I-Chlorbenzuroniyisivimbeli sokwenziwa kwe-chitin yohlobo lwe-benzoylurea. Inemisebenzi kanye nokusebenza okulandelayo:
1. Indlela yokusebenza:
Ngokuvimbela umsebenzi we-chitin synthase yezinambuzane kanye ne-uridine diphosphate coenzyme, kuvimbela ukwakheka kwe-chitin ezinambuzaneni. I-Chitin iyisici esibalulekile se-cuticle yezinambuzane. Ukuntuleka kwe-chitin kuzovimbela ukwakheka kwe-cuticle entsha ezibungwini, okubangela ukuthi izinambuzane zingakwazi ukubola ngendlela evamile futhi ekugcineni zife ngenxa yokwehluleka ukuqeda inqubo evamile yokukhula nokuthuthukiswa.
Kuthinta indlela yokuphefumula kwamaqanda kanye ne-DNA kanye ne-protein metabolism ngesikhathi senqubo yokukhula kombungu, okubangela ukuthi izibungu ezingaphakathi kwamaqanda zithole i-chitin futhi ngaleyo ndlela zihluleke ukuchamisela noma zife ngokushesha ngemva kokuchamisela.
2. Izici zesenzo:
Ubuthi besisu ikakhulukazi: Uma izinambuzane zidla ukudla okuqukethe i-Chlorbenzuron, isibulala-zinambuzane sisebenza emizimbeni yazo. Nakuba futhi sinomphumela wokubulala ukuthintana, asinawo amandla okumunca umzimba.
Ukukhetha okuphezulu: Inomsebenzi omkhulu wokubulala izinambuzane ngokumelene nezinambuzane ezibolayo, ikakhulukazi izinambuzane ze-lepidopteran, kodwa ayinawo umonakalo ezinambuzaneni ezizuzisayo nasezinyosini zomndeni we-hymenoptera kanye nezinyoni zasehlathini (yize inomthelela kuma-ladybeetles).
Isikhathi eside sokusebenza: Izinga lokuwohloka kwe-Chlorbenzuron lihamba kancane, liyamelana nokuguguleka kwemvula, futhi lingagcina ukusebenza kahle okuhlala isikhathi eside emvelweni. Ngokuvamile, isikhathi sokusebenza singafinyelela ezinsukwini eziyi-15 - 20.
3. Izinambuzane eziqondiwe:
Isebenza kahle kakhulu ekulweni nezinambuzane ezahlukahlukene ze-lepidopteran, njenge-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, kanye ne-treetop moth.
Ukufutha ingxube ethile yesisombululo se-methomyl ezimpandeni zemifino ka-anyanisi negalikhi kungabulala ngempumelelo izikelemu zomhlabathi; futhi kunomphumela omuhle ekulawuleni izibungu zezimpukane ezindlini zangasese kanye nomiyane emachibini amanzi amile.
4. Ukusebenza Kahle: Umphumela womuthi ubonakala kancane kancane ezinsukwini ezi-3 kuya kwezi-5 ngemva kokusetshenziswa, futhi inani eliphakeme lokufa livela cishe ezinsukwini ezi-7.
Uma usebenzisa i-Chlorbenzuron, kubalulekile ukukhetha isikhathi esifanele sokusetshenziswa (ngomphumela omuhle kakhulu ngesikhathi sesigaba sama-larval), sebenzisa indlela efanele kanye nokuhlushwa, futhi ugweme ukuxubana nezinto ze-alkaline. Ngaphezu kwalokho, ukusetshenziswa kwe-Chlorbenzuron kubonisa nezinzuzo zayo zemvelo. Njengesibulala-zinambuzane esinengqondo ngokwezinto eziphilayo, i-Chlorbenzuron ingalawula inani lezinambuzane ngenkathi inomthelela omncane omubi emvelweni. Ayithinti isakhiwo sezinambuzane zomhlabathi, ayiqongelelani emanzini, futhi inobuthi obuphansi kakhulu ezintweni eziphilayo ezingahlosiwe njengezinhlanzi nezilwane zasemanzini ezingenamgogodla, okusiza ekugcineni ibhalansi yemvelo. Ngakho-ke, ekukhuthazeni ezolimo eziluhlaza kanye nemibono yentuthuko esimeme namuhla, i-Chlorbenzuron isibe yisinqumo esibalulekile sokulawula izinambuzane ezindaweni eziningi.
Ukuze kuthuthukiswe umphumela wokusetshenziswa kwe-Chlorbenzuron, ososayensi bahlala behlola imiphumela yayo yokusebenzisana nezinye izibulala-zinambuzane noma izindlela zokulawula izinto eziphilayo. Isibonelo, ukuhlanganisa i-Chlorbenzuron nama-pheromone obulili kungaphazamisa ukuziphatha kokuhlangana kwezinambuzane, ngaleyo ndlela kunciphise ngempumelelo izinga lokuzala kwezinambuzane; noma ukuyihlanganisa nama-ejenti okulawula izinto eziphilayo afana namabhaktheriya nesikhunta ukuze kwakheke indlela yokulawula enamazinga amaningi, kuthuthukiswe umphumela wokulawula jikelele.
Ngesikhathi esifanayo, ngokuthuthuka kobuchwepheshe, ukuvela kwezinhlelo zokufafaza ezihlakaniphile kwenze kwaba nokwenzeka ukusetshenziswa kwe-methomyl ngokunembile. Ngemishini yezolimo yesimanje efana nama-drone kanye nezifutho ezihlakaniphile, indawo yokufaka, isikhathi kanye nomthamo wokufafaza kungalawulwa ngokunembile, kuncishiswe imfucuza yezibulala-zinambuzane, kuthuthukiswe ukusebenza kahle kokulawula, futhi kuqinisekiswe ngokuqhubekayo ukuphepha kwemikhiqizo yezolimo kanye nekhwalithi yemvelo.
Ekuphetheni, i-Chlorbenzuron, njenge-benzoylurea chitin synthesis inhibitor esebenza kahle, engenabuthi futhi enobungani nemvelo, idlala indima ebalulekile ekulawulweni kwezinambuzane kwezolimo. Ngokujula kocwaningo kanye nokusungula izinto ezintsha kwezobuchwepheshe, amathuba okusetshenziswa kwayo azoba maningi nakakhulu, anikele ekuthuthukisweni okusimeme kwezolimo.
