Yuav ua li cas yoov txiv hmab txiv ntoo tshwm yog tias lub qhov rais kaw, txhua yam huv si hauv tsev, tsis muaj dampness? Thiab lawv yuav ua li cas thiaj paub tias muaj txiv maj phaub hauv tsev? Tab sis qhov nthuav tshaj plaws yog tias cov qhua tsis tau caw tuaj yeem pom hauv koj chav tsev txawm tias lub caij ntuj no.
Txoj kev ntxhov siab Drosophila. yoov tshwm hauv tsev li cas?
Drosophili - qhov tseeb txhais los ntawm Latin ntawm kev qhia "hlub noo noo."

Feem ntau, muaj ntau hom Drosophila, txhua tus nyiam nyob hauv ib cheeb tsam. Feem ntau ntawm cov kab me no tsuas pom muaj nyob qhov twg xwb.
Kab nyiam noj paj nectar, birch, oak, ntoo thuv, rotting zaub thiab txiv hmab txiv ntoo, caw, npias wort, mis nyuj, lawv tsis disdain rotten.cactus. Cov yoov no noj txhua yam uas muaj cov poov xab. Cov neeg laus noj thiab nteg qe.
Drosophila hauv tsev? Kab mob tshwm sim li cas, thiab yuav ua li cas kom tshem tau yoov? Cov kab no muaj lub voj voog luv luv ntawm kev tig mus rau hauv yoov los ntawm lub qe, feem ntau siv li 10 hnub. Cov larvae molt peb zaug thiab tig mus rau hauv ib tug pupa. Thaum xub thawj, tus larva tseem nyob ntawm qhov chaw ntawm cov zaub mov, tab sis maj mam nkag mus rau hauv, qhov twg nws nyob mus txog rau pupation. Yog li ntawd, rau lo lus nug: "Drosophila yoov - lawv tuaj qhov twg?" - koj tuaj yeem teb: "Los ntawm cov khoom noj." Thaum pupation tshwm sim nyob rau hauv qhov nruab nrab nutrient, ib tug yoov tawm, uas, nyob rau hauv lub thib ob hnub, muaj peev xwm yuav pib mus multiply. Ib tug poj niam tuaj yeem tso tau txog li 1,500 lub qe hauv nws lub neej, thiab nws nyob tau li ib mus rau ob lub hlis.
YKev faib tawm ntawm Drosophila
Kab nyob hauv qhov chaw ntub thiab tsaus. Cov yoov no nquag nquag tom qab hnub tuaj thiab thaum hnub poob. Lawv tsis ya zoo heev, yog li lawv tuaj yeem npog tsis pub tshaj 190 meters hauv ib hnub. Yog li ntawd, rau lo lus nug: "Drosophila yoov - lawv tshwm sim li cas?" - koj tuaj yeem teb tau tseeb tias lawv tsis ya los ntawm qhov deb mus rau qhov tsis hnov tsw ntawm zaub mov, lawv tsuas yog tsis muaj peev xwm xwb.
Nyob rau sab qab teb, yoov tuaj yeem nyob hauv vaj txiv hmab thiab vaj txiv ntoo, hauv cov chaw tsim khoom ua kua txiv hmab txiv ntoo, cawv txiv hmab, kua txiv hmab txiv ntoo. Drosophila feem ntau pom nyob rau hauv cov kaus poom kua txiv hmab txiv ntoo thiab txiv hmab txiv ntoo Hoobkas. Lawv tuaj yeem mus nrog cov khoom thauj.
Nyob rau hauv xwm, Drosophila pupae overwinter nyob rau hauv av, uas yog nplua nuj nyob rau hauv rotted organic teeb meem. Txawm li cas los xij, lawv tuaj yeem overwinterib sab ntawm ib tus neeg, hauv tib lub tsev cog khoom lossis cov chaw tsim khoom, hauv lwm qhov chaw uas muaj qhov kub thiab txias, qhov chaw muaj kab mob ntawm cov yoov tshaj plaws tau pom.
Thiab thaum txiv hmab txiv ntoo ya mus rau hauv ib lub tsev, txhais tau hais tias lawv twb nyob hauv tsev lawm, tib neeg tsis pom nws. Yog li, txiv hmab txiv ntoo yoov - lawv tshwm sim li cas hauv chav tsev? Kab qe tuaj yeem nkag mus rau hauv tsev nrog cov zaub los yog txiv hmab txiv ntoo, lub ntiaj teb ntawm khau lossis hauv cov plaub hau tsiaj. Nws tsis yog qhov tsis yooj yim rau cov txiv hmab txiv ntoo ua rau lawv cov zes hauv cov av hauv tsev.
Thiab feem ntau, tus neeg lub tsev yog qhov pub rau cov txiv hmab txiv ntoo yoov thiab larvae. Tom qab tag nrho, nws tsim nyog tso lub thoob khib nyiab hauv tsev rau ib hnub ntxiv lossis tsis ntxuav nws, nchuav cawv txiv hmab, mis nyuj lossis npias rau hauv pem teb, nchuav nplooj tshuaj yej rau ntawm paj - tos kom ya me me tuaj xyuas.

Yoov yoov - lawv yog leej twg? Vim li cas yoov tom tib neeg thiab tsiaj?
Lub caij nplooj zeeg ze zuj zus, qhov mob ntau dua cov yoov tom. Qee lub sij hawm nws zoo li cov no tsis yog kab me me, tab sis tus Tsov tiag tiag tau tom koj txhais ceg. Tshwj xeeb tshaj yog thaum koj pom ib qho kev thab plaub uas lig dhau lawm thiab muab sijhawm rau nws los npaj "kev tawm tsam" tag nrho. Tab sis vim li cas yoov tom? Puas yog nws zoo siab heev rau lawv tsim txom cov neeg dawb huv? Los yog muaj lwm yam, tseem ceeb tshaj yog vim li cas?
