane zamaqabunga kagwayi agciniwe.

Isicelo

1. Ukuvimbela nokulawula izinambuzane zempilo. I-Fenpropathrin inomsebenzi omkhulu wokulwa nama-German cockroaches futhi ingabangela ukungabi nabantwana kokubili kwabesifazane nabesilisa abadala. Ukwelapha ngalo muthi njalo kungawuqeda ngenxa yokungazali ngemva kwezinyanga eziyisithupha kuya onyakeni, futhi kusebenza futhi ekulweni nama-cockroaches amakhulu. Ukwenza i-methoprene ekhululayo njalo nakho kuyasebenza ekuvimbeleni nasekwelapheni ama-fleas, omiyane, nezimpukane.

2. Lawula izinambuzane ze-Hemiptera. I-Fenvalerate iyasebenza ekulawuleni ama-aphid aluhlaza okotshani kanye nezimpukane ezimhlophe futhi ibhalisiwe e-United States. Kodwa ukuzinza akukuhle uma kusetshenziswa ensimini. I-Dioxycarb iyasebenza ekulawuleni izimpukane ezimhlophe okotshani kanye nezimpukane ezincane eziluhlaza okotshani.

3. Ukuvimbela nokulawula izinambuzane ezigcinwayo. I-hormone yentsha inomsebenzi omkhulu wokulwa nezinambuzane ze-Lepidoptera ngesikhathi sokugcina, njengokusanhlamvu, ufulawa, nogwayi. E-United States, ihlolwe ukuthi isebenza kahle ekulweni nezinambuzane eziningi ezigcinwayo, njenge-fenpropathrin ne-carbendazim.

4. Ukuvimbela nokulawula izintuthwane. I-fenpropathrin bait ingavimbela ukuguqulwa okuvamile kwezibungu eziyingozi, yenze i-ant king ibe yinyumba, futhi ilawule ngempumelelo izintuthwane zasekhishini. Kukhona nemibiko yokusebenzisa ama-hormone amancane ukwelapha izintuthwane.

5. Khulisa ukukhiqizwa kwesilika. Ukufutha i-hormone yobuntwana noma i-pseudojuvenile hormone njenge-anti juvenile hormone esihlalweni se-silkworm (2-4 micrograms/ekhanda) noma emzimbeni we-5th instar silkworm (1-3 micrograms/ekhanda) kungavimbela ukuguquka kwesimo, kwandise isigaba se-5th instar sezibungu ngaphezu kosuku olulodwa, kwandise ukudla, kwandise usayizi womuntu ngamunye, futhi kwandise ukukhiqizwa kwesilika. Ngokuvamile, kungandisa inani lama-cocoons ayi-10000 cishe ngo-15%.

Ukusebenzisa Izindlela

1. Gcina amaqabunga kagwayi ukuze uvimbele amabhungane kagwayi. Futha u-41% wempuphu encibilikayo izikhathi ezingu-40000 uketshezi ngqo emaqabunga kagwayi. Ukuqinisekisa ukuthi amaqabunga kagwayi ayafuthwa ngendlela efanayo futhi ambozwe ngokuphelele, kungasetshenziswa imishini ekhethekile yokufutha eqondiswe ngezindlela eziningi.

2. Ukuzwela kwezinambuzane kuma-hormone amancane kuyahlukahluka ezigabeni ezahlukene zokukhula nokukhula. Ama-larvae noma ama-nymph azwela kakhulu esigabeni sokugcina, kanti ezinye izigaba azizweli kakhulu. Enkambisweni yokukhula nokukhula kwezinambuzane, kukhethwa isikhathi esifanele bese kusetshenziswa ama-hormone amancane angaphandle ukuphazamisa ibhalansi evamile yama-hormone emzimbeni wezinambuzane, okubangela ukuguquka okungavamile, ukungazali kwabantu abadala, noma ukungakwazi ukuchamisela amaqanda, ngaleyo ndlela kufezwe umgomo wokulawula nokuqeda izinambuzane.

3. I-fenvalerate ye-IC50 yama-Culex pipiens larvae ingu-0.48 micrograms ngelitha, kanti i-fenvalerate ye-ID50 yama-pupae e-wax moth ingu-2.2 micrograms nge-pupa.
