Qhov txawv ntawm Cyromazine thiab myimethamine

I. Cov khoom tseem ceeb ntawmCypromazine

Hauv cov nqe lus ntawm kev ua haujlwm:

Cypromazine yog ib qho tshuajtus tswj kev loj hlobntawm 1,3, 5-triazinekabNws muaj cov haujlwm tshwj xeeb rau cov kab diptera thiab muaj cov nyhuv endosorption thiab conduction, ua rau cov kab diptera thiab pupae raug kev cuam tshuam morphological, thiab cov neeg laus tsis tiav lossis inhibited. Piv txwv li, nrog 1g / L soaking lossis txau, tuaj yeem tiv thaiv Lucilia sericata ntawm yaj; Thaum ntxiv rau hauv cov zaub mov qaib, cov kab ya ntawm cov quav qaib tuaj yeem tiv thaiv thiab kho hauv zos qhov twg cov yoov yug me nyuam. Nws muaj kev txwv zoo thiab tua cov kab ya (piv txwv li cov kab ya maggots) uas loj hlob hauv cov quav; Kev tswj cov nplooj miner yoov ntawm cov nroj tsuag thiab zaub, tshwj xeeb tshaj yog South American nplooj miner yoov, yog cov tshuaj zoo tshaj plaws hauv ntiaj teb. Nws feem ntau inhibits kev tsim ntawm chitin thiab dihydrofolate reductase, tiv thaiv kev thim rov qab, qeeb lub sijhawm loj hlob ntawm cov kab larva, cuam tshuam rau cov txheej txheem molting thiab tiv thaiv kev yug me nyuam ib txwm muaj, ua rau cov kab tuag. Nws kuj tseem tuaj yeem txo cov ntsiab lus ammonia hauv tsev tsiaj thiab txhim kho cov tsiaj txhu thiab nqaij qaib yug me nyuam zoo heev. Nws cov khoom xyaw nquag tuaj yeem lwj hauv av, tsis muaj kuab paug rau ib puag ncig, yog tus neeg sawv cev tiv thaiv ib puag ncig zoo 56.

2, Cov khoom yooj yim ntawm myithramine

Hauv cov nqe lus ntawm kev ua haujlwm:

Ua ib yam khoom siv tswj kev loj hlob ntawm cov kab, nws tuaj yeem ua rau cov kab diptera larvae thiab pupae tsis zoo thaum lub sijhawm loj hlob, thiab tiv thaiv lossis tsis tiav cov kab laus. Tsis muaj kev phom sij rau cov kab laus hauv qhov ncauj lossis hauv zos, tab sis qhov ceev ntawm cov qe raug txo qis tom qab noj qhov ncauj. Nws yog siv los tswj cov kab tsuag nplooj, muaj kev tswj hwm zoo rau cov yoov, kuj tseem siv tau los tswj cov yoov, thiab tseem tuaj yeem tiv thaiv thiab tswj Lucilia sericaria ntawm cov yaj thiab cov yoov ntawm cov quav qaib. Rau cov taum pauv, carrots, celery, dib, zaub xas lav, dos, taum pauv, kua txob ntsuab, qos yaj ywm, txiv lws suav nrog 12-30g / 100L kev kho mob, lossis 75-225g / hm²; Cov koob tshuaj siv rau hauv av yog 200-1000g / hm², thiab cov nyhuv tuaj yeem khaws cia txog li 8 lub lis piam nrog cov koob tshuaj siab. Nws tus qauv isotope tuaj yeem siv rau kev tshuaj xyuas kev sim los ua cov kab ntsuas calibration, tsim kom muaj kev sib raug zoo rau cov qauv tiag tiag, thiab ntsuas qhov tseeb thiab qhov tseeb ntawm cov txiaj ntsig tshuaj ntsuam xyuas tshuaj.

3, Qhov sib txawv ntawm cov qauv tshuaj lom neeg

Lub npe tshuaj ntawm ob qho tib si yog N-cyclopropyl -1,3, 5-triazine-2,4, 6-triamine, uas qhia tias ob qho tib si yuav yog tib yam khoom thiab muaj tib lub qauv tshuaj.

4. Qhov sib txawv ntawm cov txheej txheem ua haujlwm

Ob leeg ntawm lawv koom nrog 1,3, 5-triazine pawg ntawm cov tshuaj tswj kev loj hlob ntawm cov kab, uas tuaj yeem ua rau muaj kev cuam tshuam ntawm cov kab diptera thiab cov pupae, thiab txwv tsis pub lossis tsis tiav cov neeg laus tshwm sim. Ob leeg ntawm lawv ua lub luag haujlwm los ntawm kev txwv tsis pub cov synthesis ntawm chitin thiab dihydrofolate reductase, yog li cuam tshuam rau kev loj hlob thiab kev loj hlob ntawm cov kab.

5. Qhov sib txawv ntawm qhov ntau thiab tsawg ntawm daim ntawv thov

Ob qho tib si feem ntau yog siv los tswj cov kab diptera, xws li cov nplooj miners, yoov thiab lwm yam kab tsuag, hauv kev tswj cov yaj ntawm Lucilia sericata, cov kab larvae ntawm cov qaib dung kuj zoo, thiab tuaj yeem siv rau cov nroj tsuag ornamental, zaub thiab lwm yam qoob loo tswj kab tsuag.
